So we decided to try making a few tables and chairs.” John got married sixmonths ago, and like many young people these days, they arestruggling to make a home at a time when the cost of living is very high. The Rosses took a two-week course for 280 at a night school. Now they build all their furniture and make repairs around the house.Jim Hatfield has three boys and his wife died. He has a full-timejob at home as well as in a shoe making factory. Last month, he received a car repair bill for 420. “I was deeply upset about it.Now I’ve finished a car repair course, and I should be able to fix the car by myself.”John and Jim are not unusual people. Most families in the US aredoing everything they can to save money so they can fight the high cost of living. If you want to become a “do-it-yourselfer”, you can go to DIY classes. And for those who don’t have time to take a course, there are books that tell you how you can do things yourself.16. Why did John Ross decide to build their furniture instead of buying it?17. According to Jim, who should be able to fix his car?18. For those who don’t have time to take a course, how can they learn to become “do-it-yourselfers”?Passage 2Most of us spend high school dissecting frogs and feeling awkward at the occasional dance, but a small group of students in Spain got to dosomething far cooler with their educational time: they sent a digital camera into space. A teacher and four students from IES La Bisbal School inCatalonia, Spain bought a 60 balloon and fixed an 80 digital camera to it, then sent it up into the sky to capture some high-altitude pictures.The team only wanted to see if they could get their homemade weather balloon to fly to 30,000 feet, which is the altitude that most commercial aircraft fly at. But the balloon just keptclimbing until it was 20 miles above the Earth, at the very edge of space. Tracking the balloon’s progress using meteorological sensors and Google Earth, the team kept track of atmospheric conditions and snapped a handful of amazing pictures.The four students and their teacher completed the experiment in February 2009. The teambuilt the electronic sensor components themselves, then placed them, along with the camera, into a protective housing before releasing therig into the sky.The balloon rose to an altitude of over 100,000 feet before falling back to the ground. The team traveled over 10 km to find the balloon and equipment. They were amazed to find that the equipment was stillemitting a signal, despite being exposed to some extremely harsh conditions.19. What did four students in Spain do with their educational time?20. What’s the altitude that most commercial aircraft fly at?21. When did the team complete the experiment?22. After traveling 10 km to find the balloon and equipment, whatwas the team amazed to find?Passage 3Despite controversy, direct-to-consumer genetic tests are becoming more popular. This kind of genetic tests is more like a do-it-yourself diagnosis. It is becoming almost as easy as taking a home pregnancy test. People can use their credit card to order a set of tools on the Internet, use a brush to remove a few cheek cells, return the tools and receive a report via e-mail. DTC tests costfrom a few hundred to a few thousand US dollars, and are availablefor more than 800 conditions ranging from breast to cancer.The US population may be particularly ready for DTC testing becauseit has a do-it-yourself ethic and is accustomed to paying out of pocket for healthcare services. Companies that offer genetic tests are enthusiastic about the prospects of widespread DTC testing. They argue that genetic testing is no different from non-DNA tests. But not everyone is thrilled about the ease with which consumers can takegenetic tests. Some people worried DTC genetic testing poses dangers to the public. Patients may experience psychological harm since they might not understand what the results mean to them.The lack of regulation in the Internet may also result in a factthat the Web gives you information that could be very misleading andpotentially harmful to you. However, many people are comfortable with the lack of regulation as long as a doctor can help them. So what does the future hold for DTC genetic testing? We cannot expect widespread do-it-yourself screening for genetic disease in the years ahead. But we can predict a growth in DTC genetic testing for certain diseases and fully expect that this kind of technology is going to be with us.23. What do we know about direct-to-consumer genetic testing?24. What is one of the reasons that some people worry about the DTC genetic testing? 25. How is the future of DTC genetic testing?Section C26. available27. unique28. Specializing in29.

Book 4 Unit 2 Part D 听力原文Section A1. M: Good morning, Madam, could you tell me how old you are?W: Well, I don’t remember, doctor, but I will try to think. When I married, I was eighteen years old, and my husband was thirty. Now, my husband is seventy, I know.Q: How old is the lady?2. W: Hey, have you heard about this? The film star, Janice, was followed by paparazzi all the time. Isn’t it terrible?M: Everyone’s got a right to some privacy, but if you want to be famous, you have to accept the press and the media.Q: What does the man mean?3. W: How did you like the president’s speech tonight?M: Unfortunately I got home too late to watch it.Q: What are the two speakers talking about?4. W: I’ve noticed that you haven’t been talking to your roommate lately.M: It is supposed to be private, but you’ve got that right. And it’ s g oing to be a long time before I feel comfortable with him again.Q: What does the man mean?5. W: So, what did you think about the discussion at lunch? I didn’t realize people have such strong feelings about privacy.M: Are you kidding? That subject always touches a nerve.Q: What does the man mean?6. M: So, you and Julia are no longer roommates. I’m not surprised. Y ou two never did things very compatible.W: Yeah. Well, it’s not that we didn’t get along. We just didn’t have much in common.Q: What can be inferred about the woman?7. W: So how did you make out with your private German lessons last month? Any improvement? M: Let’s just say it was money down the drain.Q: What does the man mean?8. M: I can’t seem to find my calculator. Did I lend it to you by any chance?W: No, but you are welcome to use mine if you want, as long as I get it back by Thursday.Q: What does the woman mean?Conversation 1M: Good morning, Professor Harkens. I hope I am not disturbing you.W: Not at all, Tom. Come right in. I’m always in my office in the morning.M: I thought I’d get an early start on my research paper and would like to discuss my topic withyou if you have a moment.W: Of course. I recommend that all my students should discuss their topics with me before they begin their research. What do you want to work on?M: I was especially interested in your lecture on dinosaurs and the apparent mystery surrounding their extinction. I’d like to explore that question, but I’m not too sure how to go about it.W: Well, according to the most widely held theory, the dinosaurs died out because of the sudden cooling of the earth’s temperature. Y our textbook summarizes the conclusion of several paleontologists on this point.M: Didn’t you also mention a second theory in your lecture? That dinosaurs may simply have been replaced by mammals gradually and might not die out as a direct response to the cool weather?W: Y es. V an V ellen and Sloan are proponents of this theory. And I’ve put some of their articles on reserve in the library.M: V an V ellen and Sloan? I’d better write that down.W: Let me know how your work progresses, Tom. If you should run into any problems, be sure to stop by again.9. Who are the two speakers?10. What is the main focus of Tom’s research?11. Who most likely are V an V ellen and Sloan?Conversation 2W: Hew! This rowing is hard work. Let’s have the boat toward the old lighthouse now.M: Good idea. We can rest there for a while and eat our lunch. Then we can climb to the top platform where the light is before we visit the museum at the base of the lighthouse tower.W: Whenever I came out here, I thought about the family who used to live on the little island and take care of the light every night. What a lonely life that must have been!M: Y eah, to help ships find their way along shoreline, at night, they had to constantly make sure that the windows up around the light were clean and free of ice and snow.W: Dirty soot must have be en a problem. Didn’t they burn candles up there?M: This one used to have a kerosene lamp. But they changed over to electricity around 1920, I think.W: In New Port, Rode Island, people talked about a woman who was a lighthouse keeper for over 50 years. Ida Louise was her name. She saved a lot of people from dying in ship wrecks.M: Was her lighthouse out on an island like this one?W: On one even smaller and further from land. In stormy weathers, it was pretty dangerous for small boats.M: I understand the United States Coast Guard takes care of the most modern lighthouses.W: Y eah, but the light is automatic nowadays. The lighthouse is still a friendly sight at night though.M: Here we are. This lighthouse is the friendliest sight I’ve seen today. I’m exha usted.12. What are the people doing?13. What was a major problem for every lighthouse keeper?14. Why was Ida Louise famous?15. How does the man feel at the end of the conversation?Section BPassage 1More and more electronic devices and services in our daily life mean we have too many passwords and numbers to remember. Passwords help us protect our wealth and privacy; however, they also bring us a lot of troubles.Every day I need to remember much useless information. Every morning I turn on my cellphone — it needs a password. I get to work and I have to have access to my computer with a password. Like many people in Britain, I have two bank accounts. One needs a five-digit number and a password; the other needs a six-digit number and a memorable place name. I have an online savings account that needs a different password from the password for my bank account.Even if you never use a computer, you can be hit by the password overload. Look in your wallet. Y ou probably carry four or five credit cards. In these days of chip and pin, these are virtually useless if you do not have the magic four-digit numbers. The banks tell you not to have the same number for all your cards. Give me a break. Am I going to carry five different random four-digit numbers in my head? After all, I’m not Good Will Hunting.I’ve tried systems to help me remember —such as using the names of favorite films or members of my extended family; but none seems to work. So what is the solution?16. What do passwords bring to us?17. Which of the following does NOT need a password?18. What has the speaker tried to do to remember his passwords?Passage 2Internet is threatening our privacy. In the past, if a shop manager wanted to know you better, he had to rely on a good memory for detail. They came out from behind the counter to give you personalized service, browsed the shelves with you and made recommendations.In this digital marketplace, the “shop manager” may actually be a machine. It searches in its memory of information about you, analyzes it and creates a clear portrait of what you are likely to buy and do in the future. Not all companies approach personalization in the same way. For some websites, the approach is direct: they ask you to take a survey about what you like, and then make offers that match your interests. Another way is through IP addresses, the electronic place from which you browse the Web. and many other sites also compare individual’s browsing and buying habits to those of thousands and millions of other consumers in their databases. Using a technique called collaborative filtering, they can find out your likely interests. This is based on what they know about what like-minded people buy or do.But this new use of Internet begins to trouble some computer users. They worry that advertisers can track their private information without their knowledge, and that files about them might be put to ill use somehow, or shared with wrong people. Sometimes they just don’t like being watched.19. Which of the following do traditional shop managers NOT do to know their customers?20. In the digital market, which of the following does the “shop manager” NOT do?21. How does know about its customers?22. Which of the following troubles some computer users?Passage 3Every day you share personal information about yourself with others. It’s so routine that you may not even realize you’re doing it. Y ou may write a check at the grocery store, charge tickets to a ball game, rent a car, mail your tax returns, buy a gift online, call home on your cell phone, schedule a doctor’s appointment, or apply for a credit card. Each transaction requires you to share personal information: your bank and credit card account numbers; your income; your Social Security Number (SSN); or your name, address, and phone numbers.It’s important to find out what happens to the personal information you and your children provide to companies, marketers, and government agencies. These organizations may use your information simply to process your order; to tell you about products, services, or promotions; or to share with others.And then there are unscrupulous individuals, like identity thieves, who want your information to commit fraud. Identity theft — the fastest-growing white-collar crime in America —occurs when someone steals your personal identifying information, like your SSN, birth date, or mother’s maiden name, to open new charge accounts, order merchandise, or borrow money. Consumers targeted by identity thieves usually don’t know they’ve been victimized. But when the fraudsters fail to pay the bills or repay the loans, collection agencies begin pursuing the consumers to cover debts they didn’t even know they had.23. In which of these actions may people NOT reveal their private information?24. What may organizations use your private information to do?25. When will the consumers notice that their private information was stolen?Section C26. launched27. previously28. critical29. seminars30. genetic31. collaboration32. perform33. accusing him of34. added a clause to35. walk out。

Do you think so?W: I think parental approval is critical for marriage because it creates unity in a family.Q: What do we learn from the conversation?2. M: Is it possible to be married and to be free?W: If you take marriage seriously, then freedom is impossible. If you take it non-seriously, then you can be free.Q: What do we learn from the conversation?3. M: I don‟t know if you remember, b ut it was on this very day last year that we tied the knot. M: How could I ever forget？I love you more than the day we got married.Q: What‟s the special day today?4. W: What would you do if you were in a relationship with someone you didn‟t love any more? M: One word, divorce.Q: What trouble might the woman have？5. M: It‟s really hard to believe that George‟s engaged. Where did he and his fiancée meet?W: At some cocktail in San Francisco, he took to her immediately. I mean, they really hit it off. Q: What can we learn from the conversation?6. W: Eddie, you‟re going to be a father!M: That‟s wonderful news! As an expectant mother, you need to take great care of your health. Q: What is the probable relationship between the two speakers?7. M: Do you know that, a long time ago, weddings were arranged by the parents? The bride and groom only met on their wedding day.W: Really? People don‟t do that now. They believe in free love.Q: How did the bride and groom get to know each other in the past?8.M: They‟re playing the Wedding March. Y our eyes are filled with tears.W: Mary looks so beautiful in the wedding gown, and I recall the moment that I was a bride.Q: Where does the conversation happen?Conversation 1M: Hey, Mary. What are you doing?W: I‟m reading the newspaper. It says a study found changes in the way that American wives and husbands share economic responsibility for their families.M: What is the new economics of marriage in America?W: The study found a big increase in the percentage of married women who earn more money than their husbands.M: Is there any specific data given in the study?W: Y es. 22% of the wives earned more than their husbands during the most recent year of the study. Thirty-seven years ago, just 4% of wives were top earners.M: That‟s a big change. It‟s widely believed that money is number one reason for arguments between married couples.W: I think unequal incomes are no reason for tensions. It is important to look at family life as a whole.M: I agree with you. Both partners have to give their time, effort and, in many cases, income for the good of the family.W: Y ou are so right! Good marriages bring together the skills and ideas that make a family work.9. What are the man and the woman mainly talking about?10. According to the study, what is the percentage of wives who earned more than their husbands during the most recent year?11. What is the woman‟s attitude towards unequal incomes between husbands and wives?Conversation 2W: Hey, Tom. What‟s that in your arms?M: Books.W: What‟s that for?M: My teacher asked me to write an article about college students marriage. Y ou know that many college students are getting married nowadays. Could you please say something about that? I am looking for opinions about that topic.W: My pleasure. Chinese government allows on-campus students to get married before they complete their course. But I think people get married during their college life is not so good.M: Can you tell me why you are against college students marriage?W: Because for on-campus students, their main task is to learn. If they are married, their school work must be affected and they may not graduate favorably. Furthermore, to be married, they must consider many extra problems, such as time to get together, place to live, the cost of home maintenance, birth control, etc.M: I couldn‟t agree wit h you more. They are still too young to think about it. I think it is unnecessary to ban campus marriage, but it should not be advocated or encouraged.W: So, a reasonable mind is especially needed to deal with the problem.M: OK, I have written what you have said down. Thank you so much.12. What topic did the man‟s teacher ask him to write about?13. What is the woman‟s attitude towards college students‟ marriage?14. If on-campus students choose to be married, what factor do they need to take into consideration?15. What is the man‟s attitude towards campus marriage?Section BPassage 1Having been married for more than 40 years, I can attest to the truth of the followingstatement: to excel in the art of domestic argument, one must master the art of losing.Modern psychologists are taken with the “win-win” solution. But in marriage, success resides more in “lose-lose” solutions. Out of these, both parties can win. For in the love configuration, losing gives a gift that always returns.One day shortly after my wife and I were married, we set about picking new living-room wallpaper from a book of samples. My taste and hers were at odds. “I like this one,” she said. “That looks so ugly. I wouldn‟t hang that in hell if I were the devil.”As the argument wen t on, my wife suddenly slammed the book shut. “There are over two hundred samples in this book,” she declared. “I say we spend our energy finding one that suits us both, instead of bickering over the ones we don‟t like.”And that‟s how we settled it. Event ually we found a pattern we both liked. The “wallpaper book” became our symbol for settling the myriad issues that arise in marriage. “Well,” she‟d say when we couldn‟t agree on furniture or a place to vacation, “there are plenty of samples in the wallpape r book.”So remember: if you want to win arguments at home, learn to lose them.16. According to the speaker, what leads to a successful marriage?17.What was the origin of the argument one day shortly after the speaker got married?18. What was the result of the argument?Passage 2Married couples are more likely to live to an old age than their divorced, widowed or un-married counterparts, a US study claims.Research published today in the Journal of Epidemiology and Community Health shows that people that never marry are almost two-thirds more likely to suffer from premature death, with single men more adversely affected than women.By analyzing census data involving 67,000 individuals between 1989 and 1997, scientists from the University of California, Los Angeles (UCLA), found that in 1989 about half of respondents were married, two-fifths had either been divorced or widowed and 20 per cent were not married.Although the researchers admit that by 1997 the greatest contributing factors tow ards mortality were old age and poor health, whether people were married or not had a significant impact on whether people were still alive, even after taking age, health and other factors into consideration.The UCLA research team say they were surprised by the fact that non-married people in good health were more likely to have died during 1989 and 1997 than less-healthy individuals.The researchers explained that the unmarried group of people were found generally to be in better physical condition than their married peers, as well as drinking less alcohol and exercising more.The authors of today‟s report suggest that marriage represents a connection with social life; while not getting married may be strongly linked to “severe isolation”.19.According a US study, which group of people are more likely to live to an old age?20. How many respondents were involved in this US study?21. What is NOT a factor contributing to mortality?22.Why were the researchers surprised by the fact that non-married people in good health were more likely to have died than less-healthy individuals?Passage 3Priscilla Nangurai retired as a teacher in 2005. Today, at the age of 62, she could be living a quiet life in retirement. Instead, she leads an organization at her home called GRACE — the Girls Rights, Attention, Care and Rescue Center. She tries to rescue Masai girls from early marriage and make sure they get an education.In the traditional culture of the Masai people, fathers often promise their young daughters in marriage to older men. Most girls are between the ages of twelve and fourteen, with some even younger.Priscilla Nangurai says the problem begins when a girl gets “booked” when she is very young, or not even born yet. “Booking is when a parent or a ma n wants to marry from a certain family. So he can go to the family, and if there are little girls there, he will book. If one of the wives is expectant, he will say, …I want something from this womb.‟ And he‟s allowed to do that. ”A fourteen-year-old girl named Roseline has been at the rescue center since 2008. At the age of four she was booked to a man who she thinks was about sixty to seventy years old.Masai culture calls for the man who wants to marry a girl to start paying the girl‟s father once the booking has been made. Traditionally the payment is made with cows, but today money can also be exchanged.Since 1986, Priscilla Nangurai has rescued more than 700 girls. She now has 15 girls at her center, and she is building a dormitory to house up to eighty girls.23.Why did Priscilla Nangurai build up GRACE instead of living a quiet life in retirement?24.What can we learn fro m the passage about “booking”?25. When should the man who wants to marry a Masai girl start paying the girl‟s father?Section C26. permanent27. cut short28.

Short conversationsConversation 1W: The only thing I can do at night is to lie in bed and read, preferably while also eating a snack. Inever have time for exercising.M: Don’t think it’s worth exercising only if you can run five miles or if you can bike for an hour.Even going for a 10-minute walk is worthwhile.Q: What advice does the man give to the woman?Conversation 2W: Hi, Mark, I’ve gained quite some weight recently. So, how can I eat healthily at social events?M: Well, drink a full glass of water before you go. Focus mainly on fresh fruit and vegetables orbread with whole grains. These will help you stay feeling full.Q: What can we know about the woman?Conversation 3W: I heard that in South Africa smoking is banned in all enclosed public spaces. M: Yes, that’s right. But pubs and bars with separate, enclosed smoking rooms are excluded fromthe ban, and most restaurants provide smoking sections, either indoor areas with good aircirculation or outdoor open areas.Q: What can we learn about the smoking rules in South Africa?Conversation 4M: So, your research shows that even when children are not direct targets of violence in the home,they can be harmed by witnessing its occurrence?W: Yes, that’s right. For example, they can suffer immediate and permanent physical harm.They can also experience short- and long-term emotional and behavioral problems. Q: What are the two speakers talking about?Conversation 5W: Skipping breakfast is common among people who are trying to lose weight, but it doesn’tseem to be a successful strategy.M: No, it isn’t. While any breakfast may be better than no breakfast, a healthy breakfast can besomething simple like a hard-boiled egg, a piece of 100 percent wholegrain toast along with acup of 100 percent fruit juice.Q: What is recommended for a healthy breakfast?Long conversationM: I love working out!W: Ugh! You’re sweating all over the floor …M: I just ran five miles! A friend told me about this great park on Jefferson Street. I love exploringnew parks!W: I try running at the gym three days a week, but it’s so boring looking at the TV monitor or thewall in front of me for an hour.M: You should run outside! Being in nature, enjoying the beautiful flowers and the trees, I feel mymind relax and the stress just falls away.W: It is nice outside. My mom loves t’ai chi and a nearby t’ai chi group meets every morning at 6a.m. I’ve tried going, but it’s too early for me to get out of bed …M: T’ai chi is really good. You need some kind of exercise. It’s unhealthy for you to sit in front ofyour computer all day, every day!W: Well, I recently spend my weekends away from my computer.M: Oh really? And what have you done recently that didn’t involve a computer or TV screen?W: Pandas! I just went to the San Diego Zoo with my sister on Saturday! They have one of thebest panda exhibits in the US. The mother panda is from Wolong, China, and had had six babypandas by 2012 since arriving at the San Diego Zoo in September of 1996.M: Oh, I bet baby pandas are amazing! Hey! Maybe you should get a zoo membership and gojogging in the zoo!W: A zoo membership! Now that’s a great idea! I love the San Diego Zoo. It’s near my house, Ican get good exercise and I can watch the baby pandas grow up!Passage 1Have you ever felt you don’t have enough hours in the day? Or that you’d give anything for awhole day to catch up with yourself? Well, here are some ideas that work for me. First of all, make a to-do list every day and set clear priorities. The trick here isn’t making thelist; that’s the easy part. The trick is making the priorities. I look at my list and put a star next toanything that is really urgent. Then I put the number “2”next to anything that will just take acouple of minutes. I actually do these quick tasks before I get on with the urgent ones; it’s a bitlike clearing off the top of your desk before sitting down to write that important letter.Second, know when is the most productive time of day for you and do your work orstudythen. One of the shocking discoveries I made about myself is that if I get up at 5 a.m., I can do aday’s work and even fit breakfast in before half past nine. Of course, if you are an early bird, it canbe difficult to accomplish tasks that involve phoning “night owls”, but that’s what email’s for!Finally, do not let your inbox run your life. I just realized recently how frequently I interrupted my real work to check my inbox and respond to the most trivial of emails. So, now Ionly open it when absolutely necessary and this saves me hours. If your work depends on youbeing constantly accessible by email, then you can’t do this; but be honest and ask yourself, “Am I an email addict?”With these simple, practical techniques, you will become more efficient, less stressed and beable to win some “me-time”for yourself.Short conversationsConversation 1W: So this is your last year in college. Have you ever thought about what you’d like to do aftergraduation?M: Well, I really don’t know. The job market seems to be improving, so I may look for a jobsomewhere. But I am also interested in applying for graduate school.Q: What are the two speakers talking about?Conversation 2M: Do you remember Linda we met a while ago at Susan’s birthday party?W: Linda? Do you mean the lady who you said was a nurse in the community hospital before herretirement? Yeah, I remember. She looks very young for her age.Q: What does the woman think of Linda?Conversation 3M: I wish I could retire tomorrow. Then I would not need to worry about work. W: I don’t look forward to retirement. I’m afraid of getting old –my body will slow down, andmy children will be away. I dread losing independence and living in loneliness. Q: What makes the woman afraid of getting old?Conversation 4W: I consider my early 20s to be the prime time of my life. How about you?M: I couldn’t agree with you more. That’s no doubt the golden period. You are young andenergetic. You are free to pursue your passion. The best thing is that you have a wealth ofopportunities to explore.Q: What does the man like best about being in his early 20s?Conversation 5W: Hi, John. You are taking Law 201 this semester, right? How do you like it?M: Yeah, it’s a great class. We’ve looked at several cases of age discrimination at work. Suchcases are very interesting because they are rarely clear-cut and court decisions can be rathercontroversial.Q: What does the man say about age discrimination cases?Long conversationM: Nancy, time to make a birthday wish!W: I wish ... hmm. OK! I want a high-paying job, a husband with a perfect face and body, and abig house ... with a swimming pool!M: Wow, Nancy! Those are your three wishes?W: Of course! If I have those three things, I’ll be happy!M: Now, Nancy. Let me tell you my story, and you may see things differently.W: “See things differently?”What do you mean, Uncle Charlie?M: Here is what I once experienced in life. When I married, 32 years ago, we had a happymarriage, a beautiful house, two expensive cars, and $200,000 in the bank!W: See, just like now!M: Wait! I would suggest three different wishes!W: Well ... What would you wish for? You’re older and wiser!M: What happens if you lose your job, lose your house, and your husband becomes sick? I suggestthese three wishes: patience, courage and love!W: Patience, courage and love?M: Yes! If you have patience and courage, you and your husband will have good jobs and a nicehouse. And if you have true love, you and your husband will be beautiful to each other nomatter how old you become together.W: This is good.M: Within six years of our marriage, we had three beautiful children, but we lost our jobs, ourhouse, all our money, and then I got really sick for nine years. But we didn’t lose anythingtruly valuable, because we always said: “Wherever the five of us are together, we are at home!”And, little by little things did improve, and I finally got well. Patience, courage and love!These are what make life full, strong and happy!W: Hmm, I will remember. Patience, courage and love! Thanks, Uncle Charlie!Passage 1If you think that you have to live up a remote mountain in order to live a long and healthy life,a religious community in Loma Linda, California, may prove you wrong. Its members are a groupof Christians known as the Seventh-day Adventists. The Adventists enjoy a much higher lifeexpectancy than average Californians. Adventist men can expect to live about seven years longerthan other Californian men. Adventist women are likely to live around four years longer than otherCalifornian women. The Adventists also act much younger than they are and see doctors muchless than ordinary people.So what’s the secret of the Adventists’longevity? It is not all in their genes. Nor istheir goodhealth a mere accident. The Adventists live longer partly because they have a vegetable-based diet.Around 35 percent of them are vegetarian, and around one half eat meat only rarely. Tobacco andalcohol consumptions are discouraged. So are rich or spicy foods, meat, and drinks containingcaffeine. The Adventist diet is high in fruit and vegetables. It also includes plenty of whole grains,nuts, seeds and beans, and water is the drink of choice.The longevity of the Adventists is also related to their lifestyle and natural environment. Theybelieve in having regular exercise, helping others, and maintaining strong social and familial ties.They live in a mild climate with warm summers and cool winters. Interestingly, the air quality ofLoma Linda, however, is not as good as in other longevity hot spots. This should give us all hope,as it suggests that we don’t have to have every single factor in place in order to achieve excellenthealth. Despite this, the Adventists’good health certainly provides strong evidence that diet andlifestyle choices have a great impact on health and longevity.Short conversationsConversation 1W: I really need a holiday, so I’m going camping with some friends. What are you doing over thesemester break?M: I haven’t got any plans yet. I don’t really have enough money to fly home. I suppose I couldget a part-time job and earn some money, or maybe I could start studying for next semester.Q: What is the woman going to do over the semester break?Conversation 2M: I heard that you quit your swimming lessons. But you have paid $120 for them. W: Ah, it’s all these yoga sessions. I just couldn’t fit them all in. What’s more, I got the majorityof my fees back because I quit immediately after the first day.Q: Why did the woman quit her swimming lessons?Conversation 3M: Shall we spend our weekend in Singapore? We can leave Friday afternoon so as to have dinnernext to the river and enjoy fireworks at the shore!W: I’d rather go on Saturday. My aunt will drop in on Friday evening. We haven’t seen each otherfor a couple of years.Q: Why doesn’t the woman want to leave on Friday?Conversation 4M: What do I need to bring for our camping trip to the national park?W: Well, we’ve bought the food and rented a van. It’s a camping vehicle with a fridge and cookingequipment. I think you will need a warm sweater or jacket for the evenings.Q: What does the woman suggest the man bring for the camping trip to the park? Conversation 5M: Have you confirmed your booking at the hotel in Sydney? With only three days left before ourtrip, I hope everyone is as ready as I am!W: Not yet. But I’d better call them before we start our vacation. During this time of year theyalways get quite busy.Q: What will the woman probably do before the vacation?Long conversationM: Rebecca, I just learned of an amazing park right here near our city!W: Really? Is it a nature park or an entertainment park?M: It’s a beautiful nature park, located 15 miles from our home.W: What’s it called?M: It is called Big Sky Park and has nice walking trails and camping sites!W: Bill, this is perfect! We can have a vacation and still keep saving money to visit my familysometime. But, can we get to Big Sky Park without a car?M: Yes, easily. We just take the No. 32 bus that goes right to the park. The only problem will begetting all of our camping stuff with us on the bus.W: Well, I did just buy that new cart to help carry groceries home on the bus, plus we have yourbig backpack. Together, I think we will be fine. All of our camping equipment should easily fiton the bus.M: Good. Good! I know we can make it a really special weekend. I have longed for a time whenwe could walk alone together in the quiet beauty of nature. I’m so, so happy to have thischance to be with you at the park.W: I know me too! I know what I’ll do! I’ll pack all of our favorite food, and I’ll bake a smallchocolate cake. Your favorite! Then we can drink tea and eat the chocolate cake around acampfire. I’m so happy you found Big Sky Park. I can’t wait, just two more days for theweekend to come!M: I’m so happy as well. Big Sky Park will be wonderful. The fire, the dinner and spending timewith you make me such a happy, happy man, Rebecca!Passage 1A new museum entirely dedicated to laziness has opened in the capital city of Colombia. Butyou have to hurry if you want to see the exhibits and find out about being lazy because theexhibition lasts only for one week. The unusual show displays a whole range of things such assofas, beds and anything that makes you feel like taking a rest. There are also plenty of televisionsfor those visiting couch potatoes to watch as they move around relaxingly in the museum.It is no coincidence but rather an intentional decision for the museum to have opened rightafter the holiday season. The idea is for people to think about laziness, and perhaps change theirbehavior and lifestyle throughout the rest of the year. It offers a practical experience to make usthink about laziness in our high-speed, fast-paced societies.The museum’s founder Marcela Arrieta said she wanted people to rethink about laziness anddecide whether it really is a bad thing. She told the media that people today always think aboutlaziness as an enemy of work. For example, they may feel guilty if they sleep late, or they mayfeel they are wasting time after taking a nap or having a holiday.Ms. Arrieta may not be proposing that we should have a shorter working week, but she couldhave a point in that we do need more leisure time than our jobs allow us, and change our lifestyleto a type that is more relaxing. Besides, according to scientists, avoiding the pressure and stress ofwork can make us healthier and live longer. So, why not try out Ms. Arrieta’s advice for yourself,slow down, and think about being lazy?Short conversationsConversation 1M: I think the government could provide some money for homeless people to build their ownhomes. Homeless people would find it easier to get jobs if they had an address. W: It’s not a bad idea. But I wonder where the money will come from.Q: What does the man think the government could do?Conversation 2W: You see, some colleagues are not as active and efficient as usual and few have made anyprogress in their business recently.M: Why don’t we organize some social activities, such as a baseball match? Our colleagues canlearn to help and cooperate with one another.Q: What does the man suggest to change the situation?Conversation 3W: I need to go across town, but the traffic is so heavy at this time of day.M: When you take the subway, you don’t have to deal with traffic. I never drive home. Driving atthis time may be slower than walking.Q: What does the man suggest the woman do?Conversation 4W: Have you heard? Kate quit her job and went to Africa to work as a volunteer! M: Really? I really admire her courage. I think we should all extend an arm of help, love andcompassion to help poor people become self-reliant financially and psychologically.Q: What does the man think we all should do?Conversation 5W: You know there are many creative ways to reuse items. For example, old shoe boxes can beused for storage and plastic containers can be used for growing plants.M: I never realized that we could be so green. I just learned to recycle glass bottles. Q: What are the two speakers talking about?Long conversationW: Hey, John! Everything OK? You look upset.M: Oh, hi Kate. I was in the cafeteria eating alone. James from accounting walked by, sat down toeat at the table right next to me –didn’t say a single word to me. I wondered why. W: Is that the main thing stressing you out, John?M: No, I was silly to feel bad about that. What I am stressed about is my workload. My manager,Steven, is a great guy. He always counts on me to get the work done. But I have five meetingsthis week and two big projects to complete by next Monday. I don’t see how I can finish. I’mreally worried I’ll let my team down.W: I have some free time on Friday and over the weekend. I can help you with your extra work ifyou’d like. I know that feeling of being overwhelmed with work. It’s awful. I’d like to help.M: Really? You’d do that for me?W: Of course I will! John, a lot of us really admire your work. Some of us have asked to work onyour team. You’re a great example to us, John. You shouldn’t doubt yourself. I’m glad to helpout.M: Wow, Kate. Thanks!W: We could ... discuss it over dinner on Thursday. My treat!M: Wow. No ... I mean I get to buy dinner, Kate! How about the new restaurant on 6th Street, 365?It’s called 365 because it offers local, seasonal foods –fall, winter, spring, and summer –healthy choices with wonderful fresh fruits and vegetables. Let’s meet at 7 p.m. W: Sounds wonderful! Thursday, 7 p.m. at the new restaurant 365 on 6th Street. Perfect!Passage 1More than half of working Americans are dissatisfied with their jobs, according to a survey.That’s bad news for employers because workers’discontent can hurt productivity and hinderinnovation.Lynn Franco, co-author of the report, says Americans’job satisfaction is at its lowest level inmore than two decades: Only 45.3 percent of workers say they are satisfied with their jobscompared with 61 percent in 1987.The report was produced by the Conference Board, a non-profit organization that helpsbusinesses strengthen their performance. It is based on a survey of 5,000 US households. It showsa drop in satisfaction in many aspects of an employee’s work life, including interestin the job,dealing with co-workers and bosses, commuting and job security. As a group, neither youngpeople who are just entering the workforce nor employees who are about to retire, Franco says, arehappy with what they do.Only about 36 percent of workers under the age of 25 say they are currently satisfied withtheir jobs. And it’s not much better among baby boomers. Twenty years ago, more than 50 percentof baby boomers were satisfied. Today, that’s down to 46 percent.The most satisfied group of workers in the survey was those aged 25 to 34. Franco suggeststhat they may see some opportunities for upward mobility as baby boomers retire. The Conference Board survey also asked about the reasons behind job dissatisfaction. Thereare economic reasons such as wages, promotion policy and bonus policy that are sort of adding tothis level of dissatisfaction. In addition, workers are also dissatisfied with the benefits: vacationpolicy, family-related leave time, work schedule flexibility, and a variety of other factors as well.Short conversationsConversation 1W: I’ve read a lot about this young singer in the music press. She’s certainly creating a stir. Is shereally that good?M: She’s absolutely brilliant. Each of her performances has been a sell-out. Her mix of rap andfolk music is unique and awesome.Q: What does the man say about the singer?Conversation 2M: So here we are in Rome, Italy. In the next four days, we are going to have a full schedule.W: I’m so excited. Rome has been my dream city. I can’t wait to see the historical buildings, visitthe art galleries and eat real Italian pizza. By the way, shall we start with the famous CapitolineMuseums tomorrow?Q: What are the two speakers mainly talking about?Conversation 3W: Besides modern opera, which you are studying now, are there any other areas of the arts youenjoy?M: All sorts. I like pop music, and I very much enjoy pencil drawing. But what interests me mostis poetry, especially American poetry in the early 20th century.Q: What’s the man’s area of study?Conversation 4M: Hi. I am calling to inquire about the exhibit of ancient Greek sculptures you are now hosting.Could you please tell me the admission fee and the opening times?W: Sure. Admission is free. The opening hours are 10 a.m. to 4 p.m. Mondays through Thursdays,10:30 a.m. to 7:30 p.m. on Fridays, and 11 a.m. to 6 p.m. on Saturdays and Sundays. Q: How long does the exhibit open on Saturdays?Conversation 5W: Darling, let’s check out the reviews of this movie online. If it’s good, we should watch it.M: I think we should. To watch a silent movie is certainly not something common in modern days.The actors must have superb skills to attract the audience if they do not say anything.Q: What is special about the movie?Long conversationW: This feels like a dream ... The last time I was in San Francisco was 30 years ago, when I wasyour age, 15 years old. So much has changed in the city–but you know–many of the sites arejust the same.M: Wow! San Francisco is as beautiful as a picture! I can’t believe it! Let’s get going! Let’s lookat the map and take the streetcar to the Golden Gate Bridge.W: Yes, of course. But, wait–let’s just take a moment to look at the Golden Gate Bridge fromhere–up high on the hill. See how amazing the sun looks, shining on the bridge there highabove the water? Sometimes the best way to really enjoy something is to see it from differentangles and perspectives.M: Yes! Just beautiful from here! OK! Let’s get going! Wait! You know what, Aunt Lucy, I’mreally, really hungry! May we eat before we head out to see the Golden Gate Bridge?W: Yes, of course we can. We’re already here in Chinatown and near my favorite Chineserestaurant. Even after 30 years have passed since I last visited, it’s still busy and active.M: That’s great, Aunt Lucy!W: And, it’s right here!M: Wow! This is amazing! The man inside the window is making noodles by hand–just by pullingon the flour dough. I’ve never seen anything like it before. How?W: Yes, I know. It’s amazing, right? And the food is delicious, too! Sometimes the best way toenjoy culture is to simply slow down and truly experience it. We have five full days here inSan Francisco. Let’s go slowly and enjoy every moment!Passage 1The Mona Lisa is probably the most famous painting in the world. It was created by Leonardo da Vinci, the famous Italian artist, between around 1503 and 1506. The subject is thewife of a wealthy silk merchant of Italy. The woman’s husband requested Da Vinci to portray heras a celebration of their home’s completion and the birth of their second son. What is it about thispainting that has created such a lasting impact on the artistic world?One factor is the artist himself. Leonardo da Vinci was not only an artist, but also a scientist,an architect and an engineer. His knowledge of the human form came from the study of actualhuman bodies, so he was able to draw and paint it more accurately.Another factor is the material used for the painting. The Mona Lisa is an oil painting, butunlike other paintings, which are usually created on canvas, the Mona Lisa has a wood panel asthe surface. The use of a wood panel makes it possible for the work to have survived for centuries.Lastly, the style and techniques used for the painting make the Mona Lisa a masterpiece. DaVinci presented precise details in the subject’s hands and face. He applied a shadowing techniqueat the corners of her lips and her eyes, which gives her an unbelievably lifelike appearance. Healso created a background with aerial views and a beautiful landscape. His remarkable skills leftbehind no visible brush marks at all.All these factors–Da Vinci’s talent, the medium used for the painting, the style andtechniques applied in the work–contribute to the lasting and mysterious beauty of the Mona Lisa.Short conversationsConversation 1M: There is not much worth in reading the newspapers these days. They have more pages butfewer words that really matter.W: You said it! All you find in them are advertisements and celebrity gossip. I wish they coulddirect more attention to issues that are more important to society.Q: What does the man think of today’s newspapers?Conversation 2W: Hello. Today on Business Focus I am talking about knowledge management with Mr. AdamJohnson, the Human Resources Manager of a multinational company. Mr. Johnson,how hasknowledge management changed the way your company works?M: In lots of ways. The most significant change occurs in how we manage the process of ourproject development …Q: What is the woman probably doing?Conversation 3W: Recently, reality television has swept across almost all channels: matchmaking, job hunting,and talent shows. I don’t know why people are so crazy about it!M: In my view, some people watch reality TV because it makes them feel they’re better thanothers. They may also enjoy seeing other people get embarrassed.Q: What does the man say about reality TV?Conversation 4W: I think teenagers today experience a different social reality from what we had before.M: Exactly. When we were kids, we would hang out with friends, chatting, or going to movies.That’s our experience, but what we see now is that young people are choosing to live online.Q: How do young people socialize today according to the man?Conversation 5W: Much has been said about how anti-social the Internet and mobile phones are, butI think communications technology is bringing people closer.M: Yes, I’d go along with you on that. With these modern tools, there’s a new kind of connectionbeing built within families.Q: What does the man think of modern communications technology?Long conversationW: Hey Billy! It’s 7:30 p.m.! Turn off your TV and computer. Come down to dinner. It seems yourfather is finishing his conference call with his team in China.M: OK Mom. Coming. But why is Dad on his computer while I can’t be on mine! W: Billy, your father is working. But you are chatting with your friends aboutcelebrities!So your father needs to be on his computer. And you don’t!M: OK. Sorry, Mom. What are we having for dinner? Pizza?W: Pizza?! I’ve made us a nice dinner of roast chicken, mushroom soup and vegetable salad. Ieven made chocolate cake for dessert –and you want pizza!M: Just kidding Mom! I love your cooking! Mmm I’m hungry, and it smells delicious!W: Billy! I told you to shut down all electronics!M: Mom! This isn’t fair. You told me to turn off my computer and my TV –you didn’t say allelectronics –and you didn’t mention my cell phone! I have to check the news! My favoritegolf player just got in trouble for drunk driving! Please Mom! I have to find out! W: You can’t go five minutes without having your eyes on a screen! Hand me your phone. Now! Iam turning it off so we can have a nice dinner.M: OK Mom. Fine! Here’s my phone.W: Now, where is your father?M: Will you make Dad do the same? We never have family dinner anymore without Dad being onelectronics!。

M:你看了昨晚电视节目《关于藤壶的粘合特性》吗？
W:不，我错过了。
你对他们有什么了解？
M：它们在出生后不久就粘在海洋中的岩石上。
他们也呆在同一个地方。
你曾经试过去掉其中的一件东西吗？把岩石炸开比把藤壶关起来容易些。
男：没错！这就是为什么科学家们试图弄清藤壶的胶水是什么，它被认为是自然界中最强的粘合剂之一。
W:它的优点是能够在潮湿的表面上工作。
M：正是如此。
因为它是一种天然蛋白质，它可能不会对像现在使用的许多合成胶黏剂一样有害的人：想想医生和牙医可以用这种方法修补骨头，固定假牙M：有无数的用途。
科学家希望能很快了解胶水是什么制成的，这样人们就可以利用它。

随着价格和建筑成本的不断上升，“自食其力”（DIY）趋势持续增长，我们需要为我们的客厅准备家具，“约翰·罗斯说，”我们只是没有足够的GH钱购买它。
所以我们决定试着做几张桌椅。
约翰六个月前结婚了，现在和许多年轻人一样，他们正努力在生活费用很高的时候回家。
Rosses在一所夜校上了280美元的为期两周的课程。
现在他们把所有的家具都修好了，修理房子周围的Jim Hatfield有三个男孩，他的妻子死了。
他在家里有一份全职工作，还有一家制鞋厂。
上个月，他收到了S420的一张汽车修理单，“我对此很苦恼。
现在我已经完成了一个汽车修理课程，我应该能自己修车。
约翰和吉姆并不是不寻常的人。
美国的大
多数家庭都在尽其所能来省钱，这样他们就可以与高昂的生活费用抗争。
如果你想成为一个“自己动手”的人，你可以去上DIY课程。
对于那些没有时间参加课程的人来说，有一些书告诉你，你可以自己做事情。
我们中的一些人花了高中的时间去解剖青蛙，在偶尔的舞蹈中感到尴尬，但是西班牙的一小部分学生在教育时间方面做得更酷了：他们把数码相机送到了太空，一个老师和四个来自Catal莱斯拉比巴斯学校的学生。
西班牙航空公司购买了一个价值60美元的气球，并安装了一个80美元的数码相机，然后把它送上天空，拍摄一些高空照片。
这个小组只想看看他们是否能让他们自制的气象气球飞到大多数商用飞机飞行的高度。
但是到了30000英尺，气球一直爬升到离地球20英里远的地方，在太空的边缘。
利用气象传感器和谷歌地球追踪气球的进展，团队追踪了大气状况，并捕捉了一些令人惊奇的照片。
四名学生和他们的老师在2009年2月完成了实验。
该小组自己建造了电子传感器部件，然后将它们连同摄像机一起放进一个保护性的外壳中，然后将钻机释放到天空中，气球上升到100英尺以上的高度，然后掉落地面。
该团队飞行超过10公里寻找气球和设备。
他们惊奇地发现，尽管暴露在极端恶劣的环境中，设备仍在发出信号。
尽管存在争议，直接面向消费者的基因检测正变得越来越流行。
这种基因测试更像是自己动手做的诊断。
它变得几乎一样容易作为一个家庭怀孕测试。
人们可以使用他们的信用卡在网上订购一套工具，用刷子去除一些脸颊细胞，返回工具并通过电子邮件接收报告。
DTC测试成本从几百美元到几千美元，可用于从乳腺到癌症的超过800个条件。

人口可能是特别准备DTC测试，因为它有一个自己动手的伦理，习惯于支付口袋里的医疗服务。
提供基因测试的公司热衷于广泛的DTC测试的前景。
他们认为基因测试与非DNA测试没有什么不同。
但并不是每个人都为消费者能够接受基因测试而感到兴奋。
有些人担心DTC基因检测对公众构成危险。
患者可能会经历心理伤害，因为他们可能不理解结果意味着什么，那么在互联网上缺乏监管也可能导致这样一个事实，即网络给你的信息可能是非常误导和潜在的危害你。
然而，只要医生能帮助他们，许多人对缺乏监管感到满意。
那么DTC基因测试的未来是什么呢？我们不能指望在未来几年里对基因疾病进行广泛的自我筛查。
但我们可以预测某些疾病的DTC基因检测的增长，并完全期待这种技术将与我们同在。
