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。

Book 4 Unit 3 Part D 听力原文Section A1. M: I believe romantic love is the most important condition for marriage. 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.

波士顿大学和阿萨诸塞州综合医院的一组研究人员正在共同努力，使血糖自动控制成为现实。
这一切都始于一位父亲，他的儿子是糖尿病患者，这个特别的父亲，达米亚诺也恰巧是一名生物医学工程师，而G。
艾夫斯让他尝试解决儿子面临的挑战。
他的儿子胰脏不能正常工作，所以他没有将胰岛素或胰高血糖素释放到他的系统中来控制血糖。
达米亚诺和他的团队提出了一种系统，该系统使用双胰岛素/胰高血糖素泵，并与一个恒定的血糖监测植入物相连，该植入物与A智能手机可以使糖尿病患者与这种仿生胰腺几乎完全正常的生活。
这一切都始于一位父亲说：“如果。

Dan Wright是树顶建筑商的创始人，自2003创办公司以来，他已经建造了400多座树屋。
怀特公司开着自己的树屋工作室，Bala Sundar和他的妻子Lakshmi为自己建造了一个树屋，“我们想在一个僻静的地方建造一些东西，我们可以来这里放松一下。

60岁的鲍伯奇迹想要为他的孙子建造一个。
Sandy Kiefer是大提琴教官。
她的梦想是建造三座树屋并用它们来做早餐。
安装特殊的树形螺栓是工作中最重要的部分。
随着树的生长，有时你需要移动部分结构或者把它的一部分剪下来，让树屋每年生长。
然后在树梢上升起底座。
它很快就会成为一座大树屋的基础，所以孩子们或大人都可以在树顶上玩耍。
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。
男士：对不起。
你等了很久了吗？W:大约十分钟：你注意到了否。
7路公交车经过了吗？W:不是我站在这里的时候。
我在等待“不”。

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。

U。
S。
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。
