Book 4Unit 2Working the landⅠ.阅读理解(2019·吉林实验中学模拟)About 5,000 children die each day due to preventable diseases such as cholera and dysentery(痢疾)，which spread when people use unclean water for drinking or cooking.A lack of water for personal health leads to the spread of totally preventable diseases like trachoma，which has blinded some six million people.Water troubles also trap many lowincome families in a cycle of poverty and poor education and the poorest suffer most from lack of access to water.People who spend much of their time on ill health，caring for sick children，or collecting water at distances averaging 3.75 miles a day don’t have educational and economic opportunities to better their lives.Agriculture is called the lion’s share of freshwater worldwide，using some 70 percent，and industrial uses consume another 22 percent.Water areas have no political borders and nations don’t always work together to share common resources，so water can be a frequent source of international conflict as well.Daybyday demand keeps growing，further needing water sources，from great rivers to groundwater.“We’re going deeper into debt on our groundwater use，” Postel said，“and that has very significant impacts on global water security.The rate of groundwater consumption has doubled since 1960.”Some of Earth’s groundwater is fossil water created when Earth’s climate was far different.Today such water is as limited as petrol.“But we’re pumping much of them out faster than ever，” Postel explained.“Humanity’s growing thirst also causes a major problem about water and our ecosystems.And that also creates a cost to us，to our sons and to our grandsons，not just to nature.”语篇解读这是一篇说明文。

Movies of course need impressive images, so why has Alice in Wonderland only resulted in movies best described as “interesting”?

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 2 Grammar 动名词作主语、宾语
Book 4 Unit 2 Grammar 动名词作主语、宾语定义：动名词是由动词+ing变化而来，它仍保留着动词的某些特征，具有动词的时态和语态的变化，但没有人称和数的变化。
用以表达名词所不能表达的较为复杂的意念。
动名词的名词特征表现在它可在句子中当名词来用，作主语、宾语、表语、定语。
它也可以被副词修饰或者支配宾语。
作用：动名词具有名词的性质，因此在句中可以作主语、表语、宾语、定语等。
动名词的形式：(其否定形式是在v-ing前面加not)1．动名词的一般式所表示的动作通常是一般性动作，即不是明确地发生在过去、现在或将来的动作，或者是表示与谓语动词所表示的动作同时发生的动作。
We are very interested in collecting stamps.我们对集邮很感兴趣。
His coming will be of great help to us . 他来对我们大有帮助。
2．动名词的完成式所表示的动作或状态在谓语动词之前完成或结束。
He regrets not having taken part in the work. 他后悔没有参加这项工作。
We were praised for having finished the work ahead of time.我们因提前完成了这项工作而受到了表扬。
3．动名词的否定式是在v-ing前面加not。
He hated himself for not having work hard. 他悔恨自己没有用功。
He felt sorry for not having done the work well. 他为没有把工作做好感到难过。
4．动名词的被动式：当动名词的逻辑主语是行为承受者时，用被动语态。
如：I like being given harder work. 我喜欢接受难点的工作。
She is proud of being admitted into the university. 她为被大学录取而感到自豪。
