The expression “a thirst for knowledge" may soon have a new meaning for millions of people who have no way to get clean water. Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world.
About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria.
The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles (微粒) of silver. The pages can be used as filters（过滤器）to remove harmful microorganisms (微生物) that can pollute drinking water. The filter kills the organisms that pass through it.
Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned.
Ms. Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages.
"The idea of classic texts—that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through that part," she says.
Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful.
Water for Life, a non-governmental organization, has provided financial support for the project.
1.What do we learn about the book from the text?
A. It sells well around the world.
B. It has pages with several functions.
C. It is about environment protection.
D. It can treat about 100 liters of water.
2.What does the underlined phrase "that part" in Paragraph 6 refer to?
A. Classic texts. B. Invention presentation.
C. Exciting discussion. D. Financial support.
3.In which country did not the researchers test the drinkable book?
A. Bangladesh. B. Ghana
C. South Africa. D. America.
4.What is the main idea of the passage?
A. Researchers have found a way to save those being ill.
B. Millions of people are in great need of drinkable water.
C. Book pages could provide safe drinking water.
D. Knowledge is as important as drinkable water.

It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other part.
The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
1.The first paragraph tells us that _____.
A. all living things in nature depend on each other
B. everything in nature can’t exist without the help of man
C. man has known the importance of the balance of nature for a long time
D. no living thing can live naturally
2.In the second paragraph the examples given are used to prove that _____.
A. all forms of life belong to a system in which all the parts can be changed for one another
B. it is only during the last few years that man has generally known the balance of nature
C. there are some living things which can exist by themselves without change
D. we can’t change one form of life without destroying the balance of nature
3.The last paragraph suggests that in order to get his immediate benefits(利益) _____.
A. man is always anxious to control his activities within limits
B. man is always too eager in planning for distant future
C. man often fails to think about their future results of his action
D. man often feels that he will have to give up in despair
4.Which of the following is true according to the passage?
A. Cutting down woods does little harm to human beings.
B. Man has to pay much more attention to the future results of his present action.
C. Oxygen comes from forests.
D. The passage tells us to try our best to get as much as possible immediately.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
●Does failure really exist?
If you believe you have failed, then you have. If you believe you don’t have the ability to succeed, then you don’t. 1. The moment you decide to give up or stop working toward your goals, failure is born.
● 2.
Most people give themselves an out without even realizing it. They are willing to work hard on reaching their goals, but only until the going gets too rough or their energy dies down. Don’t do that! 3. Never quit, never admit failure, and never lose heart.
●Don’t believe in a clear finish line for goals.
It’s a good idea to set a general timeline, but remember that something will be beyond your control. 4. If you lock yourself into a given timeline, you might make yourself feel like a failure! Instead, get a general idea of when you’d like your goal to be completed. Then take it one day at a time and focus on making progress instead of reaching the finish line in as little time as possible.
●Be sure that you don’t see difficulties as failures.
Difficulties mean only one thing: it’s not time for your goal to be completed yet. That’s it! It doesn’t mean you failed; it doesn’t mean you’re weak; it doesn’t mean you’ll never achieve your goals. 5. You’ve got to keep moving forward and find a way over, around, or through the difficulties.
A. Never give up on yourself.
B. Failure only exists in your own mind!
C. That’s exactly how failure makes us feel.
D. It simply means you have not done enough yet.
E. You can never say exactly when your goal will be reached.
F. Instead, make up your mind to make your goal happen, no matter what!
G. Work hard towards your goal, and you will be likely to get good results.
