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（過濾器）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.

Love to sink into your chairs and relax when you get to school? Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all — Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty? Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched (牽強的), the officials at the few schools around the world seem to agree.

Among them are educators from the College Station Independent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided with a device that helped record step count and calorie consumption over the entire period.

All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to “sit still”, older kids have a harder time adjusting to this unexpected freedom.

American schools are not the only ones reporting success with stand-up desks. Four Catholic schools in Perth, Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in Bradford, West Yorkshire, became Europe’s first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging.

The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers — it helps kids get healthier and provides educators with a more engaged audience.

1.According to the teachers, older students may not like stand-up desks because ____________.

A. they are cleverer than younger students

B. they are easily tired of standing long

C. they have formed the habit of sitting

D. they do badly in class while standing

2.What is most likely to be the result of the seven-week trial?

A. The standing desks can’t be used at all.

B. It is good for students to use stand-up desks.

C. More tests should be done in other schools.

D. The students are different in personality.

3.Why do the teachers like the standing desks?

A. Because the educators can draw the students’ attention.

B. Because the teachers can keep the students healthy.

C. Because the students can have a walk in the classroom..

D. Because the standing desks can keep the students concentrated.

An interesting study posted on Facebook recently shows how men and women develop new interests as they mature(成熟).

While women tend to take exercise seriously from the age of 34, men will wait until their 45th birthdays before working hard to get in shape.

The average woman spends more time talking about sports, politics, career and money as she gets older.

Women’s interest in books reaches its peak(頂峰) at the age of 22, while that of men does so when they are in their 50s.

Men start to change their focus from the workplace to other things after age 30, while women do not do so until eight years later. Both, however, care most about fashion at age 16.

The research used anonymous(匿名的) data donated by thousands of Facebook users, recording the statuses, ‘likes’ and ‘interests’ they had posted on their profiles.

It found the average woman talks about television most at 44, while men peak much younger, at age 31.

Men are also most likely to see a film in a cinema at age 31, while women go out to see films most when they are only 19.

Men are most interested in travel at 29, women at 27, while women talk most about food and drink at 35, and men at 38.

And if you are middle aged, a safe topic for any audience is the weather, which is a key interest for many as they approach 60.

Stephen Wolfram, the British scientist who carried out the research, says, “It’s almost shocking how much this tells us about the changes of people’s typical interests.

“People talk less about video games as they get older, and more about politics.”

1. When do women love books best?

A. At the age of 22. B. At the age of 50.

C. At the age of 30. D. At the age of 15.

2.Men tend to ______ once they are 30.

A. gain more and more weight

B. be less interested in their jobs

C. do more exercise

D. pay more attention to their appearance

3. What are men and women both interested in when they are 16?

A. Getting in shape.

B. Going to the cinema.

C. Popular style of clothing.

D. Food and drink.

4.What does Stephen Wolfram think about the result of the research?

A. People’s interests are different from each other.

B. People’s interests change greatly with age.

C. It is normal for people to change their interests.

D. It is not good for people to change their interests.

Good news! Job offered.

Have you ever been sad because of failure? Please remember, for quite often achieving what you set out do is not the most important thing.

A boy decided to dig a deep hole behind his house. As he was working, a couple of older boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that digging a hole all the way through the earth was impossible. After a while, the boy picked up a jar. He showed it to the visitors. It was full of all kinds of stones and insects. Then he said calmly and confidently, “Maybe I can’t finish digging all the way through the earth, but look at what I’ve found during this period!”

The boy’s goal was far too difficult, but it did cause him to go on. And that is what a goal is for－to cause us to move in the direction we have chosen, in other words, to cause us to keep working!

Not every goal will be fully achieved. Not every job will end up with a success. Not every dream will come true. But when you fall short of your aim, maybe you can say, “Yes, but look at what I’ve found along the way! There are so many wonderful things having come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really makes sense.

1.The older boys laughed at the boy because he was thought to be______.

A. braveB. impolite

C. foolishD. warm-hearted

2. Why did the boy show the jar to the older boys?

A. To drive them away.

C. To show how beautiful the jar was.

D. To attract them to join him in the work.

3.What can be learnt from the fourth paragraph of the text?

A. No dream can come true.

B. All work will end successfully.

C. Goals shouldn’t be set too high.

D. Goals will make us work harder.

4.The best title for the text should be______.

A. A Boy Dug a Hole

B. Joy in the Journey

C. No Pain, No Gains

D. Failure Is the Mother of Success
