Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment . “We didn’t know at that time that there even was an environment, let alone that there was a problem with it, ”says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement . Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times, ”says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.

According to US government reports , emissions (排放) from cars and trucks have dropped from 10. 3 million tons a year to 5. 5 tons . The number of cities producing CO beyond the standard has been reduced from 40 to 9 . Although serious problems still remain and need to be dealt with , the world is a safer and healthier place . A kind of “Green thinking ” has become part of practices .

Great improvement has been achieved . In 1988 there were only 600 recycling programs , today in 1995 there are about 6, 600 . Advanced lights , motors , and building designs have helped save a lot of energy and therefore prevented pollution .

Twenty –five years ago , there were hardly any education programs for environment . Today , it’s hard to find a public school , university , or law school that does not have such a kind of program . ” Until we do that , nothing else will change! ” say Bruce Anderson .

Tomorrow's World Book Day has inspired a slew of literary events throughout the capital. Xing Yi and Liu Zhihua report.

As World Book Day, April 23, approaches, various reading events are being held by government agencies, libraries and bookstores throughout the capital.

At the launch of the 5th Beijing Reading Season in Great Canal Park in Tongzhou district on Saturday night, 81-year-old Yin Zhiguang, head of Beijing Elocution Troupe, led the audience in reciting a poem.

Activities focusing on different readerships will highlight World Book Day in bookstores throughout Beijing, such as picture book sharing for children in Xidan Book Building, conversations with musicians and authors for young people in Sanlian Bookstore, talks with diplomats for people interested in international affairs in Wangfujing Xinhua bookstore, and a 12-hour late-night reading marathon for night owls at One-Way Space bookstore.

Recently, we conducted a survey about how many extra-curricular books students read per year. On average, each student read 5.34 books, which is definitely not adequate compared with their counterparts from the Western countries. It is upsetting to see the outcome. When asked what students in our school do in their spare time, they claim that they tend to watch TV and surf the Internet, for they can have great fun. Some students even complain that they are forced to attend some extra make-up classes so that they have no time to play, not to mention reading books.

School authority is planning to launch a campaign to encourage students to read more extra-curricular books.

The story began with a young mother who had three sons. Unfortunately, the youngest son developed slow thinking skills, not having the intelligence of his brothers.

With double duty as the mother of the household, she was exhausted, so that the youngest was often the target of anger and annoyance. Bad words, such as “you little fool” and the like, served as a daily meal for the youngest.

The words and curses he got from the mother and ridicule from friends convinced him that he was distressing and embarrassing his family. Every morning he woke up with his own face staring from the mirror reflection, he started to say quietly and sadly, “The fool is going to school.”

Pango was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.

Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.

This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.

The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.

The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (殺蟲劑）and medicines. Soon there was no money left.

Then the people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job—eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.

Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.

1.From Paragraph 1 we learn that the villagers ________.

A. worked very hard for centuries

B. dreamed of having a better life

C. were poor but somewhat content

D. lived a different life from their forefathers

2.Why did the villagers agree to sell frogs?

A. The frogs were easy money.

B. They needed money to buy visitors.

C. They wanted to please the visitors.

D. The frogs made too much noise.

3.What might be the cause of the children’s sickness?

A. The crops didn’t do well.

B. There were too many insects.

C. The visitors brought in diseases.

D. The pesticides were overused.

4.What can we infer from the last sentence of the text?

A. Happiness comes from peaceful life in the country.

B. Health is more important than money.

C. The harmony between man and nature is important.

D. Good old days will never be forgotten.

In my first week as a graduate student at Cambridge University in 1964 I met with a fellow student, two years ahead of me in his studies; he was unsteady on his feet and spoke with great difficulty．This was Stephen Hawking．I learned that he had a bad disease and might not live long enough even to finish his PhD degree．

But, amazingly, he has reached the age of 73．Even mere survival would have been a medical miracle, but of course, he didn’t merely survive．He has become arguably the most famous scientist in the world for his brilliant research, for his bestselling books, and, above all, for his astonishing victory over hardship．

Stephen received his “death sentence” in 1964, when I thought it was hard for him to go on with his study．Stephen went from Albans School to Oxford University．He was said to be a “l(fā)azy” undergraduate, but his brilliance earned him a first class degree, an “entry ticket” to a research career in Cambridge and a uniquely inspiring achievement．Within a few years of the burst of his disease he was wheelchair bound, and his speech was so unclear that it could only be understood by those who knew him well．But his scientific career went from strength to strength: he quickly came up with a series of insights into the nature of black holes (then a very new idea) and how the universe began．In 1974 he was elected to the Royal Society at the exceptionally early age of 32．

The great advances in science generally involve discovering a link between phenomena that were previously conceptually unconnected — for instance, Isaac Newton realized that the force making an apple fall to earth was the same as the force that holds the moon and planets in their orbits．Stephen’s revolutionary idea about a link between gravity and quantum(量子) theory has still not been tested．However, it has been hugely influential; indeed, one of the main achievements of string theory(弦理論) has been to confirm and build on his idea．He has undoubtedly done more than anyone else since Einstein to improve our knowledge of gravity and he is one of the top ten living theoretical physicists．

1.What impressed the author most about Stephen Hawking?

A．His brilliant research．

B．His bestselling books．

C．His serious disease．

D．His defeating hardship．

2.What made Stephen Hawking start his research career at Cambridge?

A．His death sentence．

B．His “l(fā)azy” attitude．

C．His above average talent and ability．

D．His rich experience．

3.It can be inferred that Stephen Hawking was born ________．

A．in the early 1940s

B．in the late 1940s

C．in the early 1930s

D．in the late 1930s

4.What can we learn from the text?

A．Hawking’s theory was proved years ago．

B．Hawking was not as successful as Newton．

C．String theory built on Hawking’s idea．

D．Hawking’s theory has had little influence on others．

5.Which of the following is Not True according the passage?

A．He achieved one success after another in his career despite his disease．

B．He couldn’t walk when the author first met him at Cambridge．

C．He not only survived his disease but contributed greatly to science．

D．He is among the greatest scientists to improve the knowledge of gravity．
