Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn't matter where you live--in the middle of a modern city, or a faraway village--the chances are that you' ll be disturbed by jet planes, radios, oil - powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they' re working.
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much(music, for example) may even help people to concentrate.
1.According to this passage, the noise pollution .
A. has become the worst in the countryside B. has become better in big cities
C. has spread from cities to villages D. has been controlled in modern cities
2.Some people have their hearing harmed .
A. while listening to pop music B. in complete silence
C. when speaking loudly D. while watching TV
3.Scientists have discovered that what prevents people from concentrating on something is .
A. all kinds of noise B. changes in the level of noise
C. background noise D. popular music

We know the famous ones—the Thomas Edisons and the Alexander Graham Bells—but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper (雨刮器)？ Shouldn’t we know who they are?
Joan Mclean thinks so. In fact, McLean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she’s developed a course on the topic. In addition to learning “who” invented “what”, however, McLean also likes her students to learn the answers to the “why” and “how” questions. According to McLean, “When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more willing to give inventing a try.”
Her students agree. One young man with a patent（专利）for an unbreakable umbrella is walking proof of McLean’s statement. “If I had not heard the story of the windshield wiper’s invention,” said Tommy Lee, a senior physics major, “ I never would have dreamed of turning my bad experience during a rainstorm into something so useful.” Lee is now considering to sell his patent to an umbrella producer.
So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn’t be a built-in device(装置) for cleaning the window. Still wondering about this when she returned home to Birminghan, Alabama, Anderson started drafting out solutions. One of her ideas, a lever (操作杆) on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.
Today we benefit from countless inventions and innovations. It’s hard to imagine driving without Garrett A. Morgan’s traffic light. It’s equally impossible to picture a world without Katherine J. Blodgett’s innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?

There is no other five-year –old like him. He has a potato-shaped head , thick eyebrows and a voice that is not easily forgotten. He is not evil, but trouble follows him wherever he goes.
Crayon Shinchan（蜡笔小新）enjoys great popularity in China. He has many fans in Hong Kong , Taiwan and on the mainland. And he is one of the hottest cartoon characters in his home country, Japan.
But, the trouble-maker’s show was ranked the No. 1 most unwanted cartoon program by Japan’s Parents’ Association on April 18.
More than half the parents who took part in the study thought Shinchan was a negative role model for children. They believed his actions and speech were adult in nature and not suitable for kids.
Many parents and education experts in China agree with them. Shinchan, they say, is really offensive. He looks out for pretty ladies on the street; at the bookstore he reads magazines full of sexy women; he pretends to be kidnapped by his teacher when he sees a police car; and he raises his mum’s skirt and shouts out the color of her underpants if she doesn’t buy him what he wants.
“Crayon Shimchan is full of dirty humor. The boy shows some terrible adult mentality(心态),which doesn’t match his age,” said Pang Lijuan, professor of the Education Department at Beijing Normal University. Pang further pointed out that Shinchan destroys the traditional image of a polite, hard-working boy. She fears that some teens may copy his behavior and harm their psychological development. Pang and many others in China think that Shinchan is a cartoon for adults-----not for children.
But some kids disagree. Jiangxin, a senior 2 student in Luhe Middle School in Beijing, became a fan of Shinchan after he first saw the cartoon two years ago. He said it is Shinchan’s humor , courage, and cleverness that makes him and his friends love the little cartoon character . “Shinchan looks at the adults’ world with kid’s eyes. He uncovers the hypocrisy(虚伪) and selfishness in a childish way,” explained Jiang. “We watch it just for fun.” But Jiang also admitted that Shinchan is not good for all ages. “It may not be suitable for primary school kids. They may try to blindly copy him.”
Shinchan’s “father ”, Japan’s popular cartoonist, Yoshito Ushi, never thought Shinchan would cause such a heated discussion. He argued that Shinchan is a childish copy of Japan’s middle-aged men. The boy does everything adults would like, but don’t dare to do. “People can easily forgive him because he’s only five years old,” said Yoshito.
1. Teachers and parents dislikes Crayon Shinchan because ________.
A. he looks very ugly
B. he caused a heated discussion
C. the character was created by an adult cartoonist

2.Many children are crazy about Shinchan mainly because .
A. he looks very funny
B. the cartoon character is suitable for all ages
C. they think he is humorous, clever and brave
D. he is a childish copy of Japan’s middle-aged men
3.The underlined word “offensive” in Paragraph 5 probably means .
A. humorous B. ugly-looking C. funny D. unpleasant
4.What is Yoshito Ushi’s explanation of Shinchan’s behaviour?
A. Shinchan is such a naughty boy that he can’t behave himself.
B. Shinchan is trying to draw people’s attention by doing some offensive things.
C. Shinchan wants to set a role model in a different way.
D. Shinchan’ s behaviour is just a childish copy of Japan’s middle-aged men.

An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.
In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起）the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong kong.
In Chicago, the mayor(市长）appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighbourhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.
The only problem arose in New York ,where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致）can be achieved .Or it may show that New Yorkers rather missed the point ,putting all their energy and passion into the choice of the book rather than discussion about a book itself.
Eventually，as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process, or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
1.What is the purpose of the project launched by Nancy?
A.To invite authors to guide readers. B.To encourage people to read and share.
C.To involve people in community service. D.To promote the friendship between cities.
2.Why was it difficult for New Yorkers to carry out the project?
A.They had little interest in reading. B.They were too busy to read a book.
C.They came from many different backgrounds D.They lacked support from the local government
3.According to the passage, where would the project be more easily carried out?
A.In large communities with little sense of unity B.In large cities where libraries are far from home
C.In medium-sized cities with a diverse population
D.In large towns where agreement can be quickly reached
4.The underlined words “shared a word” in Paragraph 5 probably mean .
A.exchanged ideas with each other B.discussed the meaning of a word
C.gamed life experience D.used the same language
5.According to Nancy, the degree of success of the project is judged by .
A. the careful selection of a proper book B. the growing popularity of the writers
C. the number of people who benefit from reading D. the number of books that each person reads
