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' 11 be disturbed by jet planes, transistor 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.

Move Earth—it’s no science fiction
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams is designed to carefully direct a comet or asteroid（小行星） so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped(剥去) away from Earth,” it states. This would greatly change our planet’s climate.What makes the scientists plan to move Earth?
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
If the plan is successful, Earth will have a working life of ______ years.
| A．12 billion | B．6 billion |
| C．18 billion | D．24 billion |
What serious problems might the plan cause according to the passage?
| A．The comet might hit Earth and man might lose the moon. |
| B．Earth might be moved too far away and man might be frozen to death. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
What does the underlined word “compromise” mean?
| A．provide | B．benefit |
| C．share | D．Endanger |
Carmen Arace Middle School is situated in the town of Bloomfield，but four years ago it faced many of the same challenges as inner—city schools nearby：low scores in standardized tests and dropping enrollment（入学率）of students．Then the hard-driving headmaster, Delore Bolton，persuaded her school to shake up the place by buying a laptop computer for each student and teacher to use in school and at home．For good measure，the board provided wireless Internet access at school．Total cost :$5 million．

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
Not all past predictions have been proven wrong. A few of them have been surprisingly accurate. Some great thinkers predicted the arrival of the credit card, the fax machine and even the internet years before they happened. But for each prediction that has come true, some others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other working environments.Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.So why hasn’t it happened? Maybe because robots are still too expensive and clumsy. And probably the idea of robots cooking our dinners and washing our clothes is just too strange. At home we seem to be doing fine without them.
Telephones of tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet. Why? The technology worked fine, but it overlooked something obvious: people desire for privacy. Would you want to have a video phone conversation with someone after you just stepped out of the shower? Probably not--it could be uncomfortable! Just because technology doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy any more! But a flying car remains one of the most wonderful technology ideas to catch our imagination. Keep watching the news or perhaps the sky outside your window to see what the future will bring..The passage mainly deals with______.
| A．predictions that can catch our imagination |
| B．predictions that haven’t come true |
| C．new technology can benefit our life |
| D．predictions that have come true |
According to the passage, which of the following statements is NOT true?
| A．Technology doesn’t always mean people will want to use it. |
| B．Predictions don’t need to consider people’s practical use of the technology. |
| C．Not all the high-tech things people thought we’d be using by now are widely used |
| D．High-tech things are not always convenient to people’s life. |
Robot Helpers haven’t been used in most people’s homes because______.
| A．using the kind of robots at home is simply a waste of time and money |
| B．the kind of robots hasn’t been developed yet |
| C．people find it difficult to control the kind of robots |
| D．the kind of robots won’t bring people practical use |
How does the writer find the flying car?

| B．It is too crazy an idea to realize. |
| C．It is likely to appear in the future. |
| D．It has been the focus of the news. |
Heroes of Our Time
A good heart
Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship（奖学金） to study medicine — but Coach (教练) John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this good-hearted man: “Mutombo believes that God has given him this chance to do great things.”
Success and kindness
After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children’s videos (录像) in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others — producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: “I believe it’s the most important thing that I have ever done. I believe that children have the right to live in a world that is safe.”
Bravery and courage
A few weeks ago, Wesley Autrey was waiting at a Harlem subway station with his two little girls when he saw a man fall into the path of a train. With seconds to act, Wesley jumped onto the tracks, pulled the man into the space between the rails (铁轨), and held him as the train passed right above their heads. He insists he’s not a hero. He says: “We have got to show each other some love.”What was Mutombo praised for?
A. Being a star in the NBA.
B. Being a student of medicine.
C. His work in the church.
D. His willingness to help the needy.What did the Baby Einstein Company do at its beginning?
| A．Produce safety equipment for children. |
| B．Make videos to help protect children. |
| C．Sell children’s music and artwork. |
| D．Look for missing and exploited children. |
Why was Wesley Autrey praised as a hero?
| A．He helped a man get across the rails. |
| B．He stopped a man from destroying the rails. |
| C．He protected two little girls from getting hurt. |
| D．He saved a person without considering his own safety. |
Dress codes cause us arguments
The first day of school is always a chaotic(混乱的) time. For many students in the US, this year was even more so. It was all due to one extra school policy. They are now required to wear clothes that meet a new standardized dress code(规范).
According to the handbooks of all high schools in Allentown, Pennsylvania, students must wear short or long sleeve polo shirts and khaki(卡其色的) or black pants. Skinny jeans, leggings(紧身裤), and open toe shoes are not allowed.
Allentown schools are not alone. Overall, about 57 percent of American public schools now have a “strict dress code”, up from more than 47 percent a decade earlier, said USA Today.
Some students don’t mind wearing a similar attire(服装) every day. “It takes away the daily fashion show and helps level the playing fields a little bit with the haves and have-nots,” longtime school safety consultant Ken Trump told USA Today.
But others aren’t happy, claiming that uniforms rob students of individuality(个性).
While school uniforms have been a popular topic to discuss recently in the US, however, in the UK there are much fewer questions about them-they are a tradition.
School uniforms in England were first introduced during the reign(统治) of King Henry VIII in the 16th century. They became popular following the Elementary Education Act of 1870. The UK Department of Education’s website states: “The Department strongly encourages schools to have a uniform as it can…contribute to the beliefs of a school and set the correct tone.
The uniform is now a strong part of school culture in the UK. Schools sometimes even have “Mufti”(便服) days on which students can wear their own clothes if they make a small donation(捐赠) to charity.
However, the tradition does not mean that school uniforms are popular there.
Many “children hate them”, according to Aisha on the BBC Newsround website. Ask UK students why they wear a school uniform and their answer will mostly likely be, “because we have to”.We can infer from the first three paragraphs that ________.
| A．there is a strict standardized dress code in most American public schools |
| B．the high schools in Allentown, Pennsylvania have the strictest dress code in the US |
| C．there has been a growing trend of strict dress codes in US high schools in the last decade |
| D．the new standardized dress code in Allentown’s high schools was put forward by teachers and parents |
We can learn from the article that students’ attitudes towards dress codes are _____
| A．negative | B．divided |
| C．supportive | D．doubtful |
What does paragraph 7 mainly talk about?
| A．The popularity of school uniforms in the UK. |
| B．The history and tradition of school uniforms in the UK. |
| C．The benefits of promoting school uniforms in the UK. |
| D．The UK Department of Education’s requirements on school uniforms. |
According to the article, on Mufti days, students in some UK schools ______.
| A．are required to make a donation to charity |
| B．can vote to choose their own school uniforms |
| C．can wear their own clothes if they contribute to charity |
| D．are allowed to wear whatever they like for the morning |
