In many stories on TV and in science-fiction books, men travel to faraway stars. They have quick, easy journeys. But so far, men have been able to reach only the earth’s own moon.

Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to move faster than the speed of the light. Nothing can move that fast except light itself.

Strange things happen to an object when it moves rapidly. The object weighs more. An object moving at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A clock runs more slowly. A man would not age so fast as he would on the earth.

Light travels more than 186,000 miles a second, or about 11 million miles a minute. In one year, light travels six trillion miles. That great distance is called a light-year. It is used to measure distance in space.

The star closest to our sun is Alpha Centauri. It is more than four light-years away. If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星) in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years

1.In this passage the words “closest to our sun” means the star().

A、the earth we live on

B、Alpha Centauri

C、the Big Dipper

D、the moon

2.A one-way journey to Alcaid would take().

A、about nine years

B、less than four years

C、almost 200 years

D、less than 100 years

3.Why do we measure the distance in light-years instead of miles?()

A、Units of light-years sound better.

B、Using light- years reduced the number of figures used.

C、We used to measure distance in light-years long ago.

D、We do not make mistakes when we use light-years.

4.If a stone moved at the speed of light, it().

A、would weigh twice more than it is motionless

B、would weigh as much as it is on earth

C、would weigh less than it is on earth

D、would not have weight at all

5.This story is mainly about ().

A、the distance between the sun and the other stars

B、the problems of traveling to faraway stars

C、what happens when we travel faster than the speed of light

D、the tool we use when we go to faraway stars

Were you constantly bored as a child? Maybe that helped you to develop your ability to be creative.
Boredom can be a good thing for children, according to Dr Teresa Belton, researcher at the University of East Anglia ’s School of Education and Lifelong Learning. After interviewing authors, artists and scientists in Britain, she’s reached the conclusion that cultural expectations that children should be constantly active could block the development of their imagination.
British actress and writer Meera Syal grew up in a small mining village with few distractions. The researcher said:“Lack of things to do urged her to talk to people she wouldn’t otherwise have engaged with and try activities she wouldn ’ under other circumstances, have experienced, such as talking to elderly neighbors and learning to bake cakes.”
Belton added: “Boredom made her write. Meera Syal kept a diary from a young age, filling it with observations, short stories, poems. ”
The researcher didn’t ignore the old saying the devil finds work for idle hands, though. Belton pointed out that young people who don ’t have the interior resources to deal with boredom creatively may end up smashing up bus shelters or taking cars out for a joyride.
How about watching TV and videos on the computer? The researcher believes that nothing replaces standing and staring at things and observing your surroundings.
It’s the sort of thing thatstimulates the imagination, she said, while the screen “tends to short circuit that process and the development of creative capacity. ” Dr Belton concluded: “For the sake of creativity, perhaps we need to slow down and stay offline from time to time. ”
11. Dr Teresa Belton did her research by_____ .
A.studying cultural differences
B.interviewing professionals
C.keeping a diary
D.observing the surroundings
The expression “the devil finds work for idle hands ” probably means that people are more likely to ?A.do what they should not do if they meet devils
B.achieve nothing if they work with devils
C.do more work if they didn ’t work hard when they were young
D.get involved in trouble if they have nothing to do with their time
Which of the following is the best title for the passage?A.Deal with boredom wisely
B.Learn from a young age
C.Enjoy village life
D.Forget old sayings
What is Dr Belton ’s advice for youngsters ?A.Observe the world around them
B.Get information online from time to time
C.Remain constantly active
D.Read as many books as possible
Which of the following best describes the village where Meera Syal grew up?A.Modern and open
B.Tiny and unexciting
C.Poor and underdevelopment
D.Remote and violent

Newspapers, along with reporting the news, educate, entertain, and give opinions. An important way of reading a large, big-city newspaper is to put it into different sections. Can you find these separate sections: world news, national and local news, sports, business, entertainment, opinions, ads? Does your paper have other sections?
News stories give facts, not the reporter's opinions. Some newspaper editorials (社论) come out with the writer's name, but many newspapers only carry editorials without putting the writers' names on.
You can be a better reader if you know what to expect in a newspaper. For example, you can expect headlines to leave out unnecessary words. You can expect to find the most important facts in the leading paragraph (the first paragraph) of a news story. You can expect important news items to be on the front page. You can expect less important items to be on the inside pages.
Most of all, the more you know about news of the present time, the more you will understand what is in the newspaper; important stories are generally presented one day and followed up on following days. So, an important way to read newspapers is reading one frequently.
1)、A good way to read a newspaper is to find separate sections and read according to your needs.
A.T
B.F
2)、To design ads might NOT be a newspaper reporter's work.
A.T
B.F
3)、From the text we know that newspaper headlines are what readers expect to read.
A.T
B.F
4)、If you are reading for major facts in the news stories, you should read the front page.
A.T
B.F
5)、The writer's suggestion to us is that we should read one newspaper frequently.

第4题
In the United States many have been told that anyone can become rich and successful if he works hard and has some good luck.

Yet, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about. It is the story of someone who tries to look as rich and as successful as his neighbors.

The expression was first used in 1913 by a young American by the name of Arthur Momand. He told this story about himself: he began earning $125 a week at the age of 23. That was a lot of money in those days. Young Momand was very proud of his riches. He got married and moved with his wife to a very wealthy neighborhood outside New York City. But just moving there was not enough. When he saw that rich people rode horses, Momand went horse riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.

It was like a race, but one could never finish this race because one was always trying to keep up. Momand and his wife could not do that.

The race ended for them when they could no longer pay for their new way of life. They left their wealthy neighborhood and moved back to an apartment in New York City.

Momand looked around him and noticed that many people do things just to keep up with their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “keeping up with the Joneses”, because “Jones” is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.

Every city has an area where people want to live because others will think better of them if they do. And there are “Joneses” in every city of the world. But one must get tired of trying to keep up with the Joneses, because no matter what one does, Mr. Jones always seems to be ahead.

6. The writer of the selection believes().

A. many people in the United States think anyone can become rich if he works hard and has some good luck

B. anyone in the United Sates can become rich if he works hard and has some good luck

C. he can become rich in the future

A. they want to be as rich as their neighbors

B. they want others to know or to think that they are rich

C. they don’t want others to know they are rich

D. they want to be happy

8. It can be inferred from the story that rich people().

A. like to live in apartments

B. like to live in New York City

C. like to live outside New York City

D. like to have many neighbors

9. Arthur Momand used the name “Jones” in his series of short stories because Jones is().

A,. an important name

Questions are based on the following passage.He was a qualified doctor who rarely practice
Questions are based on the following passage.
He was a qualified doctor who rarely practiced but instead devoted his life to writing.He once said: "Medicine is my lawful wife, and literature is my lover." Russian writer Anton Pavlovich Chekhov was a great playwright and one of the masters of the modem short story.
(77) When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family. After he graduated, he wrote regularly for a local daily newspaper.
As a writer he was extremely fast, often producing a short story in an hour or less. Chekhov&39;s medical and science experience can be seen through the indifference(冷漠) many of his characters show to tragic events. In 1892, he became a full time writer and published some of his most memorable stories.
Chekhov often wrote about the sufferings of life in small town Russia. Tragic events control his characters who are filled with feelings of hopelessness and despair.
It is often said that nothing happens in Chekhov&39;s stories and plays. He made up for this with his exciting technique for developing drama within his characters. (78) Chekhov&39;s work combined the calm attitude of a scientist and doctor with the sensitivity(敏感)of an artist.
Some of Chekhov&39;s works were translated into Chinese as early as the 1940s. One of his famous stories, The Man in a Shell (装在套子里的人), about a school teacher&39;s extraordinarily orderly life, was selected as a text for Chinese senior students.

When I begin to look back on all friends whom I have had, I quickly came to the conclusion that Jerry was the most important and had the greatest effect upon my life. His family moved to my block when I was only 10. Jerry was 15 at the time, but the fact that he was so much older than me seemed to make no difference to him. I was very glad that he liked me. We took long walks together, on which he would tell me stories he had heard form. TV and radio programs.
But as months went by, a change came into our friendship. Jerry almost stopped coming by the house, and every time I went to his house or telephoned, he put me off with some excuses such as "I'm studying now" or "I've got some jobs to do for Mum". When we passed on the street, he would still give me a warm smile and friendly wave with a "Hi, kid", but he would hardly ever stop to talk. Finally I realized that he was no longer interested in me and that his,taste had changed. I noticed him with a girl once in a while and several times saw him going out in his family's car on a Friday or Saturday night. I simply couldn't understand what was so great about girls and parties.
But I was hurt when he finally made me know that our friendship was at an end. Of course he didn't really mean to hurt me, but it was a long time before I realized that it was an age problem that caused the break. There were a world of differences between the ideas and interests of a 17-year-old and a 12-year-old. Now that I'm over sixteen myself, I realized this, and the hurt I got then has become happy memories of the good times we were once together. I wonder if millions of other boys and girls have had a similar experience.

(3)、Jerry stopped playing with the writer because ______.

(4)、When a change came in their friendship, the writer ______.
A:accepted it at once
B:couldn't understand his friend for a long time

D:started going to parties with girls

第8题
Sleep is a funny thing. We're taught that we should get seven or eight hours a night, but a lot of us get by just fine on less, and some of us actually sleep too much. A study out of the University of Buffalo reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke--probably as a result of an underlying disorder that keeps them from sleeping soundly.
Doctors have their own special sleep problems. Residents are famously short of sleep. It is not unusual for. them to work 40 hours in a row without rest. They are not in the least worried about it, confident they can still deliver the highest quality of medical care. But an article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person' s motor performance is comparable to that of someone who is drunk. Curiously, surgeons who believe that operating under the influence of alcohol is grounds for sacking often don' t think twice about operating without enough sleep.
"I could tell you horror stories," says Jaya Agrawal, president of the American Medical Student Association, which runs a website for residents. Some are terrifying." I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly planted my face into the wound."
"Practically every surgical resident I know has fallen asleep at the wheel driving home from work," writes another. "I know of three who have hit parked cars. Another hit a 'Jersey gate' on the New Jersey Expressway, going 105kin/h."
"Your own patients have become the enemy," writes a third, because they are "the one thing that stands between you and a few hours of sleep."
The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worded about the people treating you or a loved one, you should feel free to ask how many hours of sleep they have had and if more rested staffers are available.
Sleep is a funny thing because ______.
A.the longer one sleeps, the less sound sleep he gets
B.the more sleep one gets, the more likely a stroke occurs
C.many people stick to about eight hours of sleep to stay fine
D.many people who sleep six hours a night still feel energetic in the day
