When you look at a book, it sends your eyes some of the light that falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if it took no time at all. Light reaches us form the moon , which is about 380,000 kilometers away, in only a little more than a second.

But there are other stars, other suns. Not only thousands of them, but millions of them. Do different stars have planets? We can see the planets round our own sun. But we haven’t seen any more. The stars are too far away from us. Stars give out (发出)light, but the planets don’t have any light of their own. So we can’t see them. They’re too far, and too dark.
Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this, Then we know that the star has a planet.
For example, Barnard’s Star(巴纳德星)is a small red star. And it is the quickest star in the universe. But sometimes it moves slower, and then quicker again. We have know Barnard’s Star for many years, and now we are sure it has a planet.

From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
小题1:Which of the following should not be used when trying to escape from a fire?
A.Windows | B.Elevators | C.Fire exits | D.Stairways |
A.about 12 feet | B.about 6 feet |
C.about the height of an average man | D.nearly 10 feet |
A.the only way | B.the best way |
C.safer than any other ways | D.one of the possible ways |
A.breathing in smoke might be harmful | B.smoke will enter the room through an open window |
C.fresh air can’t reach the second floor window | |
D.to keep you head low will help you to escape a fire |
A.drop directly onto the ground | B.first drop onto a roof then onto the cement |
C.drop from a roof window then onto bushes and trees | |
D.drop onto the cement rather than bushes and grass |
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must keep careful of the rise in pollution at the same time.
小题1:Our world is becoming much smaller ___________.
A.because the earth is being polluted day and night. |
B.thanks to science developing. |
C.because of the rise in pollution |
D.because the earth is blown away by the wind every year. |
A.water pollution | B.air pollution | C.noise pollution | D.rubbish |
A.it’s bad to all living things in the world. |
B.it makes us become angry more easily. |
C.it has made our rivers and lakes dirty. |
D.it makes much noise. |
A.The problem of pollution is not so serious because there are not so many people. |
B.From now on, maybe people try to go to work by bus or bike instead of car or motorbike. It is helpful to fight against the pollution of SO2. |
C.The pollution of the earth grows as fast as the world’s pollution does. |
D.Many countries are making rules to fight pollution. |
If Dick had listened to his boss in 1925, we might not have a product that we now think of as of great importance: a new type of tape. Dick worked for the Minnesota Mining Company. At work he developed a kind of material strong enough to hold things together. But his boss told him not to think more about the idea. Finally, using his own time, Dick improved the tape, which now is used everywhere by many people. And his former company learned from its mistake. Now it encourages people to spend 15 percent of their work time just thinking about and developing new ideas.
Creativity is not something one is just born with, nor is it necessarily a character of high intelligence. The fact that a person is highly intelligent does not mean that he uses it creatively. Creativity is the matter of using the resources one has to produce new ideas that are good for something.
Unfortunately, schools have not tried to encourage creativity. With strong attention to test results and the development of reading, writing and mathematical skills, many educators give up creativity for correct answers. The result is that children can give back information but can’t recognize ways to use it in new situation. They may know the rules correctly but they are unable to use them to Work out practical problems.
It is important to give children choices. From the earlier age, children should be allowed to make decisions and understand their results. Even if it’s choosing between two food items for lunch, decision-making helps thinking skills. As children grow older, parents should let their children decide how to use their time or spend their money. This is because the most important character of creative people is a very strong desire to find a way out of trouble.
小题1:What did the company where Dick once worked learn from its mistake?
A.They encouraged people to work a longer time. |
B.They discouraged people to think freely. |
C.They asked people to spend all their work time developing new ideas. |
D.They encouraged people to spend some of their work time considering and improving new ideas. |
A.that people are born with |
B.that depends on intelligence |
C.that is a way of using what one has learnt to work out new problems |
D.that is not important at all |
A.They don’t understand the importance of education. |
B.They don’t want their students to make mistakes. |
C.They pay too much attention to exam marks, language and mathematical skills. |
D.They think it more important to remember some information. |
A.Try to help them as much as possible. | B.Take no notice of whatever they do. |
C.Leave them as they are. | D.Help them if their decision is wrong, but not too much.. |
This childhood intention is described in her novel, A Sound of Chariots, which although written in the third person is clearly autobiographical (自传体的)and gives a picture both of Mollie’s ambition and her struggle towards its achievement. Thoughts of her childhood inevitably(不可避免的)brought thoughts of the time when her home was still a village with buttercup meadows and strawberry fields-sadly now covered with modern houses. “I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood. I’ll never go back,”she said.“Never.”“When I set one of my books in Scotland,”she said,“I can recall my romantic feelings as a child playing in those fields, or watching the village blacksmith at work. And that’s important, because children now know so much so early that romance can’t exist for them, as it did for us.”
小题1: What does Mollie Hunter feel about the nature of a good book?
A.It should not aim at a narrow audience. |
B.It should be attractive to young readers. |
C.It should be based on original ideas. |
D.It should not include too much conversation. |
A.Being poor in life experience |
B.Being short of writing skill. |
C.The weakness of description |
D.The absence of a story. |
A.She didn’t expect to become a writer. |
B.She didn’t enjoy writing stories. |
C.She didn’t have any particular ambition. |
D.She didn’t respect her teacher’s view. |
A.more intelligent |
B.better informed |
C.less eager to learn |
