As we know, museums are buildings with many precious and important objects(物品) from different places. They are kept so that people can go and see them. For example, art museums are places where people can learn about d1. cultures. More and more popular "design museums" are opening today, h2., play quite a different role. Unlike most art museums, the design museum shows objects that are e3. found in our daily life, such as fridges and washing machines. The a4. of design museums is that they are places where people feel familiar with the exhibits. Being different from the art museum visitors, design museum visitors s5. feel frightened or puzzled. This is partly because design museums clearly show how and why mass-products(批量产品) work and look as they do, and how design has i6.our lives. People can see the better changes of the products. Art museum exhibits, on the o7. hand, would most probably fill visitors with a feeling that there is something they don't understand.

Several new design museums have opened their doors in recent years. Each of these museums has tried to satisfy the public's growing interest in the field with new i8.. London's Design Museum, for e9., shows a collection of mass-produced objects from electric typewriters to a group of Italian fish-tins.

Fishing is a popular activity and every fisherman knows the rule: Keep the big ones, throw the smaller ones back. The idea behind Lt is simple - the larger fish are probably older. If you keep the smaller ones, they won’t be able to reproduce, and the fish population is in danger.

But fishing out the largest fish from a population has an unwanted effect: Over time, fewer adult fish get really big. If only the smaller fish reproduce（繁殖）, then future generations become smaller. This is an example of evolution（进化） in action.

One scientist, Dr David Conover has spent the last decade studying the effects of the “keep the big ones” rule and if they can be reversed（颠倒）.

To set up his experiment, Conover and his team caught hundreds of silverside fish and divided them into six groups. For two groups, Conover followed the “keep the large ones” rule and took out the biggest fish. For two other groups, he removed only the small fish.

For the last two groups, he removed fish at random (随意的).

After five years, he measured the fish in each group. In the two groups where the largest fish were regularly removed, the average fish size was smaller than the average size in the other groups. Here was evolution in action: If only small fish survive to reproduce, then future generations of fish will also tend to be small.

For the second five years of his experiment, Conover changed the rules and took fish randomly from each group. At the end of the experiment, he found that the fish that were in the “keep the large ones” group for the first five years had started to get larger again, although he calculated it would take at least 12 years for the fish in that group to return to their original size.

In other words, it takes less time to shrink(变小) than it does to recover.

1. The underlined word “it” (Line 2) refers to “　　　　　　　 ”

A. the activity        B. the fish

C. the rule            D. the fisherman

2.Why do many people follow the “keep the big ones, throw the small ones back” rule?

A. It helps to protect fish numbers.

B. It helps to protect fish size.

C. It is the custom in most countries.

D. They will be punished if they don’t.

3.What did Conover find after the first five years of his experiment?

A. The “keep the big ones” rule made no difference to fish size.

B. The “keep the big ones” rule made fish smaller on average.

C. The “keep the big ones” rule made the fish bigger on average.

D. The “keep the big ones” rule affected all fish populations in the same way.

4. What is the author’s intention in writing this article?

A. To encourage people to fish more carefully.

B. To urge governments to change the rules of fishing.

C. To describe the results of a scientific experiment.

D. To introduce the rules of fishing to readers.

You can’t see any object unless light from that object gets into your eyes．Some of the things you see give off light of their own。The sun，the stars，a lighted lamp are the examples that can be seen by their own light．But most of the things you see are not giving off light of their own．They are just reflecting(反射)light that falls on them from the sun or some other luminous bodies．The moon，for example，doesn’t give off any light of its own．It is not 1uminous．You see it because sunlight falls on it and some of the sunlight reflects on the earth．So moonlight is only second—hand sunlight．

When you look at a book，it sends some of the light which fails on it to your eyes，and you see the book．If light could be kept out from where you’re so that there would be no light from the book to reflect．Then you couldn’t see the book even with your eyes wide open．Light travels so fast that the time in which it travels from the book you’re reading to your eyes is as short as if there were no time at time．Light reaches us from the moon，which is about 380，000 kilometres away，in only a little more than a second．

1.You can see the book because________．

A．your eyes are close to it       B．it reflects some of the light

C．it has light of its own         D．it is big enough to be seen

2.The Chinese meaning of the world“luminous”is close to_______．

A．闪光的       B．看不见的      C．发光的       D．明亮的

3.________has light of its own．

A．The moon   B．The earth   C．The sun    D．The satellite of Dong Fong Hong

4.Light travels about_________kilometers per second．

A．300，000      B．100，000      C．400，000        D．190，000

5.Which of the following is TRUE?

A．All the things you can see give off light．

B．Light from the book is much faster than that from the moon．

C．The moment you open your eyes，the light from the book travels to your eyes．
