阅读下面短文，从短文后各题所给的四个选项(ABC和D)中，选出最佳选项。
A
The blue tits(山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding.
Among many birds that nest in holes, the male has a light-coloured patch on its plumage(鸟羽) which acts as signal for drawing the female’s attention to a suitable nesting-place. Unlike the blue tit, the redstart(红尾鸲) may be only the male that strikingly coloured and the female is not beautiful.
A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously(先前) checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal(显露) his tail.
If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them.
46. How do the blue tits choose their nest?
A. They choose their nest together.
B. The male chooses their nest.
C. The house-hunter chooses their nest.
D. The female chooses their nest.
47. The writer was lucky to see ________.
A. how the male made his tricks
B. how an interested female played with the male happily
C. what the male displayed and won the female
D. that the male tried his best but failed to attract the female
48. You can spot a pair of redstarts in a Walsh wood ________.
A. at any time B. regularly
C. in April D. occasionally
49. The writer is probably ________.
A. a bird expert B. a bird-hunter
C. a bird raiser D. a scientist
B
Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for(对…负责) the opening of that first mine.
Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.
Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres(纤维).
Scientists do not know why the rock can be separated easily into threads(线), but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.
50. Which title best expresses the main idea of this passage?
A. Asbestos mined in Canada
B. Fireproof matter
C. A “wonder” mineral
D. A new roofing material

A.
Thirty years ago ,Lake Ponkapog was full of life .Many birds and animals lived beside the water, which was full of fish .Now there are few birds ,animals and fish. The lake water is polluted. It is filled with strange plants.　　How did this happen ?First, we must think about how water gets into Lake Ponkapog .When it rains ,water comes into the lake from all around. In the past, there were forests all around Lake Ponkapog, so the rainwater was clean.　　Now there are many homes around the lake .People often use chemicals in their gardens .They use other chemicals inside their houses for cleaning or killing insects(昆虫).There are also many businesses. Businesses use chemicals in their machines or shops .When it rains ,the rainwater picks up all the chemicals from homes and businesses and then carries them into the lake. They pollute the water and kill the animals.　　Boats on the lake are also a problem .Lake Ponkapog is a popular place for motorboats .But oil and gas(汽油) from boats often get into the lake. So more bad chemicals go into the water this way.　　People around the lake love their lake and want to save it. Will it be possible ?A clean lake must have clean rainwater going into it .Clean rainwater is possible only if people are careful about chemicals at home and at work .They must also be more careful about gas and oil and other chemicals on the ground. And they mustn't use motorboats any more on the lake. All these may change people's lives .Only then can Lake Ponkapog be a beautiful clean lake again.61.

Wind is the great maker of waves. There are exceptions, such as the tidal waves sometimes produced by earthquakes under the sea. But the waves most of us know are produced by winds blowing over the sea.
Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough (low point) to crest (high point). It has length－the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests to pass a fixed point. None of these things stays the same－for all depends on the wind, on the depth of the water and many other matters.The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position. And it is fortunate that this is so, for if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible.
If we want to find the speed of a wave, we may use the following way:
Speed＝wavelength×frequency
Here, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.
66. What causes waves?
Earthquakes and nothing else.
Only wind.
Eind causes most waves.
Wind causes some waves.
67. Which of the following is true according to the passage?
A. The water of a wave moves away across the sea.
B. The water of a wave remains almost at the same place.
C. The water of a wave goes with the passing of the wave.
D. The length of a wave means the distance from the top of a wave to the bottom.
68. The speed of wave 1 is 100 cm/s, frequency 10. The frequency of wave 2 is 300, while its speed is twice that of wave 1. Which of the following is right?
A. The wavelength of the two are equal.
B. The wavelength of wave 1 is 10 times longer than that of wave 2.
C. The wavelength of wave 2 is longer than that of wave 1.
The wavelength of wave 1 is longer than that of wave 2.

Disposing（处理）of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dump site. Residents or trash haulers（垃圾拖运者）would transport household rubbish, rotted wood, and old possessions to the site. Periodically（定期的）some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.
Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential（住宅区的）neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.
Awareness（意识）of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.
Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city’s reusable waste.
41. The most suitable title for this passage would be __________.
A. Places for Disposing Waste
B. Waste Pollution Dangers
C. Ways of Getting Rid of Waste
D. Waste Disposal Problem
42. During the 18th century, people disposed their waste in many ways EXCEPT for _______.
A. burying it B. recycling it
C. burning it D. throwing it into rivers
43. What can be inferred from the fourth paragraph?
A. Farm areas accept waste from the city in modern society.
B. There is cheap land to bury waste in modern society.
C. It is difficult to find space to bury waste in modern society.
D. Ways to deal with waste in modern society stay the same.
44. The main purpose of writing this article is to _________.
A. draw people’s attention to waste management
B. warn people of the pollution dangers we are facing
C. call on people to take part in recycling programs
D. tell people a better way to get rid of the waste
B
Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin. Merlin's work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.
　　One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.
　　Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin's grand entrance for a long time!
45. The text is mainly about_________.

　 C. Merlin succeeded beyond expectation.
　 D. Merlin got himself into trouble.

We Americans are wasteful people, not used to saving. Early settlers, our forefathers set us an example of wasting everything, for they thought nature’s resources were so plentiful that none of them ever imagined that natural materials would be used up in time. Within a few years of the first Virginia settlement, for example, pioneers burned down their houses when they were ready to move west. They burned down their houses with only one aim to get the nails(钉子) for future use. No one ever gave a thought to the priceless hardwoods that went up in smoke. As a people we destroy many valuable things that other people save. I noticed this when I was living in Britain. I received a letter from one England’s largest banks. It was enclosed in a used envelope(信封) that had been readdressed to me. Such a practice would be unthinkable in the United States. American banks, even the smallest, always use expensive stationery(信笺）with the names of all twenty - eight vice – presidents lists on side of the page.
49. According to the passage, we know the writer is .
A. a Chinese B. a Japanese C. an Englishman D. an American
50. The writer thought their forefathers .
A. set a good example B. wasted many natural resources
C. knew natural resources would be used up in time
D. made the best use of natural materials
51. The used envelope suggests that .
A. the English look down upon the Americans
B. the English banks are very poor
C. the English try their best to save D. the English like using used envelopes
52. Which of the following statements is wrong?
The writer lives in Britain now.
B. American banks use expensive stationery.
C. Americans are not used to saving.
D. The writer’s forefathers burned down their houses in order
to get the nails.
53. The purpose of the passage is to .

Dear Editor,
In our country, the number of wild animals is becoming smaller and smaller. Some of them are even dying out The dangerous methods we human being has taken are as follows:
We have been cutting the trees to build houses, so the home of animals is intruded and they have to find new places to live. In this process, some of them died in the new environment. The abuse of pesticide has also been endangering the life of wild animals.
In addition, in order to earn money, people have been killing the rare wild animals.
In that we have realized the threat of our behavior to our best friends, we should take actions to change such a condition by taking the following methods:
We should protect the wild animal by protecting the environment that they live in and protect themselves, not to hurt them. At the same time, we should establish more natural reserves for the wild animals.
I believe as long as work together to protect the wild animals, our life will be
more and more comfortable.
