On a rainy day, yon will see many streams of muddy (多泥的) water running down the slopes (斜坡) of a hill. The water is muddy because it washes away soil from the hill slopes.

　　Sometimes soil is blown away by strong winds. When the soil is carried away by water or wind, we say that the land is eroded (侵蚀). This is known as soil erosion.

　　Plants can not grow on eroded land．There is not enough soil on eroded land to give them the things they need．Plants need water and salts from the soil.

　　We can do a number of things to stop soil erosion. This is called soil conservation(保护).

　　One way of soil conservation on flat, open ground is to grow small plants such as grasses. Their roots hold the soil tightly together.

　　Another way is to plant trees around an open field．Thus soil erosion by strong winds can not take place. Rows of trees act as a very big wall.

　　Soil erosion on slopes can be stopped by cutting “steps” called terraces (梯田). Water carrying soil can not run straight down the slope now. It has to run down the terraces. This slows down the flow (流速) of the water. Most of the soil in the water is left behind on the terraces.

(1)On a rainy day the water running down the slopes of a hill is muddy because ________.

[　　]

A．there are no terraces on the slopes

B．there are no small plants on the slopes

C．it washes away soil on the slopes

D．there is too much soil on the slopes

(2)Plants cannot grow on eroded land because _______.

[　　]

A．there is a lot of sand in it

B．there is not enough water and salts in it

C．there is no water in it

D．the land is too hard

(3)The way of soil conservation on flat, open ground is ________.

[　　]

A．to grow small plants such as grasses

B．to plant trees around an open field

C．to add fertility to the soil

D．A or B

　　The conflict (争论) over what or how much homework should be comes partly from the fact that people can't seem to agree on the purpose of homework.

　　What teachers think?

　　Some teachers think that homework is necessary to reinforce (巩固) what is learned in school. And so they ask their students to memorize what was discussed in class through homework.

　　Some teachers think the point of homework is to cover material that the class didn't have time to get to, so their homework is to let students learn additional things.

  Lakeland, Flo. April 29--Two cars fell to the bottom of a 30-foot sinkhole（灰岩坑）that appeared so suddenly that the drivers could not avoid it.

　　No one was hurt, but the incident was the fifteenth of its kind reported in this area so far this year.

　　At a town 13 miles from Lakeland, two bedrooms of one house dropped into a hole 60 feet across and 35 feet deep. Part of the next house was dangerous over the hole. The people in both houses had to be taken to safety.

　　Sinkholes have been happening without warning in this part of Florida for years. So far there is no way to predict（预言）when or where one will appear. But when one does, others usually follow in the same area, usually along a straight line.

　　The worst sinkhole appeared in 1965. It was 70 feet across and 150 feet deep. It destroyed one house and damaged several others.

　　One hole, 15 feet deep, opened up this year in the middle of a highway 19 seconds after a car had driven by. Others in the same area happened at night, damaging houses, swallowing up trees and parts of streets and causing 23 frightened people to run away from their homes in nightclothes.

　　Sinkholes happen when the weather is very dry. The earth at the surface begins to drop into holes underneath. This is how a sinkhole is formed.

（1）Sinkholes do not happen

[　　]

A. after a rainstorm

B. in a straight line

  Can trees talk? Yes--but not in words. Scientists have reasons to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree（柳树）attacked in the woods by caterpillars（毛毛虫）changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special vapour--a signal causing its neighbours to change the chemistry of their own leaves and make them less tasty.

　　Communication, of course, doesn't need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar（花蜜）for honey. So why shouldn't trees have ways of sending messages?

（1）When attacked, a willow tree will protect itself by _______.

[　　]

A. changing its leaves' chemistry

B. changing its leaves' colour

C. talking to caterpillars

D. sending out a special vapour

（2）From the passage we know that caterpillars _______ .

[　　]

A. like willow trees

B. enjoy eating fallen leaves

C. feed on willow tree leaves

D. could communicate with willow trees

（3）Caterpillars will stop eating willow tree leaves which _______ .

[　　]

A. have a chemical change and become tasteless

B. have a pleasant taste

C. are being attacked

D. are communicating

（4）According to the passage, how do willow trees communicate with each other?

[　　]

A. They talk in words.

B. They send out a special vapour.

C. They wave their leaves.

D. They make special sounds.

（5）According to the passage, bees communicate with each other by ______ .

[　　]

  Switzerland is famous for its watches. However, this country didn't invent the watch. It was the British who did it. Here is a story of how the watch was brought to Switzerland.

　　Many years ago, an Englishman was travelling to Italy. On his way he stopped in a small town in South Switzerland. This Englishman travelled in a carriage inside which there was a carriage watch. This was the earliest kind of watch. A native shop assistant happened to see the watch. He wondered what is was and asked the Englishman about it. “It is a carriage watch,”said the man. “This machine tells the time, but now it isn't working.”

　　At once the shop assistant offered to try to repair it. So the traveller handed him the watch. The assistant was a very wise man. So it was not surprising that he managed to repair it. He even remembered how it was made. As soon the traveller had gone on his journey, he made a watch exactly the type.

　　Thus the watch-making started in Switzerland. Today Switzerland watches are sold in stores all over the world.
