(2011·安徽卷)B

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources(来源), as well as one of the oldest. Evidence shows that windmills(风车)began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind(磨碎)wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

60. From the text we know that windmills              .

A. were invented by European armies

B. have a history of more than 2800 years

C. used to supply power to radio in remote areas

D. have rarely been used since electricity was discovered

61. What was a new use for wind power in the late l9th century?

A. Sailing a boat. 

B. Producing electricity.

C. Grinding wheat into flour.

D. Pumping water from underground.

62. One of the reasons wind was rediscovered in the 1970s is that             .

A. wind power is cleaner

B. it is one of the oldest power sources

C. it was cheaper to create energy from wind

D. the supply of coal and gas failed to meet needs

63. What would the author probably discuss in the paragraph that follows?

A. The advantage of wind power.

B. The design of wind power plants.

C. The worldwide movement to save energy.

D. The global trend towards producing power from wind.

【解析】选D。推理判断题。根据末段句子Today, there is a global movement to supply more and more of our electricity through the use of wind可知,接下来作者应该谈论利用风能发电的情况,因此选择D项。

Freezing can keep food fresh and safe to eat. Freezing lowers the food temperature below zero degree Celsius. That is the point where water turns to ice.    , it is important to lower the temperature to between minus fifteen and minus twenty degrees Celsius as quickly as possible. The faster the freezing process is, the fresher the taste of the food.

Fruits and vegetables can be spread out inside the freezer. Once the food is frozen,     . Fruits are usually not cooked before they are frozen. This allows them to keep their fresh taste. The simplest way to prepare fruits is to cut them up and place them in a container inside the freeze before putting it in the container. This will keep it from sticking to the container. This is called the “dry pack” method.

    , The fruit is prepared along with some of its liquid or juice. You can ad some sugar to fruits that are naturally juicy. The sugar sweetens the fruit and brings out its natural juices.

    . Blanching means placing the vegetables in boiling water for a few minutes and then quickly placing them into very cold water. Blanching slows down the natural chemical aging process. All extra water should be removed before placing the vegetables into containers and freezing.     .

A. it should be placed in containers and then stored at a temperature of about minus twenty degrees Celsius

B. Vegetables are either cooked or blanched before freezing

C. To start the freezing process

D. To keep them fresh for a long time

If you want your land to keep fertile, you must try to stop soil from being carried away by water or wind. When soil is taken away by flowing water or blowing winds we call it soil erosion. Ways have been found to stop soil erosion, and this is known as soil conservation. One way of stopping soil erosion is to grow small plants such as grass. These plants are referred to a cover crops, whose roots hold the soil tightly together. The rain water can not wash away the soil. When trees and tall bushes are planted at the edges of an open field, soil erosion by strong winds can not take place. The trees and bushes, which act as a very big and firm wall, protect the open land from the winds. The way to stoop soil erosion on slopes is to build terraces on the slope of hillside and mountainside. When the slope of a hillside is cut into “step”, water carrying soil can not run straight down the terraces, which are used to slow down the speed of the flowing water containing much soil in it. In this way most of the soil in the water is left behind on the terraces, much soil in it.

1.What takes place in soil erosion?

A.   Flood happens to the fertile land

B.    A large quantity of the soil loses away gradually.

C.    Terraces are built on the slope of hillside or mountainside.

D.   Plants are grown to protect the open land

2.“Cover crops” in this passage means _________.?

A. grass        B. trees and bushes     C. plants life and an area

E.    covering plants that produce grain or vegetables

3.Besides growing small plants, another method to fight against soil erosion is to ___________.

A. build terraces  B. build walls    C. plant trees    D. plant tall bushes

4.According to the passage, trees and tall bushes are planted around an open field ________________.

A.       because their roots hold soil tightly

B.        to stop soil from being blown away by winds.

C.        Because soil erosion causes terrible damages to crops

D.       To keep the balance of nature

5.Which of the following is the best title of the passage?

A. What Causes Soil Erosion

B. The Importance of Erosion

C. Rain Erosion and Wind Erosion

D.Erosion and the Way of Tight against Erosion
