The next great land area that man hopes to control is the moon. In size it is nearly equal to the area of North and South America. However, it presents a hostile (不友好的) environment. Temperatures range +120 to -150 degrees Centigrade (摄氏). There is no air, and no water.
Today there is considerable scientific speculation (思索) about living on the moon. When man will begin life on the moon surface is still not determined. But experts believe that settlement will take place in three steps. First, there will be increasing periods of exploration with temporary shelters (临时住所). These periods will be followed by longer stays with housing under the surface of the moon and daily necessities brought by the settlers themselves from the earth. Finally, settlements that are self-supporting will be founded.
The main job of the early settlers will be to stay alive. They will have to plant crops under huge domes (圆顶屋) to produce food and oxygen and find water sources. After this is done, the settlers will have time to explore the possibilities of commercial (商业的) development and to make discoveries important to science. The characteristics of the moon that make it bad for human staying alive may make it ideal for certain kinds of manufacturing (制造业). Operations requiring a vacuum (真空) or extreme cold are examples. Therefore, industrial diamonds might be produced on the moon.
64. The area of the moon is _________.
A. about the same as that of North and South America
B. larger than that of North and South America
C. hardly equal to that of North and South America
D. far smaller than that of North and South America
65. According to this passage, the settlement of the moon ________.
A.will soon be realized
B.can be done under the moon surface
C.is being experimented by many scientists
D. sounds entirely impossible
66. To stay alive on the moon, the early settlers must first of all be able to ________.
A. develop commerce
B. get enough food, oxygen and water
C. make discoveries important
D. explore the possibilities of industrial development
67. Though the environment on the moon is bad for human staying alive, it is very good for ________.
A. making such things as industrial diamonds
B. all kinds of manufactured goods
C. medical operations
D. commercial development

Whenever human populations have lived in forest areas, they have always cut down trees which they used for a number of purposes, for housing and ships and served as a source of heating fuel and timber. Growth of cities often meant expansion into forest areas, while even more trees were removed to provide space for agriculture. With the growing demand for paper, vast quantities of trees have also been cut down for paper production. These factors, along with many others, have been contributing to a dangerous phenomenon known as deforestation.

In the last 5,000 years, humans have reduced forest from roughly 50 percent of the earth’s land surface to less than 20 percent. Most of this original, or old growth, forest cover is concentrated in three large areas: the Canadian and Alaskan boreal forest, the boreal forest of Russia, and the tropical forest of the northwestern Amazon Basin and the Guyana Shield. These areas comprise almost 70 percent of the world’s remaining original forest cover. In most places, the rate of deforestation is increasing, with the alarming result of 16 million hectares disappearing worldwide every year.

Loss of forest does not just mean the decline of natural resources. There are several other factors that make deforestation seriously harmful to both the human and natural worlds. One of them is changes in the global climate. For example, forest clearance is releasing substantial volumes of carbon dioxide (CO₂) into the atmosphere as vegetation is burnt or decays. It has been suggested that this is a significant factor in global warming. Moreover, about 10 percent of the world’s tree species are in danger of extinction as a result of deforestation. Deforestation also threatens biological diversity through the destruction of wildlife habitats, which endangers a number of animal species and leads to their potential disappearance. Species are particularly easy to extinction in tropical rainforests because many species have few individuals per unit area, which makes reproduction more difficult. Finally, since forests play an important role in storing water and stabilizing soil, deforestation and the resulting change in land use cause soil erosion (腐蚀) and other forms of land degradation.

1.The passage discusses all of the following EXCEPT the ________.

A. causes of deforestation B. consequences of deforestation

C. management of deforestation D. rate of deforestation

2. The word “diversity” in the last paragraph probably means “________”.

A. variety B. expansion

C. development D. advantage

3.Why does the author mention fuel and timber in Paragraph 1?

A. To explain the rate of deforestation.

B. To compare them with housing and ships.

C. To show the dangers of deforestation.

D. To illustrate the causes of deforestation.

4.Which of the following sentences summarizes Paragraph 3 best?

A. Deforestation threatens biological diversity.

B. Deforestation has many harmful consequences.

C. Deforestation causes changes in global climate.

D. Deforestation should be stopped.

American cities are similar to other cities around the world. In every country cities reflect the values of the culture. Cities contain the very best aspects of a society: opportunities for education employment and entertainment. They also contain the very worst parts of a society: violent crime, racial(种族) conflict and poverty. American cities are changing just as American society is changing. 　　

After World War II city residents became wealthier. They had more children. They needed more space. They move out of their apartments in the city to buy their own homes. They bought houses in the suburbs areas near a city where people live. These are areas without many offices or factories. During the 1950s the American “dream” was to have a house in the suburbs.

　　Now things are changing. The children of the people who left the cities in 1950s are now adults. They unlike their parents want to live in the cities. Many young professionals, doctors, lawyers and executives(主管人员) are moving back into the city. Many are single; others are married but often without children. They prefer the city to the suburbs because their jobs are there; they are afraid of the fuel shortage; or they just enjoy the excitement and opportunities which the city offers.

This population shift(转变) is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these people do not have enough money to stay in the cities.

Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is for sure：many dying cities are alive again.
