The next great land area that man hopes to colonize is the moon. In size it is nearly equal to the area of North and South America. However, it presents hostile (敌对的) environment. Temperatures range from +120 to－150 degrees Centigrade.
There is no air, no water.
Today there is considerable scientific speculation about living on the moon. When man will begin life on the lunar surface is still not determined. But experts believe that colonization wilt take place in three steps. First, there will be increasing periods of exploration with temporary shelters. These periods will be followed by longer stays with housing under the surface of the moon and daily necessities brought by the colonizers themselves. Finally, colonies that are selfsupporting will be established.
The main job of the early settlers will be able to stay alive. They will have to plant crops to produce food and oxygen and find water sources. After this is done, the settlers will have time to explore the possibilities of commercial development and to make discoveries important to science.
The characteristics of the moon that make it bad for human may make it ideal for certain kind of manufacturing. Operations requiring a vacuum, extremely cold or sterility (无菌状态) are examples. Industrial diamond may be produced on the moon.
1．The area of the moon is ________.
[ ]
A．about the same as that of the North and South America
B．larger than that of North and South America

2．The temperature on the moon can be as high as ________.
[ ]
3．According to the passage, the colonization of the moon ________.
[ ]
A．will be realized
B．can be done under lunar surface
C．is being speculated by many scientists
D．sounds entirely impossible.
4．To stay alive on the moon, the early settlers must first of all be able to ________.
[ ]
A．explore the possibilities of commerce
B．get enough food, oxygen and water
C．make discoveries important to science
D．set up industries
5．Though the environment on the moon is bad for human survival, it is very good for ________.
