2023年職稱英語理工類閱讀理解中英文對照精選練習題

　　1. Spacecraft from the United States and from Russia have been to the moon, and men have walked upon its surface. Rock and soil samples and information of many other kinds have become available in recent years. Yet with all we know about the moon, there is even more that we dont know.

　　2. Following the end of the Apollo space program, the National Geographic Society published an excellent set of articles about the moon. Here, in shorter form, are some questions and answers from one of these articles. For the full story, see the September, 1973, issue of National Geographic.

　　Were scientists right about what the moon would be like?

　　3. Many were, of course, but many were mistaken. One said there was no lava on the moon. Another said that the moon material would explode as soon as an astronauts boot touched it. One said there would certainly be water on the moon. Many felt there was a chance that the astronauts could bring back to earth some strange infection. These ideas are now known to be incorrect, and no doubt we are still wrong about many other things, also.

　　Is the moon like the earth?

　　4. Yes and no. It is more like it than many scientists thought before Apollo. Like the earth, the moon is in layers, with a crust on the outside and a deep mantle below. It may also have a core, as the earth does. However, the crust is almost four times thicker than the earths crust. We do not know much yet about the moons mantle, that section of superheated rock which goes down hundreds of miles below the crust. We think-but we are not sure-that the moon has a center core which includes molten rock, as the earth does.

　　5. In other ways, of course, the moon is very different. There is no life, and there is no water. The makeup of its atmosphere is very different; the earth creatures cannot breathe in it.

　　Of what is the moon made?

　　6. Definitely not green cheese. It has the same chemical elements as have the earth and the rest of the solar system but in very different amounts-more of some, less of others. Carbon, which is a very important part of living things on the earth, is rare on the moon.

　　Is the moon hot or cold?

　　7. Most scientists agree that some of the moon was hot for at least a time. Rocks from the moon show that they were once melted. Right now there seems to be heat someplace inside the moon, possibly a great deal of it. On the surface, however, there is no sign of heat-no volcano, for example. The surface itself ranges from heat of 230℉ to cold of minus 290℉,depending upon where the sun is.
