理工类考试辅导：阅读理解精选语句
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.
1、美国和俄国的宇宙飞船都已经到达过月球，而且人类也在它的表面上行走过。月球上的岩石和土壤的样本，以及许多其它类型的信息，近些年来已经为人们所知所用了。然而除了我们所知道的关于月球的那些外，还有更多是我们不知道的。
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.
2、在阿波罗太空计划结束后，国家地理协会出版了一组有关月球的极好文章。这里，以简短的形式截取了其中一篇文章重的部分问答。完整的内容，请见1973年九月发行的《国家地理》。
Were scientists right about what the moon would be like?
科学家关于“月球外貌”的描述是正确的吗?
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.
3、大多数是正确的，当然，也有相当部分是错误的。一个说法是月球上没有熔岩。另外一个说法是宇航员的靴子一旦碰上月球物质就会爆炸。有人说月球确实存在水。许多人还认为宇航员有可能把某些奇怪的传染病菌带回地球。这些说法现在被证明都是不正确的，无疑，我们关于月球的许多其它的看法是错误的。
Is the moon like the earth?
月球像地球吗?
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.
4、答案是，像也不像。月球比科学家在阿波罗计划之前想象的还要像地球。如同地球一样，月球上有地层，表面是一层地壳，其下是很深的地幔。月球也可能如同地球一样有一个地核。然而，月球地壳几乎是地球地壳厚度的四倍。我们对月球地幔所知不多，那些过热的岩石在外壳几百英里以下。我们预料，但是我们不能确定，月球有一个由熔岩构成的地核，如同地球。
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.
5、在其它的方面，当然，月球非常不同。它没有生命，没有水。它的大气的构成也非常不同，地球生物在那里不能呼吸。
Of what is the moon made?
月球是由什么构成的?
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.
