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。
