7、大多数的科学家认为月球的一部分至少在一个时期是热的。来自月球的岩石表明它们曾经被融化。现在,似乎在月球内部的某些地方仍处于高温,也可能它是很大的一片地方,然而在表面上,没有高温的特征,例如没有火山。月球表面温度范围从华氏正230度到华氏负290度,取决于太阳在什么地方。
Where did the moon come from?
月球来自哪里呢?
8. We dont know. The three main theories are that the moon was born from the earth, that the earth and the moon were born together at the same time from the same cloud of gas and dust, and that the moon was born someplace else in the solar system and then captured by the earths gravity. So far, none of these theories has been proved to be either right or wrong. Professor George W.Wetherill of the University of California in Los Angeles says that he would give the first two theories each a 10 percent chance and the third theory a 20 percent chance. The other 60 percent he would give to things we havent thought of yet.
8、我们不知道。主要存在着三个理论:月球产生自地球,地球和月球在同一时间从同一气云和尘埃里同时产生,月球是产生在太阳系的其它某个地方,而后被地球的地心引力所捕获。到现在为止,这些理论中没有任何一个已经被证明正确或错误。洛杉矶加州大学的乔治教授说,他认为前两个理论有百分之十的正确性,第三个理论有百分之二十的正确性,另外的百分之六十他将给至今我们都还没想到的事物。
