I read winter vacation a good-looking book, the title is called " the world that views us " .
寒假我读了一本好看的书， 书名叫做《看看我们的地球》。
A lot of knowledge about the earth and earthly interior were explained inside, what I like most is this one part of earthly age. There are a lot of methods to say earthly age inside, have: Theory of the view of astronomical earth age, astronomy says earthly age, geological fact says earthly age, wait …… a moment to say the statement of astronomical earth age first, the interior that Thomson thinks to prove the earth with a variety of methods is even harder than steel, he goes up from heat consider, the age that he says the world does not cross 10 compositions at most 100000000, but if compare,he says 100 million years to return again much, the earth spends the protruding than now in equatorial protruding even should big, and polar should relatively present polar even smooth. We learn to go up from celestial body force consider, do not differ roughly with his opinion again, we cannot decide.
里面讲了许多关于地球和地球内部的知识，我最喜欢的就是地球的年龄的这一部分。 里面有很多方法说地球的年龄，有： 天文学地球年龄的说法、天文理论说地球年龄、地质事实说地球年龄，等等……先说天文学地球年龄的说法，汤姆逊想用种种方法证明地球的内部比钢还要硬，他从热学上着想，他说地球的年龄顶多不过10亿年，但是他又说如若比1亿年还多，地球在赤道的凸度比现在的凸度应该还要大，而两极应较现在的两极还要平。我们从天体力学上着想，又与他的意见大致不差，我们无法确定。
Geological fact says the statement of earthly age, say the world about 1. 50 thousand - 2. 0 years. The history with hot earth says earthly age, say the world about ……
地质事实说地球年龄的说法，说地球大约1。5万-2。0万年。地球热的历史说地球年龄，说地球大约……
This still has a lot of knowledge about the earth inside this book, I suggest everybody goes having a look at this book. Can acquire rife earth knowledge.
这本书里面还有很多关于地球的知识，我建议大家去看一看这本书。可以学到非常多的地球知识。(文/胡欣仪)
