《柯林斯英汉双解大词典》

They were started by slow and subtle shifts in the orbit of the Earth that changed the amount and distribution of radiation reaching us from the sun.

地球轨道缓慢而微弱的变化改变了阳光照射我们的数量和辐射的分布，从而引发了这些变化。

It follows that the Moon's orbit is primarily determined by the gravitation pull from the Sun, so the orbit of the Earth will always curve towards the Sun.

由此断定月球的轨道主要由来自太阳的牵引力决定，所以地球对于太阳的轨道一直是椭圆形的。
