I'm one of the places where the earth axis intersects its surface.

我是地球旋转轴同地表的交汇之地。

See if you can I.D. me. I'm one of the places where the earth axis intersects its surface.

看你能不能认出我。我是地球旋转轴相交的地方。

As we spread out, a slight shift of the earth's axis Away from the sun cools the planet.

随着人类的分散，地轴相较太阳的轻微偏转，使得地球温度有所下降。

This discrepancy is due to the complications of the earth's orbit being elliptical and the earth's spin axis being tilted.

这种差异是由于地球的轨道是椭圆形的，而地球的自转轴是倾斜的。

Precession, basically is the change in the direction of earth’s axis of rotation.

进动，基本上是地球自转轴方向的变化。

Which would explain why summer seems to zip by, except the seasons are a function of the tilt of the earth's axis, not its different distances from the sun.

这就解释了为什么夏天速度移动的飞快，当然是除去地球轴性导致的倾斜从而产生的季节因素，地球与太阳之间的距离也不是原因。
