So the Moon must fully orbit the Earth, in order to make one complete rotation on its axes.

因此月球必须是足足围绕地球转一圈，才能围绕着自己的轴线自转一圈。

So you tell them that a day is how long it takes for the Earth to complete a full rotation about its axis.

However, the moon takes much longer to complete one orbit around the Earth—about 27 days—than it takes for the Earth to complete one rotation—only 24 hours.

然而月球绕地球公转一圈（约27天）的时间，比地球自转一圈（约24小时）的时间要长得多。

A day, of course, is measured by the amount of time it takes for the Earth to complete one full rotation on its axis.

当然，一天是以地球自转一圈所需的时间来衡量的。

I don't know what it is about the earth completing another rotation around the Sun but there's something about New Year's that makes anything seem possible.

A day on Venus is longer than a year: Venus has an extremely slow rotation on its axis and takes 243 Earth days to complete one rotation, but it orbits the sun in just 225 days.

3.金星上的一天比一年长：金星自转速度极慢，需要243个地球日才能完成自转，但它绕太阳运行一周只需要225天。
