The earth's darker inner shadow is known as the umbra, and the lighter outer one is called the penumbra.

地球内部较暗的阴影被称为本影，较浅的外部阴影被称为半影。

But travel to a spot within the path of the dark inner shadow, called the umbra, and you'll experience the majesty of a total eclipse.

然而如果你进入到阴影的里层部分-“本影”，你将体验到雄伟壮观的日全食。
