"在山脚下有一个小山洞"用英语怎么说

there is a cave at the foot of the mountain

There is a small cave(hole) at the foot of the mountain.

同上,这TMD也太简单了……

Have a small cave on the foot of a mountain

There is a cave at the foot of the mountain.

There is a small cave at the foot of the mountain。
这应该是考there be句型的使用和at the foot of the mountain这个短语吧
