问题描述:

There are 9 large planets____around the sun,the earth__one of them
A.being moved ,being B moving ,being
C,moving,is D being moved ,is
没理由啊.我妈说是森么有逗号要时态统一 是这样么?
我错了- - 打错了 手一滑饿

这个问题跟时态毫无关系,
There are 9 large planets____around the sun,the earth__one of them
题目句意为 太阳周围有九个行星,地球就是其中一个.
句首 there are,are是be动词,後面跟名词或者动名词.
A和D 首先排除, being moved 是被动,前部份译为:太阳周围有九个行星.(被动何在?)
然後 B 和 C.
然而 A选项的 is 放入句子里面 the earth is one of them 刚好合适.
地球就是其中一个.

其实,
应该是 and the earth is one of them
这句话才通顺
