As he is not good at leanring English ,his English ___ very weak

问题描述:

As he is not good at leanring English ,his English ___ very weak
A.still B.remains C.is remained D.is left 要选哪个 为什么

B
后面his English ___ very weak应该是一具完整的话,所以需要谓语动词,排除A.
然后他的英语保持着很差(的状态),是主动的,自己保持的,所以用主动语态,排除C.
is left 被留下的意思,此处不对.
