When I saw a lot of people gathering over there,I went over to see ______.

问题描述:

When I saw a lot of people gathering over there,I went over to see ______.
A.what was the matter B.what the matter was
C.what was happened D.what was the wrong

选A
这里what短语充当宾语,what引导的是宾语从句,因其在句子中充当宾语成分,因此只需要用正常语序即可,不需要用倒装语序.
所以排除B
Dwhat was wrong.wrong前面不加the
C 这里应该用进行时,因为意思是:正在发生什么.
