Question

几道英语单向选择,越详细越好.
1.The extra room ______(to be) very useful when we had visitors.
A.was proved B.has been proved C.has proved D.proved
2.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

Answer 1

D
prove没有被动形式,此句是说当．．．的时候,所以用和从句相同的过去时而不用完成时
A
what was the matter本身就是正装语序,因为它的主语是what所以不用说what the matter was
C显然不对was happened是被动,应该说what was happening
