Question

我不明白为什么这一道英语单选题不能选C
35 --what are you worried about?
---（ ）.
A.whether we can succeed B.If we succeed
C.who will the boss meet D.Because I lost my purse.
正确答案是选A,但我不明白为什么不能选C呢?
27.( )important knowledge is to us all!
A.How B.What C.How an D.What an
我不明白为什么要选A,而不选B

Answer 1

35.其实这里完整应该是I'm worried about whether we can succeed .所以about后面应该接陈述句,所以C不对!
27.这里表达的意思是 knowledge is important to us all.改成感叹句后就在前面加how.而如果选what则语法不对!
