Question

____made many contestants angry is ____ was called the fair play
play turned out to be unfair at all.
A.what that what
B.What,what
C.It,that
D.It,what that
为什么后面那个空格要填 that what 填一个what不就好了么?不懂

Answer 1

A
that是引导表语从句的,没有词义,不能充当从句是主语,再用what这个有词义的连接代词做了从句的主语,若 填一个what的话就不能很好地让读者看明白is后面是一个从句,况且what是“所.的事物”,而that根本没有这个词义,无法取代what
