it is settled that when we are to have sports meet.哪里错了?

问题描述:

it is settled that when we are to have sports meet.哪里错了?
答案"that"是错的,这里选择不填.这是为什么呢?这句是定语从句?when we are to have sports meet是定settled?所以that不要?

这句话是一个后置的主语从句.
It是不定代词做主语,它指代的就是后面的从句
把这句话还原就是:when we are to have sports meet is settled .
中文意思就是我们什么时候开运动会已经决定了.所以不需要that了.
