改错Can't you see the words on the blackboard?No.But I don't know the answers to it.

Can't you see the words on the blackboard?
No.But I don't know the answers to it.
呵,英文的回答是对,我看到了,不,我看不到.而不像中文,所以应该是
Can't you see the words on the blackboard?
Yes.But I don't know the answers to it.
你看不到黑板上的字吗?
看到了,但我不知道怎么回答.这个问句前还有一个问句，连起来看，还有错吗？Why can't answer my questions?Why can't answer my questions?没有主语，应该是Why can't you answer my questions?
