Jack is a great talker.It's high time that he __ something instead of just talking.

问题描述:

Jack is a great talker.It's high time that he __ something instead of just talking.
A.do
B.did
为什么选B不选A?

这里涉及词组 It's high time did sth 表示做.的时候到了
是要固定记忆的搭配,在例句里翻译为,JACK是很好的发言者,现在是他该做的点什么来代替仅仅发言的时候了.可 It's high time did sth中的is可不是过去式啊,不是说句子的时态要一致吗(除客观真理外)是的,所以我说这是特殊的固定搭配~区别只在time前面的词如果是别的,it is the right time to do ,it is the correct time to do 或者仅仅是it is the time to do都是 to do 的格式,只有high time后面是用did的,不过这种特殊用法在高中阶段只有这样一个~
