1Did改had
虚拟语气。这里省略if ,had提前
2did I know
词组,逻辑都用对了。但是忽略了句首的only如果后面跟了副词、介词短语或从句等状语,则主句用倒装结构
3How改What
It is fun to do sth./ What fun it is to do sth.
用法问题
4hardly ...when
no sooner..than
所以答案显而易见than改when
5On the top of the hill stands a temple
原句应该是
a temple stands On the top of the hill
要用全倒装。
理论:由地点和时间副词引出的完全倒装句
相似句:here comes the bus
