1.第一题是虚拟语气考点的一个特殊句型,意思是“早该做某事了”基本结构是 it is (high) time that sb.did sth.
it is (high) time that sb.should do sth
这个句型中的should不能省略.
此外还有个特殊句型虚拟,就是would rather +句子 用过去时是对现在的虚拟,用过去完成时时对过去的虚拟.
eg .i would rather you posted the letter now.
i would rather you had returned the book yesterday.
2.我们搬到城里这样就可以经常去看我们的父母了.
答案应该是C,so that 引导目的状语从句,从句中必须要有情态动词,这也是和so that 引导的结果状语从句的区别.
3.lest 引导的从句应该使用虚拟,从句的谓语动词用should do ,should可以省略.这道题中涉及到了被动,所以是（should）be done.在这种虚拟当中,只能用should不能用would.是固定的.
