1A
It pains sb.to do sth.使某人难过痛心的是
参考
考点是句型,否则ABCD四格答案都有道理
2B
也就是说,这句是特例,只有2个用法,和it is time...一样
It is (high) time that后面的从句谓语动词要用过去式或用should加动词原形,但should不可省略.
It is time that the children went to bed.
It is high time that the children should go to bed.
3B
考察的是see sb doing结构
以及被动语态a rope ladder显然是被扔出来的,如果用主动,那么绳梯就是自己出来的,那就不对了
那么两者结合,就出来了
4B
这是虚拟用法!
It be essential that 后面一定用虚拟语气,且句子谓语动词固定为(should) + 动词原型
类似还有
it is +necessary等形容词后,that主语从句中虚拟形式使用,这类形容词包括necessary,important,essential,imperative,urgent,preferable,vital,advisable等
===
首先,判断说的这件事有没有发生过,这里再说检查什么的,那就是说还没发生过,那就是归于should一类的
===
这个可以和insist放在一起记忆,坚持没发生过的事情,用should虚拟,反之则不用
==
还有,如果选项出现must be checked,虽然意思看着对,但不适合
