5. 用在“ It is / was necessary/ important/ strange/ incredible 或“ It is a pity/ a shame/ no wonder 之后由 that 引导的主语从句中, should 有“应该、“必须、“竟然、“居然之意。例如:

It is strange that the wheel should turn so slowly.
真奇怪,这个轮子竟然转动得如此之慢。
It is a great pity/ shame/ that he should be so conceited.
真遗憾,他竟会这样自高自大。
九 . “ should have + - ed 分词结构用来表达下述意义:
1. 表示“应该已经……,“本来应该……,即过去该做某事但实际没有做,其否定式“ shouldn't have + - ed 分词意为“本来不应该……。例如:

You shouldn't have dept those cells in the damp place. 你本来不该把那些电池放在潮湿的地方。(但实际上已经把它们放到潮湿的地方了。)
