【特别说明】
(1) 在现代英语中，有时也可不⽤虚拟语⽓⽽⽤陈述语⽓，但初学者宜慎⽤。
(2) 在It is amazing (strange, surprising, astonishing, a pity, a shame)以及 I am surprid (sorry) 和I regret等结构后的that 从句中有时也⽤should，表⽰说话⼈的惊异、懊悔、失望等情感，常含有“竟然”之意：
It’s strange that he should be so rude. 他竟如此⽆礼，真是奇怪。
I’m surprid that he should have failed. 他竟然失败了，这使我很吃惊。
若不⽤虚拟语⽓也可以，则不带感情⾊彩，⽐较：

t he failed the exam. 他考试没及格，真是遗憾。
It’s a pity that he should have failed the exam. 他考试竟没及格，真是遗憾。
