Answer 1

你好这里考查的是虚拟语气

根据后面的 would not have suffered 可以看出是与过去事实相反，
主句为：he would not have suffered such a heavy loss in his business.
他的生意就不会遭受如此打的损失
从句应该用过去完成时，所以选 D

Answer 2

这是一个与过去事实相反的虚拟语气，根据规则，A、B、C都不是正确选项。
在虚拟语气的条件从句部分，可以省略if，此时从句的倒装。
这句补上IF：
If he had taken....

Answer 3

解答：
他采纳了朋友建议没有，他不能在事业上再遭受这样的强大打击。
首先采纳建议应在是否有可能遭受打击的前面，既然有可肯能遭受打击用的是过去时，所以采纳建议当然得用过去完成时。
谢谢

Answer 4

考查过去时的虚拟语气。if-从句的谓语动词用had done，如果省略if，则把助动词had移到前面，进行部分倒装。

Answer 5

过去完成时 虚拟语态
