Answer 1

1
d.是(should)+fail，for
fear
that用加should的虚拟语气
2
b。表示过去已经发生的事。如选d表示与现在事实相反
3
跟第二题同一类型
4
这句话的意思是“我们打比方你还能够再去那里，你将有什么感受”，这件事是想象中的，不是实际的，所以用虚拟语气
5
lest(否则)，in
case，for
fear
that，suggest
，purpose，order，require等后加用(should)+v
6
wish后面的从句中，如果指现在或将来的愿望，动词用过去式，而表示过去没有实现的愿望，动词用过去完成时
7
as
if
，as
though后面的方式从句中，表示与现在事实相反或对现在的情况有所怀疑，动词用过去时，如果表达的是想象中的过去的动作，用过去完成时
下面的只有通过语感了，感觉是虚拟语气，就不会选错了，比如说最后一题，知道是虚拟语气，就这能选a
