While crossing the mountain area, all the men carried guns lest they _______ by wild animals.
A. should be attacked B. had been attacked
C. must be attacked D. would be attacked
答案选A，为什么？为什么不选B？
A. should be attacked B. had been attacked
C. must be attacked D. would be attacked
答案选A，为什么？为什么不选B？
因为lest后面要接虚拟语气,虽然B中的过去完成式也是虚拟语气的常用表达方式,但过去完成式只能用来虚拟过去的情况,也就是表达过去未完成的打算,过去要做却没做的事,
如I wish I had been able to speak to her before she died.我真希望在她去世之前跟她说上过几句话.(但事实上她已经死了,这是没实现的事情)
而这道题目中lest是"惟恐,以防",显然防的是将来可能发生的事情,所以不用B.
因为lest should 是固定搭配
lest前面是不是少了个at啊?
这个句子的意思是当人们crossing the mountain area时都带着枪枪,为了不受到wild animals的攻击,这种攻击的很可能发生的,是虚拟语气
had been attacked的话 就是他们已经被攻击了,不合常理
