lest ,in case ,for fear that虚拟语气后从句用should/would /could/might+do的区别
While crossing the mountain area,all the men carried guns lest they __by wild animals.
would be attracked /should be attracked
Tmad man was put in the soft-padded cell lest he would injure himself.(1997.12.CET4)
这题A.injure为什么不行
有语法书上说lest ,in case ,for fear that虚拟语气后从句用should do,in case 后should不可省,lest ,for fear that后should可省

你是说the mad man was put in the soft-padded cell lest he injure himself.用injure而不是would injure?
这三个词有些语法书是说三个都可以省略should 的.具体做选择题可以灵活点,做填空题什么的,就都用上should,就不会错了.

是不是几个"以防万一"in case lest for fear that 引导的从句必须是虚拟语气should+动词 for fear that in case lest 必须是should 虚拟语气吗?但是我in case 后面跟陈述句 for fear that lest in case 后面必须接虚拟语气吗?有哪几种形式的虚拟? 关于lest,for fear that,in case的虚拟语气用法 for fear that,in case,lest引导目的状语从句什么有区别吗关于lest,for fear that,in case的用法 for fear that /in case/lest引导的是目的状语从句还是结果状语从句?理由? request等命令、建议动词后,从句用虚拟语气（should）do.可以用could,would,might+do吗? for fear that /in case in case that 后的虚拟语气不是有两种情况吗?一种是should do 另外一种是过去式 in case that ,for fear that 区别虚拟语气,与过去事实相反 :从句 :had + 过去分词主句 :would/ should/ could/ might
