答案

1：even if he came this evening,he wouldn't solve the problem 这句话与过去事实相反,为什不用had+过去分词 与 would have +过去分词而却用过去形式?--------因为讲话的时候,是上午或者下午,还没有到晚上.2：he would have given you more help,but he has been so busy.这里面的has been 是什么东西?完成形态在虚拟语气里面不是要用had+过去分词吗?----------has been解释为“从过去到讲话时为止“,属于“过去”的概念.3：i worte everything down lest i should forget it.这句话为什么是虚拟语气?我怎么看不出来?它与事实相反的地方在哪?-------这不是虚拟语气,lest是连接词,后面的从句谓语结构是 should do -------should可以省略.4：it'is strange that we meet here 这句话为什么是虚拟语气?----------这也不是虚拟语气,只是句型要求：it is strange that -- - -(should) do sth --------其实,在这样的句型里面should并不可以省略.5：who put a fool would believe that --------就语法来说,这是错句.正确的句子是：
whoever put a fool would believe that -------我从来没有碰到这个句子,表达法应该是错的.6：if only grandmother could see this together with us now 这句话为什么不是should而是could --------if only这个虚拟语气的句子里面一般不用should.一般是would- --,或者是一般过去时或者过去完成时-------看句子的时间概念决定.7：he doesn't dare to go out in case he should be recognized 这句话意思是他不敢出去免得被认出来.但是这句话为什么是虚拟语气呢?那个地方是与现在相反?难道现在已经出去了?---------这里的in case与lest的语法功能相同-----请参考你的第三句.8：though the girl had been suffering from the blood disease,she acted as if nothing had happend to her while facing her friends and relation 这里的suffering为什么加ing呢?--------是过去完成进行时,从过去到讲话时为止已经持续了一段时间,并且很可能会延续下去.9：her accent suggest that she comes from south china come为什么加s?这句话不是应该省略了should而should后面应该用原型吗?10：the expression on her face suggests that the secret.哎 真不明白 这句话跟虚拟语气有什么关系?到底有啥关系呢?---------这里的suggest不是虚拟语气结构.在这里解释为“让人看出/ 听出”.
11：what a pity considering his ability and experience he might have done better 并且后面为什么不用should或could而用might?
------- 这里,should ,could和might都是正确的表达,是谁说的-------should不能使用?
我感觉,你的练习书里面有太多的语法上的或者理解上的错误,你的练习书是什么名称?
