虚拟语气中,should +动词原形的这种结构 后面的动词原形就真的是真正的动词原形连加S都不可以么 His desire is that he (should )visit the Great Wall of China someday It is imperative that the experimenter make accurate measurements It is important that each of you bring a note-book to class with you every day 在书中看到这些句子请问这样子的话,我可不可以说这种类型(should +动词原形)的后面是不用加S的 只要动词原形就可以了(visit make bring ) We____better under more favorable conditions A.do B did C had done D would have done
1、should在这里就相当于情态助动词,起一部分助动词的作用, 后面的动词当然用原型了,也就是什么变化都没有. 2、省略虚拟分句的句子,表虚拟,叫做含蓄条件虚拟 选D 一般这样的句子都是从句子含义或者上下文来判断,当然也只有丰富的句子含义才能做出判断. 这个句子中有明显的提示词:under more favorable conditions He would be much more rich without three children
