虚拟语气--名词性从句中的虚拟语气：深国交入学英语
在英语中有陈述语气，用于平铺直叙客观情况。而虚拟语气，顾名思义，不是真实的客观的情况，而是主观的（说话人）命令，要求，建议等，事实上并未发生。在形式上用should+do来标明这是虚拟语气。巧记1：名词性从句中的虚拟语气名词性从句:-------------------------- 主语从句，宾语从句，表语从句，同位语从句。1) 宾语从句: 10个动词+that sb. (should) do例：I suggest that he (should) work hard.我建议他努力学习。巧记2：与suggest用法相同的10个动词
思考：为什么这些词要用虚拟语气呢？因为：你命令要求建议或坚持让某人去做某事，事实他还没做，这就是虚拟语气。所以要注意：suggest表暗示表明； insist表坚称时，不用虚拟语气。He insisted that he didn't cheat in the exam.他坚持说他没作弊。His embarrassed look suggested that he was lying.他尴尬的表情表明他在撒谎。2)主语从句：It is/was +10个动词（-ed）+sb.(should) do例：① It is suggested that he should work hard. 据建议他该努力学习。注意：It 作形式主语使用虚拟语气的句式还有② It is important, necessary，strange…that+ (should) do③ It is a pity, a shame, no wonder… that+ (should) do④ It is (high/about) time that sb. should do/did sth.(should不可省略）到某人做某事的时间了，事实上还没做，所以用虚拟。注意：在句式②③中，should除译为应该外，有时表竟然。例句：It is strange that he should arrive so early.他竟然这么早就到了，真是奇怪。It is a shame that he should cheat in the exam.他竟然考试作弊，真是可耻。3)表语从句: 10个名词+ be+ that+ sb. (should) do例：My suggestion is that he (should) work hard.我的建议是他该努力学习。注意:10个动词的名词形式如下1坚持：insistence2命令：order, command3要求:demand, requirement,request4建议:advice,suggestion,proposal，recommendation4)同位语从句：10个名词+ + that+ sb. (should) do例：He didn’t follow my suggestion that he (should) work hard.他没有听我让他努力学习的建议。【本文转载自今日头条：英语语法实验室】
