1)在主语从句中的应用 It is demanded / necessary / a pity + that…等结构的主语从句,谓语动词用should 加动词原形,should 可省略。
It is | 可用的词有三类 | that | (should)do | suggested, ordered, required, proposed, demanded, requested, insisted等 | important, necessary, natural, imperative, strange等 | a pity, a shame, no wonder等 |
2)在宾语从句中的应用 在表示命令、建议、要求等一类动词后面的从句中,像order, suggest, propose, require, demand, request, insist, command, insist + (should) do等。例如: I suggest that we (should) hold a meeting next week. 我建议下周召开个会议。 He insisted that he (should ) be sent there.他要求被派到那儿去。 注意:如suggest, insist不表示"建议" 或"坚持要某人做某事时",即它们用于其本意"暗示、表明"、"坚持认为"时,宾语从句用陈述语气。 判断改错: (错) You pale face suggests that you(should)be ill. (对) Your pale face suggests that you are ill. (错) I insisted that you(should)be wrong. (对) I insisted that you were wrong. 3)在表语从句,同位语从句中的应用 suggestion, proposal, idea, plan, order, advice等名词后面的表语从句、同位语从句中要用虚拟语气,即(should)+动词原形。例如: My idea is that we(should)get more people to attend the conference.我的想法是让更多的人来参加会议。 I make a proposal that we(should)hold a meeting next week.我提了个建议,下周我们开个会。 |
