Unit 24 Society 语法篇____________________________________________________________________________________________________________________________________________________________________1、虚拟语气—在书面语中2、虚拟语气—在口语，非正式用语中一，虚拟语气—在书面语中1.用“should/ought to+动词原形”的形式。
We should go out foe a walk.You ought to study hard for your future.温馨提示：should和ought to都表示“应该”，一般可以互换使用，但是should含有“按我的想法应该…”的意思；ought to语气强烈，强调“有责任，义务或按道理应该…”的意思。
2.有些动词后跟宾语从句时，从句的谓语用“should+动词原形”，should可以省略。
此类动词可以用“一，二，三，四法”进行记忆。
①一个“坚持”，即insist。
He insisted that we (should) attend the meeting.②两个“命令”，即order和command。
The boss ordered all the workers (should) be there on time.③三个“建议”，即suggest, advise, recommend。
He suggested that we (should) go out for a walk.④四个“要求”，即demand, require, request和desire。
I demanded that he (should) answer me as soon as possible.注意：当suggest表示“暗示，表明”：时，insist表示“坚持说”时，后面的从句不用虚拟语气，用陈述语气。
3.在“It’s desired/ suggested/ required that…”句型中，后面的主语从句的谓语动词用“should+动词原形”，should可以省略。
It is desired that we (should) get everything ready by tonight.4.在suggestion, proposal, order, advice, demand等名词后接的表语从句或同位语从句中，谓语动词用“should+动词原形”，should可以省略。
There’s no suggestion that you (should) resign.5.在“It is (high) time that…”这一特殊句式中，谓语动词用过去式或should do的形式表示虚拟，should不能省略。
It’s time that we went home.二，虚拟语气—在口语，非正式用语中1.用if I were you, I’d…句型，语气更委婉，含蓄。
If I were you, I’d go with them.2.用I think you should /ought to do…句型，语气稍强。
I think you should buy him a gift.3.如果要强硬的批评，责备某人或提出建议，可用下列句型：①It’s about/ high time that…It’s about time you got down to reading.②You’d better do sth. / You’d better not do sth.You’d better give him some advice on it.③I’d rather sb. did sth.I’d rather you came tonight.例 1.
