asif;suggest的用法.docVIP

as if 的用法 as if 好像，好似 She spoke to me as if she knew me. 她和我说话的神情，好像她早就认识我似的。 (= as though) 一、as if 从句的作用 1 在look, seem 等系动词后引导表语从句。如： She looks as if she were ten years younger 她看起来好像年轻了十岁。 It seems as if our team is going to win 看来我们队要胜了。 2 引导方式状语从句。如： She loves the boy as if she were his mother 她爱这男孩，就好像她是他的母亲一样。 The child talked to us as if he were a grownup 那孩子跟我们谈起话来，像个成年人似的。二、as if 还可用于省略句中 如果as if 引导的从句是“主语系动词”结构，可省略主语和系动词，这样as if 后就只剩下名词、不定式、形容词（短语）、介词短语或分词。如： He acts as if （he was） a fool 他做事像个傻子。 Tom raised his hands as if （he was going） to say something 汤姆举起手好像要说什么。 She left the room hurriedly as if （she was）angry 她匆忙离开房间好像生气的样子。 三、as if 从句的语气及时态 1 as if 从句用陈述语气的情况。 当说话者认为句子所述的是真实的或极有可能发生或存在的事实时。如： It sounds as if it is raining 听起来像是在下雨。 He talks as if he is drunk 从他谈话的样子来看他是醉了。 2 as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下： （1）如果从句表示与现在事实相反，谓语动词用一般过去时。如： You look as if you didn t care 你看上去好像并不在乎。 He talks as if he knew where she was 他说话的样子，好像他知道她在哪里似的。 （2）从句表示与过去事实相反，谓语动词用“had过去分词”。如： He talks about Rome as if he had been there before 他说起罗马来好像他以前去过罗马似的。 The girl listened as if she had been turned to stone 那女孩倾听着，一动也不动，像已经变成了石头似的。 （3）从句表示与将来事实相反，谓语动词用“wouldcouldmight动词原形”。如： He opened his mouth as if he would say something 他张开嘴好像要说什么。 It looks as if it might snow 看来好像要下雪了。Suggest用法小结1 Suggest表示建议，用法如下：1) Suggest+ 名词/代词或suggest+名词/代词to+人，但不能说suggest sb sth ,即不能加双宾做宾语eg: We suggest him the plan ()但We suggest the plan to him()2）suggest+doing stheg He suggested going out for a walk.注意：suggest 不可以加不定式，所以上面的句子不可以这样写： He suggested to go out for a walk.()4suggest +(that )+主语+(should) do+sth 其中的should 可以省略eg: He suggested that you should go there tomorrow.=He suggested you go there tomorrow.注意，不可以这样说：He suggested you to go there tomorrow.也就是说suggest不可以加不定式的复合结构。5）it is suggested that +主语+(should )do sth eg: It is suggested that the work (should) be finished at once.6)suggestion做主语时，其后的表语从句也用这个结构即：The suggestion is that +主语+should +do stheg: His suggestion is that I should leave for Beijing
