定语从句和同位语从句的区别 从结构上看：同位语由连接词引导。在从句中不担任何成分， 定语从句的关系词在从中担任某个成分。 The idea that one can do the work without thinking is wrong (同位语从句that在从句中不担当任何成分) The idea that you put forward at the meeting is wrong (定语从句that在从句中担任宾语) 主语从句 名词性的从句可作句子主语，这种从句称为主语从句。主语从句的引导词通常有who whom when where why what how which whose whether等， 主语从句的引导词不能省略，由从句做主语时，谓语动词用单数形式 What I said is important to you How to get there is still not decide Whether to do it or not is what we will discuss tomorrow 是否做那件事是我们每天将要讨论的事 说明： 主语从句可以直接放在主语位置，也可用it作做形式主语 1.That light travels in straight lines is known to all It is known to all that light travels in straight lines 众所周知，光是以直线运行 2.When the plane is to take off has not been announced It has not been announced when the plane is to take off 飞机什么时候起飞还没有公布 注： A.当what引导的主语从句表示“……东西”时。不用it作形式语 What he wants is a book B 如果带主语从句的句子是疑问句，则必须用it作形式主语的结构 Has it been settled who will be sent to carry out the task 谁将被派出执行这个任务决定了吗？ C it作形式主语的主语从句结构已形成固定用法和译法， 通常有4种情况 1.It is +名词+从句 2.It is a fact that….. 事实是….. 3.It is a good news that….., ……是个好消息 4.It is a question that…. ……是个问题 5.It is common knowledge that… …..是个常识 1.It is +形容词+从句 2.It is necessary that…有必要… 3.It is clear that.. 很清楚… 4.It is (un) likely that… 很可能… 5.It is important that…主要的是…. 1.It is +过去分词+从句 2.It is said that…据说…. 3.It is reported that… 据报道…. 4.It has been proved that..已证明… 5.It must be pointed out that…必须指出… It +不及物动词+从句 It seems that….好像是…. It happened that….碰巧… It follows that .. 结果是…. 强调句 强调谓语动词时,可在谓语动词前加do, does, did, I do believe that he will attend the meeting He did work hard yesterday 强调句中强调谓语以外的是成分时,采用强调句型： It is (was)+强调部分+that/who/whom 说明：无论强调什么部分,都要求用连接词that 被强调部分是人,也可用who 当被强调部分是状语,只能用that, 不用when, where, how等 例： John bought a toy plane for his son yesterday 1.It was John that (who) bought a toy plane for his son yesterday (强调主语) 2.It was a toy plane that John bought for
