1、Unit 1 The world of our senses在复合句中起名词作用的从句叫_(Noun Clauses）。名词从句的功能相当于名词词组,它在复合句中能担任_等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。名词从句名词从句主语、宾语、表语、同位语、介词宾语名词性从句在功能上相当于名词His job is important.What he does is important.主语This is his job.This is what he does every day.表语I dont like his job.I dont li

10、is is what we are looking for.这就是我们所寻找的。(2)疑问词引导的名词性从句要求使用陈述句语序，不能用一般疑问句语序。他是怎么成功的仍然是个谜。How he was successful is still a puzzle.How was he successful is still a puzzle.FT你能告诉我他住在什么地方吗？Could you tell me where he lives?Could you tell me where does he live?TF二、名词性从句连接词的选用(1)that 和what 的选用that 和 what 都可

11、引导所有的_。但是，what除起连接作用外，还在名词性从句中_，可作从句的主语、宾语或表语。而that在名词性从句中_，只起_作用。名词从句充当成分不充当任何成分连接1._ he wants is a book.2._ he wants to go there is obvious.3.The result is _ we won the game.4.This is _ we want to know.5.Is _ he told us true?WhatThatthatwhatwhat6.We should pay attention to _ the teacher is saying.

12、7.I have no doubt _ he will come.8.I have no idea _ he did that afternoon.whatthatwhat(2)if 和whether 的选用 whether和 if 都可以使用的情况：1)引导动词的宾语从句时；2)在be+adj.之后时；3)在主语从句中，it 用作形式主语时。只能用whether的情况：在非正式文体中，if.or not 也是正确的。但与or not直接连用时，只能用whether(即whether or not)，而不能用if(即if or not)；引导表语从句和同位语从句时；引导主语从句，且位于句首时；

13、引导介词后的宾语从句时；后面直接跟动词不定式时；if引起歧义时。1.I asked her _ she had a bike.2._ we will hold a party in the open air tomorrow depends on the weather.if/whetherWhether3.Were worried about _ he is safe.4.I dont know _ he is well or not.5.I dont know _ or not he is well.whetherwhether/ifwhether6.The question is _ h

14、e should do it.7.The doctor can hardly answer the question _ the old man will recover soon.8.I dont know _ to go.whetherwhetherwhether其它连接代词和副词的连用主要根据名词性从句中的具体意义，正确的选择who/which/when/where/why/how 等连接词，这些连接词既具有_，又起_，同时在从句中充当_。疑问含义连接作用各种成分我们何时举行运动会还没有决定。_ we shall hold our sports meeting is not decide

15、d.我不知道昨天谁打破了玻璃。I dont know _ broke the glass yesterday.Whenwho我不知道他长的什么样子。I have no idea _ he looks like.这就是我忘记眼镜的地方。This is _ I left my glasses.whatwhere引导词 that 的省略1.that引导主语从句，并且主语从句_，由it 作形式主语时，that _；2.that 引导宾语从句时，可以省略；但如果有两个that 引导的宾语从句，则第二个宾语从句中的that _；后置不可省略不可省略3.介词后的宾语从句中的that_;4.如果that 连接

16、的宾语从句中紧接着一个由其他连词引导的状语从句，that _省略；5.引导同位语从句的连词that 在句中_成分，且_省略。不可省略不能不充当不可下列名词性从句中的that是否可以省略。1.It was reported that the football team was warmly received by the Queen.2.I dont believe that he has ever read any of Shakespeares works or that he has ever heard of him.3.His composition is very good exce

19、从句的时态呼应1.如果主句时态是现在时或将来时，从2.句谓语可根据句意需要而选用任何一种时态。3.a.他相信他的梦想总有一天会实现的。He believes _4._.his dream will come true some dayb.请告诉我你昨天这个时候在干什么。Please tell me _ _.what you were doing at this time yesterday2.如果主句谓语是过去时，从句谓语动词用一般用过去的某种时态，但从句表达的是客观事实、真理、自然规律等时，从句谓语通常用一般现在时。他告诉我他正在为考试做准备。He told me _.他说他已离开家乡十年了
