1、 名词性从句主语从句，表语从句，宾语从句和同位语从句在复合句中的作用相当于名词，因此这四种从句统称为名词性从句。这四种从句与主句间不用逗号。一名词性从句连接词的选用可分为三类：1. that 在名词性从句中只起连接作用，不充当成分，也没有实际意义。That he will come is certain.I think that hell be all right in a few days.The fact is that I have never been there.The fact that she had not said anything surprised all of us.2
2、. whether/if 在名词性从句中有“是否”之意，但不充当成分。附Whether/if 区分：在宾语从句中可互换，但介词和 discuss 后的宾语从句用 whether; 其它名词性从句用 whether；可以说 whether to do 但不能说 if to do ;可说 whether / ifor not, whether or not ，不能说 if or not.Whether shes coming or not doesnt matter too much.I wonder whether/ if it is true.The question is whether i
3、t is worth doing.They asked me the question whether the work was worth doing.I dont know whether or not they will come.(不能用 if or not)I dont know if / whether they will come or not.另外别忘了 if 可引导条件状语从句。试比较：Please let me know if you want to go.Please let me know whether you want to go.3. 其它连接词的选用遵循：“缺什
4、么，补什么”的原则。缺状语，补连接副词 where, when, why, how; 缺主语，宾语，表语，定语，补连接代词：who, whom, what, which, whose.Where she has gone is not known yet.Why he did it wasnt quite clear.How he became a great scientist is known to us all.I dont know where we are going to have the meeting. Please tell me when we shall discuss
5、our work plan.This is why he is late.I have no idea when he will come back.I really dont know what he is doing.Which side will win is not clear.That is what he is worried about.Do you know who/whom they are waiting for.He asked whose dictionary it was.二名词性从句应该注意的。1. 名词性从句用陈述语序。注意 what is the matter
6、with.被看作陈述语序。如：Do you know what is the matter with him? 不能用 Do you know what the matter is with him?2. 同位语从句和定语从句的区分：同位语从句对其前边的名词起解释补充说明,可译为 “既;那就是”;定语从句对先行词起修饰限制作用,译为 “的”;that 引导的定语从句在从句中要充当成分,作宾语,表语可省略;而 that 引导的同位语从句只起引导作用,不充当成分 ,不能省略.The suggestion (that )our teacher gave us sounds OK.The sugges
7、tion that we should arrange our time scientifically sounds OK.The news (that) you heard is not true.The news that Lincoln was murdered at a theatre is true.The fact that you pointed out made me interested .The fact that there are no lives on the moon is known to us all. 3. 名词性从句中的 what 可改为定语从句 the t
8、hing(s)/ person(s) that; whatever 可改为 anything that, whoever 可改为 anyone whoThey are careful about what they eat.=They are careful about the things that they eat.He is not what he used to be .=He is not the one that he used to be.He would believe whatever I said.= He would believe anything that I sai
9、d.Whoever leaves the room last should turn off the light.= Anyone who leaves the room last should turn off the light.4. wh-ever 和 no matter wh- 区分：引导让步状语从句，wh-ever 可换为no matter wh-, 引导名词性从句则不能。如：Whatever I said , he wouldnt listen to me.= No matter what I said , he wouldnt listen to me.5. 名词性从句中 tha
10、t 的省略：宾语从句中的 that 可以省略，但并列的宾语从句只有第一个从句的 that 可以省略，第二个从句和第二个以后的 that 不能省；it 作形式宾语的宾语从句 that 不能省; 介词后的宾语从句的 that 不能省；表语从句中的 that 和 it 作形式主语的主语从句的that 在口语中偶有省略。同位语从句中的 that 不能省略。6. reason 或 cause 作主语以及 why 引导的主语从句作主语，其后的表语从句连接词不用 because，常用 that，而且 since 和 as 不能引导表语从句。Why farmland here is being lost is
11、 that farmers have cut down too many trees in recent years.The reason for his being absence from the conference was that he was delayed by the accident.7. 宾语从句：be+ sure / certain /glad / pleased / satisfied / surprised 等也可接宾语从句。Im not sure what I should do.Im afraid you dont understand what I said.宾
12、语从句否定的转移：主句的主语是一人称，谓语是think、believe 、suppose、 expect、imagine 等，对从句的否定习惯上要转移到主句上，并且其反义疑问句要和从句保持一致。I dont think you are right, are you?I dont believe they have finished their work yet, have they?宾语从句后有宾语补足语要用 it 作形式宾语。He has made it clear that he will not give in.8. 注意 it 作形式主语的主语从句和强调句的区分。练习1.
