That he will come is ce

4、rtain。 2. I know that he will come.3。 The truth is that I have been there. 4. The fact that she was late surprised us.二. 名词性从句连接词的用法 LV21。 主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how,when，where，why等词引导。（1)that在句中无词义，只起连接作用；（2)连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如：W

5、hat he wants to tell us is not clear. Who will win the match is still unknown. It is known to us how he became a writer。 Where the English evening will be held has not yet been announced。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用一般过去时或现在完成时的形式。常用句型如下：It + be+名词+that从句It is a surpr

6、ise thatIt is a fact that Its a great pity that they didnt get married。It + be +形容词+ that从句It is necessary thatIt is important thatIts splendid that you passed your exam.It + be +动词的过去分词+ that从句It is believed thatIt is known to all thatIts said that he has been there many times.It +不及物动词+ that从句It a

7、ppears thatIt happens thatIt occurred to me thatIt happened that a doctor was on the train at that very moment.另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“should+动词原形”，常用的句型有:It is necessary (important， natural, strange， etc。) that It is a pity (a shame, no wonder, etc.) thatIt is suggested （requeste

8、d， proposed， desired， etc。) that3 M【小试牛刀】1. It is immediately clear _ the financial crisis will soon be over.2._ was most important to her, she told me， was her family.3. It is obvious to the students _ they should get well prepared for their future.2. 宾语从句引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词

9、及非谓语动词的宾语。由连接词that引导的宾语从句例如：He has told me that he will go to Shanghai tomorrow. We must never think (that） we are good in everything while others are good in nothing. 注意：在demand，order，suggest，decide，insist，desire，request，command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“should+动词原形”。例如:I insist that she （should)

10、 do her work alone. The commander ordered that troops （should) set off at once. 用who，whom, which， whose， what， when, where， why， how, whoever， whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序.例如：I want to know what he has told you. She always thinks of how she can work well。 She will give whoeve

11、r needs help a warm support。 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序.此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：（1）引导主语从句时;Whether there is life on the moon is an interesting question。 （2）引导表语从句时；The question is whether she should have a low opinion of the test?（3)引导宾语从句时;Everything depends

12、 on whether we have enough money。 （4）从句中有“or not”时；I wonder whether he will come or not。 （5）后接动词不定式时。Can you tell me whether to go or to stay？ 注意宾语从句中的时态呼应。例如：He studies English every day. He studied English last term。 I know (that） he will study English next year。 he has studied English since 1998.

13、 当主句动词是过去时态（could， would除外），从句则要用相应的过去时态，如一般过去时，过去进行时,过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：The teacher told us that Tom had left us for Americathink, believe， imagine， suppose等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式.即将从句中的否定形式移到主句中。例如：We dont think you are here. I dont believe he will do so. 3 M【小试牛刀】1。

14、The companies are working together to create _ they hope will be the best means of transport in the 21st century。2。 Could I speak to _is in charge of International Sales please？3。 The old man was so angry and spoke so fast that none of his children understood_ he said meant3。 表语从句引导表语从句的关联词与引导主语从句的关

15、联词大致一样,表语从句位于系动词后，有时用as if引导。其基本结构为:It looks as if。例如：The fact is that we have lost the game。 Thats just what I want. This is where our problem lies. That is why he didnt come to the meeting。 It looks as if it is going to rain. 注意：The reason why he was late was that he missed the train by one minute

16、 this morning.5 M【小试牛刀】1。 The little girl who got lost decided to remain _she was and wait for her mother.2。 The last time we had great fun was _we were visiting the Water Park.3. What makes the school famous is _many students in this school have been admitted to famous universities。4. 同位语从句同位语从句通常由

17、that引导，可用于同位语从句的名词有advice，demand，doubt，fact,hope，idea，information，message,news，order，problem，promise,question，request，suggestion，truth，wish，word等。例如：The news that we won the game is exciting。 I have no idea when he will come back home. The thought came to him that Mary had probably fallen ill。 3 M【小

19、根据五大基本句型（主谓、主谓宾、主谓宾宾、主谓宾宾从、主系表）分析从句是否缺成分3补充正确的连接词LV3掌握名词性从句的引导词从属连词 that， whether， if连接代词（兼名词性)what, who， whom, which, wh+ever连接副词（兼副词性）when, where， how, why3 M【小试牛刀】1.

21、d to me yesterday。名词性从句，主语从句、宾语从句、表语从句和同位语从句在句中做主语、宾语、表语、同位语的成分。I dont know who she is。（宾语）This is why I came here.（表语）区别：第一，定语从句有先行词,且先行词可以放入后面的从句中使从句完整；名词性从句中的主语从句、表语从句和宾语从句没有先行词，同位语从句有先行词但在从句中不做成分。The news that they told me excited me。（the news可以放入从句中，使句子完整，即they told me the news）The news that ou

22、r team won excited me。（the news无法放入从句中,所以是同位语从句）区别：第一，定语从句有先行词，且先行词可以放入后面的从句中使从句完整；名词性从句中的主语从句、表语从句和宾语从句没有先行词，同位语从句有先行词但在从句中不做成分。The news that they told me excited me。 (the news可以放入从句中，使句子完整,即they told me the news） The news that our team won excited me。(the news无法放入从句中，所以是同位语从句）3 M【小试牛刀】1。 She and h
