1、1主语从句主语从句(Subject Clause)定义:在复合句中充当主语的句子叫做主语从句.第一部分：常规主语从句，即句子在复合句中充当一个主语主语从句的时态：不受主句的时态影响和限制。（1）That he finished writing the composition in such a short time surprised us all.（2）Whether we will go for an outing tomorrow remains unknown.（3）Who will be our monitor hasnt been decided yet.（4） Whom we m
2、ust study for is a question of great importance.（5）What caused the accident remains unknown.（6）Whatever you did is right.（7）Whose watch was lost is unknown.（8）What we need is time.（9）What we need are good doctors.小结:（1) 引导主语从句连词有 that,whether,who,what,whatever 等（2) 连词位于句首不能省略（3) 主语从句大多数情况下视为三单,但也有例外
3、,如例 9第二部分：为了防止句子头重脚轻，通常把形式主语 it 放在主语位置，真正主语搁置于句末（1）It is certain that he will win the match.（2）It is true that he has made a very important discovery in chemistry.（3）It is very likely that they will hold a meeting.（4）It is strange that he should do that.（5）It is important that we all should attend t
4、he meeting.（6）It is strange that the man should have stuck to his silly ideas.（7）It is a pity that we wont be able to go to the south to spend our summer vacation.（8）It is still a mystery what caused the accident. （9）It is said that he has gone to shanghai.(=He is said to have gone to shanghai) （10）
5、It is known to all that the gun powder was first invented by the Chinese. （11）It is suggested that the work should be done with great care.（12）It seems that he has seen the film.(=He seems to have seen the film)（13）It happened that the two cheats were there. (=The two cheats happened to be there)小结:
6、（1) 以 that 引出的主语从句,常以形式主语 it 引导. It is +形容词/名词/ 某些动词 ed + that 从句.（2) 在有些 that 从句中要用虚拟语气 (should+do/should+have done)例句4,5,6,11. 一主语从句 主语从句 定义:在句子中担当主语的是一个从句,这个从句就叫做主语从句。 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语 it 代替，而本身放在句子末尾。 1. It 作形式主语和 it 引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而 it 引导的强调
7、句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词 that。被强调部分指人是也可用 who/whom。例如： It is a pity that you didnt go to see the film. 2. 用 it 作形式主语的结构 (1) It is 名词从句 It is a fact that 事实是 It is an honor that 非常荣幸 It is common knowledge that 是常识 (2) it is 形容词从句 It is natural that 很自然 It is strange that 奇怪的是 (3) it 不及物动词从句 I
8、t seems that 似乎 It happened that 碰巧 (4) it is 过去分词从句 It is reported that 据报道 It has been proved that 已证实 3. 主语从句不可位于句首的五种情况 (1) if 引导的主语从句不可居于复合句句首。 (2) It is said , (reported) 结构中的主语从句不可提前。例如： It is said that President Jingo will visit our school next week. 2(3) It happens, It occurs 结构中的主语从句不可提前。例
9、如： It occurred to him that he failed in the examination. (4) It doesnt matter how/whether 结构中的主语从句不可提前。例如： It doesnt matter whether he is wrong or not. (5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如： Is it likely that it will rain in the evening? 4. What 与 that 在引导主语从句时的区别 What 引导主语从句时在句时在从句中充当句子成分，如主语宾语表语，而 that 则
10、不然。例如： What you said yesterday is right. 名词性从句及完形填空1、It doesnt matter _ I rest or not.

19、t exhibition interested every one of us.Athat we go Bwhich we should go Cthat we would go Dwe would go名词性从句包括表语从句、宾语从句、主语从句和同位语从句.其关联词有 that, if , whether, who, what, which, when, where, why 等。一、对表语从句的考查考例 1 - Are you still thinking about yesterdays game? -Oh, thats_ . (2003 北京春季)A. what makes me fe
20、el excited B. whatever I feel excited about C. how I feel about it D. when I feel excited 解析:上文的关键词语“still thinking about yesterdays game“决定必然用表语从句 what makes me feel excited ,表示比赛留下久久不能忘怀的印象 ,豪情激发,现在还在 thinking;B 项是泛泛而指,当然不行;C 和 D 项内容与上下文问题无关。故答案为 A.考例 2-I drove to Zhuhai for the air show last week
21、.-Is that_ you had a few days off?(NMET1999)A.why B.when C.what D.where 解析:这是一个由 why 引导的表语从句,表示原因.这句话的意思是“这就是你离开的原因吗?“ 。故答案为 A。考例 3Perseverance is a kind of quality and thats_ it takes to do anything well.( 2002 上海春季)A. what B. that C. which D. why 解析:what 在表语从句中作 takes 的宾语,构成 “It takes sth. to do s
22、th.“的句型。答案为 A。二、对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语.如果主句的谓语动词是及物动词make, find, see, hear 等,则把宾语从句置于宾语补足语之后, 用 it 作形式宾语. 另外,某些作表语的形容词,如 sure, happy, glad, certain 等之后也可以带宾语从句。考例 4Mr. Hall understands that_maths has always been easy for him, it is not easy for the students. ( 2003 安徽春季)A. unless B. since C. al
23、though D. when 解析:该题考查连词在宾语从句中的用法.观察题干 Mr. Hall understands 是主句,其后有 that 引导的宾语从句,可将该句简化为: _maths has always been easy for him,it is not easy for the students.分析简化后的句子可知,4maths has always been easy for him 与 it is not easy for the students 之间含有转折关系,其他选项不合题干逻辑。故答案为 C。考例 5When you answer questions in a
24、 job interview, please remember the golden rule: Always give the monkey exactly_ he wants .(2002 上海春季)A.what B.which C.when D.that 解析:这是一个宾语从句,wants 后面缺少宾语,Always give the monkey exactly what he wants 是一句谚语,意思是“ 永远给予他人他确实想要的东西“。故答案为 A。三、对主语从句的考查主语从句在从句中作主语,它可以放在主句谓语动词之前 ,但多数情况下由 it 作形式主语,而把主语从句放在主句之
25、后。考例 6_fashion differs from country to country may reflect the cultural differences from one aspect.(2002 上海春季)A.What B.That C.This D.Which 解析:这是含有一个主语从句的句子。因为主语从句是一个完整的句子, 所以要填写 that。这句话的意思是“国与国之间的时装差异可以从一个方面反映出其文化的差异“。答案为 B。考例 7_ she couldnt understand was_ fewer and fewer students showed interest
26、 in her lessons.( 2000 上海)A.What;why B.That; what C.What; because D.Why; that 解析:答案为 A。主语从句 she couldnt understand 缺少宾语,要用 what 引导。表语从句 fewer and fewer students showed interest in her lessons 是一个完整的句子,要用 why 引导,意思是“ 为什么越来越少的学生对她的课感兴趣。“四、对同位语从句的考查同位语从句一般跟在某些抽象名词概念的名词后面,用以说明名词所表示的具体内容,常跟同位语从句的名词主要有:id
27、ea, news, promise, answer, belief, condition, doubt, fear, hope, problem, proof, question, reply, report, suggestion, thought, truth 等。考例 8Information has been put forward_ more middle school graduates will be admitted into universities.( 2001 上海)A.while B.that C.when D.as 解析:that 引导从句作 information
28、的同位语,解释 information 的具体内容.这句话的意思是“有消息说, 有更多的中学毕业生将进入大学“。由于 information 与同位语从句被 has been put forward 分隔开来,增加了试题的难度。巩固练习51.Go and get your coat.Its_you left it.A.there B.where C.there were D.where there 2._he said at the meeting astonished everybody present.A.What B.That C.The fact D.The manner3._ the
