第一篇：复合句(定语从句、名词性从句、状语从句)教案
复合句（定语从句、名词性从句、状语从句）
定语从句
考点一 关系代词引导的定语从句
1．whose是一个表示所属关系的词，在定语从句中作定语，of which可以代替whose指物，词序一般是名词＋of which或of which＋名词。of whom 可以代替whose指人，词序是名词＋of whom。
2．which，that所代替的先行词是表示事物的名词或代词，在从句中可作主语、宾语等。先行词既有人又有物时，关系代词用that；which代指前面整个句子内容。
3．who，whom，that这些词代替的先行词是表示人的名词或代词，在从句中可作主语、宾语等。
考点二 介词提前了的定语从句
1．与定语从句中的动词构成搭配。2．与定语从句所修饰的先行词构成搭配。
3．of＋which/whom表示所属关系。(表所属关系也可用whose)考点三 关系副词引导的定语从句
1．关系副词在定语从句中作状语，when指时间，where指地点，why指原因，在定语从句中分别作时间状语、地点状语和原因状语。
2．先行词是时间名词或地点名词时，如果在从句中不作状语，则不能用when或where引导定语从句，而要用which/that。
考点四 先行词为point, situation, case等的定语从句
point，situation，case，activity等，从表面上看它们不是表地点的，但却表示类似地点的意义，因此它们作先行词时，如果引导词在从句中作状语，那么这个引导词要用where；如果不作状语，则用关系代词that/which。
名词性从句
考点一 主语从句
主语从句在主句中作主语，位于主句谓语动词之前，但多数情况下由it作形式主语，而把真正的主语放在句子的后面，其句型结构为：It＋be＋n./adj.＋that/whether/why/when＋从句。考点二 同位语从句
1．同位语从句常放在fact，news，idea，truth，hope，problem，information，belief，thought，doubt 等名词的后面，是对前面的名词作进一步的解释，说明前面名词的具体含义。2．同位语从句与定语从句的区别：
同位语从句是对前面名词的内容作进一步的解释、说明，引导词只起引导作用，不在句中作任何成分，一般不可省略。定语从句是对前面名词进行修饰、限制，引导词在句中作一定的句子成分。考点三 表语从句
表语从句在句中作表语，位于主句的系动词之后。引导表语从句的连词有that，whether，as if；疑问代词有who，what，which；疑问副词where，why，when，how等。考点四 “疑问词＋ever”与“no matter＋疑问词”的区别
“疑问词＋ever”与“no matter＋疑问词”虽然都有“无论……”的意思，但是用法有区别：“疑问词＋ever”既可以引导名词性从句也可引导状语从句，而“no matter＋疑问词只能用来引导状语从句。
状语从句
考点一 时间状语从句
1．表示时间的状语从句可以由when，whenever，as，while，before，until，ever since，as soon as等词引导。
【温馨提示】when可表原因，意为“既然”。
How can you expect to learn anything when you never listen? 既然你什么也听不下去你怎么期望学东西呢？
2．as soon as，immediately，directly，instantly，the moment，the minute，the instant，no sooner...than...，hardly/scarcely...when...和once(一……就……)这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一……就……”。从句中用一般时态代替将来时态。
3．no sooner...than和hardly...when引导的从句表示“刚……就……”。主句中的动词一般用过去完成时，从句用过去时。若把no sooner, hardly提到句首，主句须倒装。考点二 条件状语从句
1．通常由if，unless如果不，除非，as(so)long as 只要，in case “结果，万一”等连词引导。2．由on condition(that)；provided(that)；providing(that)(假若；倘使)；supposing(that)等引导的条件状语从句。考点三 地点状语从句
1．通常由连词where和wherever引导，从句可位于主句之前，也可位于主句之后。2．地点状语从句在句首时常兼有抽象条件意味。Where there's a will，there's a way.有志者事竟成。考点四 让步状语从句
1.由although，though，as引导的状语从句although和though同义，用法基本相同。前者较正式，多置于句首；后者较通俗、口语化。
【温馨提示】 as引导的让步状语从句多用于书面语，语序要倒装。Child as he is, he knows a lot.尽管他是个孩子，但是他知道得很多。
2．even if, even though表示“即使，纵然”，有退一步设想的意味，多用于书面语中。3．whether(...or)引导让步状语从句，提供两个或两个以上的假设。4．由疑问词＋ever引导让步状语从句。考点五 原因状语从句
原因状语从句常用because, since, as, for引导，还可用now that(既然)，considering that...(考虑到……)，not that...but that(不是因为……而是因为)等引导。考点六 结果状语从句
结果状语从句由so that, so...that, such that, such...that等词引导。
复合句专项练习
1.The school shop, ________ customers are mainly students，is closed for the holidays.A.which
B.whose
C.when
D.where 【解析】答案：B 句意：这家校内商店放假时关门，它的顾客主要是学生。考查定语从句。本句没有并列连词也没有从属连词，故可判断逗号后面是非限制性定语从句；本句先行词是the school shop，还原到从句后为：The school shop’s customers are mainly students.因此选B，用whose引导定语从句，关系代词whose在从句中作定语。
2.The old town has narrow streets and small houses ________ are built close to each other.A.they
B.where
C.what
D.that 【解析】答案：D 句意：这个古老的小镇拥有建造得彼此靠得很近的狭窄街道和小房子。本题考查定语从句。先行词是narrow streets and small houses，还原到从句中作主语，所以用关系代词that。A和C不能引导定语从句；B是关系副词，不能作主语。3.Julie was good at German, French and Russian, all of ________ she spoke fluently.A.who
B.whom
C.which
D.that 【解析】答案：C 句意：Julie擅长德语、法语和俄语，所有的(三门语言)她都说得很流利。先行词为German，French，Russian，代入定语从句后为：She spoke all of the three languages fluently.由此可见，先行词在定语从句中作of的宾语，先行词指“物”，且介词提前，故用which。4.Mother bought many tomatoes from the market two days ago, ________ some have gone bad due to the bad weather.A.of those
B.from which
C.of which
D.in which 【解析】答案：C 考查定语从句。此处表示“其中的一些西红柿”，故用“介词＋关系代词”引导非限制性定语从句。
5.As a teacher, I seldom give my students so difficult a problem ________ they cannot work out.A.that
B.if
C.in order that
D.as 【解析】 答案：D 句意：作为老师，我很少给我的学生难以解决的问题。先行词为so difficult a problem，代入定语从句后为：They cannot work out so difficult a problem.由此可见先行词在定语从句中作宾语。“so或such＋名词”作先行词、且先行词在定语从句中作主语、宾语或表语时，需用as引导定语从句。本题易误选为A项，用that引导状语从句，但状语从句应是完整的，所以，如选A项，题干应该为：As a teacher，I seldom give my students so difficult a problem that they cannot work it out.作为老师，我很少给我的学生如此难的问题以至他们不能解决。
6.It is still under discussion ___ the old bus station should be replaced with a modern hotel or not.A.whether
B.when
C.which
D.where 【解析】答案：A 本题考查名词性从句。句意：那个旧公交车站是否应该被一家现代化宾馆所取代仍在讨论中。“It”作形式主语，“________ the old bus station should be replaced with a modern hotel or not”作真正的主语。根据句意及题干中的“or not”可知答案为whether，“whether...or not”在名词性从句中意为：是否。
7.She is very dear to us.We have been prepared to do ________ it takes to save her life.A.whichever
B.however
C.whatever
D.whoever 【解析】答案：C 句意：她对我们弥足珍贵。我们已经准备好尽一切努力挽救她的生命。这里的whatever既作take的宾语，也引导do后的宾语从句。
8.Being angry is OK, but knowing how to tell someone ________ made you angry is important.A.that
B.which
C.why
D.what 【解析】答案：D 考查名词性从句。句意：生气没什么，但是知道如何告诉别人什么导致你生气是很重要的。tell someone之后是宾语从句，且从句缺少主语，因此空处填what。9.In recent years, there has been a heated argument about ________ it is necessary for children to learn English from an early age.A.whether
B.if
C.what
D.that 【解析】答案：A 考查宾语从句。空白处在介词about之后，表示“是否”之意，且在介词之后引导宾语从句，只能用whether，介词后通常不用if引导宾语从句。
10.The whole family were worried about Jane because no one was aware ________ she had gone.A.that where
B.of the place which
C.of what
D.of where 【解析】答案：D 句意：全家人都为詹妮担心，因为没人知道她去哪里了。be aware of知道，为固定搭配；where引导的从句作介词of的宾语。
11.He had no sooner finished his speech ________ the students started cheering.A.since
B.as
C.when
D.than 【解析】答案：D 本题考查固定句式。句意：他刚做完演讲，学生们就开始欢呼起来。no sooner往往与than连用，意为：一……就……。故答案为D项。
12.As is reported, it is 100 years ________ Qinghua University was founded.A.when
B.before
C.after
D.since 【解析】答案：D 考查状语从句。句意：据报道，自从清华大学成立已经有100年了。这里用句式“It be＋一段时间＋since引导的状语从句”表示“自从……(到现在)有多长时间了”。
13.No matter how ________, it is not necessarily lifeless.A.a desert may be dry
B.dry a desert may be C.may a desert be dry
D.dry may a desert be 【解析】答案：B 本题考查让步状语从句。句意：无论沙漠可能会多么干燥，那里也未必没有生命。“no matter how＋形容词/副词＋主语＋谓语”构成让步状语从句。四个选项中只有B项符合要求。
14.Having checked everything, he sat down to do his homework, ________ he heard a lightening strike the electricity pole in the backyard.A.for
B.when
C.or
D.but 【解析】答案：B 考查连词。句意：检查了所有的东西之后，他坐下来开始写作业，这时他听到闪电击中了后院的电线杆的声音。此处用when表示“这时”。
15.If you are traveling __ the customs are really foreign to your own, please do as the Romans do.A.in which
B.what
C.when
D.where 【解析】答案：D 句意：如果你正在一个风俗迥异的地方旅行，请入乡随俗。where引导地点状语从句；A项in which在定语从句的引导词，缺少先行词，所以不正确。16.--Could you please cut the price a little?--Er...________ you buy more than ten.A.even if
B.so long as
C.in case
D.as soon as 【解析】答案：B 句意：— 你能降一点价吗？— 呃……只要你买十个以上。so long as只要；even if即便，即使；in case以防万一；as soon as一……就……。
17.It was foolish of you to take a taxi ________ you could easily walk there in five minutes.A.though
B.as long as
C.so that
D.when 【解析】答案：D 考查连词。句意：你五分钟就可以走到那儿的，可你还打的去，真是太傻了。根据语意可知此处用when引导状语从句，意为“既然，考虑到”。though意为“尽管，虽然”；as long as意为“只要”；so that意为“为了”，都不符合题意。18.________ one is fully prepared, out door sports can sometimes mean injuries.A.Until
B.Because
C.When
D.Unless 【解析】答案：D 考查连词辨析。句意：要是没有充分准备的话，户外运动有时会意味着受伤。根据语意选D项，表示“如果不……；除非……”。
19.There she was, standing exactly ________ I had left her, crying bitterly.A.when
B.that
C.where
D.in which 5 【解析】答案：C 考查状语从句。句意：她就站在我刚才离开她的那个地方悲痛地哭。where I had left her是地点状语从句。
20.The new teacher was so well organized that she began ________ we stopped yesterday so that no point was left out.A.when
B.in which
C.how
D.where 【解析】答案：D 考查状语从句。句意：这位新老师条理非常清楚，她从我们昨天停止的地方开始，没有遗漏要点。where we stopped yesterday是状语从句。21.--Could you do me a favour?
--It depends on ________ it is.A.which
B.whichever
C.what
D.whatever 【解析】答案：C what在此导宾语从句，what在宾语从句中用作表语，句意为：这要看是什么(即这要看你要我帮什么忙)。
22.________ team wins on Saturday will go through to the national championships.A.No matter what
B.No matter which
C.Whatever
D.whichever 【解析】答案：D 从句意上看，应一个表示“无论哪一个”的选项，因此B和D比较合适，但No matter which只用于引导状语从句，不用于引导名词性从句，故不能选B。23.--It’s thirty years since we last met.--But I still remember the story, believe it or not, ________ we got lost on a rainy night.A.which
B.that
C.what
D.when 【解析】答案：B that在此引导同位=语从句，修饰名词the story。此题的难点是，其中插入了believe it or not，使问题变得复杂了。
24.See the flags on top of the building? That was ________ we did this morning.A.when
B.which
C.where
D.what 【解析】答案：D what在此引导表语从句，同时what在表语从句中用作动词did的宾语，其意相当于did the thing that。
25.A warm thought suddenly came to me ________ I might use the pocket money to buy some flowers for my mother’s birthday.A.if
B.when
C.that
D.which 【解析】答案：C that在此引导同位语从句，修饰名词thought。此题的难点是，名词thought与修饰它的同位语从句被分离开了。
26.The factory was built in a secret place, around ______ high mountains.6 A.which was
B.it was
C.which were
D.them were
【解析】答案：C 容易误选A 或B, 将A、B 中的 which和 it 误认为是其后句子的主语。around which were high mountains是一个由 “介词+which” 引出的非限制性定语从句，而在该从句中，主语是 high mountains, around which是表语，所以句子谓语应用复数were，而不是用单数 was。
请做下面一组题（答案均为C）：
（1）Yesterday we visited a modern hospital, around _______ some fruit shops.A.which is
B.it is
C.which are
D.them are（2）The murder happened in an old building, beside ______ the city police station.A.which are
B.it is
C.which is
D.them are（3）Next month we’ll move to a new building, next to _______ a nice restaurant where we can have Chinese food.A.which are
B.it is
C.which is
D.them are 27.A man with a bleeding hand hurried in and asked, “Is there a hospital around ______ I can get some medicine for my wounded hand?”
A.that
B.which
C.where
D.what
【解析】答案：C 容易误选 B，认为around 是介词，选which用以代替前面的名词hospital, 在此用作介词 around 的宾语。以上语法分析并不算错，但问题是，照此分析，此句的意思即为：有没有这样一个医院，我在它的附近可以买药治我的手伤？这样的语境显然有点不合情理，因为人们通常是在医院里面治伤，而不是在医院附近治伤。此题选 C的理由是：句中的 around 不是介词，而是副词, 意为 “在附近”；其后的 where引导定语从句用以修饰其前的地点名词 hospital, 句意为：附近有没有一家医院，我可以去买药治我的手伤？ 28._____ is known to everybody, the moon travels round the earth once every month.A.It
B.As
C.That
D.What
【解析】答案：B 容易误选 A，认为此处应填一个形式主语。as 引导的是一个非限制性定语从句。比较下面一题：
_______ is known to everybody that the moon travels round the earth once every month.A.It
B.As
C.That
D.What
此题答案选 A，it为形式主语，真正的主语是后面的 that 从句。再比较下面一组题，其中第（1）题选 B，第（2）题选 D：
7（1）______ is mentioned above, the number of the students in senior school is increasing.A.Which
B.As
C.That
D.It（2）______ is mentioned above that the number of the students in senior school is increasing.A.Which
B.As
C.That
D.It 29.Our company will move to a tall building _______ has just been complete.A.which
B.when
C.how
D.where 【解析】答案：A which 在定语从句中用作主语。
30.Our company will move to a tall building _______ we worked two years ago.A.where
B.when
C.that
D.which 【解析】答案：A where 在定语从句中用作状语。
附加题
1.David is such a good boy _______ all the teachers like.A.that
B.who
C.as
D.whom 【陷阱】此题容易误选A，许多同学一看到题干中的such，再联系到选项中的 that，便认为这是考查such…… that ……句式。况且，这样理解意思也还通顺。最佳答案为C, 不是A, 因为在such…… that ……（如此……以至……）结构中，that引导的是结果状语从句，并且 that 在从句中不充当句子成分，若在上句填入 such …… that ……，句末的动词 like 缺宾语。选C 的理由如下：as用作关系代词，用以引导定语从句，修饰其前的名词 boy，同时 as在定语从句中用作动词 like 的宾语，句意为 “所有老师都喜欢的一位好男孩”。有的同学可能还会问，假若选A, 能否将其后的 that 视为引导定语从句的关系代词呢？不能，因为当先行词受到 such 的修饰时，其后的定语从句应用关系代词 as 来引导，而不用that。比较下面一题，答案为A, 因为 like 后有自己的宾语 him。David is such a good boy _______ all the teachers like him.A.that
B.who
C.as
D.whom 请再做以下试题（答案选D）：
It was not such a good dinner _______ she had promised us.A.like
B.that
C.which
D.as 2.The buses, most of _______ were already full, were surrounded by an angry crowd.A.that
B.it
C.them
D.which
【陷阱】容易误选 C, 用 them 代指 the buses。最佳答案是D。most of which were already full为非限制性定语从句，修饰 the buses。类似地，以下各题也选D。
8（1）His house, for _______ he paid $10, 000, is now worth $50, 000.A.that
B.it
C.them
D.which（2）Ashdown forest, through _______ we’ll be driving, isn’t a forest any longer.A.that
B.it
C.them
D.which
（3）This I did at nine o’clock, after _______ I sat reading the paper.A.that
B.it
C.them
D.which 类似地, 以下各题选 whom, 不选 them:（4）George, with _______ I played tennis on Sundays, was a warm-hearted person.A.that
B.him
C.them
D.whom
（5）Her sons, both of ______ work abroad, will come back home this summer.A.that
B.who
C.them
D.whom（6）I met the fruit-pickers, several of _______ were still university students.A.that
B.who
C.them
D.whom 3.He had thousands of students, many of ______ gained great success in their own field.A.whom
B.them
C.which
D.who
【陷阱】容易误选 B，用 them 代指 students。最佳答案是A，many of whom gained great success in their own field为非限制性定语从句。假若在many of ……的前面加上连词and，则选答案B.比较以下各题（答案均选A）:（1）He asked a lot of questions, none of ______ was easy to answer.A.which
B.them
C.what
D.that
（2）He asked a lot of questions, and none of ______ was easy to answer.A.them
B.which
C.what
D.that（3）He told me that he had two girl-friends, neither of _______ knew anything about the other.A.whom
B.them
C.which
D.who（4）He told me that he had two girl-friends, and neither of ____ knew anything about the other.A.them
B.whom
C.which
D.who 4.He had a lot of friends, only a few of ______ invited to his wedding.A.whom
B.them
C.which
D.who
【陷阱】容易误选 A, 认为这是非限制性定语从句。最佳答案是B, 这不是非限制性定语从 句，而是一个独立主格结构，因为空格后的动词 invited并不是一个完整的谓语，而是一个 过去分词。当然，假若在 invited前加上助动词 were, 则是一个非限制性定语从句, 答案
便应选A。比较：
（1）They put forward a lot of plans at the meeting, none of _______ carried out in their work.A.which
B.them
C.what
D.that 答案选B, none of them carried out in their work是独立主格结构，carried out 为过去分词。
（2）They put forward a lot of plans at the meeting, none of _____ were carried out in their work.A.which
B.them
C.what
D.that 答案选A, none of them were carried out in their work 是非限制性定语从句，注意与上例比较 句中多了一个助动词were.（3）They put forward a lot of plans at the meeting, but none of __ were carried out in their work.A.which
B.them
C.what
D.that
答案选B, 由于两句之间增加了一个并列连词but, 使得该句成了一个并列句。
5.On Sundays there were a lot of children playing in the park, ____ parents seated together joking.A.their
B.whose
C.which
D.that 【陷阱】容易误选, 认为这是非限制性定语从句。最佳答案是A。与上面一题相似，their parents seated together joking不是非限制性定语从句，而是一个独立主格结构，因为空格后 的动词seated不是谓语，而是一个过去分词，因为 seat 作动词用时，是及物动词。比较以 下相似题：
（1）On Sundays there were a lot of children playing in the park, _______ parents were seated together joking.A.their
B.whose
C.which
D.that 选B。whose parents were seated together joking 为非限制性定语从句，因为其后有完整的谓语 were seated.（2）On Sundays there were a lot of children playing in the park, and _______ parents were seated together joking.A.their
B.whose
C.which
D.that 选A。因为句中有并列连词and, 整个句子为并列句。
（3）On Sundays there were a lot of children playing in the park, _ parents sitting together joking.A.their
B.whose
C.which
D.that 选A。their parents sitting together joking 为独立主格结构。
（4）On Sundays there were a lot of children playing in the park, ____ parents sat together joking.A.their
B.whose
C.which
D.that 10 选B。whose parents sat together joking 为非限制性定语从句，因为句中有完整的谓语sat。（5）On Sundays there were a lot of children playing in the park, _______ parents were sitting together joking.A.their
B.whose
C.which
D.that 选B。whose parents were sitting together joking为非限制性定语从句，因为句中有完整的谓语 were sitting。
6.If the man is only interested in your looks, _____ just shows how shallow he is.A.as
B.which
C.what
D.that
【陷阱】容易误选A 或B, 认为这是非限制性定语从句。正确答案为D，注意逗号前是一个条件状语从句，逗号后是该状语从句的主句，that在此代表前文所述的情况，用作主句的主语。类似地，下面几道题也选 that, 而不选 which：（1）If you promise to go with us, _____ will be OK.A.as
B.which
C.and it
D.that（2）If you want a double room, _____ will cost another￡15.A.as
B.which
C.what
D.that（3）Whether you go or not, _______ is quite all right with me.A.that
B.which
C.and it
D.so（4）When I say two hours, _____ includes time for eating.A.as
B.which
C.what
D.that 7.She says that she’ll never forget the time _ she’s spent working as a secretary in our company.A.which
B.when
C.how
D.where 【陷阱】容易误选B, 机械地认为时间名词后必须用关系副词when，地点名词后用关系副词 where.正确答案为A.在时间名词和地点名词后是否用关系副词要看它在定语从句中充当什么句子成分。一般说来，若用作主语或宾语，用关系代词；若用作状语，则用关系副词。上面一题中的动词 spent缺宾语，故应用关系代词 which或that。比较下面一组题：（1）She says that she’ll never forget the time _______ she works as a secretary in our company.A.which
B.when
C.how
D.where 选B。由于空格后的句子不缺少主语或宾语，所以选关系副词when。（2）Our company will move to a tall building _______ we bought last month.A.which
B.when
C.how
D.where 选A。which在定语从句中用作动词 bought 的宾语。

第三篇：名词性从句
名词性从句
名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。一．引导名词性从句的连接词
1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。
3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if(whether), as if虽有词义，但在从句中不担任成分。
注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。二.名词性从句的分类如下
（一）主语从句
主语从句的句型.引导词有疑问词wh-及whether/if及that.1、主语从句在复合句作主语。疑问词引导e.g.Who will go is not important.2、用it作形式主语，主语从句放在句末。
3、If/whether 引导e.g.It doesn’t matter so much whether you will come or not.4．It+be+adj(obvious,true,natural,surprising,good,wonderful,funny,likely,certain,probable,etc)/名词词组（no wonder,an honor , a good thing,a pity,etc)+that从句 e.g.It’s certain that she will do well in the exam/It’s no surprise that our team has won the game.5．It+be+过去分词（said,reported,thought,expected,decided,announced,etc)+that从句
e.g.It’s said that Mr.Green has arrived in Beijing.Note:that引导主语从句时，在口语和非正式文体中可以省略，但that从句置于开头时不能省略。e.g.That he suddenly fell ill last week made us surprised.（二）表语从句
表语从句的句型及要点。引导词疑问词wh-及whether及that.1、表语从句在复合句中作表语，位于系动词之后。疑问词引导的： e.g.The question was who could go there.Note: 引导表语从句的连接词that一般不可省去。
e.g.My idea is that we can get more comrades to help in the work.连接词that一般不能省略，但当主句中含动词do的某种形式时，that可以省略。如： What I want to do is(that)I can go up to him and thank him.我想做的事是走到身边去感谢他
（三）宾语从句
宾语从句在复合句中作宾语。引导词有疑问词wh-及whether、if(if 和whether 有区别）及that.引导宾语从句的连词that一般可省略。e.g.I hope(that)everything is all right.Note:以下情况that不可省略：(不考查）
1.当宾语从句的主语是that时。2.2.当宾语从句中含有主从复合句时 Father promised that I studied harder he would take me to Beijing.3.当两个或多个宾语从句由并列连词连接时，除第一个从句中的that可以省略外，其余从句中的that都不可以省略。
4当that偶尔作except和in的宾语时。This book is unsatisfactory in that it lacks a good index.中，that it lacks a good index就是介词 in 的宾语从句，这当中的that就不能省略。
（四）同位语从句。引导词wh-及whether及that.同位语从句引导词有疑问词wh-及whether及that.同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。e.g.I have no idea when he will be back.The fact that he had not said anything surprised everybody.名词性从句易混知识归纳
易混点一 ：同位语从句与定语从句的区别
that引导的从句，是定语从句还是同位语从句，我们我们采用“试加 法”，来判断。The fact that he had not said anything surprised everybody.This is the fact that you must know clearly.1.when、where、why引导的从句
引导定语从句时，其意义与先行词有关，与先行词的意义基本相同，没有疑问意义；但引导同位语从句时，其意义完全与疑问词相同，即when表示什么时候，where表示哪儿，引导两种从句时，都在从句中做状语。如： I still remember the day when I first came to Beijing.句中的when相当于“on the day”它没有疑问词“什么时候”的意义，因此是定语从句。
I have no idea when she will be back.when与idea毫无意义上的关联，其意思是“什么时候”,因而是同位语从句。易混点二：reason后面的名词性从句
reason做主语时，后面的表语从句表示原因是要用that引导，一般不用because或why，而用it，this或that做主语时，后面的表语从句可用because或why引导。
1.“The reason +连系动词+that“引导的表语从句。本句型的意思是：理由是：。。。The reason was that he fell ill.2.It（或This、That）+连系动词+the reason+why引导的定语从句。本句型意为：这就是。。。的原因（理由）That is the reason why he failed in the contest, 3.It（或This、That）+连系动词+the reason+because引导的表语从句。本句型意为：这是因为。。。；这是由于。。。的缘故。That was because he fell ill.4.It（或This、That）+连系动词+why引导的表语从句。本句型意为：这就是。。。的原因。
That was why he fell ill.易混点三：what、whatever、who、whoever等引导的名词性从句 我们可以通过与定语从句的转化知道两组在意义上的差别。Whatever=anything that（无论什么）Whoever=anyone who（无论谁）
Whenever=any time=no matter when（无论何时）Wherever=any place=no matter where（无论何地）这都是泛指。而what、who、when、where则是特指。如： Who spoke at the meeting is unknown The person that spoke at the meeting is unknown.Whoever breaks the law will be punished.Anyone who breaks the law will be punished.注意：1.whatever、whoever、whenever、wherever等常引导主语从句、宾语或表语从句，也可以引导状语从句，等于“no matter +疑问词”。而no matter +疑问词只能引导让步状语从句。Eg：Whatever I said/No matter what I said, he wouldn’t listen to me..2whoever的宾格还是whoever，一般不用whomever。易混点 whether与if（不做考查）
二者都可以作“是否”讲，能引导名词性从句，都不能省略。1.在及物动词后引导宾语从句时可以互换；
注意：在某些动词后（如:discuss）只能接whether，不能跟if。如： We discussed whether we should close the shop.2.引导主语从句、表语从句、同位语从句时都用whether，不用if。如：
The question whether he should come himself or send another man hasn’t been decided.Whether he will win is all the same to me.The question is whether you can go there yourself.但如果主语从句是有It用作形式主语，if和whether都可以 It is unknown whetherif she is ill.3宾语从句中，如果whether后紧跟or not，不用换做if；若whether与or not分开使用，则可以换作if。如： I wonder whether or not he has arrived at the destination.I don’t know whetherif I can come or not.4.若宾语从句为否定结构，则多用if，而不用whether。如： I don’t care if he doesn’t show up.（炫耀）
5.在介词后引导宾语从句或与带to的动词不定式结合而构成不定式的复合结构时，只能用whether，而不用if。如：
I haven’t settled the question of whether I will go back home.She doesn’t know whether to get married now or wait.练习：名词性从句

第四篇：名词性从句教案
名词性从句包括：
主语从句
表语从句
宾语从句
同位语从句
• The question is who can complete the difficult task.• He has no idea what a remarkable woman Mary is.• That she was able to come made us very happy.• He objected that it was impossible.一、主语从句
1、主语从句在复合句中作主句的主语
That she was chosen made us very happy.What caused the accident is a complete mystery.Whoever comes to the party will receive a present.【注】 “that”在主语从句中不作任何成分，但放在句首时不能省略。
2、问：怎么才能 that 不放在句首呢？
答：有时为了使句子结构平衡，避免“头重脚轻”，常用it作形式主语，而把从句放在后面。
It depends on the climate whether they are going shopping today.试试看：新产品销售得好不好取决于它的质量和价格。
It作形式主语的几种结构：
1、It+ be +形容词+ that从句
It is strange that he knows nothing about it.2、It+ be +名词+ that从句
It is a pity that they have failed in the match.3、It+动词+宾语+ that从句
It depends on its quality and price whether a new product sells well.4、It+动词的被动结构+ that从句
It is still unknown which team will win the match.作文常用句式：
1、It turned out that...结果是„
2、It has been proved that...已经证明„
3、It is well-known that...众所周知„
4、It must be pointed out that...必须指出„
二、表语从句
1、表语从句在复合句中作主句的表语
The reason is that you don’t trust her.This is where I disagree.例：The reason ____ we didn't trust him is ______ he has often lied． reason 后面的表语从句只能用that 引导, 不能用because 引导, 但reason后面的定语从句可以用why。
2、表语从句不能用if引导，但可用as if引导。例如： He looked as if he was going to cry.三、宾语从句
宾语从句在复合句中作主句的宾语，宾语从
句一般放在动词、介词或形容词后。
She explained that she was late because of the heavy traffic.【注】
① 有时要用it作形式宾语，而把宾语从句放在句子的后面。He has made it clear that he will not give in.①
如do you think/believe/suppose/expect/imagine后接特殊疑问词引
导的宾语从句，疑问词要放在句首。
What do you think is going on outside? ③
I/We(don’t)think/believe/suppose/expect/imagine后接宾语从句
时，反义疑问句要与从句中的主语和谓语保持一致。
I don’t suppose he cares，does he? ④ 在宾语从句中，引导词whether和if基本一样，但介词后的宾语
从句多用whether。
It all depends upon whether we can get their cooperation.⑤ 动词doubt如用于肯定句，其后的宾语从句常用if/whether引导，如用于否定句或疑问句，则宾语从句用that引导。
I doubt if/whether our football team will win the match.I don’t doubt that I can defeat him in the contest.四、同位语从句
在主从复合句中作同位语的从句称为同位语从句。同位语从句常放在fact, news, idea, truth, hope, problemin, formation 等名词后面，用以说明该名词的具体内容。
The news that they had won the game soon spread over the whole school.
引导同位语从句的关联词用that时，不能省略，不能用which替代
1.引导词that与what的区别
what从句中作句子成分(主语、宾语、表语等)what=all that/everything that that引导的主语从句放在句首时，不能省略
What we can’t get seems better than what we have.That a new teacher will come to teach us geography is true.2.引导词if和whether的区别
whether或if均可表示“是否”的情况如下：
引导宾语从句。例如：
I wonder whether/if the news is true or not. 只能用whether不能用if表示“是否”的情况：
在表语从句中。例如：
The question is whether the film is worth seeing. 在同位语从句中。例如：
The news whether our team has won the match is unknown.Answer my question whether you are coming. 在主语从句中。例如：
Whether we shall attend the meeting hasn’t been decided yet.如果用it作形式主语，则whether和if都能引导主语从句。
例如：It hasn’t been decided whether/if we shall attend the meeting. 用于句型“名词+as to + whether”中。例如：
There is some question as to whether the public should be told about the accident. 后面直接跟动词不定式时。例如：
He doesn’t know whether to stay or not. 后面紧接or not时。例如：
We didn't know whether or not she was ready. 用if会引起歧义时。例如：
Please let me know if you like it.该句有两个意思 “请告诉我你是否喜欢”或 “如果你喜欢，请告 诉我”用了 whether就可以避免歧义。3.引导词who与whoever的区别
whoever引导名词性从句时，相当于anyone who或those who，它
既是从句的主语，又是主句的主语。而who只作从句的主语，它
引导的从句才是主句的主语。
Whoever has helped to save the drowning girl is worth praising.Who will be elected president doesn’t make much difference to me.4.引导词what与whatever的区别
whatever引导名词性从句时，与what差不多，只是语气上更强
些，有“任何一切„„”之意。
This is exactly what I want. It is generally considered unwise to give a child whatever he or she wants.5.同位语从句与定语从句的区别
同位语从句本身完整，定语从句不完整，因此其前的名词在定语从句中通常作主语、宾语或表语等成分。I made a promise that if anyone set me free I would make him very rich.The mother made a promise that pleased all her children.从结构看，同位语从句常由连接词that引导，虽在从句中不充 当任何成分,但不可省略。而定语从句中由关系代词引导，代替先行 词，并在从句中充当成分（主语或宾语），充当宾语时常可省略。6.It 作形式主语和it引导强调句的比较
将 “it is/was„that„”去掉后,句子仍然成立的是强调句,否则是that引导的主语从句 如：
It is a pity that you didn’t go to see the film.It is in the morning that the murder took place.It is John that broke the window.7.whoever与no matter who；whatever与no matter what whoever和whatever既可以引导名词性从句，也可引导让步状语
从句；no matter who和no matter what只引导让步状语从句。Whatever(＝No matter what)you may think，I’m going ahead with my plans.Take whatever you need and leave me alone.9.名词性从句中的语气
(1)在It is necessary/natural/important/strange...＋that从句中，从句中的谓语动词用“should＋原形动词”表虚拟语气，且should 可省略。
It is necessary that the problem should be settled at once.(2)表示“建议、命令、要求”意义的动词，后接that从句时，从句
中的谓语动词要用虚拟语气，即“should＋原形动词”，且should 可省略。
Bob’s doctor suggests that he(should)rest for a few days.(3)表示“建议、要求、命令、想法”意义的名词，后接that从句时，从句中的谓语动词要用虚拟语气：“should＋动词原形”，should可以省略。
这类名词有：advice，agreement，command，decision，demand, determination，order，preference，proposal，request，requirement等。This is our only request that this(should)be settled as soon as possible.同样，如主语是表示“建议、要求、命令、想法”意义的名词，那么that引导的表语从句中也要用虚拟语气。
Her suggestion was that they(should)carry on their conversation in French.

名词性从句学案
一、学习目标
1、本阶段大纲要求
近年来，引导名词性从句的连接代词及连接副词为高考必考项目。此语法项目除单选外，完形，短文改错也考。另外学好它，对阅读理解是大有好处的。名词性从句包括主语从句、宾语从句、表语从句和同位语从句
2、本阶段重点、难点
1表命令建议order,(命令），suggestion, advice(建议)
的名词后的表语从句 2.that.whether的区别 3.What, that, which 4:that 的省略
5: whoever引导的名词性从句 6：because引导的表语从句 7: 名词性从句皆用陈述语序
二、基础知识体系、重点内容、题的类型及解题方法等 基础知识体系
名词性从句的连接词按其在从句中所起的作用分为：
1）连接代词：who(-ever), what(-ever), which(-ever), whom(-ever), whose 2）连接副词：when, where, why, how 3）连接词：that, whether, if 连接代词和连接副词在从句中充当一定的句子成分，而连接词在从句中不充当句子成分，只起连接作用
名词性从句的难点把握
1由whoever/whatever/whichever/whomever引导的名词性从句 这些词引导的名词性从句相当于带有定语从句的名词词组：
whoever=anyone who„“任何„„的人”；whomever是whoever的宾格形式 whatever=anything that„ “任何„„的物”
whichever=any „ that„ “任何„„的（已知范围内的或上文提到过的）人或物” that引导的同位语从句与定语从句的区别：
The suggestion that the students(should)have plenty of exercise is very good.The suggestion(that/which)he raised at the meeting is very good.对比发现上句中的that只起连接作用，在从句中不充当任何成分，因此它引导的是同位语从句，其中that不能省略；下句中that不仅起引导作用，同时在从句中还充当了动词raised的宾语，因此它是定语从句，此时that可用which代替，又因其在定语从句中充当宾语，故又可省略。
2．名词性从句中的what和that what和that的选用一直是学生学习的一个难点，正确选择的关键是看该从句结构是否相对完整、是否缺少主语、宾语或表语等成分而定。he said at the meeting surprised everybody present.That he said nothing at the meeting surprised everybody present.The problem is what we should do to protect the ear What th.The fact is that we should do something to protect the earth.3．名词性从句中的whether和if 在主语从句、表语从句和同位语从句中遇“是否”句用whether引导而不用if；在宾语从句中whether和if常可换用。4．名词性从句中的虚拟语气
表示“坚持、命令、建议或要求”等词义出现时，不管是在哪一种从句中，常用虚拟语气，从句中的谓语动词形式为（should）+ 动词原形，其中should可省略。常用词有insist, suggest, order, demand等。三． 教学步骤。1.复习句型结构。
带领学生复习一下英语当中的五种简单句型结构以及主从复合句和并列句，并分清楚他们之间的区别与联系。
简单句 S + V
He fled.S + V + O
He didn’t invite me.S + V + P
I am a teacher.S + V + Oo
He promised me a bike as my birthday gift.S + V + O + C
I want you to assist me.简单句 + 并列连词
+简单句
→ 并列句
简单句 + 并列连词
+ 主从复合句 → 并列句
2.分辨句子。从以下所给的例题中选出名词性从句并标明是哪种名词性从句。
1.The people invited to the ball may dress __ they please.宾从
A.however
B.whatever
C.wherever
D.whenever 2.I can't quite remember __ you started doing the work.宾从

A.why;because
B.why;that

D.that;that 因高三为复习课，所以在复习完基本句型的基础上作此练习，可以帮助学生进一步去熟悉句型结构，为名词性从句的掌握打下基础。三．做题，讨论，自我总结。
在这一板块，先给学生8分钟时间完成上述题目，之后三人小组讨论进行答案分析，然后老师给出正确答案，并对学生自己无法解决的题目进行讲解。然后，再次进入讨论环节，并进行自我总结，总结出在做名词性从句当中须注意的点。1.连词的选用。1.名词性从句的连接词按其在从句中所起的作用分为：
1）连接代词：who(-ever), what(-ever), which(-ever), whom(-ever), whose 2）连接副词：when, where, why, how 3）连接词：that, whether, if 连接代词和连接副词在从句中充当一定的句子成分，而连接词在从句中不充当句子成分，只起连接作用
2.名词性从句需使用陈述语气。3.连词if和 whether 的区别。
A 在动词不定式之前只能用whether。如：
例8 I can’t decide whether to stay.我不能决定是否留下。
B 在whether …… or not 的固定搭配中。如：
例9 I want to know whether it’s good news or not.我想知道是否是好消息。
C 在介词后，只能用whether。如：
例10 His father is worried about whether he lose his work.他的父亲担心是否会失去工作。
D 宾语从句放在句首表示强调时，只能用whether。如：
例11 Whether they can finish the work on time is still a problem.他们是否能准时完成这项工作还是个问题。
E 用if会引起歧义时，只用whether。如：
例12 Could you tell me if you know the answer ?
5.表命令建议order,(命令），suggestion, advice(建议)
的词后跟的从句使用虚拟语气sb should do, should 可以省略 一主张：insist 二命令：order command 三建议：suggest advise recommend 四命令：desire demand require request 6.that引导的同位语从句与定语从句的区别：
The suggestion that the students(should)have plenty of exercise is very good.The suggestion(that/which)he raised at the meeting is very good.对比发现上句中的that只起连接作用，在从句中不充当任何成分，因此它引导的是同位语从句，其中that不能省略；下句中that不仅起引导作用，同时在从句中还充当了动词raised的宾语，因此它是定语从句，此时that可用which代替，又因其在定语从句中充当宾语，故又可省略。四.巩固练习。五.课后反思。
因为是高三的学生，所以本节课主要以复习旧知识和巩固练习为主，而且在整节课中以学生为主体，让学生去活动以得出最后的知识，效果较好。但是因为有的学生基础知识较差，在活动中参与性不强。
