备战2015年中考二轮讲练测
专题 15: 复合句
(宾语从句、定语从句)(讲案)
一讲考点——考点梳理
一.宾语从句的定义
置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式,v.-ing形式后面都能带宾语从句。有些形容词(afraid,sure,glad等)之后也可以带宾语从句。
二.宾语从句中引导词的用法
在复合句中作主句的宾语,引导词有: 连词:that (that 常可省略),whether, if 代词:who, whose, what ,which 副词:when ,where, how, why 等。

(一)that引导的宾语从句(在非正式场合that可以省略) 可跟that从句做宾语的动词有:
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句:The boy believes that he will travel through space to other planets.
注意事项:当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。
例句:I don’t think it is right for him to treat you like that.在以下情况中that不能省略
当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省。例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.
当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省。例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.

当that从句是双宾语中的直接宾语时,that不可省。例句:I can’t tell him that his mother died. 注意事项:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语。 例句:I find it necessary that we should do the homework on time.(二)由whether,if 引导的宾语从句
由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的。 例句:I wonder whether(if) they will come to our party. 只能用whether,不能用if引导的宾语从句
在带to的不定式前例句:We decided whether to walk there.
在介词的后面例句:I’m thinking of whether we should go to see the film.
在动词后面的宾语从句时例句:We discussed whether we had a sports meeting next week 直接与or not连用时例句:I can’t say whether or not thet can come on time. 只能用if不能用whether引导的宾语从句
if引导条件状语从句,意为“如果”例句:The students will go on a picnic if it is sunny. if引导否定概念的宾语从句时例句:He asked if I didn’t come to school yesterday.
引导状语从句even if(即使)和as if(好象)时例句:He talks as if he has known all about it. (三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序。用于这种结构的动词常常是:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。 例句:Can you tell me whom you are waiting for?
英语中的连接副词有:when,where,why,how,在句中担任状语的成分。 例句:None of us knows where these new parts can be bought. 三.宾语从句的语序
宾语从句的语序是陈述句语序即:连接代词/副词+主语+谓语+其他成分。例句如下: I don’t know what they are looking for. Could you tell me when the train will leave? Can you imagine what kind of man he is? 四.宾语从句的时态
[来源学科网ZXXK]
主句是一般现在时,从句根据实际情况使用任何时态。例句:The headmaster hopes everything goes well. 主句是过去时态,从句须用过去时态的某种形式。例句:She was sorry that she hadn’t finished her work on time.
当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。例句:The teacher told his class that light travels faster than sound. 五.宾语从句的特点
宾语从句可以作及物动词、介词及形容词的宾语。 宾语从句的语序一律用陈述句语序。
连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。
whether 和 if 都可引导宾语从句,但 whether后可紧跟or not;whether从句可作介词的宾语。 如果从句太长,可以用形式宾语it.
被修饰的词叫先行词。定语从句不同于单词作定语的情况,它需要放在被修饰的词(即先行词)之后。定语 从句由关系词(关系代词、关系副词)引导,关系代词、关系副词位于定语从句句首。 关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语 从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。 1)who, whom, that
这些词代替的先行词是人的名词或代词,在从句中所起作用如下: Is he the man who/that you want to see?
他就是你想见的人吗?(who/that在从句中作主语)[1] He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。(whom/that在从句中作宾语)
2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换), 例如:
They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙。 Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。 3)which, that
它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如:
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未 有的繁荣。(which / that在句中作主语)
The package which / that you are carrying is about to come unwrapped. 你拿的包快散了。(which / that 在句中作宾语)
关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。 1)when, where, why
关系副词when, where, why的含义相当于\介词+ which\结构,因此常常和\介词+ which\结构交替使用,例 如:
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。 Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗? 2)that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\介词+ which\引导的定语从 句,在口语中that常被省略,例如:
His father died the year (that / when / on which) he was born. 他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十 年前居住过的地方。

试题分析:句意:--请你告诉我刚才老师说什么了?--抱歉,我正在忙于我的工作。分析:考查宾语从句的用法,从句要体现陈述语序。因此第一项,第三项正确,通过时间状语just now体现为一般过去时,因此第三项正确。故选C
考点:考查宾语从句的用法。 【例题二】No one knows ____ . A .what will the future be like B. what the future will be like C. what will be the future like
