高三英语一轮复习英语语法 主从复合句

高三英语一轮复习英语语法 主从复合句

主从复合句表语从句在句子中作连系动词的表语的从句,它位于主句中的系动词之后。

例如: That is why he did not come to school yesterday./ It is because you are so clever.宾语从句在句子中作及物动词或介词的宾语。

①基本形式: (主句+)连词+从句主语+从句谓语+...②关于宾语从句连词的选择:若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如: They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。

) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster.(我不知道是不是该为他在校长跟前说点什么。

) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine.(他问我在哪儿能搞到那样的药。

) (从句来源于特殊问句Where can he get such medicine? )③宾语从句的时态问题: 如果主句是现在时,从句则用现在某一时态,甚至可以用过去时;如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。

如:I think I will do better in English this term.(我想本学期我的英语会学得好点。

) / The teacher asked the boy if the earth is round.(老师问那个男孩地球是不是圆的。

【专项训练】高中英语语法专项—— 复合句(含配套练习)

【专项训练】高中英语语法专项—— 复合句(含配套练习)

语法专项——复合句【复合句综述】复合句含有两个或两个以上主谓结构,其中一个主谓结构作另一个的成分。

(而并列句的两个主谓结构间是并列关系,而不是从属关系)。

复合句包含一个主句从句和一个或几个从句的句子,从句包含名词性从句(主语从句、宾语从句、表语从句和同位语从句)、定语从句和状语从句等。

当简单句的一个成分从词或词组变为句子时,整个句子就成为复合句了。

一、如何判断复合句1.What he said is wrong.(what he said,是一个主谓结构,he为主语,said为谓语,what是宾语。

What he said is wrong. 是另外一个主谓结构。

What he said作主语,is wrong系表结构作谓语。

因此,本句是复合句。

What he said 是名词性从句作主语)。

2.The boy who is wearing a hat is my brother.(The boy is my brother.是一个主谓结构who is wearing a hat也是一个主谓结构,作了前一个主谓结构中主语the boy的定语。

因此本句是复合句。

3.I was doing my homework when he came in.(I was doing my homework是一个主谓结构,he came in也是一个主谓结构。

后面一个主谓结构作前一个的时间状语。

因此是复合句。

4.The boy over there is my brother. (只有一个主谓结构,是简单句)5. I was doing my homework at six. (只有一个主谓结构,是简单句)【小叮咛】一个句子如果出现两个主谓结构,那它就不是简单句了,要么是并列句,要么是复合句。

是并列句时要有and, so, but,等并列连词或用分号。

是复合句时也要有连接词。

总之,只用逗号而不用连接词简单的把两个主谓结构连接到一起的句子是错误的。

新高考英语语法基础复习讲义[64](完结)主从复合句、指示代词、最高级解读

新高考英语语法基础复习讲义[64](完结)主从复合句、指示代词、最高级解读

2021届巴蜀中学新高考英语语法基础复习讲义[64](完结)主从复合句、指示代词、最高级解读什么是主从复合句?主从复合句是分句之间呈现主从关系的一种复合句,因此至少要包含两个谓语(主句一个,从句一个)。

从句是主句的一个组成部分,从属于主句,所以我们常说两者之间是主从关系。

引导词是分辨主句和从句的重要依据之一。

通常,从句需要引导词(有时可以省略),而主句则不用。

从句法角度看,从句本身就是某种句子的组成成分。

因此,在命名从句时,常以其担当的句子成分命名。

比如:用作主语的从句,就叫作主语从句;用作宾语的从句,就叫作宾语从句;用作定语的从句,就叫作定语从句...... 以此类推,其它类型的从句也都遵循这个命名方法。

因此,判断从句类型的关键是要能够准确判断从句在句子中担当的是什么组成成分。

具体示例如下:(红色字体是谓语动词,下划线部分是从句,斜体字是引导词。

)2.表语从句:从句作表语参照:My question is a simple one.例句:My4.定语从句:从句作定语参照:They went to the cinema near our school.5.状语从句:从句作状语参照:Ten years ago, he started to work in this6.同位语从句:从句作同位语参照:The news, an absurd story made up什么是指示代词?指示代词是代词的一种,主要用于指代事物或人等,因此常可以看作名词的代替品,一般包括:this(这个,表示单数),that(那个,表示单数),these(这些,表示复数),those(那些,表示复数)。

同时,指示代词也可以像形容词或限定词那样使用,放在名词或名词词组之前,进行修饰限定。

在句中,指示代词常用作主语、宾语、表语、定语等。

具体示例如下:(例句中的红色字体是谓语动词)1. 指示代词作主语:名词功能This is Tony.这(位)是托尼。

高一英语主从复合句单选题50题

高一英语主从复合句单选题50题1.I am not sure ____ he will come to the party.A.thatB.whetherC.whatD.when答案:B。

本题考查名词性从句中的宾语从句。

“I am not sure”后接宾语从句,根据句意“我不确定他是否会来参加聚会”,“whether”表示“是否”,符合语境。

“that”在宾语从句中无实际意义,且在“be sure that”结构中,通常表示确定的事情,此处不确定,所以A 选项错误。

“what”在宾语从句中需充当主语、宾语等成分,此处不缺成分,所以C 选项错误。

“when”表示时间,与句意不符,所以D 选项错误。

2.We don't know ____ the new technology will change our lives.A.thatB.whetherC.whatD.how答案:D。

本题考查名词性从句中的宾语从句。

“We don't know”后接宾语从句,根据句意“我们不知道新技术将如何改变我们的生活”,“how”表示“如何”,符合语境。

“that”在宾语从句中无实际意义,且此处需要表示方式的连接词,所以A 选项错误。

“whether”表示“是否”,与句意不符,所以B 选项错误。

“what”在宾语从句中需充当主语、宾语等成分,此处不缺成分,所以C 选项错误。

3.The question is ____ we can finish the project on time.A.thatB.whetherC.whatD.when答案:B。

本题考查名词性从句中的表语从句。

“The question is”后接表语从句,根据句意“问题是我们是否能按时完成这个项目”,“whether”表示“是否”,符合语境。

“that”在表语从句中无实际意义,且此处需要表示疑问的连接词,所以 A 选项错误。

“what”在表语从句中需充当主语、宾语等成分,此处不缺成分,所以C 选项错误。

高考英语语法知识复习(复合句)(温故篇)一、名词性从句概念与分类名词性从句相当于名词,可分别在句中作主语、表语、宾语和同位语。

因此,名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。

从属连词that:在从句中不充当任何成分,也没有任何意思,只起连接作用,因此往往可以省略从属连词if, whether:在从句中不充当任何成分,有意义,不可以省略连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose:在从句中充当成分,有意义,不可以省略连接副词where, when, why, how:在从句中充当成分,有意义,不可以省略一、主语从句1.由从属连词引导的主语从句:①Whether the country should build a nuclear power station is something we must discuss.那个国家是否应该建立核电站……②That light travels in straight line is known to all .光以直线传播2.由连接代词引导的主语从句:①What we need is more time. 我们所需要的是……②Whichever book you choose doesn’t matter to me.无论你选哪本书……③Whoever comes will be welcome.无论谁来……3.由连接副词引导的主语从句:①When the plane is to take off hasn’t been announced.飞机什么时候起飞……②Where he has been is still a puzzle.他到过哪儿……③How much water is flowing can be measured easily.水的流量是多少……4.关于形式主语it①It + be +形容词+ that-从句It is necessary that…有必要……It is important that…重要的是……It is obvious that…很明显……It is likely that….很可能②It + be + -ed 分词+ that-从句It is believed that…人们相信……It is known to all that…众所周知……It has been decided that…已决定……③It + be +名词+ that-从句It is common knowledg e that………是常识It is a surprise that…令人惊奇的是……It is a fact that…事实是…… 可应用于此句型的名词还有fact / shame / honor / question/pity等。

高考英语主从复合句主语从句在主句中用作主语的主谓结构称之为主语从句。

例句:That he will come to the discussion is certain.他来参加讨论是确定的。

That the moon moves round the earth is well known to all of us.月球绕地球转动,这是我们大家都熟知的。

When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。

主语从句放在句首,句子常常显得比较笨重,因此通常可以把it放在句首,作形式主语,而将主语从句放在后面。

例如上面的句子可以分别改写为:It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.宾语从句在主句中作谓语动词、介词及非谓语动词的宾语的主谓结构称之为宾语从句。

在引导宾语从句时,从属连词that在口语中和非正式文本中常省略。

1.动词后的宾语从句We know that a parrot can’t really speak.我们知道鹦鹉不会真的说话。

He wants to tell us what he thinks.他想告诉我们他所想的事情。

Knowing that it was going to rain, they decided to work inside the house.知道要下雨了,于是他们决定在室内工作。

(现在分词knowing的宾语从句)I want to know whether/if you still work in the factory.我想知道你是否还在工厂工作。

(不定式to know的宾语从句)The club will give whoever wins a prize.获胜者俱乐部将颁奖。

Up to now we can’t say whether his theory can stand the test.到目前为止我们还不能说他的理论是否经得住考验。

2.形容词的宾语从句有些形容词可以用that引导宾语从句,表示说话人对某一事物的态度并带有感情色彩。

常见的这类形容词有:afraid, aware, certain, confident, proud, sure等这样的心理意愿形容词。

I am afraid that you are wrong on this point.恐怕你在这点上是错误的。

He is quite confident that he will pass the examination.他很有信心通过这个考试。

表语从句在主句中担当表语的主谓结构称之为表语从句。

关键是对系动词的认知!One idea is that fish is the best brain food.有一种看法认为鱼是最好的补脑食品。

The problem is where we can hold our meeting.问题是我们可以在哪儿举行会议。

My question is how information is stored in the long-term memory.我的问题是信息是怎样储存在长期记忆中的。

That is what he really wants.那就是他真想要的东西。

It seems that everything goes smoothly.似乎一切都进行得很顺利。

同位语从句同位语从句用于对前面出现的名词作进一步说明,一般用连词that引导(当然其他连词也不能忽略的,比如:whether, who, when, where, what, why, how等引导。

同位语的名词常见的有:fact, idea, belief, news, hope, conclusion, evidence, suggestion, order, problem, report, decision.有时由于谓语较短,将同位语从句位于谓语之后,这也是考点所在。

如:I had no idea how many books I could borrow at a time.The news came that their team had won the championship.名词性从句的用法及定义1.That连接主语从句时,that 没有中文意义,也无语法功能,但不能省略。

It worried her a bit that her hair was turning gray.她的头发正在变白,这使她很不安。

that引导主语从句,it作形式主语,that不能省略。

That she is a rich woman is known to us all.众所周知,她是个富有的女人。

这是that 引导主语从句,that 不能省略。

这句话可以改为用it 作形式主语的句型。

2.从句作主语时,多数情况下由 it 作形式主语,而把主语从句放在后面,尤其是谓语部分(包括宾语)较短的情况下。

例:①It wasn’t very clear what she meant.不清楚她是什么意思。

②It is important that he should come on time.他按时来是很重要的。

③It is true that that man on the left is a well-known writer here.左边那个人是本地的一位著名作家,这是真的。

这里,第一个that 引导主语从句,是单纯的连词,无词义,不作句子成分。

第二个that是指示代词,作句子成分,是man 的定语。

3.whether既可以引导主语从句也可以引导宾语从句,但if不能引导主语从句。

whether 后面可以加or not, 而if 不能与or not 连用。

作介词宾语时不用if。

如:①Whether I knew John doesn’t matter.= It doesn’t matter whether I knew John.我是否认识约翰没有关系。

②Whether or not she’ll come isn’t clear.= Whether she’ll come or not isn’t clear.= It isn’t clear whether …. 她是否来还不清楚。

It +动词+从句seem, appear, happen, look, matter, make, strike, occurIt appeared that he had a happy childhood.看来他有一段幸福的童年。

It made us very happy that she was saved.她能化险为夷令我们大家很高兴。

It is +形容词+从句 true, strange, necessary, important, certain, wonderful, possible, likely, probableIt is certain that free medical care will be given to most people in our city.我们城市的多数人将享受免费医疗,这是一定的。

It is obvious that he has been treated.很明显他已经被款待了。

It is +名词+从句fact, surprise, pity, honor, common knowledgeIt is common knowledge that the moon cannot give out light.月亮不会发光,这是常识。

It is a surprise that you gave such an answer to the question.你对这个问题作了这样的回答,令人吃惊。

It + be+分词+从句said, reported, believed, known, decided, thought, expected, announcedIt is said that Jack has been to Europe.据说Jack去过欧洲。

It was reported that a new park will be built.据报道将要建造一个新的公园。

需要注意的是,作为形式主语的it并无实际意义,只是为了满足语法上的需要,避免句子头重脚轻,它代替的是句子的逻辑主语,而真正主语由从句或不定式充当。

形式主语一直都是高频考点,同学们需要多多练习。

定语从句的简化规律(一)改用“不定式”或“不定式短语”如果定语从句的时态与主句的时态具有同时性(包括谓语有情态动词)或之后性,则可以用“关系代词或关系副词+不定式”来简化,或直接用“不定式”来修饰先行词。

We moved to the country so that the children would have a garden in which they could play in.我们搬到了乡下,好让孩子们有个花园在里面玩。

改为:We moved to the country so that the children would have a garden in which to play.(二)改用“介词短语”介词短语替代定语从句有两种方式:(1)省略“关系副词+主语+be动词”或“关系代词+be动词”(2) 根据从句的意思改编。

We have never forgotten the days (when we were) at college.我们从来没有忘记在大学对书的日子。

I don’t know the person (who is) in your office.在你办公司的那个人我不认识。

He is not a person who likes to haggle over every ounce.改为:He is a person above personal interests.他不是一个斤斤计较的人。

限制性定语从句限制性定语从句修饰先行词,对先行词起修饰作用,紧接先行词之后,无逗号,若省去,原句意思不完整。

引导定语从句的关系代词有who, whom, whose, which, that等。

who, whom, whose用于指人,whose有时也可指物,相当于of which;which用于指物;that既可指人也可指物,但只用于限制性定语从句中。
