高三英语从句练习有哪些

  部分高三学生在复习英语从句时候的时候,不知道怎么掌握英语从句的类型。以下是小编整理高三英语从句类型,希望可以分享给大家进行参考和借鉴。

  一、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.

  二、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,amazed,astonished,aware,certain,confident,delighted,glad, grateful,happy, proud,sad,sorry,sure,surprised等。

  I am glad that you have come.

  你来了,我真高兴。

  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。

  三、表语从句

  在主句中担当表语的主谓结构称之为表语从句。

  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。

  四、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,由于先行名词的意义不同,也可用whether,who,when,where,what,why,how等引导。

  常见的先行名词有:

  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。

  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 引导主语从句时,that 没有意义,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,occur

  It 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,probable

  It is certain that free medical care

  will be given to mostpeople 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 knowledge

  It 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, announced

  It 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。

  从句: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。

  (三)改用“现在分词短语”和“过去分词短语”

  “现在分词短语”作后置定语

  此项要明白三点:

  (1)“现在分词短语”与前面的名词一定是主谓关系;

  (2)它隐含的时态为与谓语动词同一阶段的时态。

  例如:谓语是一般现在时或将来时,现在分词所隐含的是现在时、现在正在继续时;如果谓语动词为一般过去时或将来时,现在分词所隐含的时态为过去时、过去正在进行时;

  (3)being+-ed表示“正在进行时的被动语态”。如果信息的中心在什么时候可以用现在分词呢?

  当被修饰的名词为“不定代词”、“泛指意义的名词”或“专有名词”,可用现在分句短语作后置定语由于主语是泛指,句子的意思往往表达的是一条“道理”或一件“事实”,所以它们的隐含时为“一般现在时”,此时就可以用分词短语作后置定语。为了看清分词所隐含的时态,配上定语。

  为了大家看得明白,配上定语从句,把分词所替代的时间展示出来

  Anyone touching that wire will get

  an electric stock.

  任何人碰到那根电线就会触电。

  =Anyone who touches that wire will get an electric stock.

  注:虽然被修饰的词是泛指意义的词,但是如果从句里的时态不是同步,则不可以用“现在分词”去作后置定语,只能用“定语从句”。

  Do you know anybody who has lost a dog?

  你知道有谁丢了一只猫?

  定语从句所修饰的先行词可以是名词或代词,也可以是一个句子。定语从句通常位于先行词之后,由关系代词或关系副词引导。

  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。

  如:

  The computers and cables which

  make up the Internet are owned

  by people and organizations.

  Those who live alone or who are

  sick may have trouble in getting

  close to other people.

  The girl whose parents died in an

  accident is living with her

  grandmother.

  1)当先行词是all,anything,everything,something,nothing等不定代词。

  That is all that I've heard from him.

  He's the first person that I'm going

  to interview this afternoon.

  2)关系代词的省略

  在从句中作宾语的关系代词常可省略。关系代词紧跟介词,作介词宾语时不可用that,只可用which或whom引导从句,并且不可省略。

  如:

  This is one of those things with which we have to put up.

  This is one of those things (which\that) we have to put up with.

  3)引导定语从句的关系副词有when,where,why等。

  关系副词在从句中作状语,意义上相当于一个“介词+which”的结构。

  如:

  No one knows the reason why(=for which) he was so angry that day

  * 非限制性定语从句

  非限制性定语从句既可修饰先行词,也可修饰整个主句,起补充说明作用,与主句之间有逗号隔开,若省去,原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。

  如:

  Every object has a gravitational pull,which is rather like magnetism.

  “介词+which\whom\whose”引导的定语从句

  “介词+which\whom\whose”可引导限制性定语从句,也可引导非限制性定语从句,该结构中介词的选择取决于从句谓语动词的固定搭配,或先行词的习惯搭配。

  如:

  This is the computer on which he spent all his savings.

  It is written by a person with whom we are all familiar.

  *as引导的定语从句

  as引导的定语从句主要用于“such...as”及“the same...as”的结构中,代替先行词是人或物的名词。as引导非限制性定语从句时,代替整个主句,从句可位于主句之前、之后或中间。

  如:

  These are not such problems as can be easily solved.

  (as代替先行词problems)

  As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)

  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 / in 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。

  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 wants to see you?

  他就是想见你的人吗?(who/that在从句中作主语)

  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
