初中英语 定语从句篇一

定语是用来限定、修饰名词或代词的。下面就是老师为同学们带来的对定语从句的详细讲解,供同学们学习的参考。

知识点总结

要学定语从句,得知道什么是定语。定语是用来限定、修饰名词或代词的。例如,a good book, good就是定语。那么复合句中修饰名词或代词的从句就叫做定语从句。定语从句由关系代词或关系副词引导,相当于形容词,在句中作定语。被定语从句修饰的词叫先行词,定语从句一般放在先行词的后面。引导定语从句的关联词称为关系词,关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose等,绝对没有what;关系副词有where, when, why,how等。关系词放在先行词和定语从句之间,起连接作用,同时又作定语从句的某个成分。

一、关系代词引导的定语从句

1、由who, whom, that,Whose引导的从句

这些词代替的先行词是人的名词或代词,who作主语指人,whom作宾语指人,that既可作主语又可作宾语(作宾语可以省略),可以指人也可以指物。Whose 用来指人或物,只用作定语。

(1) Is he the man who/that wants to see you? 他是那个想见你的男人吗?(who/that在从句中作主语)

(2) 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)

(3) The man whom you spoke to just now is our English teacher 你刚刚说话的那个男人是我们的英语老师

(4) he man whose son is a doctor is our professor. 那个儿子是医生的男人是我们的教授。

2、由which, that引导的从句

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,作宾语时可以省略,例如:

(1) 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在从句中作主语)

(2) The package (which / that) you are carrying is about to come unwrapped. 你拿那个包裹快要散开了。(which / that在从句中作宾语)

注意: 代表物时多用which,但在下列情况中用that而不用which:

a)先行词是anything, everything, nothing , none等不定代词时;

b)先行词由every, any, all, some, no, little, few, much等修饰时,这时的that常被省略;

c)先行词前有序数词或被形容词最高级修饰时;

d)先行词中既有人又有物时;

e)整个句中前面已有which,who,that时;

f)当先行词为物并作表语时;

g)先行词为one时;

h)先行词同时又被the only,the very,the same修饰时;

二、关系副词引导的定语从句

1、when指时间在定语从句中做时间状语也可做连接词用 I still remember the day when I first came to the school.

2、where指地点在定语从句中做地点状语 Shanghai is the city where I was born.

3、why指原因在定语从句中做原因状语 ,用在reason 后面。 Please tell me the reason why you missed the plane.

常见考法

对于定语从句的考查,多以单选的形式考查学生灵活运用的能力。一般情况下,常从关系词的意义和功能的角度考查,重点是that,which,who引导的定语从句。

典型例题:You're the only person ______I've ever met ______could do it.

A. who B. whom C. whom D. who

解析:先行词person后有两个定语从句,第一个从句省略了关系代词whom.因为, whom作从句中met的宾语,可以省略.第二个从句who could do it.who在从句中作主语,不可省略.

答案:D

误区提醒

当表示时间或地点的名词作先行词时,要判断出它们在从句中作状语还是主语或宾语。作状语时用关系副词,反之用关系代词。

典型例题:I can never forget the day _______ we worked together and the day ______ we spent together.

A. when; which B. which; when C. what; that D. on which; when

解析:. 两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句.

答案:A

上述是对定语从句的详细讲解,有不懂得可以参考等更多相关知识的学习!

初中英语语法大全:动词的种类

关于英语中动词的种类知识,希望同学们很好的掌握下面的内容学习。

动词的种类

动词是表示动作或状态的词,按其词义和在句子中的作用可分为行为动词,连系动词,助动词和情态动词。

1.行为动词

行为动词可分为及物动词 (vt)和不及物动词(vi),及物动词表示动作或状态,有完整的词义,能单独作谓语,后跟宾语;不及物动词表示动作或状态,有完整的词义,能单独作谓语,但后面不能直接跟宾语,如要带宾语则与介词或副词构成短语。

如:

More and more people study English.(vt)

The students are listening to the teacher carefully.(vi)

2.连系动词

连系动词本身有一定的词义,但不能独立作谓语,必须与表语一起构成谓语。常用的连系动词有 be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。

如:

Our country is becoming stronger and stronger.

It feels damp.

3.助动词

助动词本身无词义,不能单独作谓语,只能和主要动词一起构成谓语动词,表示否定,疑问及动词的时态、语态、人称和数等语法特征,助动词有 be,do,have,shall,will等。

如:

How do you usually come to school?

The children are playing yo-yo now.

4.情态动词

情态动词本身有一定的意义,但不能独立作谓语,只能和主要动词原形一起构成谓语,表示说话人的语气和情态。情态动词没有人称和数的变化。情态动词有 can (could),may(might),must, need, ought to, dare等。

如:

Can I help you?

- Must we go now? -No, you needn't .

a. can与be able to的用法有所区别。can只用于一般现在时和过去时,指本身有能力的"能";be able to用于各种时态均可,指须经过努力而"能"。

b. must与have/has to的用法。must表示说话人主观认为"必须",只用于一般现在时和一般将来时;have/has to表示客观需要,意为"不得不",它可用于各种时态。

c.need和dare既可作情态动词也可作行为动词。

以上对动词的种类知识的内容讲解学习,相信同学们已经能很好的掌握了吧,希望同学们在考试中取得很好的成绩。

初中英语语法大全:动词不定式的形式

对于英语的学习中,关于动词不定式的形式知识点的内容,我们做下面的讲解学习哦。

动词不定式的形式

1.作主语。 如:

To learn English is very important.

但实际上不定式作主语常用 it来作形式主语,而将不定式移至谓语动词后作真正的主语。

如上句可表达为:

It's very important to learn English.

2.作表语。 如:

My idea is to ring him up at once.

3.作宾语。 如:

I have decided to go to Binjiang Primary School.

4.作宾语补足语。

a. ask, want, teach, tell, know, would like, allow等动词后面接动词不定式作宾语补足语。

如: The policemen asked him to get off the bus.

b. hear, see, look at, feel, watch, notice, listen to等动词后接不带to的动词不定式作宾语补足语。

如: We often see Miss Li clean the classroom.

c. let, make, have这些使役动词后接不带to的动词不定式作宾语补足语。但在被动语态中这些不带to的都须带上to。

如: In those days the bosses often made the workers work day and night.

d.动词help接动词不定式作宾语补足语,可带to也可不带to。

如: Can you help me (to) carry the heavy bag?

5.作定语。

a.与被修饰词有动宾关系。如:I have something important to tell you.但如果不定式动词为不及物动词,后面的介词千万不要省略。

如: Maybe they have three rooms to live in.

b.与被修饰词有主谓关系。

如: Mr Liang is always the first to come and the last to leave.

c.与被修饰之间只有修饰关系。

如: I have no time to play cards.

6.作状语,表示目的、原因、方法、方向、结果等。

如: I'll go to meet my friend at the railway station.

7.不定式复合结构"for sb. to do sth" 作主语时,常用"It is +adj+ for

of sb. to do sth"的句式。形容词good, bad, polite, unkind, kind, ice, clever,

right, wrong, careful等用"It is +adj +of sb. to do sth."

其他形容词用 for。

如:

It's dangerous for you to ride so fast.

It's very kind of you to help me.

8.动词不定式与疑问句who, what, which, when, how, where, whether等连用。

如: I don't know when to start.

He didn't tell me where to go.

但上面结构相当于一个从句,故上述句子也可表达为:

I don't know when we'll start.

He didn't tell me where he would go.

注意:

a.有些动词或动词短语不能带不定式,只能接动词的-ing形式。

如: enjoy, finish, keep, mind, miss(错过),be busy, go on, keep on, be worth, practise等。

如: The peasants are busy picking apples.

Would you mind my opening the door?

b.有些动词后可接不定式,也可接动词的.-ing形式,但意思不同。

如: Lu Jian forgot to post the letter.(该寄但还没做)

Lu Jian forgot posting the letter.(已经寄过信了)

They stopped to sing a song.(停止在做的工作而去做另一件工作)

They stopped singing.(停止正在做的工作)

希望上面对动词不定式的形式知识的内容讲解学习,同学们都能很好的掌握,相信同学们会取得很好的成绩的哦。

初中英语 定语从句篇二

一 . 误用关系词

1. I'll never forget the days when we spent together on the farm.

2. This is the factory where he was invited to visit last month.

分析:定语从句的先行词是表示时间或地点的名词或代词时,引导定语从句的关系词不一定都是 when 或 where 。关系词的选择主要取决于定语从句中的谓语动词。如果从句的谓语动词是及物动词而且其后没有宾语,就用关系代词 that 或 which 作宾语。如果从句的谓语动词是不及物动词或者是后面已经有了宾语的及物动词,就用关系副词。在句 1 和句 2 中,从句谓语动词 spent 和 visit 都是及物动词,而且后面又没有宾语,所以应分别将 when 和 where 改为 that 或 which 。

二 . 宾语重复

1. As we all know it, the earth is round.

2. The manager discussed the plan that they would like to see it carried out the next month.

分析:如果关系代词在从句中作宾语,则谓语动词后面就不能再有宾语。在句 1 中,关系代词 as 作从句谓语动词 know 的宾语,因此, it 就是多余的,应去掉。在句 2 中,关系代词 that 在从句中作动词 see 的宾语,因此 it 也是多余的,应去掉。

三 . 缺少先行词或关系词

1. Is this park where his father works?
