河南初中定语从句
一、定语从句的概念
在复合句中,修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。
二、定语从句的关系词
引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包括where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。
三、定语从句的分类
根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
四、关系代词的用法
1. that 既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如:
Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语)

The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。(作主语)
Who is the teacher (whom) Li Ming is talking to?正在与李明谈话的老师是谁?(作宾语)
注意:(1)当定语从句中含有介词,介词放在句末时,who, that, which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如:
This is the house in which we lived last year.这是我们去年居住的房子。

(2)含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上。例如:

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)
