河南初中定语从句

  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 coat (that) I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语)

  2.which用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如:

  The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语)

  The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。(作宾语)

  3.who, whom用于指人,who 用作主语,whom用作宾语。在口语中,有时可用who代替whom,也可省略。例如:

  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。

  Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

  (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:

  This is the person whom you are looking for. 这就是你要找的那个人。

  (3)that 作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面。例如:

  The city that she lives in is very far away.她居住的城市非常远。

  (4)关系词只能用that的情况:

  a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如:

  He was the first person that passed the exam. 他是第一个通过考试的人。

  d. 先行词里同时含有人或物时,只能用that, 而不用which.例如:

  I can remember well the persons and some pictures that I saw in the room.我能清楚记得我在那个房间所见到的人和一些照片。

  e.以who或which引导的特殊疑问句,为避免重复,只能用that.例如:

  Who is the girl that is crying? 正在哭泣的那个女孩是谁?

  f.主句是there be 结构,修饰主语的定语从句用that,而不用which.例如:

  There is a book on the desk that belongs to Tom. 桌子上那本书是汤姆的。

  (5)关系词只能用which,而不用that 的情况:

  a.先行词为that, those时,用which, 而不用that.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)
