  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,有完整的迟坦词义,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仔搭去时,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。

  (1)when,if引导宾语从句:主句一般现在时,从句可使用任何时态;主句使用过去时,从句也要使用过去的某种时态;

  (2)When,if引导时间状语从句:遵循主将从现原则(主句将来时,从句一般现在时,即从句不可出现when/if + 主语 + will/be going to do的形式)

  2.到达的三种表达方法:

  arrive at/in someplace = get to someplace = reach someplace

  3.let`s , let us用法

  (1)Let`s do sth: 让我们做某事吧(说者和听者共同来做),

  表示征询建议,反义疑问句will you?

  4.go fishing:钓鱼;

  5.nobody:是不定代词,不定代词做主语时,谓语动词使用单数形式。常见不定代词:

  anybody,anyone,anything,someone,somebody,something,everyone,everybody,

  英语语法(复合句)讲解:状语从句

  一、状语从句的定义及分类

  状语从句在复合句中修饰主句或者主句中的动词。状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,前面一般不用逗号。状语从句根据其用途可以分为:时间状语从句、原因状语从句、结果状语从句、条件状语从句、让步状语从句、地点状语从句、目的状语从句等。

  二、时间状语从句

  1.when的用法

  ① when意为“当……时候”,引导时间状语从句,表示主句的动作和从句的动作同时或者先后发生。

  I feel very happy when you come to see me.

  When you are crossing the street, you must be careful.

  ② when引导的时间状语从句中的动词可以用延续性动词或者非延续性动词。

  I worked for a foreign company when I was in Shanghai.

  2.while的用法

  while引导的时间状语从句,常常翻译为“与……同时、在……期间”,while引导的从句常用延续性动词或表示状态的动词。

  They rushed in while we were discussing problems.

  My mother was cooking while I was doing my homework.

  3.as的用法

  as引导时间状语从句时可以表示“正当、一边……一边……、随着”等意思。

  We get wiser as we get older.

  4.before/after的用法

  before表示“在……之前”,after表示“在……之后”。

  I will always work hard before I enter Peking University.

  She showed me many beautiful stamps after I got to her home.

  5.until/till的用法

  until和till都表示“直到”,常可互换,但till不用于句首。

  ① 主句谓语动词是延续性动词时,主句用肯定形式,表示这一动作或者状态一直持续到until/till引导的从句的动作发生为止。

  I'll wait for you until you come to see me.

  ② 主句的谓语动词是非延续性动词时,主句用否定形式,表示主句的动作直到until引导的从句的动作发生才发生,构成not...until结构,表示“直到……才……”。

  I didn't go to bed until I finished my homework.

  6.since的用法

  since引导的时间状语从句,表示“自……以来”,主句用现在完成时,从句用一般过去时。

  I have worked in this company since I graduated from Peking University.

  7.as soon as的用法

  as soon as引导的时间状语从句,表示从句的动作一发生,主句的动作随即发生,意为“一……就……”。该从句经常用一般现在时表示将来。

  As soon as he arrives, I'll tell him.

  三、条件状语从句

  主句为祈使句、一般将来时或含有情态动词时,条件状语从句用一般现在时。

  1.if的用法

  if引导条件状语从句,表示“如果、假如”。

  I'll visit the Great Wall if it doesn't rain tomorrow.

  2.unless的用法

  unless引导条件状语,表示“除非、如果不”,相当于if not。

  We'll go for an outing tomorrow unless it rains.

  四、原因状语从句

  原因状语从句通常用because, since或as引导,这三个词所表示的语气由because到as逐渐减弱。

  1.because的用法

  because表示因果关系时,语气最强,用来回答why的提问,所表示的原因往往是听话人所不知道或者感兴趣的。

  I'm leaving because I am fed up with the boss.

  My friends admire me because I am handsome and successful.

  2.since的用法

  表示人们已知的事实,不需要强调的原因,因此常常翻译为“既然……”,通常放在句首。

  Since Monday is Bob's birthday, let's give him a party.

  Since everyone is here, let's get started.

  3.as的用法

  as与since差不多,所引出的理由在说话人看来已经很明显,或已为说话人所熟悉。

  She didn’t hear us come in as she was asleep.

  五、目的状语从句

  目的状语从句通常由so that,in order that等引导,谓语中常含有may, might, can, could, will, would等情态动词。

  He must get up early so that he can go to work on time.

  六、结果状语从句

  1.由so...that, such...that引导

  so...that与such...that引导结果状语从句时,在结构上有所不同:

  so+形容词/副词+that

  such+a/an+形容词+单数名词+that

  such+形容词+复数名词+that

  such+形容词+不可数名词+that

  so+形容词+a/an+单数名词+that

  注意:当名词前面有many, much, little, few修饰时,用so而不用such。

  She is such a lovely girl that we love her very much.

  =She is so lovely a girl that we lover her very much.

  We have so much time that we can finish the work very well.

  2.结果状语从句与不定式结构的相互转换

  so...that句型的否定形式可与too...to...或者not...enough to相互转换。

  He is so young that he can't go to school.

  =He is too young to go to school.

  =He is not old enough to go to school.

  七、让步状语从句

  1.though/although的用法

  although和though意义一样,意为“虽然、尽管”,都表示让步,一般情况下可以互换,两者可以与yet连用,但是不与but连用。

  They are generous though they are poor.

  Although he was a Japanese, he spent most of his life in China.

  2.even though/even if的用法

  even though和even if都是“尽管、即使”的意思,表示语气更强的让步。

  Even though he's 24 now, he's still like a little child.

  We'll make a trip even if/even though the weather is bad.

  八、地点状语从句

  引导地点状语从句的从属连词主要是where和wherever。
