初中英语语法梳理和提高

 

    

动词是表示动作(study, find, swim 等)或状态(be, like, feel 等)的词。动词具有人称、数量、时态、语态和语态变化。

知识梳理:提纲挈领,抓住重点和难点!

动词分类:动词有助动词、情态动词、联系动词和行为动词四类。

一)助动词 助动词没有任何含义,不能单独做谓语,只能和行为动词一起构成谓语,帮助行为动词组成各种时态、语态、语气以及疑问或否定形式。常见的助动词有be, do, does, did, have, will, shall等。具体用法如下:

1、助动词be的用法如下1)构成各种进行时态。如:It was raining all day yesterday.昨天整天下雨。2)构成被动语态。如:The meeting was held yesterday afternoon.

会议是昨天下午举行的。3)与不定式连用表示按照计划、预先安排或规定要发生的动作。如:They are to see an English film this evening.他们今天晚上看英语电影。

2、助动词do的用法如下:1)构成疑问式或否定式。如:Does he think so?I didn’t say anything about the result. 2)在动词前加上do, does, did表示强调,意为的确,确实。如:

They do study hard.  She does love him.  He did want to help the old man.

3have:  助动词have 的过去式是hadhavehad均可与动词过去分词一起构成完成时态。如:He has lived here for three years.As soon as the sun had set they returned.

4shall, should: 助动词shall只用于第一人称的将来时态;助动词should shall的过去式,构成过去将来时。如:I shall send ten letters to my good friend.

She wanted to know if I should go to the palace.

二)情态动词

情态动词本身有一定含义,但不能单独作谓语,要和行为动词一起构成谓语。它们也能表明句子的否定、疑问或时态上的区别。常见的情态动词有:can, may, must, need, should等。

表示能力

表示能力一般用can, could。如:Rose can speak now, but she couldn’t a week ago.

be able to 也表示能力,它和can 的区别如下:

1)表示做事的能力,两者可通用。但can 只能用于一般现在时和一般过去时。be able to 可用于任何时态。如:She could / was able to eat four pieces of bread when she was young.

They will be able to finish the drawing soon.

2) 表示过去经过努力而成功的某一次动作,只能用was/were able to, 但在否定句中可互换。如:She was weak, but was able to finish the task last night.

can (could) 在疑问句中与第二人称连用时,表示征求对方意见或提出请求,表示委婉语气。虽然couldcan的过去式,但是could 只是表示比can语气更加委婉客气,没有时间上的差别。如:-Could you lend me your pen?-Yes, I can.

表示许可  表示许可一般用may/might, can/could, 而且常可互换。Might, could语气比较

婉。要特别注意:回答以might, could开头的疑问句只能用may, can 给予直截了当的答。

-Might/Could I borrow your book? -Yes, you may/can.

表示必需、必要musthave to都有必须,一般情况下可互换。如:You must / have to finish

the work..但他们有如下区别:

1must 表示说话人的主观看法;have to 表示客观需要。如:

I must have a talk with him.

He has to give up smoking because of badly cough.

2) 否定式mustn’t 表示禁止,意为不准,不可以做don’t have to 意为不必。如:

You mustn’t hit her.

You don’t have to explain it to me if you dislike the job.

注:表示推测的情态动词有表示一定must, 表示很有可能should, ought to 和表示可能can, could, may, might具体用法如下:

must 表示较有把握的推测,只用于肯定句,不能用语否定句或疑问句。用法如下:

1)对目前动作的推测,用must+动词原形。如:

You must lose in the mountain.

2) 对目前状态的推测,用must + be + 表语。如:You speak for 4 hours, you must be thirsty.

在肯定句中,表示对现在或将来把握不大的推测用may (might) +动词原形,might may

的可能性更小;对过去把握不大的推测用may (might) have+ 过去分词。如:

The package might come tomorrow. They may have killed the enemies.

3、在疑问句中,对现在表示推测用can (could) …+动词原形,对过去表示怀疑则用can (could) …have+过去分词;在否定句中,对现在表示推测用can’t+动词原形,对过去表示推测用can’t (couldn’t) have+过去分词。如:It can’t be John. He has gone to UK.

4need的双重身份 need 既可作情态动词又可作实意动词,它们的用法不同,如不注意区分,就容易用错。

三)系动词 连词动词的种类

联系动词含有一定意义,它们要与其后做表语的形容词、名词或介词(短语)一起构成合成谓语。系动词按意义可分为三类,而且有自己的特定用法。

1、按意义联系动词有:be, appear, seem, keep, remain, continue, stay, prove 等,如:Jim appears very old.

2、表示感觉的联系动词有look, feel, smell, sound, taste等。如:It smells bad.

3、表示转变的联系动词有become, fall, get, go, grow, turn等。如:

   She becomes more beautiful than three years ago.

四)行为动词

    行为动词又称实义动词,它们都含有实在的意义,表示动作或状态,可在句中独立作谓语。行为动词又分为及物动词和不及物动词。

1、及物动词

及物动词后一定要跟宾语,意思才能完整。如:

My mother told me she wanted to buy some books for me.

2、不及物动词  不及物动词意义完整,不需带宾语,但如果有些不及物动词非要带宾语时,必须先加介词后加宾语。如:He only worried about his daughter.

二、动词的时态  动词的时态有很多。初中阶段主要掌握八种:一般现在时、一般过去时、现在进行时、过去进行时、一般将来时、过去将来时、现在完成时、过去完成时。
