动词是表示动作或行为的词。按其词义和在句子中的作用可以分为连系动词、助动词、情态动词和行为动词。

1、be动词(am,is,are)

① be动词做谓语时,要与主语在人称和数上保持一致。

用法口诀: 我用am,你用are,is 用在他、她、它,复数全用are。

如:I am a teacher. You are a student. She is a nurse. We are Chinese. ② be动词的否定形式:am not(无缩写形式),is not=isn?t,are not=aren?t 2、助动词(do,does,did)

① do,does用于一般现在时,does用于第三人称单数,其他人称和数用do。其过去式did用于一

- 8 -

般过去时。他们通常用在疑问句和否定句中。助动词后动词要用原形。 如:Do you like this film?

Does she like playing football? I didn?t go to school yesterday.

② 否定形式:do not = don?t,does not =doesn?t,did not=didn?t

3、情态动词(can,may,must,should,will,would,shall等)

情态动词表示说话人对某一动作或状态的态度,表示“可能”,“可以”,“需要”,“必须”,“应当”等意思。情态动词没有人称和数的变化,后面的动词要用原形。

1)can和may都可以用来表示请求或允许,但may比can更正式,更客气些。 如: Can I use your pen? May I come in? 2)must和should

① must意为“必须,应当”,含有一种命令的语气,比较生硬,不容商量。 ② should意为“应当,应该”,表示建议或劝告,语气比较委婉,客气。 如:You must finish your homework before you go to bed. You should stay in bed and have a good rest.

3)will和would用于疑问句,表示说话人向对方提出请求或询问,用would比will更委婉,更客气。如:Will you please open the window? Would you like some coffee? 注意区别:

I?d like… 我想要……(接名词) 如:I?d like some tea.

I?d like to… 我想要做……(接动词原形)如:I?d like to go with you.

I like… 我喜欢……(接名词或动名词)如:I like monkeys. I like reading. 4) shall 在问句中表示征求对方的意见,主要用于第一人称。

如:Shall we go there by bus?

5)否定形式:can?t,may not,mustn?t,shouldn?t,wouldn?t,shall not 4、行为动词

行为动词也叫实意动词,是具有实际意义的动词。如run(跑), jump(跳), listen(听),sing(唱),eat(吃),think(想)等。 行为动词在句子中有人称和时态的变化。

在英语中,不同时间里发生的动作或存在的状态,需要用不同的动词形式来表现,这就叫时态。

第16讲 句法

1、陈述句

说明事实或陈述说话人观点的句子。基本结构:主语+谓语+其他 1)肯定陈述句 We all like pandas very much.

2)否定陈述句 He doesn?t do housework at weekends 3)肯定陈述句改否定陈述句

①一般是在be动词或情态动词后加not。

Mary was at school yesterday. —> Mary was not at school yesterday. I can make a model plane. —>I can not make a model plane.

②不含be动词或情态动词的,行为动词前要用助动词的否定式(don’t,doesn’t,didn’t),后面跟动词的原形。

He likes drawing pictures.—>He doesn?t like drawing pictures. I went to the park yesterday. —>I didn?t go to the park yesterday.

4)陈述句改一般疑问句

①有be动词或情态动词的,把be动词或情态动词提前。

Mary was at school yesterday. —> Was Mary at school yesterday? I can make a model plane. —> Can you make a model plane?

②不含be动词或情态动词的句子,借助助动词开头,动词还原成原形。

He likes drawing pictures.—>Does he like drawing pictures.

I went to the park yesterday. —>Did you go to the park yesterday? 2、疑问句

用来提出问题,询问情况的句子,末尾用问号。

1)一般疑问句:一般疑问句常用来询问一件事是否属实,通常以be动词,助动词或情态动词开头,用yes或no来回答,因此又叫是非疑问句,通常读升调。

—Is Mr Green from the UK? —Yes,he is. / No,he isn?t. —Do you have any hobbies? —Yes,I do. / No,I don?t. —Can you play the guitar? —Yes,I can. / No,I can?t.

2)特殊疑问句:以特殊疑问词引导,要求回答具体问题,不能用yes或no来回答。—How do you go to work every day? —I go to work by car.

3)选择疑问句:提供两种或两种以上情况,让对方选择,往往用or连接。 —Would you like some tea or coffee? —Some coffee, please.

4)反意疑问句:反意疑问句是由陈述句和附在其后的附加疑问句组成。 —It?s a fine day, isn?t it? — Yes ,it is. 3、祈使句

表示请求或命令别人做某事或不做某事。 1)用于第二人称,通常省略you。

①肯定祈使句:Open the door, please. ②否定祈使句:Don?t be late again.

2)用于第一人称和第三人称,通常以let(let后跟宾格)或shall开头。 Let me have a look. Let?s play a game now. Let him go home now. Shall we meet at one thirty in front of the Garden Theatre? 4、感叹句

表达喜怒哀乐等强烈感情,句尾常用感叹号(!),语气用降调。 1)what + 名词或名词性短语 What a big garden (it is)!

What an interesting storybook (it is) ! What lovely weather (it is)! What pretty girls (they are)!

2)how +形容词或副词+主语+动词 How nice!

How beautiful the flowers are! How tall Yao Ming is!

5、there be 句型 表示在某地有某人或某物。

1)主语是单数,be动词用is(was);主语是复数,be动词用are(were)。 There is some milk in the fridge.

There are some peaches in the basket.

2)如果有几个不同的人或物并列存在,be动词根据最靠近的那个名词而定。 There is a ruler and five knives in the pencil case. There are five knives and a ruler in the pencil case. 3)there be句型和have/has区别:

there be句型表示某地有某人或某物;

have/has表示某人有某物。has用于第三人称单数,其余人称和数用have。 There are some English books on the desk. I have some English books.
