二、情态动词

1、概念

情态动词表示人的主观愿望，本身有一定的词义，但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词主要有下列：can (could), may (might), must, need, ought to, shall (should), will (would)

另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。

2、情态动词can具体用法

（1）表示"能、会",指脑力或体力方面的"能力"。

例如:

I can speak English.我会讲英语。

Jim can swim but I can't.吉姆会游泳,但我不会。

（2）表示"可能",常用于否定句或疑问句中,指某种可能性或揣测，此时can't 译为" 不可能"。

例如:

Han Mei can't be in the classroom.韩梅不可能在教室里。

Can he come here today, please?请问他今天能到这里来吗?

3.表示"可以",常用于口语中,指许可或请求做某事，可以代替may。

例如:

Can I have a cup of tea, please?请问我可以喝一杯茶吗?

You can go out.你可以出去了。

4、补充：can的过去式could，意为"能、会"，表示过去的能力

如：He could write poems when he was 10.他十岁时就会写诗。

could在疑问句中，表示委婉的语气，此时could没有过去式的意思。如:Could you do me a favor?你能帮我个忙吗？

—Could I use your pen?我能用一下你的钢笔吗?

—Yes, you can.可以。（注意回答）

5、情态动词can的基本句型：

（1）.肯定句型为:主语 can 动词原形 其它。

（2）否定句型为:主语 can not(can't/cannot) 动词原形 其它。

I can't ride a motorbike.我不会骑摩托车。

（3）疑问句句型分为:一般疑问句句型和特殊疑问句句型两种类型。

⑴一般疑问句句型为:Can 主语 动词原形 其它。表示"某人会(能。可以)做……吗?",用于口语时,常表示请求或许可。

其肯定答语用""Yes,主语 can."作答;否定答语用"No,主语 can't."作答。

注意答语中做主语的人称代词,应根据问句中的主语作相应的变化。其变化规则为:第一人称问,则第二人称答;第二人称问,则第一人称答;第三人称问,第三人称答。

例如:

①-Can you sing an English song for us?

你可以为我们大家唱一首英语歌吗?

-Yes.行。(注意在Yes后面常省略I can)

②-Can I skate?我可以滑冰吗?-Yes, you can.可以。

③-Can she climb hills?她能爬山吗?-No, she can't.不,她不能。

该句型中的特殊疑问词常用how many, how much等。

What a fine day it is! ②What (形容词） 可数名词复数或不可数名词 主语 谓语！What kind women they are! What nice music it is!

其结构是：How 形容词（副词） 主语 谓语！

How hard the worker are working!

How clever the girl is! How quickly the boy is writing!

注意：当how修饰动词时，动词不跟着感叹词提到主语之前。

How the runner runs!

3、感叹what和感叹句how的区别

（1）"what"意为"多么"，用作定语，修饰后面的名词（被强调部分，该名词前常有形容词修饰语）单数可数名词前要加不定冠词a/an；复数可数名词或不可数名词前不用冠词。（2）"how"意为"多么"，用作状语，修饰形容词或副词（被强调部分）。如果how修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词。

（3）注意

在感叹句的主语前若还有名词存在时，用What来引导；在感叹句的主语前若无名词时，则用How来引导。 What a clever girl she is! 多么聪明的姑娘呀！

What good children they are! 他们是多么好的孩子呀！ How cold it is today! 今天多么冷呀！ How happy they look! 他们显得多么高兴呀！ 但在"How 形容词 a / an 名词单数 主谓！"中不可用What，因为此句中强调了形容词。 How naughty a boy your brother is!

4、练习，用what或how填空

① ________ a big tree it is! ②________ big the tree is!③________ beautiful pictures!④ ________ beautiful the pictures are!⑤ ________ high the building is!⑥_______ big eyes she has!⑦________ lovely the ice-cream is!⑧ ________ lovely ice-cream!

答案：what、how、what、how、how、what、how、what

九、选择疑问句

1、概念

选择疑问句表示提供两种或两种以上的情况，要求对方在所提供的范围、对象内选择。在所提供的最后一个备选对象前面用表示选择关系的并列连词or（或者），朗读时or前用声调，or 后面用降调，句末用问号。

2、选择疑问句的结构

（1）、"一般疑问句 or 另一个备选对象"。例如：

Shall we go there by bus, bike or train?

我们乘公共汽车、自行车还是火车去？（备选对象为三者）

Would you like some tea or coffee?

你要茶水还是咖啡？ （备选对象为二者）

Did you stay at home or at school yesterday?

你昨天呆在家还是在学校？（备选对象为二者）

（2）"特殊疑问句 or 另一个备选对象"。例如：

Which would you like best, English, Chinese or Math?

你最喜欢哪门学科，英语、语文还是数学？

When will you go to Canada, Sunday or Monday?

你何时去加拿大，星期天还是星期一？

3、选择疑问句的回答

回答选择疑问句时，一般在所提供的备选对象范围内选择，有时也要视具体情况作灵活处理，但是不能用Yes / No来回答，一般用一个完整的陈述句或其简略形式，主语和谓语均省略。

近年来的考试趋势逐渐使用一个关键词，即不定代词作简略回答。

（1）、从备选对象中选择其中某一项回答。

─ Are you going to borrow a dictionary or a magazine?

─ ____. （2005年江苏南通）

A. Yes, a dictionary B. No, a magazine C. A magazine D. Yes, both

分析：选项A, B, D不能回答选择疑问句。选项C是从备选对象中选择了其中的一项来回答的，符合语境。

（2）、选对象是二者，可任选其一就用表示肯定的either；两个对象都选就用表示肯定的both；两个对象都不选就用表示否定的neither。

─Would you like chicken noodles or beef noodles?

─____. I'd like tomato noodles. （2008年宁波）

A. Either B. Neither C. Both D. None

分析：备选对象是二者，先排除D。由回答可知，要否定上面提供的备选对象。而A和C不符合逻辑，故选B。

（3）如果备选对象是三者，可任选其一时，就用one of them（他〈它、她〉们中任意之一）；三个对象都选就用all；三个对象都不选就用none。

─Which do you like best, coffee, water or juice?

─_____. I only like tea.

A. Both B. Either C. Neither D. None

分析：备选对象是三者，排除A, B, C。选择D选项，意为"咖啡、水和果汁都不喜欢。我只喜欢茶水。"
