专题07重点语法知识梳理一：情态动词、连词及专练100题Grammar1：情态动词Ⅰ.情态动词一、概论情态动词是一种特殊的助动词，具有下列特征：1.情态动词具有一定的词义，能表达某种看法；如：can能，may可以，must必须，need需要，等等；2.情态动词不能单独作谓语，只能和实义动词的原形一起构成复合谓语；如：Youcanstayherebefore5:00o’clock.你可以在这呆到五点钟。Wemusthaveatalkrightnow.我们现在就必须谈谈。3.情态动词无人称变化，即任何事物做主语对情态动词来讲都无变化。但是情态动词有时态变化。时态变化会在以后分单词讲解，此处仅以can为例，看看人称对情态动词是否无影响：如：Icandanceverywell.我舞跳得很好。Hecanplaybasketballprettywell.他篮球打得很好。Iknowyoucanplaythepianofairlywell.我知道你钢琴弹得很棒。Theyallcanswimquitewell.他们游泳游得相当好。常见的情态动词can/can’t,能够/不能①表示"能、会",指脑力或体力方面的"能力"。例如:

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。例如:

Han

Mei

can't

be

in

the

classroom.韩梅不可能在教室里。

Can

he

e

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。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否定句型为:主语+can

not(can't/cannot)+动词原形+其它。表示"某人不能(不会、不可能)做……"。其中can't是can

not的缩略式,英国多写成cannot。例如:

You

cannot

pass

the

ball

like

this.你不能像这样传球。

I

can't

ride

a

motorbike.我不会骑摩托车。must/mustn’t,必须/禁止①表示“必须”，此时可用于肯定句或疑问句。例如：YoumustfinishyourhomeworkbeforeIeback.②用情态动词must提问，肯定回答用must；否定回答用needn’t。例如：MustIreturnthebooktoday?Yes,youmust./No,youneedn’t③用于否定句时，mustn’t的意思是“一定不要、不能”，而不表示“不必”例如：Youmustn’twalkyourdogonthegrass.你不能在草坪上遛狗。should/shouldn’t,应该/不应该should表示义务或责任时意为“应该”：

例如：We

should

learn

from

each

other.

我们应该互相帮助。

We

should

help

the

aged.

我们应该帮助老人。should

表示建议或劝告时意为“应该”：

例如：You

should

give

up

smoking.

你应该戒烟。

【注】有时语气较强，含有命令的意味：

You

should

leave

at

once.

你应该马上离开

。should的否定形式：shouldn’t不应该Students

shouldn’t

spend

too

much

time

playing

puter

games.

学生们不应当花太多的时间玩计算机游戏。★情态动词不能单独使用，必须与其后的动词原形构成谓语。如：Youcan’twalkyourdoghere.(can’t+walk)Youmustfinishyourhomeworktoday.(must+finish)三、情态动词分类1.表示义务——mustmust表示“必须”，强调主观，用于现在、将来时态，否定式needn’t。【鉴别haveto】haveto表示“不得不”，强调客观，用于现在，将来和过去时态。否定式为don’t/didn’t/doesn’twon’thaveto。2.表示猜测——must/may/might75%把握的猜测：must，否定can’t，句中通常有证据。50%把握的猜测：may，否定maynot，句中通常有notsure。25%把握的猜测：might，否定mightnot，句中通常有notsure。must猜测的不同时态：mustbeagoodstudent.musthaveeatentoomuchlastnight.3.表示请求——might/may/could/canmightcould比较生硬。【注意】：couldcan/can’t；maycan/may/can’t/mustn’t。4.表示能力——can/beableto表示现在或将来的能力时，用can或beableto；表示过去的能力时，could表示过去的本领；was/wereableto表示过去特定环境一次性的能力。5.情态实义双胞胎——need/dare作为情态动词时，need和dare无三单变化；否定直接加not；后面加动词原形；eed和areodesddotoodingsh；6.hadbetter/wouldrather肯定句：hadbetter/wouldratherdosth.否定句：hadbetter/wouldrathernotdosth.疑问句：Hadsb.betterdosth.?/Wouldsb.ratherdosth.?7.祈使句回答——willIwillIwon’t例：Pleasecleanyourchimneynextyear.Ok,Iwill.Don’teattoomuchnextyeat.Ok,Iwon’t.8.表示指责——can’t/shouldn’t/oughtnotto/mustn’t温柔建议：can’t;shouldn’t;oughtnotto;强烈禁止：mustn’t，表示危险情形时，必须用mustn’t。【课堂小练】Ⅰ.Choosethebestanswer(选择)1.MayIstopmycarhere?No,you.A.can't
