專題11重點語法知識梳理三：情態(tài)動詞及專練60題（原卷版）Ⅰ.情態(tài)動詞一、概論情態(tài)動詞是一種特殊的助動詞，具有下列特征：1.情態(tài)動詞具有一定的詞義，能表達某種看法；如：can能，may可以，must必須，need需要，等等；2.情態(tài)動詞不能單獨作謂語，只能和實義動詞的原形一起構(gòu)成復(fù)合謂語；如：Youcanstayherebefore5:00o’clock.你可以在這呆到五點鐘。Wemusthaveatalkrightnow.我們現(xiàn)在就必須談?wù)劇?.情態(tài)動詞無人稱變化，即任何事物做主語對情態(tài)動詞來講都無變化。但是情態(tài)動詞有時態(tài)變化。時態(tài)變化會在以后分單詞講解，此處僅以can為例，看看人稱對情態(tài)動詞是否無影響：如：Icandanceverywell.我舞跳得很好。Hecanplaybasketballprettywell.他籃球打得很好。Iknowyoucanplaythepianofairlywell.我知道你鋼琴彈得很棒。Theyallcanswimquitewell.他們游泳游得相當(dāng)好。常見的情態(tài)動詞can/can’t,能夠/不能①表示"能、會",指腦力或體力方面的"能力"。例如:

Jim

can

swim

but

I

can't.吉姆會游泳,但我不會。

②表示"可能",常用于否定句或疑問句中,指某種可能性。例如:

Han

Mei

can't

be

the

classroom.韓梅不可能在教室里。

Can

he

come

here

today,

please?請問他今天能到這里來嗎？

③表示"可以",常用于口語中,指許可或請求做某事。例如:

Can

I

have

a

cup

of

tea,

please?請問我可以喝一杯茶嗎？

You

can

go

out.你可以出去了？④否定句型為:主語+can

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

not的縮略式,英國多寫成cannot。例如:

You

cannot

pass

the

ball

like

this.你不能像這樣傳球。

I

can't

ride

a

motorbike.我不會騎摩托車。must/mustn’t,必須/禁止①表示“必須”，此時可用于肯定句或疑問句。例如：YoumustfinishyourhomeworkbeforeIcomeback.②用情態(tài)動詞must提問，肯定回答用must；否定回答用needn’t。例如：--MustIreturnthebooktoday?--Yes,youmust./--No,youneedn’t③用于否定句時，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,應(yīng)該/不應(yīng)該should表示義務(wù)或責(zé)任時意為“應(yīng)該”：

例如：We

should

learn

from

other.

the

aged.

up

smoking.

【注】有時語氣較強，含有命令的意味：

。should的否定形式：shouldn’t不應(yīng)該Students
