第8講：Module4語法篇

語法：情態(tài)動(dòng)詞的用法

一、提建議。

在英語中，我們可以用其他多種方式提出我們的建議或征求對(duì)方意見。

(1).用“Let'sdo...”來提出建議。如：Let'sgoforawalkaftersupper.

(2).用“What/Howabout…?”來提出建議；about后接名詞或動(dòng)詞ing形式。如：Whatabout/Howabouta

drink?Whatabout/HowabouttakingTomwithus?

(3).用“Whynot...?”來提出建議，表示“何不......"not面后接動(dòng)詞原形。“Whynot...?”實(shí)際上是“Why

dorftyou/we…?”的簡(jiǎn)略形式。如：Whynotmeetattheschoolgateateight?Whydorftwestayhere

anotherday?

(4).用“Wouldyoulike...?”來提出建議，意思是“你想要……嗎?”Wouldyoulike后可接名詞或不定式。

如：Wouldyoulikeacupoftea?Wouldyouliketogoandseeher?

因此，如果我們說：“去游泳好嗎?”英語中可有這樣幾種表達(dá)法：

Shallwegoforaswim?

Let*sgoforaswim,shallwe?

Whatabout/Howaboutgoingswimming?

Whynotgoforaswim?

Wouldyouliketogoforaswim?

Whatdoyouthinkofgoingforaswim?

二、語法：

情態(tài)動(dòng)詞有can(could),may(might),must,haveto,shall(should,will(would),dare(dared),need

(needed),oughtto等。情態(tài)動(dòng)詞無人稱和數(shù)的變化；不能單獨(dú)使用，必須與其后的動(dòng)詞原形構(gòu)成謂

語

1.can,could

1）表示能力（體力、知識(shí)、技能）。

可用beableto代替。Can只有一般現(xiàn)在時(shí)和一般過去式；而beableto則有更多的時(shí)態(tài)。

Filnotbeabletocomethisafternoon.

2）表示請(qǐng)求和允許。

-----CanIgonow?-----Yes,youcan./No,youcan't.

3）表示客觀可能性（客觀原因形成的能力）。

They'vechangedthetimetable,sowecangobybusinstead.

Thishallcanhold500peopleatleast.

4）表示推測(cè)（驚訝、懷疑、不相信的態(tài)度），用于疑問句、否定句和感嘆句中。

Canthisbetrue?

2.may,might

1）表示請(qǐng)求和允許。mighttLmay語氣更委婉，而不是過去式。否定回答時(shí)可用can't

或mustn't,表示“不可以，禁止“。

1.——Might/MayIsmokeinthisroom?——No,youmustn't.

2.——May/MightItakethisbookoutoftheroom?

——Yes,youcan.（No,youcan't/mustn't.）

2）表示推測(cè)、可能性（不用于疑問句）。might不是過去式，它所表示的可能性比may小。

1.Hemay/mightbeverybusynow.

2.Yourmothermay/mightnotknowthetruth.

3.must,haveto

1）表示必須、必要。

Youmustcomeintime.

在回答引出的問句時(shí)，如果是否定的，不能用mustn't（禁止，不準(zhǔn)），而用needn't,don'thaveto（不

必）.

——Mustwehandinourexercisebookstoday?

第2頁

——Yes,youmust.——No,youdon'thaveto/youneedn't.

2）must是說話人的主觀看法，而haveto則強(qiáng)調(diào)客觀需要。Must只有一般現(xiàn)在時(shí)，haveto有更多

的時(shí)態(tài)形式。

1.Hisplayisn'tinteresting,Ireallymustgonow.

2.IhadtoworkwhenIwasyourage.

3）表示推測(cè)、可能性（只用于肯定的陳述句）

1.You'reTom'sgoodfriend,soyoumustknowwhathelikesbest.

2.Yourmothermustbewaitingforyounow.
