3情态动词must，can，need

情态动词must,

can和need无人称和数的变化，不能单独使用，后面必须要跟动词原形。

（1）must表示“必须，一定要”，可用于肯定句、否定句和疑问句。否定形式must

not,缩写为mustn’t，表示“不能、禁止”的意思。例如：

In

my

home

town,

people

say

you

mustn’t

do

any

cleaning

on

the

first

day

of

the

Spring

Festival.在我的家乡，据说大年初一不能打扫卫生。

You

must

only

use

red

paper

for

hongbao

because

red

means

luck.你必须用红纸做红包，因为红色代表幸运。

【辨析】must

与

have

to的区别：

两者都表示“必须”，must强调说话人的主观看法，认为有必要或者有义务去做某事；have

to强调客观需要，表示“不得不”做。例如：

People

must

follow

the

traffic

rules.人们必须遵守交通规则。

I

have

to

stay

at

home

because

it’s

rainy

outside.我不得不待在家里，因为外面下雨了。（2）can作情态动词，有以下几种用法：①can用于表示能力，意为“能，会”，可以用beableto替换。例如：IcanspeakFrench.=I’mabletospeakFrench.我会说法语。②can用于表示客观可能性，意为“可以，能够”。例如：ComputerscanhelpusstudyEnglish.电脑可以帮助我们学习英语。③can用于表示允许，意为“可以”，与may相似。例如：Can/MayIhavealookatyourphoto我可以看一下你的照片吗？Youcan’tputthebookhere.你不能把书放在这里。（没有禁止的含义）

④can用于表示推测，一般用于否定句和疑问句，表示有把握的推测，意为“肯定不；不可能”。例如：

He

is

in

poor

health.

He

can

be

ill

at

any

time.

他身体不好，随时都可能会生病。

It

can’t

be

Sally.

She

is

in

Shanghai

now.

肯定不是萨丽，她已经去了上海（还没回来）。（3）need表示“需要，必须”。有两个用法：①作实义动词，后面可以跟名词、动词不定式、动名词。needtodosth.意为“需要做某事”；needdoingsth.意为“需要被做某事（表示被动）”。例如：Doyouneedanyhelp你需要帮助吗？Ineedtogetsomesleep.我需要睡会儿觉。Thisshirtneedswashing.这件衬衣该洗了。【注意】need作为实义动词时，否定形式为don’tneed。

②作情态动词，后面要跟动词原形。例如：

You

need

finish

your

homework.你需要完成你的作业。

He

need

clean

his

room

at

the

weekend.他需要在周末打扫他的房间。

【注意】need作为情态动词时，否定形式为needn’t。

there

are

some

differences

between

China

and

America

in

life.

you

call

them

aunt

or

uncle.

Second,

prepare

a

small

gift

for

the

Give

it

Third,
