三、总结(引深探究
15分钟)
语法重点:一、情态动词can的用法
can是一个常见的情态动词,表示说话人的语气或情态,基本意思是“能;
会”。它没有人称和数的变化,在句子中不能单独作谓语,其后必须跟实义动词原形。can的否定形式为can
not/can't/cannot;过去式为could,其过去否定形式为could
not/couldn't。
情态动词can有以下常见用法:
1.
表示能力:情态动词can一般指体力、知识、技能等方面的能力,即“能够;会”。
My
brother
can
swim
but
I
can't.
2.表示许可:多用在口语中,表示请求或允许,意为“可以;能够”等。用于疑问句中用来提出要求,用于否定句中表示不允许。
Can
I
use
your
pen?
3.表示推测:情态动词can表示推测时,常用于否定句或疑问句,意为“(不)可能”。用于肯定句中表示理论上的可能性,意为“有时会”。
It
can
be
very
cold
here
in
spring.
表示邀请:情态动词can除了表示能力、许可或猜测之外,还可以表示邀请;could较can更礼貌、委婉。情态动词can表示邀请时的用法如下:
(1)当用情态动词can发出邀请时,用一般疑问句Can+主语+动词原形+其他?
(2)当用情态动词can发出邀请时,其回答分为两类。一类表示接受邀请,另一类表示拒绝邀请。
总结:情态动词有:may/might,
can/could,
must,
have
to,
shall/
should,
will/would,
ought
to,
need,
dare,
used
to
特点:1.不能独立作谓语,只能和动词原形一起构成谓语,表示说话人的语气和情态。
2.
没有人称和数的变化。
(have
to除外)3.
否定形式:在其之后加not
(have
to除外)。
疑问形式:情态动词提到主语之前(have
to
除外)。
二、情态动词have
to
与
must的用法
have
to的意思是“必须、不得不”,
往往强调由于客观原因而必须做某事。have
to
后接动词原形;have
to有人称、数和时态的变化,
其第三人称单数形式为has
to,
其疑问形式和否定形式要借助于助动词do或does来完成。
We
have
to
look
after
our
sister
at
home.我们不得不在家照顾我们的妹妹。
Does
he
have
to
get
up
early
tomorrow
morning?
明天早上他必须早起吗?
I
don’t
have
to
stay
at
home
today.今天我不必呆在家里。
区别have
to
与
must:
二者都有“必须”之意,但
have
to
表示“客观上的需要”,有人称和时态的变化,否定形式为
don’t
/
doesn’t
/
didn’t
have
to
(没必要);must
表示“主观上的要求”,无人称和时态的变化,否定回答一般用
needn’t
或
don't
have
to
(不必)。must
否定形式为mustn't,表禁止,意为“一定不要,千万别;不许”。
We
have
to
wear
warm
clothes
in
winter.冬天我们不得不穿上暖和的衣服。(客观需要)
I
must
finish
my
homework
first
before
I
watch
TV.看电视前我必须先完成作业。(主观要求)
You
don't
have
to
tell
him
about
it.你不一定要把此事告诉他。
You
mustn't
tell
him
about
it.
你一定不要把这件事告诉他。
—Must
I

—Yes,
you
must.
/
No,
you
needn't.
