情态动词must,
can,
could
表示推测
情态动词can,
could
表示“能够，可以”等意义,can,
could
还表示对现在或将来的推测。意为“会，可能”。
（1）can
表示推测时，往往用于否定句和疑问句。用于疑问句时，can
比could
表示的“可能性”要大；用于否定句时，can’t
表示“不可能”。
例如：You
can’t
be
serious!
你不是认真的吧！
（2）could
则可用于肯定句、否定句和疑问句，表示某事有可能发生或可能是事实
例如:
He
could
be
in
pain.
他可能很疼。
Can/Could
this
be
true
这有可能是真的吗？
（3）情态动词must
也可以表示猜测，意思为“一定、准是”，通常只能用于肯定句。
例如：Betty,
you
must
know!
贝蒂，你肯定知道！
辨析：
（1）Who
sent
the
present
Can
it
be
your
brother 是谁送来的礼物啊？会是你哥哥吗？（询问可能性）
（2）It
must
be
your
brother.
肯定是你哥哥。（语气强烈，表示非常肯定）
（3）It
can’t
be
my
brother.
His
still
in
France.
不可能是我哥哥，他还在法国。（表示不肯能）
2.
祈使句
表达说话人对对方的叮嘱、劝告、希望、禁止、建议、请求或命令等。祈使句一般以动词原形开头，无时态和数的变化。常见的句型如下：
1.
动词原形构成的祈使句
此类祈使句暗含的主语是you,
但通常省略。祈使句的句首或句末有时加please,
还可以加上称呼语，用逗号与句子主体隔开。例如：
Have
a
nice
day!
祝你度过美好的一天！
Come
this
way,
please.
请走这边。
Please
be
quiet,
boys!
男孩们，请安静！
Make
sure
he’s
warm.
确保他不受凉。
祈使句否定形式往往在句首加上do
not
(don’t
)
或never。例如：
Don’t
use
the
lift.
不要使用电梯。
Never
be
late
again!
再也不要迟到了！
2.
let’s
构成的祈使句
这类祈使句往往用于提出建议，例如：
Let’s
spend
this
weekend
in
the
countryside.
这周我们到乡下度周末吧。
祈使句否定形式是当祈使句表示邀请或建议(Let’s…)
时，则在Let’s与
do之间加not。
例如：Let’s
not
hurry.
我们不要太急。
3.
无动词祈使句
在请求、命令和口号中，常用无动词祈使句，它实际上是省略了动词，从而使祈使句更简洁有力。
例如：Just
a
minute,
please!
请稍等！
This
way,
please!
请走这边！
祈使句否定形式是句首加not.
例如：Not
there!
不是那儿!
