Grammar
Focus
can可表示能力/允许/可能性/怀疑猜测，意为“可以，会，能”；
can’t意为“不会，不能，不可以”，还有“不可能”之意。
could为can的过去式，用法与can类似，常用于过去时态中；
can
could还可用于现在时态中表示委婉客气，相当于can；
could也可表示惊讶怀疑，不相信。
eg:
He
couldn’t
be
a
thief.
may表示允许、也许，意为“也许；可能；可以”，语气不太可能。
对may的一般问句的回答：
肯定回答一般是：Yes,
please./
Certainly./
Sure等
否定回答一般是：
No,
you
can’t/mustn’t.
may
might是may的过去式，与may用法类似，语气比may弱，表示推测的可能性更小，常用于肯定句和否定句中，不用于疑问句中。
must表示必须要做的事，意为“必须，应该”。
must一般问句的否定回答用needn’t或don’t
have
to，而不用mustn’t，mustn’t意为“不可以，不能”，表示禁止，不许可。
must
eg:
—
Must
we
hand
in
our
exercise
book
today?
—
Yes,
you
must.
(
No,
you
needn’t.)
must还可表示有把握的推测，意为“一定、肯定”。
must的过去式还是must。在回答以must开头的一般疑问句时，否定式需用needn’t，表示“不必”的意思。
