情态动词的基本用法
情态动词是表示说话人的语气、情态等的一类词。如：can(能，会)、may(可以)，以后我们还将学到must(必须)、should(应该)、would(应该、想要)等。情态动词在运用时有以下三方面的特征：
1.
情态动词无主语人称及单复数的变化。
?They
can
play
the
piano.
?She
can
speak
a
little
English.
?You
may
watch
TV
after
supper.
2.
情态动词在句中运用时，后接动词原形。
?The
girl
can
sing
English
songs.
?I
can
play
Chinese
chess.
3.
含情态动词的肯定句变为一般疑问句时，将情态动词提至句首，后加＂?＂；变否定句时，在情态动词后加上＂not＂即可。
?This
boy
can
dance
well.
?—Can
this
boy
dance
well?
(一般疑问句)
—Yes,
he
can.
/
No,
he
can’t.
?This
boy
can’t
dance
well.
(否定句)
