[探究 情态动词can]
can 是情态动词，本身有一定的词义，意为“能，会”，但它不能独立作谓语，只能和动词原形一起构成谓语。情态动词can没有人称和数的变化。下面是can的各种句式变化：
(1)肯定句
主语＋________＋动词原形＋其他. 例如：
I can sing English songs. 我会唱英文歌曲。
(2)否定句
主语＋can＋not＋____________＋其他．(can＋not经常缩写为can't。) 例如：
I can't sing many English songs.
我会唱的英文歌曲不多。
can
动词原形
(3)一般疑问句及其答语
—_______＋主语＋动词原形＋其他？
—_______， 主语＋can./_______， 主语＋can't. 例如：—Can you draw a map of China
你能画一张中国地图吗？
—Yes, I can./No, I can't.
是的，我能。/不， 我不能。
Can
Yes
No
[拓展] can除表示能力外，还表示请求或许可，相当于may，多用在口语中，意为“可以，能”等。
(1)在疑问句中用来提出要求。“Can you…？”意为“请你……好吗？”，表示说话人的请求； “Can I…？”意为“我可以……吗？”，用来询问对方是否允许自己做某事(此时多使用may)。 在句末加上please显得更有礼貌。
(2)在否定句中表示“不可以，不可能”。例如：
You can't sit here.
你不可以坐在这里。
It can't be Li Lei's book. His is here.
这不可能是李雷的书。他的(书)在这里。
