Grammar
情态动词can的用法
一、基本用法
1.表示能力（如体力和脑力方面），意
为“能；会”等。例如：
Can you speak English 你会讲英语吗？
Can you play the piano 你会弹钢琴吗？
2.表示请求或允许，多用在口语中，
意为“可以；能”等。用于疑问句中用
来是出要求，用于否定句表示不允许。
例如：
Can I help you 我能帮助你吗？
You can't play basketball.
你不能玩篮球。
Can you. “请你…好吗？”表示说话人的请求；
Canl. “我可以…吗？”用来征求对方是否允许
自己做某事。如在句未加上please一词就显得更有礼
貌了。
例如：
Can you help me,please
请你帮助我好吗？
句式变化如下：
1.在变否定句时，直接在can后加上“not”,可缩
写成can’t或cannot,但不能写成cann’t。例如：
He can swim.
-He can't/cannot swim.
Tony can see the pen on the desk.
-Tony can't/cannot see the pen on the desk.
