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。用于疑问句中用来提出要求，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；Can I...？“我可以……吗？”用来征求对方是否允许自己做某事。如在句末加上
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？
3. 表示可能。例如：
He can be at home now. 他现在可能在家。
The moon can’t always be full. 月亮不可能常圆。
4. 表示怀疑。在表达此意时，只能用于一般疑问句中，带有感*彩。例如：
Can it be true? 那会是真的吗？
二、 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 swim.
Emma can see the pen on the desk.→ Emma cannot see the pen on the desk.
2. 在变一般疑问句时，直接移到主语前（原主语的首字母改成小写，第一人称应变为第二人称）即可。例如：
I can see an orange on the table. → Can you see an orange on the table?
其回答可用Yes, OK或Certainly等作肯定回答；用No或Sorry等作否定回答。例如：
—Can you look after my books, please? 你能照看一下我的书吗？
—OK. 可以。
用Certainly回答。此时语气更为肯定。例如：
—Can I see your guitar? 我能看看你的吉它吗？
—Certainly. 当然可以。
[特别提醒] can与may都可以表示“许可”。在征求对方意见时用may较多。例如：May I go now? 现在我可以走吗？在询问客观上是否可以时，can则当仁不让。例如：Can we take the books out? 我们能把这些书拿出去吗？在两者都可以用时，may显得客气一些。例如：May I take this seat? 比Can I take this seat? 稍婉转一点。在陈述句中用我较多。例如：You can sit here. 你可以坐在这里。
can还可以表示能力，而may则无此用法。
