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,带有感情色彩。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。
