He’s seeing a doctor. No, he can’t. He has to have a guitar lesson. can和have to的用法 1. can可以表示能力, 意思是“能,会”, 在过去时中用could 。 2. can还可以表示请求许可, 在这一用法中, can和could都表示现在时态, 但could比can语气更加委婉。 can (could)用在一般疑问句中表示请求许可时,其肯定回答一般为 “Sure, I’d love to.”或“Yes, please.”;否定回答通常为“Sorry, I can’t.”。 3. can还可以表示可能性, 常用于否定句中。
4. have to意为“必须, 不得不”, 与must意义相似,
但 must强调人的主观意识, 而have to强调客观的必要。 have to变否定时要借助于助动词do, 表示“不必”。 5. can和have to后面都接动词原形。can没有人称和 数的变化, 而have to有。
用can或have to的适当形式填空。 1. ________ (can) you swim when you were 8 years old? 2.
—___________(can) I use your bike? ???? —Sure!
3. Mr Smith _________(can not) be at school. He left
