Could you help me? You could talk to your teacher now. He couldn’t be at the school then. Could you please clean your room? 你能打扫一下你的房间吗？ 在表示请求帮助或请求允许的疑问句中，我们常用could代替can， 以表示礼貌、委婉或不确定的语气。不能把could 看作为can 的过去式。 1. could表示请求，语气委婉，显得有礼貌。 Could you please clean your room? 你可以打扫你的房间吗？ 肯定回答：Yes, I can. Yes, sure. / Yes, of course. 否定回答： Sorry, I can’t. I have to do my homework. 2. could表示请求许可，希望得到允许。 Could I go to the movies? 我能去看电影吗？ 肯定回答：Yes, you can. Yes, sure. 当然可以。 否定回答：No, you can’t. 不，不行。 Now make sentences using could and the following phrases. go to the movies 去看电影 2) stay out late 在外面待得很晚 3) use the car 使用汽车 4) get a ride 去骑车 5) use your computer 使用你的电脑 6) borrow some money 借些钱 7) invite my friends to a party 邀请我的朋友参加晚会 8) go to the store 去商店 9) use your CD player 使用你的CD播放器 3. could与can的区别 could与can都是情态动词，could是can的过去式。 二者都可用于表示请求，但是用法稍有不同。 can表示一般性的请求，语气随便，常用于熟人之间或长辈对晚辈、上级对下级的场合； e.g. Can you tell us your story, Tony? 你能给我们讲讲你的故事吗，Tony？ could表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈、下级对上级的场合。 e.g. —Could you tell us if it snows in
