三.语法学习
1.I used to listen to rock music but now I collect telephone cards and paintings. (Page 53) 我过去常听摇滚乐,可现在我集电话卡和画。
used to do sth. 这一结构表示过去的习惯(过去经常反复发生的动作)或状态(暗含的意思是现在已不复存在),只有一种形式,即过去式,用于所有人称。used to的否定形式为:used not to do或didn’t use to do。疑问句为Used you to... ? 或 Did you use to...?如:
1)I used to go to school on foot.
我过去步行上学。(暗含的意思是:我现在不再步行上学了。)
2)Mary used to sleep late.
玛莉过去总是很晚才睡觉。(暗含的意思是:玛莉现在睡觉不再那么晚了。)
3)I used to walk along the road after supper.
我过去常常在晚饭后沿着这条马路散步。
4)He used not to like Peking opera, but now he’s very fond of it.
他过去不喜欢京剧,但现在非常喜欢。
现在大多数人在口语中或不太正式的书面语中对否定句和疑问句常使用与do 连用的形式。例如: 1)I didn’t use to like skating, but now I like it very much.
我过去不喜欢滑冰,但现在很喜欢。
2)Did you use to go there?你以往常去哪儿?
3)There used to be a theatre here, didn’t there?以前这里有一座剧院,是不是?
另外,注意be used to doing sth.与used to do sth.的区别:
be used to doing sth “习惯于……,适应于……”如:
1)He is used to working hard. 他习惯于努力地工作。
2)He used to bring me roses when he came to see me. 过去他来看我时,常带玫瑰花。
3)I’m used to doing jogging in the morning now. 我习惯于早上慢跑。
be used to do sth.“某物被用来做某事”。如:
1)Wood is used to make paper. 木材被用来生产纸张。
2)Computers can be used to do a lot of work now. 如今电脑可用来做许多事。
2. Collecting stamps must be great fun!集邮肯定很有趣!
must在这里是情态动词,作用是用来表示推测,可以翻译为“想必”。如:
1)Your brother must be in the school. I saw him just now.
你的哥哥想必在学校。我刚才看见他了。
2)Your friend must have left for Nanjing yesterday.
你的朋友想必昨天已经离开去南京了。
3) She thought that her present must be in the box.她以为礼物一定是在盒子里。
4) You must be thirsty after a long walk.走了很长的路,你一定渴了。
5) It must be ten o’clock now.现在肯定有10点钟了。
情态动词must的三种否定形式
must表示“必须”时,其否定回答为don’t have to,意思为“不需要”。如:
1)Must I pay back the money right now? No, you don’t have to.
我必须现在偿还这笔钱吗?不,你不需要现在还。
2)You must listen to the teacher carefully in class.
