一、重要句型或语法
1、情态动词can与may
本课主要侧重学习can和may表请求和表猜测时的用法区别。当表请求时,may的语气更为委婉;当表猜测时,can要用can't形式,而且表达的是把握较大的猜测,而may则表示把握较小的猜测。如:
He can't have gone to Beijing, because I saw him on the street just now.
He may have been in Beijing, for I haven't seen him since yesterday.
二、课文主要语言点
'The play may begin at any moment,' he said.1)句中的may表示对将来时间的猜测,所以采用的是may do的形式。 2)at any moment,随时。
'It may have begun already,' Susan answered.1)句中的may表示对过去时间的猜测,苏伊采用的是may have done的形式。 2)句中的already一反常规,放到句末,起到了强调作用,说明Susan想强调自己的猜测的把握度较大。
I hurried to the ticket office.1)hurry to+地点,赶到什么地方。 2)the ticket office,售票处。
'May I have two tickets please?' I asked. 'I'm sorry, we've sold out,' the girl said.1)句中的May I...语气比Can I...更委婉,显得更礼貌。 2)have表示购买,相当于sell。 3)句中的we've sold out后面省略了all the tickets。sell out,卖完。
'What a pity!' Susan exclaimed.1)可复习what和how引导的感叹句。 2)pity,可惜、遗憾之事。 3)exclaim,大声说、感叹。
Just then, a man hurried to the ticket office.just then,正在这时。一般用在句首开头,用逗号隔开。
'Can I return these two tickets?' he said. 'Certainly,' the girl said.1)句中的can表请求。 2)return,退回。
I went back to the ticket office at once.1)go back to,回到,相当于return to。 2)at once,立即、马上,相当于immediately。注意,at once也可以表示同时的意思。
'Could I have those two tickets please?' I asked. 'Certainly,' the girl said, 'but they're for next Wednesday's performance. Do you still want them?'1)Could I...,表情求,语气较为委婉,相当于May I...。 2)performance,演出。源自动词perform,表演。
'I might as well have them,' I said sadly.might as well,不妨、还是...好。语气比may as well更为委婉。
三、读写重点
注意助动词或系动词的缩略形式,注意识记其缩略形式。但是,需要切记的是:一般来说,在书面写作中,尽量不要采用缩略形式,以免显得不够严谨规范。
四、语用文化
可让学生讨论自己一次特别的观影经历。
五、教学建议
1、当对比can和may表猜测时,连同must表肯定猜测一起讲。
2、可借此机会复习一下情态动词can/may/must的常见用法。
