知识要点导学
1. British women can show their hair, although many people wear a hat when it’s cold.
英国妇女可以把他们的头发展示出来，尽管天气冷的许多人戴着一顶帽子。
1） although 连词，意为“虽然，尽管”，相当于though, 如：I don’t really enjoy sports , though/although I did watch the game.我并不太喜欢体育，但我的确看过这场比赛。Though/Although she joined the company only two years ago, she’s already been promoted twice. 尽管她一年前才加入了这个公司，但已两次升职。
2） 注意although, though, but三词在句中的用法有所不同，although, though是从属连词，意为“虽然，尽管”，引导让步状语从句。but 是并列连词，意为“但是”，表示转折。汉语中习惯成对地使用“虽然…但是…”, 但英语中although, though 不可以与but连用，但可以与yet 连用。类似的还有because与so 也不能并用。如: Though he was only twelve, he could run faster than any kid in the school.= He was only twelve, but he could run faster than any kid in the school.尽管他才12岁，他却比学校里的任何孩子跑得都快。
2.情态动词can和must的用法
1）can 的用法：① 表示能力，意为“能，能够，会”，如：I can speak English. 我会说英语。②表示请求、许可，意为“可以”，相当于may。如：Can I use your pen? 我可以用一下你的钢笔吗？③表示推测，用在否定句中，意为“不可能”。如：It can’t be Jim’s book. His book is new. 这一定不是吉姆的课本。他的课本是新的。
2）must 的用法：①表示必须做某事，意为“应该，必须”。如：You must clean your bedroom every day. 你必须每天打扫卧室。② 回答以must 开头的疑问句时，否定回答用needn’t或don’t have to, 意为“不必”。如：-Must I do my homework now? –我现在必须做作业吗？-No, you needn’t/don’t have to. 不，你不必。③表示禁止某人做某事时，用mustn’t 。如：You mustn’t play in the street. 你不能在街上玩耍。④ must还可以表示推测，用在否定句中，意为“不可能”。如：It can’t be Jim’s book. His book is new.这一定不是吉姆的课本。他的课本是新的。
