二、重点句型：
1. Today, both male and female athletes from around the world can take part, no matter what nation they come from.

no matter which=whichever不论哪一个，无论哪一个
no matter who=whoever不论谁，无论谁

3. I’m sure the whole of China must have felt proud when Xu Haifeng won the first gold medal for his country.
我相信，当许海峰为祖国赢得第一枚金牌时，整个中国准是为之感到自豪。
分析：句中“…must have felt…”为结构“must + have + done”，表示对过去发生的情况进行推测。
must可表示推测，用于肯定句，意为“想必，准是，一定是”。分两种情况：
①表示对现在情况进行推测时，用“must+动词原形”。
She must be ill. 她准是病了。
They must be at home now, aren’t they? 现在他们准在家，不是吗？
Look at his look! He must know the truth. 看他的表情！他准是知道真相。
②表示对过去情况进行推测时，用“must+have+过去分词”。
It must have rained last night. 昨晚天准是下雨了。
It must have rained. 天准是下雨了。
They must have seen the film last week. 上周他们准是看过那部电影了。
They must have seen the film. 他们准是看过那部电影。
He must have lived there for a long time. 他准是住在那儿很长一段时间了。
Tom must have been to Beijing. 汤姆以前一定去过北京。
注：1) 当must用于肯定句中表示推测时，其反意疑问句的构成为：若对现在情况进行推测时，反意疑问句用must后面的动词的一般现在时来构成；若对过去情况进行推测，句中有明确的过去时间状语，反意疑问句用didn’t来构成（若句中有be动词用wasn’t/weren’t）；若无明确的过去时间状语，反意疑问句用haven’t/hasn’t来构成。
She must be ill, isn’t she? 她准是病了，不是吗？
Look at his look! He must know the truth, doesn’t he?
看他的表情！他准是知道真相，不是吗？
It must have rained last night, didn’t it? 昨晚准是下雨了，不是吗？
It must have rained, hasn’t it? 天准是下雨了，不是吗？
They must have seen the film last week, didn’t they?
上周他们准是看过那部电影，不是吗？
They must have seen the film, haven’t they? 他们准是看过那部电影，不是吗？
He must have lived there for a long time, hasn’t he?
他准是住在那儿很长一段时间了，不是吗？
Tom must have been to Beijing before, wasn’t he? 汤姆以前一定去过北京，不是吗？
Tom must have been to Beijing, hasn’t he? 汤姆以前一定去过北京，不是吗？
2) 如果要表示否定的推测要用can/could not，意为“不可能，不一定”，不可用mustn’t，因为mustn’t意思是“不准，一定不要”。
The room is locked. She can’t be in. 房间上了锁。她准不在家。
His answer can’t be right. 他的回答不可能是对的。
They can’t have finished the work. 他们不可能完成了那项工作。
