课文分析
本单元的课文是一篇幽默故事。通过这个有趣的故事，对粗心大意的人和事进行了含蓄的讽刺和批评，并通过它来教育学生克服粗心大意的不良习惯，养成严谨认真、一丝不苟的作风。
Part1 (Paragraph 1 ) Dr Baker accepted the invitation to the 199. . .Medical Conference in London.
Part 2 (Paragraphs 2—10) Dr Baker was surprised to be asked to give a talk on DNA, which he knew nothing.
Part 3 (Paragraphs 11—18) Someone had made a careless mistake by writing Dr D. Baker instead of Dr Peter Baker, and Dr Baker gave a talk on ENT.
下面的短文概括了这个幽默的主要内容，可供复述：
Dr Baker was very much surprised to receive an invitation to the 199. . . Medical Conference in London. However, he decided to attend the meeting himself. On the morning of the second day of the conference , the main speaker failed to arrive because of the bad weather at the airport. So he was asked to give a talk instead. When the organizer asked him to give a talk on DNA, Dr Baker told him that he was an expert on ENT. Later the organizer discovered the mistake. Though the organizer had put Dr P. Baker's name on the list of speakers, when the invitation list was being done, someone had made a careless mistake and had written “Dr D. Baker” instead. Anyhow Dr Baker did give a talk that day and everyone at the conference was very interested in it.

语法---情态动词表示推测用法
用法：
1）must表示我们对某事很有把握，从逻辑上看是必然的，它只能用于肯定的陈述句中。在疑问句和否定句中，通常用can和can’t。
①John said the professor must be at least seventy, but Peter thought he couldn't be as old as that.约翰说那位教授至少有70岁，但彼得认为他不可能有那样老。
②He can't have been to your home. He doesn't know your address.他肯定没去过你家，他还不知道你的地址呢。
2）can和may表示推测时，语气较弱。在肯定句中，can常用来表示客观的逻辑上的可能性；而may表示事实上的可能性。如：
①Anyone can make mistakes.人人都会犯错误。
②He looks pale. He may be ill.他脸色苍白，可能病了。
在疑问句中，通常用can，不用may
－Can they have missed the bus? －Yes, they may have.
上一页 [1] [2] [3] [4] [5] 下一页
“他们会错过公共汽车吗？”“是的，也许会。”
3）can和may都可用于否定句，但含义不同。
can not表示“不可能”；may not表示“可能不”。
①She may not tell lies.她也许没有说谎。
②He can’t be her father; he is too young. 他不可能是她的父亲，他太年轻了。
例题：
Michael________ be a policeman, for he’s much too short.
A. needn’t B. can’t C. may D. mustn’t
分析
needn’t表示“不必”；mustn’t常用来表示禁止，不允许；may表示一种可能性；can’t 则用来表示否定意义的推测，意为“不可能”，它是一种非常有把握的推测。正确答案为B项。
Sorry I’m late. I_______ have turned off the alarm clock and gone back to sleep again.
A. might B. should C. can D. will
分析
说话者在找自己迟到的原因，并对过去的原因进行推测。can不用于表示肯定的推测。should have done表示“本应该做某事，但未做”，不合句意。所以答案为A项。
练习：
1. —The light is still on. Mrs Li ______ be in the office.
—She ______ be there because I saw her go home just now.
A. must, may B. may, mustn't C. must, can't D. can, may not
