課文分析
本單元的課文是一篇幽默故事。通過這個(gè)有趣的故事，對(duì)粗心大意的人和事進(jìn)行了含蓄的諷刺和批評(píng)，并通過它來教育學(xué)生克服粗心大意的不良習(xí)慣，養(yǎng)成嚴(yán)謹(jǐn)認(rèn)真、一絲不茍的作風(fēng)。
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.
下面的短文概括了這個(gè)幽默的主要內(nèi)容，可供復(fù)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.

reply, answer
reply既可作不及物動(dòng)詞，也可作及物動(dòng)同，還可作名詞。作不及物動(dòng)詞時(shí)，作“回答”，“答復(fù)”解，可用 reply to sth／sb.；作及物動(dòng)詞時(shí)，是“回答”，“回答說”的意思，后接直接引語或賓語從句；用reply作名詞時(shí)，作“回答”“答復(fù)”解，后可跟介詞to，表示“對(duì)……的回答\答復(fù)”。
answer作及物動(dòng)詞時(shí)，后面可直接跟名詞作其語，也可作名詞，作“答案”“回答”解，后面也可跟介詞to。

ring back, ring off，ring up
1）ring back意為“回一個(gè)電話”。back是副詞，其賓語是代詞時(shí)，要將這個(gè)代詞放在 back之前。
2）ring off意為“掛斷電話”。
3）ring up意為“給某人打電話”。其中 up是副詞，如有賓語，則將賓語放在up之前。如：

If you have any questions to ask me, please ring me up. 如果你有問題要問我，請(qǐng)打電話。
meeting, conference
二者都作“會(huì)議”解，其區(qū)別在于：
1） meeting指一般性會(huì)議，可用于任何場(chǎng)合。
2）conference是比較正式的用語，指就專門問題進(jìn)行研究或交換意見的會(huì)議或大型的會(huì)議。
We had a meeting thismoring．上午我們開了個(gè)會(huì)。

3）form指“構(gòu)成、形成”，強(qiáng)調(diào)所構(gòu)成的東西必須具有外形或具有一定的結(jié)構(gòu)或包含設(shè)計(jì)工作。

這組形容詞都可作“有趣的”解。
funny指由于有趣的行為、外表、性格或內(nèi)容而逗人發(fā)笑，也可指不尋常的事令人“難于理解”。如：
interesting“令人感興趣的”，表示主動(dòng)引起別人興趣。含有主動(dòng)意味。作表語時(shí)，主語通常是物；作定語時(shí)，可修飾人，也可修飾物。如：
I heard such a funny story this morning. 早上我聽了一個(gè)有趣的故事。
Zheng Jie has some interesting plans. 鄭杰有一些有趣的計(jì)劃。

重點(diǎn)講解
What a lot of invitations to send out！

The ship sent out a message for help．
“send out”與“give out”，“give off”同義，例如：

make oneself known（使……被了解），make oneself understood（使……被理解）等。例如：
Will you please make yourself known to us in English？
Her voice is so low that she can’t make herself heard．
Hold on , please. 請(qǐng)稍等。

—Hold on , please. I’ll go and see if he is in.

—請(qǐng)稍等，我去看他在不在。

①Please hurry up，there is someone waiting for you at the school gate．請(qǐng)快點(diǎn)，校門口有人等你。
②There must be some reason for him to be late again．想必有某種理由他才又遲到了。
語法---情態(tài)動(dòng)詞表示推測(cè)用法
用法：
1）must表示我們對(duì)某事很有把握，從邏輯上看是必然的，它只能用于肯定的陳述句中。在疑問句和否定句中，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．約翰說那位教授至少有70歲，但彼得認(rèn)為他不可能有那樣老。
②He can't have been to your home. He doesn't know your address．他肯定沒去過你家，他還不知道你的地址呢。
2）can和may表示推測(cè)時(shí)，語氣較弱。在肯定句中，can常用來表示客觀的邏輯上的可能性；而may表示事實(shí)上的可能性。如：
①Anyone can make mistakes．人人都會(huì)犯錯(cuò)誤。
②He looks pale. He may be ill．他臉色蒼白，可能病了。
在疑問句中，通常用can，不用may
－Can they have missed the bus? －Yes, they may have．
“他們會(huì)錯(cuò)過公共汽車嗎？”“是的，也許會(huì)�！�
3）can和may都可用于否定句，但含義不同。
can not表示“不可能”；may not表示“可能不”。
①She may not tell lies．她也許沒有說謊。
②He can’t be her father; he is too young. 他不可能是她的父親，他太年輕了。
例題：
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常用來表示禁止，不允許；may表示一種可能性；can’t 則用來表示否定意義的推測(cè)，意為“不可能”，它是一種非常有把握的推測(cè)。正確答案為B項(xiàng)。
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
說話者在找自己遲到的原因，并對(duì)過去的原因進(jìn)行推測(cè)。can不用于表示肯定的推測(cè)。should have done表示“本應(yīng)該做某事，但未做”，不合句意。所以答案為A項(xiàng)。
練習(xí)：
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
2. At present too many trees ______ still ______ cut down.
A. is, being B. are, to be C. are, being D. is. be
