一.目的与要求：掌握本单元出现的单词和词组。如：repeat, funny, lady, joke, attention, unable, world－famous, introduction, college, note, organize, medical, attend, organizer, gentleman, suppose, earn, conference, expert, throat, sent out, get through, ring back, out of breath, make up等。
二.学会本单元出现的日常交际用语。
Can you ring up …?The line is busy.Could I speak to …, please ?
Can I take a message ?Can you ask …to ring me back, please ?
I can’t get through.I’ll try again later, Hold on please.
This is …speaking.I’ll ask …to call you.
三.本单元知识重点与难点分析：
1.在“1 Dialogue”中有这样一段对话：
Mary：What a lot of informations to send out!
要发出去的请柬可真多呀！
Lizzy：Yes, there must be over two hundred here.
是的，这儿想必有200多份。
句中的“must”作“想必”、“准是”、“一定”解，用来表示我们对某事有把握的推论或揣测。虽然句中must也可用may来代替，但must语气更为肯定。例如：
They must be very tired now, for they have been working the whole morning.
他们现在一定是非常累了，因为他们整个上午都在工作。
I often meet him in this street.He must live quite near here.
我经常在这条街上碰到他。想必他就住在附近。
“Can you tell me where LiLi is ”“He must be is the teachers office.”
你能告诉我李立在哪儿吗？ 他肯定是在老师办公室。
must表示推测的这种用法通常用在肯定句中，在疑问句中常用can(可能)，在否定句中常用can’+(不可能，不会是)，而不用mustn’t。例如：
Somebody is knocking at the door.Who can it be ? It must be Wang Hong.
No, It can’t be Wang Hong, because she left for Shanghai this morning.
有人在敲门。会是谁呢？一定是王红。不，不会是王红，因为她今天早晨就动身去上海了。
That can’t be the postman───it’s only seven o’clock.
那不会是邮递员──现在才7点钟呢。
She must be a professor.No, she can’t be a professor—she is so young.
她一定是个教授。不，她不可能是个教授──她还这么年青。
2.“An invitation to the 199…Medical Conference in London.”
“一份邀请参加199 年在伦敦召开的医学大会的请柬。”
1)在“the 199…Medical Conference”中的年份用了省略号，这是留给教师上课时灵活处理的，如是1997年上这一课，你就把7填上；如果是1998年上这一课，你就把8填上，依此类推。
2)注意“invitation”的搭配：
A.和动词的搭配
accept an invitation接受邀请
give sb an invitation邀请某人
receive an invitation收到请贴/接到邀请
refuse sb’s invitation拒绝某人的邀请
send out an invitation发出请贴/邀请
B.和介词的搭配
at the invitation of sb应某人的邀请
an invitation to(an activity)参加(某种活动)的邀请。
an invitation from sb来自某人的邀请。
例如：I received an invitation from Peter to his birthday party.
我收到皮特请我去参加他生日聚会的请帖。
Mr Baker accepted the invitation to the Medical Conference.
贝克先生接受了去参加医学大会的邀请。
Mr Martin refused Mary’s invitation to her wedding.
马丁先生拒绝了玛丽请他参加她的婚礼的.邀请。
She sent out many invitations to her wedding but she hasn’t received any reply to them.
她发出了许多参加她婚礼的请柬，但还没有收到任何答复。
3.Dr Baker replied to the invitation, accepting it.
贝克博士答复了请柬，接受了邀请。
1)“accepting it ”是现在分词短语作状语，表示伴随动作，相当于“and accepted it ”。
例如：
The children entered the classroom, singing and dancing.
孩子们唱着、跳着，走进了教室。(表示伴随状态)
He ran up to us breathing heavily.他气喘吁吁地向我的跑来。(表示伴随状态)
The boss went to see Mr King, praising him for his excellent work.(……，and wondered why he had been invited)贝克博士躺在床上，对于为什么他会受到邀请，心里感到很纳闷。
2)注意accept和receive的区别：
receive作“收到”解，只表示客观上“收到某物”，而accept作“接受”解，表示主观上“乐意接受某物”，如果说：“I received an invitation.”则表示“我接受了邀请”，我准备去。例如：
He received the gift, but he didn’t accept it.他收到了礼物，但是他没有接受。
I have received an invitation from Peter.Shall I accept it or refuse it ?
我收到了皮特的请柬，我是接受还是拒绝呢？
3)reply在句中用作不及物动词，作“回答”解，常用reply to sb/sth，表示“对……作出回答”，作及物动词时，是“答道”，“回答说”的意思，后跟直接引语或宾语从句。作名词时，作“回答”、“回信”、“答复”解，例如：
She cried, but didn’t reply.她哭了，但不回答。
Please reply to my question at once.请立刻回答我的问题。
“Certainly, not ”she replied.“当然不行”她答道。
He replied that he didn’t know the secret.他回答说，他不知道这个秘密。
She didn’t lift her head, and made no reply.她头也不抬，也不回答。
answer和reply都可用作及物动词，作“回答”解，但answer可跟名词作宾语而reply只能跟直接引语或宾语从句，如跟名词，reply后须加to。例如：
Can you answer my question ?你能回答我的问题吗？(也可说Can you reply to my question?)
4.If Dr Baker is in the hall, will he please make himself known to me ?
如果贝克博士在会场的话，请他向我自我介绍一下好吗？
make oneself known to sb.意思是“向某人作自我介绍”。例如：
They are all my friends.Will you please make yourself known to them ?
他们都是我的朋友。请你向他们自我介绍一下好吗？
5.Would you mind giving a talk today about DNA ?
能不能请你今天作一个关于DNA的报告？
“Would you mind doing sth.”是一个日常交际用语，表示礼貌地提出请求。例如：
Would you mind opening the window ?请你把窗户打开好吗？
Would you mind fetching me some water, please ?请你给我打点水来好吗？
Would you mind sending him a message for me ?请你帮我带个口信给他好吗？
6.You must be joking!你一定是在开玩笑吧！
must表示推测，作“一定”“想必”解。must后用现在进行时be joking，表示此刻正在进行的动作。例如：
Where are they ? They must be playing football on the playground now.
他们在哪儿呢？他们一定是正在操场上踢足球了。
It’s ready seven o’clock.She must be waiting for you in her house now.
已经7点，她肯定是正在家里等你呢。
7.That may be so.这是有可能的。
情态动词“may”在句中作“可能”解，也具有推测的含义，但语气不像must那样肯定。例如：
He may be right.他可能是对的。
They may come here tomorrow.他们明天可能会到这里来。
She may be still waiting for us.她可能还在等我们呢。(比较：She must be still waiting for us.他一定还在等我们。)
8.“There must be some mistake,”said Dr Baker.贝克博士说，“准是出了什么差错了。”
句中some作“某一个”解，常用在单数普通名词前，表示未知的，或说话者不愿特别说明的人、地、物等。例如：
Some man at the door is asking to see you.门口有人要见你。
She won a competition in some newspaper or other.她在某报举办的比赛中获胜。
For some reason she didn’t come to school yesterday.由于某种原因，她昨天没来上学。
They plan to visit China some time near year.他们计划在明年的某个时候访问中国。
He must be living at some place not far from here.
他一定是住在离这不远的某个地方
9.“ENT? What does that stand for ?”asked the organizer.──“Illnesses of the ear, nose and throat…”ENT? 它代表什么？组织者问道。──“代表耳、鼻喉科的疾病……”stand for作“代表”解，本句的完整回答是：“It stands for illness of the ear, nose and throat.”ENT是ear, nose, throat。3个词的第一个字母组成的缩略语，这种省略语不管是一个字母或多个字母，当其作主语时，都作单数看待，谓语动词要用单数。例如：
What does C stand for in“37℃”？──It stands for centigrade.
“37℃”中的C代表什么？──代表摄氏(寒暑表)。
UN stands for the United Nations.UN代表联合国。
10.Dr lively was going to talk on that very subject today.
莱芙利博士今天原打算要读的正好是这个题目。
1)介词on在句中作“关于”(about)解。例如：
Have you any idea on that problem ?关于那个问题，你有什么想法。
Dr Baker was asked to give a talk on DNA.
贝克博士被邀请做一个有关DNA的报告。
I can’t agree with you on this point.关于这一点，我不能同意你的意见。
2)句中的very是形容词，修饰后面的名词subject，用来加强语气。作“正好”、“就是”解。
This is the very thing I need.这正是我需要的东西。
He is the very person we are looking for.他正是我们要找的那个人。
She determined to go that very afternoon.她决定就在当天下午走。

一、教法建议
【抛砖引玉】
单元双基学习目标
Ⅰ . 词汇学习
send out , get through , ring back , repeat , funny , lady , attention , unable , world - famous , serious , introduction , college , joke , note , organize , medical , attend , organizer , gentleman , earn , suppose , out of breath , conference , a . m . , p . m . , make up , expert , throat

9 . Can you ask … to ring me back , please ? 10 . I'll ask … to call you .
Ⅲ . 语法学习
情态动词 must , may , might , can't , could …
这些情态动词常用来表示推测。
1 . must 用于肯定句，作“准是；一定是；一定是；相必是”解，对当前发生的情况作出非常肯定的推测。
must 用来表示有把握的肯定推测， ( 否定推测用 can't , 不能用 mustn't ) 其推测原因往往是根据某项客观存在的条件产生的。
The man talking to the students in the classroom must be a teacher .
2 . can't 或 couldn't 作“不可能，想必不会”解，以对当前发生的事作出否定的推测，表示出惊异，怀疑的情绪。
He can't be waiting for us at the school gate since he is ill .
3 . might , may , could 用于肯定，但它表示一种不太肯定的说法。译成“也许；可能”。这几个词同 must 相比，表示“无客观条件线索”的推测。
She might ( may , could ) be in the classroom .
【指点迷津】
怎样用好SUPPOSE
※ 想，认为 ( = guess , think ) 。
1 . 后接从句。
I suppose we're too late to catch the 9 : 30 train .
John supposed that he could find a job soon .
I don't suppose it's the rush hour yet .
I don't suppose she'll agree with us on the matter .
2 . 后接名词／代词 + 不定式 ( 不定式多为 to be ) 。
I suppose him to be around fifty . ( = I suppose that he is around fifty . )
She is supposed to be an expert in this field .
The work is not as simple as it was supposed to be .
这里值得注意的是 be supposed to… , 常常表示“应该……”。
He is supposed to be here on time .
We are supposed to help each other .
We are not supposed to smoke on the bus .
3 . 与 so , not 连用。
- Will she come with us ?
- Yes , I suppose so .

4 . 用于插入语。
You don't mind my smoking here , I suppose .
What do you suppose is the right way out of difficulty ?
※ 假定，设想 ( = be thought , take it as a fact ) 。
1 . 后接名词／代词 + 不定式 ( 不定式为 to be ) 。
Suppose the poor girl to be your daughter . ( = Suppose that the girl is your daughter . )
Let's suppose the news to be true . ( = Let's suppose that the news is true . )
2 . 后接从句。常用 Suppose… 或 Let us suppose … 的句式。
Suppose the earth is flat .
Let us suppose that his statement is right .
此句型常用来表示建议，意思是“……怎么样 ? ”，“何不…… ? ”
Suppose we put off the meeting till tomorrow .
Suppose we go for a picnic tomorrow .
另外，suppose／supposing 置于句首时可表示条件，意思是“假如”，“万一”，“倘若”等，相当于 if。
Suppose／Supposing it rains tomorrow , what shall we do ?

1 . A minute , please . 2 . Just a minute .
3 . Just a moment . 4 . One moment , please .

Dr Baker got up and went over to the organizer .

They went over their lessons together at night .
Would you mind going over this work for me ?
单元难点疑点思路明晰
1 . Will he please make himself known to me ? 请他向我自我介绍一下好吗 ?
make oneself known to sb . 是“向某人作自我介绍。”类似用法还有：make oneself heard ( 使别人听到自己的声音 ) , make oneself understood ( 使别人懂得自己的意思 ) 等。例如：
When you speak English , be sure to make yourself understood .
I didn't succeed in making myself understood .
She couldn't make herself heard .
He made himself heard across the room .
You must make yourself respected .
2 . Dr Baker replied to the invitation , accepting it . 贝克博士还是答复了请柬，接受了邀请。
accepting it 是现在分词短语，表示伴随动作，相当于 and accepted it , 又如：
He ran up to her breathing heavily .
My train starts at six , arriving in Beijing at ten .
注意同义词 accept 与 receive 的区别：
receive ( 收到，得到 ) ，只表示客观的收到某物，与主观愿望无关。
accept ( 接受 ) 表示主观上乐意接受。如：
I received his offer , but did not accept it .
He received an invitation to the party and was glad to accept it .
3 . Will : Does she have your number ? 威尔：她有你的 ( 电话 ) 号码吗 ?
Mary : Perhaps not . It's 6674044 .
玛丽：也许没有。我的号码是 6674044 .
Perhaps not 是一个否定式的省略句。从上文来看，它应是“Perhaps she doesn't have my number . ”的省略。类似的否定性省略还有：
Of course not／Certainly not／Surely not 等。
这种省略的肯定式为：Perhaps so 也许是／Quite so 确是这样／Just so 正是这样／Certainly ( 当然是 ) 等等。例如：
Do they have lunch at school ?
Perhaps so ( not ) ／Certainly ( not ) .
Will you be free tomorrow ?
Of course ( not ) ／Perhaps so ( not ) .
4 . There must be some mistake . 准是出了什么差错了。
some 在此处的意思是“某一个”，用在单数名词前，表示未知的或说话者不愿特别说明的人、地、物等。例如：
Some person at the door is asking to see you .
I remember having read that article in some magazine .
I hope you'll come to see me some afternoon .
There must be some reason for what he's done .
We expect him back some time next week .
I suggest that we go to some park to spend our weekend .
5 . Would you mind giving a talk today about DNA ? 今天能否请你做一个关于 DNA 的报告 ?
Would you mind doing sth . ? 是一个日常交际用语，表示礼貌地提出请求。
注意在回答中，要对 mind 进行回答，因此“No”，是“不介意”，也就是同意做；而“Yes , ”“I'm afraid . . . not”则是“介意”，也就是不行。
- Would you mind opening the door for me ? 请你帮我打开门好吗 ?
- No , of course not . ／I'm afraid I can't . 当然可以。／恐怕不行。
6 . You must be joking !
你一定是在开玩笑吧 !
joke 既可作名词用，表示“笑话”、“玩笑”，也可作动词用，表示“开玩笑”、“说笑话”。本句 ( You must be joking ) 实际上是表示不相信，且含有讥讽的意思。例如：
I was only joking .
He likes to joke with us about something in his family .
Don't play a joke on me .
I only said it for a joke .
7 . You can't be serious ! 你该不是当真的吧 !
serious 形容词，作“严肃的”、“认真的”解 ( = no joking ) 解。情态动词 can , 也可表示揣测，但主要用于疑问句和否定句。试比较：
You must be serious .
Can you be serious ?
8 . Dr Peter Baker is an expert on DNA , and I'm an expert on ENT . 彼得贝克博士是 DNA 专家，而我则是 ENT 专家。
be an expert on “是…方面的专家”。介词 on 表明具有某方面的专业知识。例如：
His father is an expert on Chinese history .
He is an expert on foreign affairs .
expert 后有时接介词 at／in , 表示擅长某种技能。例如：
My mother is an expert at／in cooking .
He is an expert at medicine .
9 . I'm doing research in ENT at Lincoln College in Tennessee .
do research in／on 从事……研究工作。例如：
He has done a lot of research on that subject .
He is famous for doing his researches in electricity .

12 . I ____ a talk with her , but I was too busy then .
A . must have had B . should take C . should have had D . may take
答案及精析： 1 . C。could 用于疑问句，表示请求，语气委婉，答语必须用 can。2 . C。may 用于疑问句，表示请求，否定回答要用 mustn't , 表示“不可以”、“禁止”、“阻止”之意。3 . B。句中第一句说明“老师正在工作”，因而说“你绝对不可大声吵闹。”mustn't 表“绝对不可”。4 . D。need 作为情态动词的疑问词，其肯定回答一般用 must。其否定回答为“needn't”。5 . A。回答 must 引出的问句时，如果是否定的回答，不能用 mustn't ( mustn't 表示绝对不可 ) ，而要用 needn't 或 don't have to。6 . C。“must be + 表语”结构表示体力或脑力方面的能力。A 项时态不对，C 项本身错，D 项中 can 与 be able to 不连用。8 . C。can 表示“能力”而 be able to 表示经过一番努力才达到目的。从 He worked very hard 判断，应选 C。9 . B。must 表示谈话双方主观上认为“有义务”、“有必要”去做某事，而 have to 表示客观需要。另外 must 一般不用于过去式句中，但可用在间接引语中。10 . C。对过去发生的事情的推测，要用“can／could + have + 过去分词”。11 . B。对过去发生的事情的疑问推测也用“can／could + have + 过去分词”。12 . C。对“过去本该做而没有做的事情”的表达，一般用“should + have + 过去分词”，也可用“ought to + have + 过去分词”。

12 . This is the new biology lab where we visited last year .
答案与简析：
1 . belong 表示“属于”，是不及物动词，常与介词 to 连用，不能用被动语态，应把 was 去掉。 2 . 表示一个动作正在进行时，突然又发生了下料想不到的动作，须用并列连词 when，意为“那时”、“这时” = and then , 应把 while 改成 when。 3 . used to do sth . 表示“过去常常……”，和现在对比，现在不这样了；be used to sth . ( doing sth . ) 表示“习惯于……”，可用于各种时态。该句主句谓语动词的用法属于前者，应把 used 前的 was 去掉。 4 . 该句 It 为形式主语，真正的主语是置于句子后部的 to get to the top of a company。该句是指做某事困难，而没有比较的意味，因此作表语的形容词应用原级，应把 harder 改成 hard。 5 . “so…that…”意为“如此……以至于……”，是一个固定句型，so 修饰形容词或副词，表示程度，that 引导一个结果状语从句，应把 very 改成 so。 6 . 句中作表语的 hurt 是由过去分词演变过来的形容词，须用副词修饰，应把 bad 改成 badly。 7 . with a smile = smiling 表示“微笑着”，是固定的介词短语，应在 smile 前加 a。 8 . 按照英语习惯用法，same 作形容词修饰名词时，其前通常加定冠词 the，应把 a改成 the。 9 . fun 表示“乐趣”，“兴致”是不可数名词，应把 fun 前的 a 去掉。 10 . 表示事物的性质或特征，通常用形容词作表语，应把 easily 改成 easy。 11 . 按照英语时态的呼应规律，在条件状语从句中须用一般现在时代替一般将来时，应把 will stop 改成 stops。 12 . 先行词为表示地点的名词 lab , 关系词在定语从句中作及物动词 visited 的宾语，只能用关系代词而不能用关系副词，应把 where 改成 which 或 that。
