内容
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
Ⅱ . 交际英语
打电话
1 . Can you ring up … ? 2 . I can't get through .
3 . The line's busy . 4 . I'll try again later .

7 . Can I take a message ? 8 . This is … speaking .
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 .
— Will it rain ?
— No , I suppose not . ／I don't 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 ?
电话中的“请等一下”
高一下册第25单元和第26单元出现打电话时说的“请等一下”的句子，其英语表达形式丰富多彩：
1 . A minute , please . 2 . Just a minute .
3 . Just a moment . 4 . One moment , please .
5 . Hang on a moment , please . 6 . Hang on a minute , please .
7 . Don't hang up , please . 8 . Hold on , please .
9 . Hold on a second , please . 10 . Hold the line , please .
11 . Would you hold the line a moment ? 12 . Would you wait a minute ?

3 . attention 注意，关心

16 . go over to —— 走到 ( 某人或某物 ) 去
Dr Baker got up and went over to the organizer .

〖 点拨 〗go over to 与 go over 的意思不一样。go over 是“重复，重温，仔细检查”等意思。如：
Let's go over the lesson again .
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 .
【妙文赏析】
Swimming 游泳
When all the days are hot and long 每当白昼炎热、漫长
And robin bird has ceased his song , 知更鸟停止了歌唱，

And have the finest kind of play . 那是最美好的消遣。
I've learned to dive and I can float , 我学会了潜水和浮游

For I can see the ducks go by . 因为我见身边的鸭群还在畅游

If I could only be duck . 那我该多么幸福 !
〖 赏析 〗《游泳》是一首十四行诗，文字浅显如儿歌，脍灸人口。炎热的夏季，在河里嬉戏玩耍，自由自在，非常惬意。孩童的天真浪漫，活泼好动，在诗中通过 dive , float , sp
lash , plunge , laugh , shout 等几个词语表现得淋漓尽致。阳光，孩童，小溪，白鸭，欢声笑语，恬淡清新，构成一副令人爽心悦目的戏水图。

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”。

单句改错

2 . I was preparing dinner while you called me .
3 . He was used to be as strong as a horse when he was in the countryside .
4 . It's harder for women to get to the top of a company .

11 . I don't want to be friends with him unless he will stop telling lies .
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。
