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

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 .

5 . could i speak to …, please ? 6 . hold on , please .

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 ?

二、学海荡舟

【学法指要】

单元重点词汇点拨

2 . funny 有趣的，滑稽可笑的

i don\'t think that\'s at all funny .

what fun it is to see a film !

3 . attention 注意，关心

pay attention to what you are doing .

we have given close attention to these needs .

they listened with great attention .

〖 点拨 〗词组：pay (much , no , little , more …) attention to注意…… 。fix one’s attention on精力集中中……。with attention = attentively聚精会神地。

4 . unable 不能的，不能胜任的

he seemed unable to understand what you said .

i am sorry to be unable to come .

〖 点拨 〗将来时和完成时一般不用 unable , 而用 not able . 另外，注意unable在句中时的反意疑问句：he is unable to help us , isn’t he ?

12 . as a guide —— 作为指南，作为向导

16 . go over to —— 走到 ( 某人或某物 ) 去

dr baker got up and went over to the organizer .

he went over to the other side of the street .

we went over to the next town to the game .

〖 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 .

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。

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“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 .

10 . english lessons on tv with explanations in chinese are easily to follow .

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。
