【难点解析】

Ⅰ.Hot words and hot phrases常用词与常用词组

1.It takes a very unusual mind to undertake the analysis of the obvious.(P.l)

译文:分析明显存在的事情需要非凡的头脑。

[讲解]undertake(undertook;undertaken)有两个意思。①to take up or start on(or a piece of work esp. one that is difficult or need effect)担任(职位);着手(艰苦工作等)。后常用名词、代词作其宾语。②to promise or agree答应;同意。后加不定式或that从句作宾语。

[例句]

She undertook responsibility for the accident.

她承担了这次事故的责任。

He undertook to pay back the money within 2 months./He undertook that he would pay back the money within 2 months.他答应两个月之内还钱。

He undertook to be here by 10 o'clock./He undertook that he would be here by 10 o'clock...他答应10点前到达。

[讲解]本句中出现的另一个词obvious为形容词,意为“显而易见的;明显的”。obviously adv.显而易见地,这类形容词如用定冠词,表示一类事物或人,又如:the rich富人,the disabled残疾人。

[例句]

It is obvious that mastering the English language is a must in international trade.很显然,在国际贸易中,掌握英语是必要的。

He is obviously mad.=It is obvious that he is mad.很显然他疯了。

2.Each group member represents a branch of science.(P.2)

译文:每组成员代表着一个科学分支。

[讲解]represent vt.意为“代表”,作此义讲时,它的同义词是“stand for”,但stand for不可用于被动语态。

[例句]

She represented president in the conference.在会议上她代表总统。

In Chemistry,O represents Oxygen.在化学中O代表氧元素。

The rose represents England.玫瑰花是英国的象征。

Our company is represented in China by Mr.Smith.

[讲解]branch名词,原意为“树枝”,引申义为“(河流的)支流;(铁路的)支线;(家族的)分支;(公司的)分店、分公司;(组织的)支部”等。

[例句和例词]

3.Scan the text to answer the following questions.(P.3)

译文:浏览课文,回答下列问题。

[讲解]scan(scanned;scanned) vt.-glance at(e.g. a document)quickly but not very thoroughly匆匆而粗略地看(文件等);略读。

[例句]

She scanned the list of names to see if hers was on it.

她扫了一下名单,看自己的名字是否在上面。

4.Imagine this:you are twenty-one years old and a promising graduate student at one of the top universities in the world.(P.3)

译文:想象一下:你21岁,是世界一所顶尖大学的一名很有希望的大学毕业生。

[讲解]promising形容词意为“大有希望的;有出息的;有前途的”。该词是promise的同源词。promise作动词或名词时,除了我们较熟悉的“允诺”“诺言”,还有其他意思。作动词时,promise还有“预示”的意思。作名词时还有“(有)指望;(有)前途”的意思。

[例句]

All of you are promising if you learn English well.

如果你们学好英语,你们非常有前途。

The results of the first experiment are very promising.

第一次试验结果充满了希望。

It's a promising sign.那是一个很好的迹象。

It promises to be warm this afternoon.今天下午有望变暖。

The clear sky promises fine weather.晴朗的天空预示着好天气。

[讲解]①graduate在此句中为名词,意为“毕业生”。当你步入大学校门,一年级时,你被称为freshman;大二时,被称为sophomore;大三时,被称为junior;大四时,被称为senior;当你已基本完成学业,但尚未取得学士学位时,被称为undergraduate;拿到学士学位后,又继续上硕士或博士,那你就被称为postgraduate,graduate作名词时有时也可指硕士或博士研究生。②graduate作动词时,意为“毕业”,后加介词from/at+学校;加介词in+专业;加介词with+学位。

[例句和例词]

a graduate nurse一名护士学校毕业的学生

a graduate student一名研究生

He graduated in law at Oxford.他毕业于牛津大学法学专业。

He graduated from Beijing University with a Doctor's degree in history.

他毕业于北京大学,获得史学博士学位。

5.Yet two years had gone by and I was not that much worse.(P.3)

译文:然而两年过去了,我的情况却不是那样糟糕。

[讲解]go by有三个词义。①to pass(in place or time)(时光)流逝;经过(某处)。②be guided by依照;遵循,依据……办事。③to judge by根据……作出判断。作上面②、③词义讲时不用被动语态。

[例句]

A car went by.一辆汽车驶过。

As time goes by/passes,all of you have grown into big boys or big girls.=With time going by/passing,all of you have grown into big boys or big girls.随着时光的流逝,你们都长成大小伙子,大姑娘了。

6.In fact,things were going rather well for me and I had gotten engaged to a very nice girl,Jane Wilde.(P.3)

译文:事实上,事情发展得还挺顺利,我和一位非常好的女孩简怀尔德订了婚。

[讲解]get engaged to sb.意为“与某人订婚”,注意:①get为瞬间动词,意为“变成”,所以get engaged to sb.不可与表一段时间的时间状语连用。表一段时间时,可用be engaged to sb.get/be married to“与某人结婚”也是如此。②牢记本短语的介词to,不要受汉语影响,误记为with。

[例句]

Tom got engaged to Mary 3 weeks ago.汤姆和玛丽三周前订了婚。

Tom has been engaged to Mary for 3 weeks.

It is 3 weeks since Tom got engaged to Mary.

汤姆和玛丽订婚三周了。

7.Since then,Hawking has continued to seek answers to questions about the nature of the universe.(P.3)

译文:自从那时,霍金就一直探求关于宇宙本质问题的答案。

[讲解]seek(sought,sought,seeking)。seek to do sth(=attempt to do sth.=try to do sth.=do as much as sb.can to do sth.=do as much as possible to do sth.=do what sb.can to do sth.=make an effort to sth.=spare no effort to do sth.)设法(试图)做某事;seek sth.寻找、征求、谋求、追求;seek after追求、企图得到;seek for寻求/寻找;seek one's fortune外出找出路。

8.Scientists...know that their job is never finished and that even the best theory can turn out to be wrong.(P.4)

译文:科学家们……知道他们的工作永远不会结束,甚至认为即使最好的理论也可能被证实是错误的。

[讲解]turn out有三个意思:①produce生产,培养;②prove被证实;③to come out or gather(as if)for a meeting,public events etc.群体出动。作“被证实”讲常用“...turn out(to be)+adj./noun”或“It turn out that从句”两种句型。

[例句]

译文:听过霍金报告的人有时发现理解他的报告太难了,……

[讲解]it除作代词外,还可用作引词(anticipatory)。引词本身无实义,只起一种先行引导的作用。引词it不重读,它可用作形式主语、形式宾语;还可用于强调句型。现在让我们学习一下it作形式宾语的用法。

1)真正宾语是不定式

e.g. I find it easy enough to get on with Pam.

(it指代to get on with Pam)我觉得与Pam相处很容易。

I'd think it useful to learn computers.

(it指代to learn computers)我认为学电脑有用。

2)真正宾语是动名词

e.g. You must find it exciting working here.

(it指代working here)你一定发现在此工作令人激动。

I think it no use advising him to give up his plan.(it指代advising him to give up his plan)我认为建议他放弃计划没用。

3)真正宾语是宾语从句

I took it for granted that you would stay with us.(it指代that you would stay with us)我以为你当然会留在我们这里的。

译文:每个人都有自己的专长和兴趣,只有发现自己的专长,我们才能期望达到自己的目标,真正与众不同。

[讲解]当only引导状语处于句首时,主句要用倒装的语序。注意:1)当only引导非状语处于句首时,主句不必用倒装的语序;2)当only引导状语处于句中或句末时,主句也不用倒装的语序;3)当only引导状语从句处于句首时,要倒装主句的语序,千万不要倒装从句的语序,而忘了倒装主句!

[例句]

Only in this way can we learn English well.

只有用这种方法我们才能学好英语。

Only when the war was over was he able to get happily back to work.

只有在战争结束后,他才高高兴兴地返回工作。

B.Grammar focus语法重点

1.The simple passive form of the infinitives.

不定式被动态的一般形式的内涵及用法。

2.Four functions of the infinitives used as subject,attribute,object and adverbial.用作主语、定语、宾语和状语的不定式的四种功能的用法。

本单元的语法项目是不定式的被动式,具体讲解如下:

①当不定式的逻辑主语是不定式所表示动作的承受者时,不定式一般用被动形式。不定式被动形式在句中可作主语、表语、状语、补语等。如:

To be obeyed was natural to her.她生性让别人听命于她。(作主语)

The problem remained to be solved.这个问题还有待解决。(作表语)

It needs not to be said that they are very happy together.

不必说他们在一起非常幸福。(作宾语)

There were plans to be made at once.要立即制定计划。(作定语)

He has returned only to be sent away again.

他回来以后又被打发走了。(作状语)

The captain ordered the flag to be hoisted.

船长命令升旗。(作宾语补足语)

The book is intended to be read and not to be torn.

这书是供人阅读的而不是供人撕毁的。(作主语补足语)

②在某些句子中,不定式虽表被动,但仍用主动形式。如:

What is to pay?要付多少钱?

The reason is not far to seek.道理很浅显。

He gave me some books to read.他给了我一些书读。

We found the report easy to understand.我们发现这些报告很容易懂。

不定式作主语、定语、宾语和状语的功能和用法讲解如下:

由于不定式有名词、形容词和副词的特点,所以它在句中可做主语、表语、宾语、定语、同位语、状语、补语等。但由于时间关系,今天我只把不定式作主语、定语、宾语和状语的用法讲解一下。

1)作主语。如:

To see is to believe.眼见为实。

To serve the people is our duty.为人民服务是我们的职责。

在日常英语中,常用it作为语法上的主语,即形式主语,而将真正的主语放在后面。

It is our duty to serve the people.为人民服务是我们的职责。

2)作宾语。如:

I couldn't afford to buy a new car.我买不起汽车。

Have you decided to marry him?你决定嫁给他吗?

有些动词常常跟不定式作宾语,它们是:want,wish,hate,prefer,hope,continue,manage,try,ask,offer,start,forget,remember,begin,decide,agree,choose,learn,pretend,promise,mean,expect,desire等。

另外,在一些复合宾语中,常用it代表不定式作为形式宾语,而将真正的宾语不定式放在后面。如:

I thought it right to do this test.我认为做这项实验是对的。

3)作定语。通常都置于被修饰名词或代词之后。如:

This is the best way to solve this problem.

这是解决这个问题的最好办法。

I have a lot of work to do.我有许多工作要做。

如果不定式和它所修饰的词有逻辑上的动宾关系,且这个不定式是不及物动词,则它后面需有必要的介词。如:

He is a good comrade to work with.他是一个很好共事的同志。

There is nothing to think about.没什么值得考虑的。

4)作状语,表示目的、结果、原因等。如:

He went home to see his parents.他回家看望父母。(表目的)

I turned the radio down so as not to disturb you.

我把收音机音量调小,以免打扰你。(表目的)

The problem is too hard to understand.

这问题太难了,理解不了。(表结果)

What have I done to make you unhappy?

我做了什么事使你不高兴?(表结果)

I'm glad to hear the news.听了这消息,我很高兴。(表原因)

I was surprised to see him there.

我真想不到会在那里见到他。(表原因)

Ⅲ.Skills of the four essential abilities:listening,speaking,reading and writing听、说、读、写四项基本能力的学习技巧

1.Listening skills听力技巧

Have a good understanding of a long dialogue by grasping the reason why an event happens.

掌握某事发生的原因,很好理解一段较长对话

在高二的第一学期我们主要学习如何听好较长对话的一系列技巧。

较长对话与简短对话的检测有哪些区别?

简短对话在篇幅上,比起较长对话要短;简短对话只有一个检测点,因此只有一个设问,而较长对话有若干个检测点,因此有若干个设问。简短对话侧重于句子层次理解的考查,而较长对话侧重于话语或语段层次的检测。一般说来,如果一段较长对话有两个设问,那么这段对话涉及的内容至少是两个,所以在审题中,应把在应对简短对话中的那些技巧使用起来,而且还应学会通过审题中得到的信息来把握各个设问之间的内在联系,从而推断出还未听到的较长对话的大致内容,进而确定听音的重点的技巧。听其对话录音时,要尽力把握能正确解决设问的关键词、短语或句子。

以高考试题的实例讲解本节的中心议题。

请看下例(2002年高考试题,全国卷):

1.why does the man thank the woman?

A.She has helped him with his problems.

B.She has invited him for coffee.

C.She has agreed to see him on Monday.

2.When does the conversation take place?

A.Before class. B.After class. C.During class.

首先你们应仔细审读这两个设问及其选项。看看从审题中能得到哪些信息?

第一个设问是:为什么这位男士要感谢这位女士?这段较长对话的第二个设问是:这段对话发生在什么时间?这两个设问有什么内在联系呢?

孤立地看这两个设问及选项,似乎看不出它们的内在联系,但如果你是个细心的有经验的应试者,应该能确定此段较长对话发生在学校,因为第二题的选项提供的时间,都是发生在学校里的时间现象:A.上课前;B.下课后;C.课程进行的过程中。根据生活常识,我们可以推断出对话的双方最大的可能都是学校中的人士。那么其对话内容很可能与学校生活有关。再有从审读第一个设问的选项的内容,我们得知男士感谢女士的原因有以下三个:A.女士帮助他解决了一些问题;B.女士邀请他喝咖啡;C.女士同意在星期一会见他。带着这些问题我们再听对话录音,就是有备而听。这时我们听到如下这段较长对话的录音:

M:Thank you very much,Miss Times.That helped me a lot.

W:I'm glad I could be of some help,Carolos.Let me know if you still have any more questions later.

M:I will.And thank you for giving up your coffee break to help.I know you need one after teaching three classes.

W:Oh,I don't mind.Teaching is what I love most.

M:Well.Good bye and thanks again.

W:You're very welcome,Carolos.See you in class next Monday.

听完这段较长对话两遍之后,我深刻体会到从正确审题中所获取的信息,进而做到有备而听是解答这类较长对话听力题的基础与前提。在听对话录音时,把握其中的关键词、短语或句子是正确做出判断的关键。我在录音中听到该男士三次向女士致谢,在他第二次致谢时,他解释了他致谢的原因:感谢女士放弃了在教了三节课后喝咖啡的休息给他讲解问题,同时又听到女士乐于给他讲解问题的陈述,由此得出上面两个设问的正确答案应该是稳操胜券的事。

2.Oral practice口语训练

Talk about science and scientists

谈论科学与科学家

我们怎样才能较好地用英语谈论科学与科学家呢?

就科学而言,主要两大类:社会科学与自然科学。

本教学单元一共提及七位科学家:哥德、爱因斯坦、居里夫人、爱迪生、霍金、伽利略与培根。在他们中间哥德与培根属于社会科学家,其余的五位都是自然科学家。

自然科学有很多分支,例如:数学(mathematics or maths),物理学(physics),化学(chemistry),生物学(biology),天文学(astronomy)与计算机学(computer science)等。

知道这些自然科学的英语表达方式后,我们应如何谈论这些科学及其科学家呢?

要谈论这些科学,首先应掌握这些科学的英语表达方式,然后发表自己认为哪门科学最重要(the most important),最有兴趣(the most interesting)和最有用(the most useful),然后讲清你为什么认为它最重要、最有兴趣和最有用。

要谈论这些学科的专家,首先应掌握他们各自的英语表达方式:

数学家mathematician 物理学家physicist

化学家chemist 生物学家biologist

计算机专家或科学家computer expert/scientist

假定你认为数学是一门最重要、有兴趣和有用的科学,你将如何表述你的见解及你这种看法的理由呢?

我将用如下方式表示我的看法及其理由:

I think mathematics is the most important,interesting and useful science,firstly because it's the basis of each branch of other sciences;secondly because it is closely connected with our daily life;thirdly because one can become cleverer and more rigorous(严谨的)through studying the science of maths...

要谈论一位科学家,就应对他的身世与他在他的研究领域的建树和功绩有所了解。因此以下这些句式都常用来谈论科学家,请看:

1.What is the name of the man who wrote the best-seller“A Brief History of Time”?

2.What is his greatest contribution to modern science?

3.When and where was he born?

4.Where did he grow up?

5.Where did he receive his advanced education?

6.When did he get his PhD degree?

7.When did he become well-known all over the world?

8.What famous theories of his is usually expressed in his speeches?

9.When did he visit China?

10.What does he think of science and scientists?

很明显这些问题针对本教学单元中NO BOUNDARIES这篇课文设问的,根据课文中对史蒂芬霍金的介绍的内容给予回答就是对科学家及他研究的理论谈论很好的例证。

3.Reading skills阅读技巧

How to grasp the core of a very long sentence

如何抓住一个长句的核心

在我们现在的阅读中,虽然在文章或句子中没有生词,但我们仍然对短文或句子,尤其是那些长句往往不能很好的理解,这究竟是怎么一回事?

这是你们现在所处的学习阶段里出现的一个通病。

阅读较难的读物时,常遇到很长的句子。这些长句往往对初学者来说是很难正确理解的。如果能抓住句子的核心(the core of a sentence),困难就会迎刃而解。

1.找出句子的核心

所谓句子的核心,就是指句子最主要的部分,即主语、谓语动词及其宾语或表语。它们是句子最基本的成分。一般地说,长句的核心不过是几个关键词,其他部分都为这几个关键词服务,或是描述修饰它们,或是解释说明那些细节,如原因(why),方式(how),时间(when),地点(where),何物(what)及结果(what result)。下面我们以1995-1998年高考考题里阅读理解文章的一些句子为例,说明如何找出这些句子中的核心。

Twenty students had just climbed their way to the top rung(最高的台阶)out of 4 million students taking part in the Fifth National Hua Luogeng Gold Cup Mathematics Contest on Tuesday evening at Jintan,Jiangsu Province.

句子的核心:students...climbed

句子的细节:How many:twenty out of 4 million

现在分词短语taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe。置于此种位置的分词短语起的是解释说明的作用,回答的是:What kind of work does the“dustman”do?如果再细致进行下去,还可对这个分词短语各个成分作分析。这样,全句的意思就清楚了。

2.找出核心词的过程中应注意的三个常见的语言现象

(1)注意倒装句:英语中有时为了保持句子的平衡,或为了取得特别效果,要把谓语动词放在主语前面形成倒装句。例如:

①In the far distance was seen the glittering(闪光的)surface of a lake surrounded by large and tall willow trees.

先找出动词:was seen

用what放在动词前发问what was seen...,找出其主语:surface of a lake,核心词:surface of a lake was seen经过语法分析明确动词was seen之前的介词短语In the far distance为地点状语,而主语surface of a lake之后的过去分词短语surrounded by large and tall willow trees是作修饰lake的定语。这样,准确理解此句就应是理所当然的结果。

②With the last hours of the afternoon went her hopes,her courage and her strength.先找出动词:went

再用what放在动词前提问:what went?找出其主语hopes,courage,strength,其核心词:hopes,courage,strength went

最后作语法分析,得出结论:with the last hours of the afternoon是句子的时间状语,意为:就在那天下午的最后几个小时里,……

(2)注意主从复合句:“剥卷心菜”法是处理主从复合句的有效方法。

在实际的阅读中,会经常遇到主从复合句。在处理主从复合句时,应首先处理主句,然后再解决从句。主句应视为“菜心”,从句则是包在“菜心”外的“菜叶”。处理它们的程序仍是抓住核心及语法分析等方法。下面以高考英语试题的阅读文章中的句子为例,做些实际分析。

①In the 19th century when English ladies went swimming in the sea,they hired a bathing machine,which was used for changing in,and for taking the bathers down to the sea.(1996)(本句为带有2个定语从句的主从复合句。)

主句:they hired a bathing machine

时间状语:in the 19th century...(其后的when English ladies went swimming in the sea为修饰century的定语从句)

定语从句:which was used for changing in,and for taking the bathers down to the sea用来说明machine的。

然后再按上述方法找出主句及从句的核心,最后再对主句及从句的细节做语法分析。用这种方法理解(这样的)较长的难句是很有效的方法。

②Carmakers' research and development laboratories have already proved that mixing in more noise with the help of loudspeakers can reduce the unwanted noise.(1995)

主句:Carmakers' research and development laboratories have already proved...

宾语从句:that mixing in more noise with the help of loudspeakers can reduce the unwanted noise.

主句的主语的定语:carmakers' research and development

宾语从句的宾语:the unwanted noise

(3)注意并列句:“切割”法是处理并列句的有效方法。

并列句或并列复合句也是阅读文章中常见的情况,合理地将它们分而解决之是行之有效的。例如:

The idea of fighting a noise by making more noise sounds strange,but that's exactly what motor engineers are doing in Germany and some other countries.(1995)

这是一个并列复合句,由并列连词but连接两个并列子句。第二个并列子句中有一个表语从句。

第一个并列子句的核心

谓语:sounds strange(系动词+表语)

主语:the idea...

第一个并列子句的细节

修饰主语的定语:...of fighting a noise by making more noise

第二个并列子句的核心

谓语:is what...countries(系动词+表语从句)

主语:that

表语从句的核心

谓语:are doing

主语:motor engineers

表语从句的细节

谓语动词的宾语:what

地点状语:in Germany and some other countries

4.Writing capacities书面表达能力

How to write a descriptive paragraph

如何写一个描述性的段落

怎样写好一篇描述性的短文呢?

本单元学习的是对科学家的介绍,我们应学以致用,写关于介绍科学家的描述性短文。与学习汉语写作一样,首先应确定我们要写的内容,然后根据要写的内容来确定写作的方式。

在介绍一位科学家前,你应该考虑清楚你要写的科学家是哪一位?你为什么最喜欢他/她?他/她生活中有哪些重要和有趣的事?读者需要对他/她了解些什么?考虑好这些问题,就应解决写作方式的问题。

描写文是用生动语言描绘人、事、物、场景或过程,使人物有血有肉,活灵活现,把事情的过程、发生的场景变得具体、形象与生动。描写文与记述文的不同之处在于是对人或事物作概括和交代,而描写文则是具体的描述与刻画。

描述科学家的特征的形容词与名词

curious adj.求知欲强的 careful adj.细心的

patient adj.有耐心的 creativity n.创造力

imagination n.想像力 perseverance n.毅力

discovery n.发现 invention 发明

theory n.理论 success n.成功

因为有成就的科学家都是求知欲旺盛的,细心的与有耐力的,他们都有丰富的想像力,坚忍不拔的毅力与了不起的创造力,他们或是有伟大的发现与发明,他们的理论往往在开始时不被世人理解,或使人大感惊愕。所以他们的人生往往是以伟大的成功划上圆满的句号。

所以你可以上网查寻你认为最了不起的科学家的各方面情况,上面讲述的思路,写作特点与描述科学家的词汇应该对你的写作有所帮助。

由于在“难点掌握”中已经讲解过描写科学家的短文的写作方法和注意事项,现将示范短文展示如下:

Madame Curie-a Great Woman Scientist Marie Curie was born in Poland,on Nov.7th,1867.As a child,she was very curious to learn anything new to her.She was interested in the science of physics and read as many books as she could find on the subject.At that time women were not allowed to study at universities in Poland,so Marie was determined to go to France and study there.She arrived in Paris in l891.Though she was very poor,she studied very hard with such great perseverance that she managed to take a first-class degree in physics two years after arriving in Paris.Soon after her graduation Marie married Pierre Curie,a very eminent scientist who was teaching at the school of physics and Industrial Chemistry at Paris.They both began to do research on the phenomenon of radioactivity which another scientist named Becquerel discovered.As they had great patience and were very careful,they discovered two kinds of radioactive elements:polonium and radium.Unfortunately,Mr Curie was killed in an accident in 1906.After that she went on with the research though she suffered a lot from the loss of her husband.As a result of her research,she greatly promoted the development of science nuclear.In 1903 a Nobel Prize for physics was given to the Curies and the scientist named Becquerel,and in 1911,Madame Curie won a Nobel Prize for Chemistry for a second time,and she will always be remembered as a great woman scientist.
