篇3：Unit 19 Useful expression 语言要点

一、词语例解

1. technique n 技术；技巧；手段；方法

They need to learn modern management techniques. 他们还得学习现代管理技术。

They used various techniques to get their prisoners to cooperate.他们采用了各种方法使犯人同他们合作。

【联想拓展】technicaladj.技术的；技能的 technician n.技术员；技师

【辨析】technique, technology

Technique多指具体的某方面的技术，技巧，尤指音乐、工艺美术、写作等方面。在泛指某方面的技术时是不可数名词，指具体的技巧、方法时是可数名词；technology泛指生产工艺、科学技术，含有以自然科学为基础的意思。例如：

Many people call the age we live in the age of technology.许多人把我们生活的时代叫做工业技术时代。

2. production n.1) 生产

Thousands of men were employed in the production of cars. 成千上万的人被雇来生产汽车。

That car went out of production five years ago. 那种汽车已经五年不生产了。

2) 制作；(电影)摄制；(戏剧)演出

The production of the musical comedy was a scenic triumph.该音乐喜剧的制作是戏剧上的一大成功。

Production was up last month.上个月产量上升了。

4) (艺术)作品；(研究)成果

That worthless book is the production of an ignorant author.那本没有价值的书是一个无学识的人写的。

【比较】production, product

production用作可数名词时，常用来指人类智力或艺术劳动的结果；作不可数名词时意思为“生产；产量”；product是可数名词，指任何体力或脑力劳动的产品，含义较广。

They came here in search of new markets for their products. 他们来此为他们的产品寻找新市场。

If you want to sell your product you must advertise it 如果你要推销自己的产品，你就必须做广告。

3. method n. 方法，方式

Whats the best method of cooking beef? 烧牛肉的最好方法是什么？

The new method is a good one. 这个新方法很好。

The new method works well in practice. 新方法在实践中行之有效。

【辨析】means, way, method

means着重于具体的手段，常与介词by搭配；way是指做事情的方法,也可泛指思想方法、生活方式等，常指一般的方式方法或个人的特殊方式方法，与技巧或效果的好坏无关，多与介词in搭配；method指有系统的有效率的精心拟定的方法。例如：

We must help him by all possible means. 我们必须想尽一切办法来帮助他。

I worked out this problem in this way. 我用这种方法算出了这道题。

The scientist is showing the method of scientific farming to the peasants.那位科学家正在向农民示范科学种田的方法。

Practical experience is often very important.实践经验往往是很重要的。

2) 有实际经验的；实用的

She was a simple, practical, hardworking woman. 她简朴,实际,勤奋。

3) 明智的；可行的

二、短语精析

1. depend on依靠；依赖;视……而定

It goes without saying that our plans depend on the weather. 不消说，我们的计划取决于天气如何。

Our success depends on whether everyone works hard or not. 我们的成败取决于每个人是否努力工作。

【拓展】That / It （all）depends. “这很难说；得看情况。”

I may help you，but that depends. 我也许会帮助你，但得视情况而定。

构成句型depend on/upon it that…，意为“指望……，对……不怀疑”。如：

You may depend on it that she will help you. 你可以相信她会帮助你的。

You may depend on it that he will join our club.=You may depend on him to join our club. 你可以不用怀疑他会加入我们俱乐部。

2. bring in引进；带进来；赚钱

New ideas have been brought in since China was opened to the outside world. 中国自从对外开放以来，引进了很多新的思想。 The sale of his new record brought in 1 million dollars. 销售他的新唱片赚了一百万美金。

The game is going against the visiting team. 这场比赛对客队不利。

4. year by year 年年；逐年

I grow taller year by year. 我一年年长高。

Year by year their affection for each other grew stronger. 他们彼此的爱慕之情逐年加深。

【辨析】year by year表示每年都有所变化；year after year表示每年一成不变。例如：The flowers remain the same year after year while people change year by year. 年年岁岁花相似，岁岁年年人不同。

5. make（good）use of sth （充分）利用某物

He made good use of his time there by learning the language. 他充分利用他在那儿的时间来学习语言。

【拓展】in use 在使用中out of use不再使用 be of use 有用的make the most of 充分使用某物 take advantage of利用

三、句式点睛

1. To make as much use of the land as possible, two or more crops are planted each year where possible. 为了尽量利用土地，人们每年在可能的地方种植两种或更多的农作物。

To make as much use of the land as possible是动词不定式短语作状语，表示目的。例如：We went to the hospital to see our teacher.我们去医院看了我们的老师。

She stood up to be seen better.她站起来以便让人更好地看见她。

注：如果不定式的逻辑主语与句子的主语不同，则需要用 for 将不定式的逻辑主语引出，置于不定式之前。例如：

The hostess opened the door for the guests to come in.女主人打开门让客人进来。 动词不定式作目的状语也可用 in order to, so as to等来代替。又如： He opened the window in order to let the fresh air in.他把窗户打开，以便让新鲜空气吹进来。

He left early so as not to miss the first bus. 他走得很早以便不错过早班车。

课本里这个句子的动词不定式做状语，但其逻辑主语却不是句子的主语，拘泥于传统语法的人也许认为用得不对。但本编辑部认为是对的。《综合英语语法》的作者埃克斯利父子说得对，语法只是语言学家们根据他们所见到的语言现象所概括起来的规则，但语言是活的，不断变化发展，如果一旦用法跟规则不一致，那么错的是规则，应予修订。现在夸克等人认为，如果动词不定式或分词的逻辑主语是泛指或从上下文可以知道其逻辑主语是谁时，作状语，其逻辑主语可以跟句子主语不一致。此处的不定式逻辑主语是泛指。

where possible是被省略主语和系动词的状语从句，完整的形式是where it is possible。当时间、条件、方式和地点状语从句的主语和主句的主语一致或者是it时，如果谓语部分有动词be，就可以将从句的主语和be动词省略。例如：

Dont speak until（you are）spoken to. 有人对你说话时，你才开口。

Once（it is）seen, it can never be forgotten. 一旦看见它，便会终生难忘。

If（it is）necessary, we shall send a telegram home. 如果有必要，我们就往家里打电报。

Come to see me at once, whenever（it is）possible. 一有可能，就立即来见我。

2. Some of the land in China is too wet to grow crops. 在中国因为有些土地太湿，不能种庄稼。

“too＋adj. / adv. + to do sth.”结构表示否定意义，意为“太……而不能”。例如：

You are too young to understand such things.你太年轻不懂这些事情。

The problem is too difficult for me to work out.这道题太难我解不出来。

注意在下列情况中too… to…表示肯定意义：

（1）某些形容词与too…to…连用表示肯定意义，此结构中，too相当于very或very much；这些形容词主要是表示情绪的词，如ready, glad, pleased, surprised, delighted, happy, easy, thankful, anxious, willing等，也有描述性形容词，如：good, kind, true等。例如：They were too anxious to leave.(=very anxious to leave)他们急于要离开。

He is too glad to go there. (=very glad to go there)他非常高兴去那儿。

（2）too前加上only, but, all, simply或just时，too…to…表示肯定意义，此时，too带有感情色彩。例如：

He is only too pleased to have received her invitation. 他收到她的请柬非常高兴。

She is but too willing to help others.她非常愿意帮助别人。

（3）too…to…和never, not连用时，表示肯定意义，意为“非常”、“不会不”；not位置不同，所修饰的词也不同。例如：

She is too careful not to have noticed it.她那么细心，不会不注意这一点的。

One is never too old to learn.人绝不会因年纪太大而不能学习。/ 活到老,学到老。

3. The roots of these vegetables are not planted in earth but hang in water that contains all the nutrients they need to grow. 这些蔬菜的根不是种植在地里，而是挂在含有它们生长所需要营养的水中。

not…but…意为“不是……而是……”，连接两个并列成分，后面可跟名词、形容词、副词、短语、从句等。例如：

My bag is not black but red.我的书包不是黑的而是红的。

The letter is addressed not to me but to you.这封信不是写给我的而是写给你的。

He failed not because he isnt clever but because he didnt work hard.他失败了不是因为他不聪明而是因为他没努力。

not…but…连接两个名词在句中作主语时，强调后者，谓语动词与but后的名词保持一致。例如：

Not I but Tom and Mary are fond of watching TV. 不是我而是汤姆和玛丽喜欢看电视。

四、语法细解

It用法（II）

“It is + 被强调部分+ that…”是强调句型。将被强调的部分放在It is之后,句子剩余的部分放在that之后。被强调部分常为句子的主语、宾语、时间状语、地点状语、方式状语和原因状语，也可为主语从句、宾语从句、时间状语从句、原因状语从句或not only…but also…，either…or…，neither…nor…,…as well as…，not until等复杂结构；is指现在或未来的情况，was指过去的情况；被强调部分为人用who/that做强调词，被强调部分为物用that做强调词，被强调部分为人称代词时原句用什么格，强调句也用什么格，如果被强调部分为主格人称代词，who/that后面的动词应和它在人称和数上保持一致。如果把It is … that去掉后，剩余的部份应该是一个结构完整，意思明确的句子。这也是强调句型与其它从句的区分方法。试对比下列两组句子：

1. It was last year _______I joined the Party.

A. When B. in which

C. thatD. at that time

析：把It was和空白处去掉后，剩下Last year I joined the Party，作为句子可以成立，属于强调句型，故选C。

2. It is the year _______he joined the army.

A. whenB. that C. whichD. at that time

析：把It is和空白处去掉后，剩下The year he joined the army,意思不明确，所以不是强调句，应考虑定语从句，选A。

此外“It is not until + 被强调的部分 + that …”也是强调句型。主要用于强调until 引导的时间状语，译成汉语“直到……才……．”，可以说是not…until…的强调形式。

I didnt realize she was a famous film star until she took off her dark glasses.

It was not until she took off her dark glasses that I realized she was a famous film star.

注意It以下的常见句型：

1. It is said (reported, learned…) that…

该句型中的it仍是形式主语，真正主语是that引导的主语从句。该结构常译为“据说（据报道，据悉．．．）”。

2. It is time (high time) that…

该句型中that后的从句应该用虚拟语气，常用过去时态或should+原形动词（should不能省略）。

3. It is the first (second…) time that…

该句型中的that从句用完成时态。如果主句的谓语动词是一般现在时，后面从句用现在完成时态；如果主句的谓语动词是一般过去时，后面从句则用过去完成时态。

4. It is …when…

该句型中的when引导的是一个时间状语从句，主句中的it指时间，表语由具体的时间充当。常译为“当……的时候，是……”。

5. It be…before…

该句型主句中的it指时间，主句中的时态常是一般将来时或过去时两种时态，主句中的表语多是long, not long, 3 days, 2 weeks等表示时间段的词或短语。常译为“……之后才……”或“不久就……”。

6. It is no good (use) doing sth.

该句型中的真正主语是动名词短语，主句中的表语可以是no good, (not any good), no use, (not any use)。

It is no good learning English without speaking English.

7. It doesnt matter whether (if) …

该句型中whether (if) 引导的从句是真正主语，该句型常译为“不论（是否）……没关系”。

【典型考例】

1. It was only with the help of the local guide ______. （2004上海春）

A. was the mountain climber rescued

B. that the mountain climber was rescued

C. when the mountain climber was rescuedD. then the mountain climber was rescued

解析：B。该句为强调句型，被强调部分为方式状语only with the help of the local guide，因此应选B。

2. It was not until she got home _______ Jennifer realized she had lost her keys.（2006全国卷II）

A. when B. that

C. whereD. before

解析：B。该句为强调句型，被强调部分为not until…结构，因此该空应填that。

3. It was after he got what he had desired _______he realized it was not so important.（2006辽宁卷）

A. thatB. whenC. sinceD .as
