because of, due to, owing to, on account of和thanks to的用法比较:这一组词都表示"由于"的意思，在使用时应该注意以下区别： 1.because of意为"由于，因为"，强调因果关系，在句中仅作状语，修饰句中的一部分，与其他成分不用逗号隔开。如：We must not get discouraged because of such a minor setback.我们决不可因为这样一个小小的挫折而灰心丧气。 2.owing to与because of一样，也强调因果关系，除作状语外，也可作表语。作状语时修饰整个句子，可在句首或句末，用逗号隔开。如：They decided to cancel the flight，owing to the storm.由于这场暴风雨，他们决定取消这个航班。 His death was owing to an accident.他死于一场事故。 3.due to引出造成后果的原因，在句中作表语、状语和定语。作表语和状语时与owing to同义，作状语时，一般不与其他成分隔开。如：This accident was due to(owing to)his careless driving.这次车祸是由于他开车疏忽大意造成的。 He arrived late due to(owing to)the storm.由于暴风雨他来晚了。 Mistakes due to carelessness may have serious consequences.由于疏忽大意造成的错误可能带来严重的后果。 4.on account of与because of，owing to同义，但语气较为正式。可作状语、表语，不作定语。如：He could not come on account of his illness.他因病不能前来。 That was on account of lack of exercise.那是由于缺乏锻炼。 5.thanks to表示"幸亏，多亏"多用于表达正面意思，相当于感谢，在句中作状语和表语。 Thanks to your advice，much trouble was saved.

C. after all                    D. at all解析： ①选D。由语境逻辑可以推出该空表示“另外，除此之外”，只有D项与句意相符。 ②选B。考查“介词+all”的短语辨析。句意为：我想买一座房子——时尚、舒适，最重要的是社区要安静。in all 总共;above all 最重要的是;after all 毕竟;at all根本。   13. deal with处理;安排;对付

辨析 do with/deal with表示“怎样处理”时，do with常与连接代词what连用，而deal with常与连接副词how连用。这两个短语在意思上有细微的差别。一般来说，do with意为“处置;忍受;相处;有关”等。 deal with意义很广，意为“对付;应付;处理;安排;论述;涉及;与……打交道/做生意”等。

How are you going to deal with the problem? 你们打算怎样处理这个问题呢? Such man is difficult to deal with. 这种人不容易相处。 I’ve dealt with him for ten years.我和他做生意已经10年了。 This book deals with the Middle East.这本书是关于中东问题的。 He didn’t know what to do with the property his father had left. 他不知道如何处理他父亲留下的财产。 I can’t do with the loud noise. 我无法忍受那种噪音。

14. watch over看守;监视;照看

Could you watch (over) my clothes while I have a swim?我游泳时你能帮我看着我的衣服吗? He felt that God was watching over him.他感觉到上帝保佑着他。

watch out (for)当心，注意 watch for sb./sth.观察;等待 keep a watch on监视 under the close watch在严密监视下

翻译句子 ①他们等待着进一步的发展。 ②小心!汽车来了。答案：  ①They are watching for further developments. ②Watch out! There’s a car coming.

重点句型

15. ①so ...that ...意为 “如此……以至于……”。     ②such+    a/an+adj.+单数可数名词+that-clause                       adj.+复数名词+that-clause                       adj. +不可数名词+that-clause

提示 so that既可以表达结果，又可以表达目的，表目的时相当于in order that。 I stopped so that you could catch up.我停下来以便你能赶得上。 “so ...that ...”结构中的“so+adj./adv.”位于句首时，主句要倒装。 So hard does he work that he seldom goes home.他工作那么努力，几乎不回家。 “such ...as ...”中的as引导的是一个定语从句。

单项填空 —What a beautiful day! —Yes, it’s             that I’d like to take a walk. A. such nice weather   B. so a nice weather C. too nice weather      D. nice weather so解析：选A。因为此处weather是中心词，但它为不可数名词，所以不能加冠词。

Before作为连词的用法

重点句法：

It took nearly two hundred yearsbefore I was built as an analytical machine by Charles Babbage.

此句是 It+be/take+时间段+before句型

若主句是一般过去时从句也是一般过去时。若主句是肯定句翻译成“多长时间之后才”，若主句是否定形式翻译成“没过多久就”。所以，此句翻译为：差不多过了200年后，查尔斯.巴比奇才把我制成了一台分析机。

Before作为连词的用法

其基本含义是“在……之前”，又可以根据不同语境灵活翻译成“才”、“还没来得及就……”、“趁……”、“就”等。具体用法如下：

1、用于It+be/take+时间段+before句型

在这一句型中又可以根据主从句的时态分成两种情况。

A) 若主句是一般将来时态，从句是一般现在时。

若主句是肯定句意思是“要过多长时间才”;

若主句是否定形式译成“用不了多久就”。

It will be two weeks before everything returns to normal.两周之后一切才能恢复正常。

It will be many years before the situation improves.这种状况或许要过许多年才能得以改善。

It won't be long before we meet again.用不了多久我们就会再见面的。

It won't be 10 years before we catch up with the developed countries.用不了10年我们就会赶上发达国家的。

B)这时若主句是一般过去时从句也是一般过去时。

若主句是肯定句翻译成“多长时间之后才”，若主句是否定形式译成“没过多久就”。如：

It took nearly two hundred years beforeI was built as an analytical machine by Charles Babbage.差不多过了200年后，查尔斯.巴比奇才把我制成了一台分析机。

It was some time before I realized the truth. 过了很长一段时间我才了解到真相。

It was three years before I realized the importance of English. 过了三年时间我才意识到了英语的重要性。

After that it still took seven years before they got married. 他们又过了七年才结婚。

It wasn't long before she became a brave solider. 没过多久她就成了一名勇敢的战士。

注意：当主句的谓语动词为延续性动词时，before与until有时可以互换。

It was an hour before/until the police arrived.

2、 before与情态动词can/could连用

这时候从句虽为肯定形式，根据汉语表达习惯译成“还没来得及就”，如：

Before I could get in a word，he had measured me. 我还没来得及插话他就为我量好了尺寸。

Before she could move，she heard a loud noise，which grew to a terrible roar.她还没来得及迈步，就听见一声巨响，接着就是可怕的隆隆轰鸣。

3、before用于肯定句中强调主句所表达的时间、距离长，或花费的精力大，译成“才”

We had sailed four days and four nights before we saw lands.我们航行了四天四夜才看到陆地。

We waited a long time before the train arrived. 我们等了很长时间火车才到。

The Civil War lasted four years before the North won.

4、before用于否定句中，强调主句所表达的时间距离短，或花费的精力小，译成“不到……就”如：

We hadn't run a mile before he felt tired.我们跑了还不到一英里他就累了。

5、before用在“主句含有hardly，scarcely等半否定副词”的句中时，可以译为“刚……就”。句型是：

We had hardly done ...when...did

这时候主句应用过去完成时态，从句用过去时，还可以用when替代before如：

We had scarcely reached the school before/when the bell rang.我们刚到学校铃声就响了。

=Had we  scarcely reached the school before/when the bell rang.

6)用在含有before的主从复合句中用在含有before的主从复合句中，一般在从句中使用一般过去时，主句中使用过去完成时。例如：         Lily had written some letters before she went out shopping.有时，也可以在从句中用过去完成时，主句中用一般过去时，这样就可使描述更为生动。试比较：      We got to the station before the train had left. 火车尚未开动之前，我们就到了车站。      We had got to the station before the train left. 火车开出之前，我们就已经到了车站。像after一样， before本身就能明确地表示时间的先后关系，故多数主从句均使用一般过去时，而无需使用过去完成时。例如：，Many people left for home before the film ended.电影尚未放完，许多人就起身回家了。

连接：

by， before， when， until, after 在过去完成时态中应用

7、We had scarcely reached the school before/when the bell rang.有时还有“宁愿”的意思

I'd shoot myself before I apologized to him.我宁死也不向他道歉。
