☆句型诠释☆

1. Next to him lay a cushion, upon which the man could work metal.

本句前半句为倒装句。正常的语序为A cushion lay next to him,倒装的目的是为了强调地点状语。In front of my house stands

a tall tree which can be seen from far away. / At the foot of the hill lies a large lake.

2. “……就……”英语表达法

(1) as soon as 归纳:

as soon as 引出的时间状语从句既可以放在主句之前,也可放在主句之后,表示它所指的动作发生在另一分句所指的动作之前。

as soon as 可以与动词的一般现在时,一般过去时或完成时态连用,主句的动词使用相应的动词现在时,过去时或将来时。

He started as soon as he received the news.

他一得到消息就出发了。As soon as he had got into the car, I said "good morning" to him in French and he replied in the same language. 他一上车,我就用法语向他道了声早安,他也用法语作了回答。

(2) hardly / scarcely / barely...when / before...no sooner... than...归纳:

注意搭配关系:hardly / scarcely / barely和no sooner不可以放在when / before和than之后。hardly / scarcely / barely和no sooner否定词位于句首时,句中的主语和谓语必须部分倒装。hardly / scarcely / barely和no sooner引导的是主句,表示它的动作发生在从句之前,故常用过去完成时;而when / before和than引导的从句只能与一般过去时连用。该句型含惊奇之意。Mrs Winthrop had no sooner left the room than they began to gossip about her.温思罗太太刚离开房间,他们就议论起她来了。Scarcely / Hardly / Barely had he begun to speak when I sensed that he was in trouble. 他刚一开口,我就感到他遇到麻烦事了。No sooner had we set out than a thunderstorm broke.我们一动身就遇上了大雷雨。

(3) the moment / the instant 归纳:名词短语the moment / instant / minute / second 和副词immediately / directly 可以用做连词,相当于as soon as,引导的是时间状语从句;从句既可放在句首,也可放在句中。The moment I saw him, I knew that there was no hope. 一见到他,我就知道没希望了。The instant you leave this tent, you will get a big surprise. 你一出帐篷,便会大吃一惊。We will leave the minute you're ready. 你一准备好,我们就走。She returned immediately she heard the bad news. 她一听到这个坏消息,就返了回来。I left directly the clock struck twelve. 钟一敲十二点我就离开了。

(4) on + 动名词(或表示动作的名词)归纳:动名词(或名词)结构表示它所表达的动作刚一发生或完成,句子谓语所表示的动作就接着发生。它相当于as soon as 引导的时间状语从句。On arriving in England, they were taken to the Crystal Palace by train. 他们一到英国便乘火车去水晶宫。He was greeted by the Prime Minister on his arrival at the airport. 他一到机场,便受到总理的欢迎。

另外,each time,every time 如同上面四种类型一样,可直接用作从属连词,引导状语从句。Every time I listen to his advice, I get into trouble. 我每次听了他的劝告,都会遇到麻烦。I'll think of my hometown each time I listen to that song. 我每次听这首歌,都会想起家乡。

3. as...as... 与比较级的用法

(1) ...as + 形容词(副词)原级+ as...;not as / so + 形容词(副词) 原级+ as... I study as hard as you. 我学习和你一样努力。He doesn't get up as / so early as his parents.他起床没有他父母亲早。

(2)……倍数+ as + 形容词(副词)原级+ as... Line AB is 3 times as long as Line CD. = Line AB is twice longer than / 3 times the length of Line CD. 线段AB是线段CD的三倍长。

(3) as + 形容词+ a / an + 单数可数名词+ as;as + 形容词+ 复数名词+ as I haven't got as much money as I thought. 我的钱没有我想像的那么多。

(4) as much / many as 多达……,……那么多This factory produces as much as 100 tons of steel a day. 这家工厂每天产铁100 吨。As many as 700 different languages are spoken in Africa. 在非洲人们所说的语言多达700多种。

5. x times + n. 通过结构,应掌握英语里表示倍数的表达句型。

A is x times the size (height, length, width...) of B.

A is x times as big (high, long, wide...) as B.

A is x times + adj.-er than B.

The size (height, length, width...) of A is x times that of B.

The meeting-room is three times the size of our office. = The size of the meeting-room is three times that of our office.

三倍以下通常用double或者twice来表达两倍。His weight is double what it was ten years ago. / This railway is twice longer than that one. / The room is twice the size of that one. = This room is twice as big as that one.

☆句型归纳☆

【考点1】As far as I know... 据我所知……

as far as是连词,本意为“和……一样远”。引申意为“就……(程度,范围) 而言,至于,尽……”。类似的还有:as long as“和……一样长”。“只要”;as good as“和……一样好”。“实际上,事实上,和……几乎一样”;as well as “和……一样好”,“既……又……,不但……而且……”。例如:As far as I know, he isn't coming to the party. 就我所知,他不会来参加这次聚会。

As far as he is concerned, he can't afford such an expensive car. 就他而青,他买不起这么贵的汽车。

【考例1】(2004北京、安徽) ____ I can see, there is only one possible way to keep away from the danger.

A. As long as

B. As far as

C. Just as

D. Even if

[考查目标] 本题考查连词的用法。

[答案与解析]B 选项A中的as long as 表示“只要”;选项B中的as far as 跟其后的I can see 一起表示“据我看,据我所知”;选项 C 中的Just as表示“就在……时”;选项D中的Even if表示“即使”。

【考点2】lf you offered me six times what you have just offered, I would still take my pound of flesh. 如果你给我已经支付的六倍的钱。我还是要拿走我的那磅肉。倍数的表达方式有如下几种:

① A + be + 倍数+ the + 长(宽、高)的名词形式+ of + B。例如:

The new building is four times the size of the old one. 新房的面积是旧房的四倍。

② A + be + 倍数+ 形容词或副词的比较级+ than + B。例如:The sun is a million times larger than the earth. 太阳比地球大100万倍。

③ A + be或其他动词+ 倍数+ as + 形容词或副词的原级+ as + B。例如:The car runs three times as fast as I walk. 汽年行驶的速度是我走路的三倍。

【考例2】(2004全国卷III) It is reported that the United

States use ____ energy as the whole of Europe.

A. as twice

B. twice much

C. twice much as

D. twice as much

[考查目标]本题考查倍数的表达方式。

[答案与解析]D 表示倍数的名词要放在as...as的前面。

【考点3】We can find several such ideas in Shakespeare's play The Merchant of Venice. 在莎士比亚的作品《威尼斯商人》中。我们可以找到好些这样的理念。

在本句中find表示“找到,发现,发觉,感到”,后接名词、形容词、副词、现在分词、过去分词、介词短语等作宾语补足语。例如:Tom has found his short-wave radio very helpful. 汤姆发觉短波收音机很有用。Jim found it hard to take the crowded bus. 吉姆觉得很难搭上拥挤不堪的公车。

【考例3】(NMET 2003) A cook will be immediately fired if he is found ____ in the kitchen.

A. smoke

B. smoking

C. to smoke

D. smoked

[考查目标]本题考查find后接宾语补足语的用法。

[答案与解析]B find后接现在分词作宾语补足语时,表示动作正在进行;接过去分词作宾语补足语时,表示动作的“完成和被动”。根据语境可知,厨师在厨房抽烟要被开除,但是要抓住把柄.只能是他“正在抽烟”。

【考点4】For trade and cultural links as well as life in Britain and the construction of a building such as Stone- henge。people in the Bronze Age must have had knowledge about certain things and certain fields of science. 鉴于贸易与文化的联系及英国生活和像巨石阵的建筑结构。青铜时代的人一定了解很多事情并对一些科学领域有所涉及。

must可以用来表示对事情的肯定的推测:对现在的推测用must + 原形动词,对过去发生的事情的推测用must + have done。如果把握不大,则可用may / might + 原形动词表示对现在的推测,用may / might + have done 表示对过去的推测。而can / could + 原形动词(表示对现在的推测)以及can / could + have done (表示对过去的推测)一般用于否定或疑问句。例如:It is possible that the King of Stonehenge was linked to the stones: he may have had a hand in planning the monument, or in helping transport and pull up the stones. 可能这个巨石王和这些石头有关系:他可能参与策划建立这个纪念碑,或者帮助运输和竖起巨石。It must have rained last night, for the ground is wet. 地上是湿的,昨晚一定下雨了。

【考例4】(2003上海)My English-Chinese dictionary has

disappeared. Who ____ have taken it?

A. should

B. must

C. could

D. would

[考查目标]本题考查不同的情态动词在推测(或猜测)句型中,分别表示不同把握(或语气)程度的区别。

[答案与解析]C should have done表示“本来应该做某事而实际上来做”;must have done 表示“一定做了某事”;could have

done表示“可能做了某事”,同时,could用于疑问句;would have done表示“应该会做某事”。根据上下文语境“我的英汉词典不见了”,可知“可能会是谁拿走的呢?”

【考点1】如何用英语表达失望

(2005名校示范卷)

-- Give me two tickets for the 8 : 00 show.

-- The 8 : 00 show tickets are sold out.

-- ____.

A. Thank you.

B. Why didn't you keep one for me?

C. What a shame!

D. Never mind.

[答案与解析]C 这道题考查的是英语中失望的表达方式。根据上下文可知。一方想“买两张演出票”,而对方却说“票卖完了”,那么买票方的反应会是“真可惜! (C项)”而不可能是“谢谢(A项)”、或质问对方“为什么不给我留票?(B项)”或“没关系(D项)”。故只有C项正确。

【归纳】人在生活中经常会遇到让人失望的事情,在英

语中用来表达失望的方式有:

①What a shame! ②What a pity!

③It's a pity / shame that...

④Everybody will be disappointed..

【归纳】常见的表达因没弄明白或是出于好奇而“想知道”的方式还有:

①I wonder what / who-- ②I'm curious to...

③I wonder if / whether ④I'm curious about...

⑤I really want to know... ⑥I'd love to know...

☆精典题例☆

( ) 1. ____ you've got a chance, you might as well make fun use of it.

A. Now that

B. After

C. Although

D. As soon as

【解析】选A 本题的意思是“既然你已得到一次机会,你还是充分利用它为好”。可以看到,句中含有一个状语从句。now that = since意为“既然”。

( ) 2. With the old stone bridge ____, a new steel one was going to be built there.

A. torn down

B. tearing down

C. was torn down

D. being torn down

【解析】选A 该题考查with + 宾语+ 宾语补足语

这一结构。tear down是“拆毁”的意思。bridge与tear down

是被动关系,因此tear down应用过去分词,即torn down。

( ) 3. While watching television, ____. (2005全国III)

A. the doorbell rang

B. the doorbell rings

C. we heard the doorbell ring

D. we heard the doorbell rings

【解析】选C 分词短语充当状语,其逻辑主语是句

子的主语。如果选A、B,watching的逻辑主语则是the

doorbell。不符合逻辑。We heard the doorbell ring. 其意是“我们听到铃声响了”,ring是宾语补足语。

( ) 4. It is known to all that ____ you exercise regularly, you won't keep good health. (2005重庆)

A. unless

B. whenever

C. although

D. if

【解析】选A unless意思为“如果……不(if…not)。本题意思是“众所周知,要是你没有经常锻炼,你就不能保

持健康。”

A. drove; didn't get

B. drove; wouldn't get

C. were driving; wouldn't get

D. had driven; wouldn't have got

【解析】选D 含有if从句的虚拟语气表示过去发生

的事,从句用过去完成时,主句用过去将来完成时,即

would + have + 过去分词。这句话意思是:你不让我开

车。如果我们轮流开车,你不会那么累。

( ) 6. He hurried t0 the station only ____ that the train had left. (2005广东)

A. to have found

B. finding

C. found

D. to find

( ) 7. The matter____ your fate cannot be taken for

granted.

A. relating to

B. related to

C. relate to

D. to relate to

【解析】选B 该题考查动词relate用法。relate to “与…有关”,此处是过去分词作matter的后臵定语,相当于一个定语从句:The matter which / that is related to your fate...taken for granted“想当然”。由此句可以判断B正确答案。

( ) 8. If you keep on, you'll succeed ____.

A. in time

B. at one time

C. at the same time

D. on time

【解析】选A 该题考查介词短评的辨析。in time有“及时”之意,还有“迟早、总有一天”的含义,相当于sooner or later。其

他选项均不合题意。

有机化合物知识点归纳总结

第三章有机化合物1、 反应条件或可逆符号打不上自己补上:) 4、同系物、同分异构体、同素异形体、同位素比较

1 2、乙醇、水、碳酸、乙酸中羟基氢原子的活泼性 O=O= CH3CH2—OH,H—OH,HO-C-OH(碳酸),CH3-C--OH中均有羟基, 由于这些羟基相连的基团不同,羟基上氢原子的活动性也就不同,现比较如下:

3、乙醇与乙酸的酯化反应:原理酸脱羟基醇脱氢。 酯化反应也属于取代反应,它是取代反应中的一种。 CH 3COOH+C 2H 5OHCH 3COOC 2H 5+H 2O 实验装置图: 实验中的注意事项(这是本节知识的考点) 1、加药品的先后顺序:乙醇、浓硫酸、冰醋酸。 2、浓硫酸的作用:催化剂(加快反应速率)、吸水剂(使可逆反应向生成乙酸乙酯的方向移动)。 3、加热的目的:加快反应速率、及时将产物乙酸乙酯蒸出以利于可逆反应向生成乙酸乙酯的方向移动。(注意:加热时须小火均匀进行,这是为了减少乙醇的挥发,并防止副反应发生生成醚。) 4、导气管伸到饱和碳酸钠溶液液面上的目的:防止受热不均引起倒吸。 5、饱和碳酸钠溶液的作用:吸收未反应的乙酸和乙醇、降低乙酸乙酯的溶解度使之易分层析出。 6、不能用NaOH 溶液代替饱和碳酸钠溶液:因为NaOH 溶液碱性强促进乙酸乙酯的水解。 7、提高乙酸乙酯的产率的方法:加入浓硫酸、加入过量的乙酸或乙醇、及时将产物乙酸乙酯蒸出。 4 、酯化反应与酯水解反应的比较 浓硫酸 △

蛋白质盐析和变性的比较 淀粉、纤维素水解实验的注意问题 (1)淀粉、纤维素水解都用H2SO4做催化剂,但淀粉用 20%H2SO4,纤维素用90%H2SO4,均需微热; (2)检验产物时,必须用 ...NaOH ........,才能用银氨溶液或新制Cu(OH)2,进行检验。 ....溶液中和过量的酸 (3)淀粉是否发生水解的判断: 利用淀粉遇碘变蓝的反应和其水解最终产物葡萄糖能发生银镜反应来判断淀粉是否发生水解和水解进行程度。 如淀粉没有水解,则不能发生银镜反应;如淀粉已完全水解,则遇碘不能变蓝色;如既能发生银镜反应,又能遇碘变蓝色,则说明淀粉仅部分水解。 有机化合物燃烧规律 有机化合物的燃烧涉及的题目主要是烃和烃的衍生物的燃烧。烃是碳氢化合物,烃的衍生物主要是含氧衍生物,它们完全燃烧的产物均为二氧化碳和水,题目涉及的主要是燃烧的耗氧量及生成CO2和H2O的量的问题。 设烃的通式为:C x H y, 烃的含氧衍生物的通式为:C x H y O z 烃燃烧的通式:CxHy+(x+y/4)O2=xCO2+y/2H2O 烃的含氧衍生物燃烧的通式:CxHyOz+(X+Y/4-Z/2)O2→xCO2+y/2H20 (1)比较有机物燃烧的耗氧量,以及生成的CO2和H2O的量的相对大小:根据上述两燃烧通式可归纳出以下规律: ①等物质的量的烃完全燃烧时的耗氧量,取决于(x+y/4) 的值,生成的CO2和H2O的量取决于x和y的值。还

有机化合物知识点总结三资料

有机化合物知识点总结(三) 绝大多数含碳的化合物称为有机化合物,简称有机物。像CO、CO2、碳酸、碳酸盐、金属碳化物等少数化合物,它们属于无机化合物。 一、烃 1、烃的定义:仅含碳和氢两种元素的有机物称为碳氢化合物,也称为烃。 2、甲烷、乙烯和苯的性质比较:

乙烯 1.氧化反应 I .燃烧 C 2H 4+3O 2??→ ?点燃 2CO 2+2H 2O (火焰明亮,伴有黑烟) II .能被酸性KMnO 4溶液氧化为CO 2,使酸性KMnO 4溶液褪色。 2.加成反应 CH 2=CH 2+Br 2?→? CH 2Br -CH 2Br (能使溴水或溴的四氯化碳溶液褪色) 在一定条件下,乙烯还可以与H 2、Cl 2、HCl 、H 2O 等发生加成反应 CH 2=CH 2+H 2 催化剂 △ CH 3CH 3 CH 2=CH 2+HCl 催化剂 △ CH 3CH 2Cl (氯乙烷:一氯乙烷的简称) CH 2=CH 2+H 2O 高温高压 催化剂 CH 3CH 2OH (工业制乙醇) 3.加聚反应 nCH 2=CH 2 催化剂 △ (聚乙烯) 注意:①乙烯能使酸性KMnO 4溶液、溴水或溴的四氯化碳溶液褪色。常利用该反应鉴别烷烃和烯烃,如鉴别甲烷和乙烯。②常用溴水或溴的四氯化碳溶液来除去烷烃中的烯烃,但是不能用酸性KMnO 4溶液,因为会有二氧化碳生成引入新的杂质。 苯 难氧化 易取代 难加成 1.不能使酸性高锰酸钾褪色,也不能是溴水发生化学反应褪色,说明苯的化学性质比较稳定。 但可以通过萃取作用使溴水颜色变浅,液体分层,上层呈橙红色。 2.氧化反应(燃烧) 2C 6H 6+15O 2??→ ?点燃 12CO 2+6H 2O (现象:火焰明亮,伴有浓烟,说明含碳量高) 3.取代反应 (1)苯的溴代: (溴苯)+ Br 2 FeBr 3 +HBr (只发生单取代反应,取代一个H ) ①反应条件:液溴(纯溴);FeBr 3、FeCl 3或铁单质做催化剂 ②反应物必须是液溴,不能是溴水。(溴水则萃取,不发生化学反应) ③溴苯是一种 无 色 油 状液体,密度比水 大 , 难 溶于水 ④溴苯中溶解了溴时显褐色,用氢氧化钠溶液除去溴,操作方法为分液。 (2)苯的硝化: + HO -NO 2 浓H 2SO 455℃~60℃ -NO 2 + H 2O ①反应条件:加热(水浴加热)、浓硫酸(作用:催化剂、吸水剂) ②浓硫酸和浓硝酸的混合:将浓硫酸沿烧杯壁慢慢倒入浓硝酸中,边加边搅拌 ③硝基苯是一种 无 色 油 状液体,有 苦杏仁 气味, 有 毒,密度比水 大 ,难 溶于水。 ④硝基苯中溶解了硝酸时显黄色,用氢氧化钠溶液除去硝酸,操作方法为分液。 (3)加成反应(苯具有不饱和性,在一定条件下能和氢气发生加成反应) + 3H 2 Ni (一个苯环,加成消耗3个H 2,生成环己烷) 4、同系物、同分异构体、同素异形体、同位素比较。 概念 同系物 同分异构体 同素异形体 同位素
