难点突破

一.长难句分析

1. Fredrick William I, the King of Prussia, could never have imagined that his greatest gift to the Russian people would have such an amazing history. 普鲁士国王威廉一世绝不可能想到他送给俄罗斯人民的厚礼会有这样一段令人惊讶的历史。

could never have imagined 过去不可能想到

情态动词+ have done 表示对过去所发生的事情的推测,现归纳如下:

must + have done只用于肯定句,意思是"过去一定做过"。

can't +have done "过去不可能做过,肯定没做过",是must + have done的否定形式。

should (ought to) + have done 表示"本来应该做而实际上没做",含有责备的语气。

should not (ought not to) + have done则表示"本来不该做而实际上做了",含有责备的语气。

could + have done 表示"本来有能力做而实际上没有做"。

needn't + have done 表示"本来不必做的事,实际上做过了。"

would like to have done 表示"本来希望做而却未做的事"。

may (might) + have done表示对过去的推测,多用于陈述句,意思是"可能……"。might 比may 语气更加委婉。 例如:

例1. (2007福建) ---Where is my dictionary? I remember I put it here yesterday.

--- You ______ it in the wrong place.

A. must put B. should have put C. might put  D. might have put

解析:答案是D。might have done表示过去可能做过的事。

例2. (2007上海)---Guess what! I have got an A for my term paper.

---Great! You _____ read widely and put a lot of work into it.

A. must B. should   C. must have  D. should have

解析:答案是C。此句意为"你肯定读了很多书",对过去发生的事情进行推测用must have done。

例3. (2008重庆)---I can't find my purse anywhere.

---You       have lost it while shopping.

A. may  B. can  C.  should   D. would

解析:答案是A。此句意为"你可能购物时丢了它了",过去可能发生的事情用may have done。

例4. (上海 2000) My sister met him at the Grand Theater yesterday afternoon, so he ______  your lecture. ?

A. couldn't have attended   B. needn't have attended

C. mustn't have attended   D. shouldn't have attended

解析:答案是A。此句意为 "我妹妹昨天下午在大剧院碰见他了,所以他不可能听了你的讲座。" 表示过去不可能做了用"can't / couldn't have done"。

2.…which took the country's best artists about ten years to make. 它花了这个国家最好的艺术家十年的时间建造的。

take 表示" 需要,花费",常用句型为"It takes sb some time to do sth."例如:

It took him all afternoon to finish the task.  他用了整个下午才完成这件工作。

Courage is what it takes to succeed.       成功需要勇气。

3.  About four meters long, the room served as a small reception hall for important visitors. 琥珀屋长约四米,被当作了接待厅接见重要客人。

表示某物的长,宽,高的结构为:数词+量词+ long/ wide/ high

或:数词+量词+ in length/ width/ height

例:--- ______ is the height of the mountain?

---It's 8848 meters ______.

A. How tall; high B. What; tall C. What; in height D. What high; high

解析:答案是C。高度是多少用what提问,第二空可填high或in height。

4. This was a time when the two countries were at war. 这是两国交战的时期。

① a time 表示一段时间,为先行词,when 引导定语从句,when在定语从句中作时间状语。

考题:There was ______ time ______ I hated to go to school.

A. a, that B. a, when C. the, that D. the, when

解析:答案是B。此题结构和所分析的句子完全相同。

② at war (with) (和…)处于交战状态,war前不要冠词。其他"介词+冠词"表状态的短语有:

at:  at work在工作/ at table 在吃饭/ at play 在玩耍

on:  on show 在展出 / on duty值班/ on sale 出售;贱卖/ on holiday 在度假/ on fire在燃烧 / on watch值班,放哨/ on trial受审/ on business 因公,因事/ on guard 警惕,防范

in:  in trouble在麻烦中 / in danger 处于危险中/ in battle 在交战/ in doubt怀疑,不确定/ in order 秩序井然,整齐/ in secret 秘密地,私下地/ in debt 欠债/ in shape 处于良好状态/ in anger愤怒地/ in poverty 在贫困中

under:  under repair在修理中 / under discussion正被讨论 / under construction正在建造中 / under treatment 正被治疗under control 被控制住

5. The Russians were able to remove some furniture and small art objects from the Amber Room. 俄罗斯人民从琥珀屋移走了一些家具和小艺术品。

was/ were able to 表示过去经过努力,成功地做了某事,表达一种结果。类似于succeeded in doing 或managed to do的含义。如:

He worked very hard, and was able to pass the examination.

他学习很努力,因而通过了考试。

考题: The fire spread through the hotel very quickly but everyone ______ get out.

A. had to     B. would     C. could   D. was able to

解析:答案是D。此题意为"大火迅速在宾馆蔓延开,但人们都成功地逃出去了",表示过去成功地做了某事只能使用was / were able to do,故本题选D。

二.词语辨析:

1. worth, worthy, worthwhile

(1)worth:

①只作表语,有某种价值

The picture is worth $ 500. 这幅画值500 美元。

② be worth doing 值得做某事 (其后接动名词时,总是用主动形式表示被动意义。)

The clock is hardly worth repairing. 这台钟简直不值得修理。

What is worth doing is worth doing well. 值得干的事就得干好。

Nothing he said was worth listening to. 他说的话没有一句值得听。

③ worth 习惯上不用 very 修饰,要表示类似意思可用 well。如:

④作定语,值得尊重和考虑的,如:a worthy course 崇高的事业,

It is worthwhile buying/ to buy the dictionary. 这本词典值得买。

②作定语,如:

补充说明:在很多情况下,同一个意思可用几种不同的形式表达。如:那个地方值得一去。正:The place is worth a visit.

正:The place is worth visiting.

正:It is worth visiting the place.
