①.My whole life, brief as it was, had been spent in that big old house, gracefully touched with the laughter andtears of four generations.分清主干my whole life had been spent和修饰关系gracefully touched with the laughter and tears of four generations 非限制性是定语从句,修饰that big old house②.I see such a difference in New York City, for example, from when I first moved here more than 20 years ago:people rushing into elevators without giving those inside a chance to get off first, never saying “Thank you.”when others hold a door open for them, or “Please.” when they want a coworker to hand them something, never giving a wave or nod of appreciation when another motorist lets them pull out into traffic.分清层次never 与never 并列,saying 的宾语有两个,由or连接,而people统辖的内容有三个rushing into…, never saying…, never giving…,并与此三个部分构成动名词复合结构,相当于说I saw a scene of people rushing…③.It adds priceless panache (n.) to your understanding of the way people behave.注意add sth. to 分割的状况II. 词法部分1.名词与代词1)不可数名词的量化表示修饰可数名词复数: many, a good/great many,a good/great/large number of修饰不可数名词: much, a great deal of, a large amount of两者都可修饰: a lot of, lots of, plenty of, a great/large quantity of, quantities of, a large sum of2)在汉语中可数,但在英语中为不可数名词的某些词advice, baggage (luggage), damage, equipment, furniture, homework, information, news ...3) 与所指代的名词在性、数、格上是否一致如:Each cigarette a person smokes does some harm, and eventually he may get a serious disease from its effect.It was during the 1920’s that the friendship between the two American writers Hemingway and Fitzgerald reached its highest point.4) that, one的指代作用that指代不可数名词和单数可数名词(如是复数,用those),后面通常跟有修饰语,如出现在比较结构中的that of。

专四语法考点串讲语法回顾篇:专四语法考点虚拟语气、情态动词、非谓语动词、复合句、倒装、小语法(省略,时态,反义疑问句,代词,强调句,主谓一致,冠词,形容词及副词)、as 的特殊用法。
专四英语语法考点串讲之一虚拟语气一般说来,有下列几种考点需要考生注意(十考点及两备考点)考点1. 与现在事实相反从句谓语动词用did(be用were),主句谓语动词would(should,could,might)+do;考点2. 与过去事实相反从句谓语动词用had done,主句谓语动词用would(should,could,might)+ have done;例如:43.I _________the party much more if there hadn’t been quite such a crowd of people there.A. would enjoyB. will have enjoyedC. would have enjoyedD. will be enjoying49.All of us would have enjoyed the party much more if there _________ quite such a crowd of people there.A. weren’tB. hasn’t beenC. hadn’t beenD. wouldn’t考点3.与将来事实相反,从句谓语动词用:did(should+do或were + to do),主句谓语动词用:would(should,could,might)+do。
例如:43. If your car ___ any attention during the first 12 months, take it to an authorized dealer.(08年)• A. shall need C. would need• B. should need D. will need考点4. 时态的交叉现象,也就是主句与从句的动作发生在不同的时间段例如:If you had gone to see the doctor,you would be all right now.你要是早去看病,你现在就没事了。
1.nothing but意“ ,只不〞;anything but意“除⋯之外的任何事〞;none other than意“不是人,正是⋯〞; no more than意“不,〞。
2.A. taxes B. payment 付款 C. fees 手、入、会 D. premium津酬金3. A. display 显现型表演 B. performance 文表演 C. show 展会 D. exhibition售性的展会4.No one would have time to read or listen to an account of everything ____going on in the world.A. it isB. as isC. there is在以there be的定从句中,如关系代作主,关系代即可省略 D. what is5.

12.know better than to do sth知道不做某事13. in one’ s honor⋯的荣誉on one ’ s honor以名誉担保 a point of honor 涉及荣誉的事14.might as well 后接原形,意“不如,何不〞15.call for 意“要求,需要〞; call on 意“号召,求〞 ;callup 意“令人想起〞;call off意“取消,停止做〞。
独立主格结构独立主格结构(Independent Genitive)有两部分组成,前一部份是名词或者代词,后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。
前后两部分具有逻辑主谓关系。
独立主格结构在句中做状语,多用于书面语。
独立主格结构本身不是句子,在句子中作状语,表示时间、原因、条件、伴随、目的等。
非谓语动词作状语,其逻辑主语须与主句主语保持一致。
若不一致,非谓语动词形式须另带主语,从而构成复合结构的形式作状语。
这种结构称为“独立结构”。
其中,非谓语动词主动用现在分词,被动用过去分词。
非谓语动词及其短语前面带有逻辑主语,逻辑主语的代词又是主格,故常称为“独立主格”。
“独立结构”在句中起状语作用,相当于状语从句,表示时间、原因、条件、方式或伴随等情况。
功能独立主格结构主要用于描绘性文字中,其作用相当于一个状语从句,常用来表示时间、原因、条件、行为方式或伴随情况等。
例如:表示时间The meeting being over, all of us went home. 开完会后我们都回家了。
Her work being done, she sat down for a cup of tea. 她干完了活,坐下来喝茶。
表示条件The condition being favorable, he may succeed. 若条件有利,他或许能成功。
表示原因There being no taxis, we had to walk. 没有出租车,我们只好步行。
He wrapped her up with great care, the night being dark and frosty. 夜又黑又冷,所以他把她裹得严严实实的。
表示伴随情况Almost all metals are good conductors, silver being the best of all. 几乎所有的金属都是良导体,而银则是最好的导体。
