SAT文法知识系列栏目说明:每期分享3-5个文法知识点,帮助大家更好地备考SAT。

一、连接词

1. 含义:

主要考察连词的句内关系和副词的句间关系。

2. 类型:

(1) 连词的句内关系

3.  用法

(1) 并列连词

① 连接两个独立的句子时,前面常加逗号。

例如1:Tom likes eating chips, but John likes biscuits.

(but连接两个独立的句子时,前面常有逗号,后面常无逗号。)

例如2:Tom gave her some coupons, and he used it to buy some groceries. 

(and在连接两个独立句子时,前面常有逗号,后面无。)

但若and后面有插入语时,可用逗号隔开。

例如3:Mary kicked the ball and, running fast, Tom chase it.

(and后面有插入语running quickly此时用逗号隔开。)

② 若连接的不是两个独立的句子,此时前后都不加逗号。

例如1:The athlete ran and jumped in the game.

(and连接的不是两个独立的句子,此时前后都不加逗号,因为ran and jumped是联合起来一起作the athlete的谓语,不可分隔。)

③ 在列举一系列的同等成分(三个及以上)时,并列前面常常用逗号隔开。

例如1:This dish contains chicken, curry and rice.

(在列举三项chicken, curry, and rice时,and在连接最后一项时,前面用了逗号。)

真题检测 1

(17-05NA Q10) Many communities in the United States could gain significant tourist revenue: if sites of natural beauty or historical significance—such as Idaho’s Boulder-White Clouds an Utah’s Cedar Mesa Plateau—were granted national park status.

A. NO CHANGE

B. revenue, if sites of natural beauty, 

C. revenue if sites of natural beauty,

D. revenue if sites of natural beauty

解析:通过if等选项看出是连词的考点,连词在句中,前面加逗号或不加逗号都可以,但不能加冒号,所以排除A;主语sites of natural beauty与谓语were granted之间不能加逗号,所以排除B/C三个选项,所以选D。

注:17-05NA Q10指2017年5月北美的第10题,下同。

真题检测 2

(16-06NA Q4) Batten, a careful planner, modified her plane with and additional propeller and fuel tank, and even changes were not enough to guarantee a successful flight.

A. NO CHANGE

B. but

C. or

D. when

解析:通过and等选项看出是连词的考点,前半句说Batten通过添加螺旋桨和油箱来改造她的飞机,而后半句说这些改变不足以确保一次成功的飞行,所以前后是转折关系,所以排除B/C/D三个选项,所以选A。

真题检测 3

(16-06NA Q30) Other composers followed suit, the cymbals became a regular fixture in orchestral percussion sections.

A. NO CHANGE

B. suit, thus

C. suit, and

D. DELETE the underlined portion

解析:通过and等选项看出是连词的考点,前后句是两个独立的句子,所以需要连词连接,所以A项的逗号和D项删除都不对;而thus是副词,不能分隔两个独立的句子,所以排除B选项,所以选C。

真题检测 4

(16-10AS Q5) The flashes disappeared within minutes but, their effects would later be felt on Earth for hours.

A. NO CHANGE

B. minutes, but their effects, 

C. minutes, but their effects

D. minutes; but their effects, 

解析:通过but等选项看出是连词的考点,but连接两个独立句子时,前加逗号后不加逗号,前面也不能是分号,所以排除A和D;主语effects与谓语would be之间不能用逗号隔开,所以排除B,所以选C。

真题检测 5

(16-10AS Q25) Let Us Now Praise Famous Men was published in 1941, but despite the attention that work accumulated, Many Are Called remained unpublished until 1966.

A. NO CHANGE

B. 1941, and

C. 1941; therefore, 

D. 1941: thus

解析:通过but等选项看出是连词的考点,前半句说Let Us Now Praise Famous Men的作品在1941年出版,而后半句说尽管这部作品积累了一些关注,但是Many Are Called这部作品直到1966年才出版,所以前后句是转折关系,所以排除B/C/D,所以选A。
