新SAT资讯分享
周五啦~大家这一周都辛苦了呢!有些同学也许已经在陆陆续续进入了final,有些同学应该马上就要开始prom了。所以就在这个比较混乱的时间点,课代表来帮助大家,重新整合一下关于SAT语法的各种题型吧!
SAT语法 独立主格结构
- 独立主格结构的逻辑主语与句子的主语不同,它独立存在。
- 名词或代词与后面的形容词、副词、介词短语、分词、不定式等存在逻辑上的主谓关系。
- 独立主格结构一般用逗号与主句分开,但与主句之间不能使用任何连接词。
The work done(=After the work had been done) , we went home. 工作完成后,我们才回家。
(2) 作条件状语
Weather permitting(=If weather permits) , they will go on an outing to the beach tomorrow. 如果天气允许的话,他们将在明天组织一次海滨小游。
(3) 作原因状语
An important lecture to be given tomorrow(=As an important lecture will be given tomorrow) , the professor has to stay up late into the night. 因为明天要发表一个重要的演讲,教授不得不熬夜到很晚。
(4)作伴随状语
He was lying on the grass, his hands crossed under his head(=and his hands were crossed under his head) . 他躺在草地上,两手交叉枕在脑后。
(5)表补充说明
A hunter came in, his face red with cold(=and his face was red with cold) . 一个猎人走了进来,他的脸冻得通红。
The president assassinated, the whole country was in deep sorrow.
2.动词不定式表示动作没有发生或即将发生,动词-ed形式表示动作已经结束,动词-ing形式往往表示动作正在进行。
The manager looks worried,many things to settle.
(事情还没有处理,而且是由经理本人来处理,用不定式to settle,表示将来的时间)
The manager looks relaxed, many things settled.
(事情已经处理好了,用过去分词settled表示动作已经结束)
The food being cooked, the boy was watching TV.(两个动作同时进行)
3.独立主格结构与分词短语都可以转换为状语从句。但是独立主格结构转换为状语从句后,它有自己的逻辑主语,与主句的主语不一致;而分词短语转换为状语从句后,从句的主语与主句的主语一致。
If time permits, we’d better have a holiday at weekends.(条件状语从句)
Time permitting, we’d better have a holiday at weekends.(独立主格)
When we see from the hilltop, we can find the city more beautiful.(时间状语从句)
Seeing from the hilltop, we can find the city more beautiful.(现在分词)
