二、语法规则理解
1.例句①②③⑤是________的省略。
2.例句④是________的省略。
微点拨 在英语句子中,用词简洁是一条重要的表达原则。省略是为了避免重复,突出关键词并使上下文紧密连接。经常在从句中使用,与主句配合,使句子富于变化,增强表现力。例如,在以than, as引导的比较状语从句中,一些成分往往被省略,这会给理解带来一定的影响,而且这类句子出现频率较高。
省略
一、状语从句中的省略
在as if, if, though, when, where, while, no matter what, until, as等引导的状语从句中,若谓语部分含有be动词,而主语又与主句的主语一致或从句主语是it时,从句的主语和谓语中的be动词可以一起省略。
❶When (she was) very young, she began to learn to play the piano.
她很小的时候就开始学习弹钢琴。
❷Don't come in until (you are) asked to.
不叫你时,请你不要进来。
❸He did as (he had been) told.
他按照被告知的那样去做了。
❹Though (they were) tired, they went on working.
虽然他们累了,但他们仍继续工作。
二、动词不定式的省略
1.感官动词see, hear, feel, watch等和使役动词have, make, let等后接不定式时,不定式省略to。
They made the boy go to bed early.
他们强迫这个男孩早睡。
2.do nothing but, can't help but等结构常接省略to的不定式。
We didn't do anything but stay at home watching TV yesterday.
昨天,我们没做任何事,只是在家看电视。
3.在特定语境中为了避免重复,当不定式再次出现时,在want, wish, hope, try, plan, like, love, hate后往往只保留to,而省略后面的动词。但不定式后有be, have时要保留be和have。
❶My parents encouraged me to go to college, but I didn't want to.
我父母鼓励我去上大学,但我不想去。
❷—Are you a teacher?
——你是老师吗?
—No, but I used to be (a teacher).
——不,但我以前是。
三、简单句中的省略
感叹句中常省略主语和谓语;在一些口语中可以省略某些句子成分。
❶What a hot day (it is)!多热的天啊!
How wonderful (it is)!多妙啊!
❷—(Will you) Have a smoke?——你抽烟吗?
—No. Thanks.——不,谢谢了。
❸We have nothing to do now but wait.
我们现在除了等没有别的事可做。
❹Why (do you) talk so much about it?
为什么大谈这件事呢?
四、并列句中的省略
1.如果主语不同,而谓语动词中的一部分相同,则省略谓语动词中相同的部分。
2.主语相同,谓语动词也相同,则两者均可以省略。
3.主语相同,而谓语不同,则可以省略主语。
4.在并列复合句中,如果that从句从属于第二个并列句且它的谓语动词和宾语等其他一些成分与第一个并列句相同时,这个that从句通常可以省略这些相同的部分。
❶John must have been playing football and Mary (must have been) doing her homework.
约翰一定在踢球,而玛丽一定在做作业。
❷Old McDonald gave up smoking for a while, but (he) soon returned to his old ways.
