2015年职称英语考试语法备考：代替与省略
职称英语考试中，为了避免不必要的重复，经常用so，not，to，do，does 代替前面出现的动词或相关内容。
如：He translated the article better than I did.（did代替wrote it)
—Doyou think she isclever?
—I think so.（so代替 she is clever)
（1)从上两例中看出，do / does / did 代替动词。
（2)“so 与 not” 代替某个词、短语、句子等，通常用于hope，think，believe，expect，suppose，be afraid，fear，imagine，etc后作宾语。
E.g. —Is it correct?
—I'm afraid not. （not correct)
（3)“to” 用作不定式，常跟随下列动词：want，mean，hope，expect，refuse，seem，intend，be，afraid，etc.
E.g. I asked him to go to the party，but he refused to. （go to the party)
（4)“do so，do that，do it” 用来代替动态动词，而不能代静态动词。
Eg. —He gave up studying English.
—Why did he do so?（= give up studying English)
—The dish tastes nice.
—Yes，so it does.（tastes nice)
（此句不能用it does it 或 it does so，因taste属静态动词。)
（5)为使语言精炼，避免不必要的重复，对话中常用省略形式。
E.g. —He is thinking of buying a car?
—Is he?（这里，“thinking of buying a car”被省略了。)
—Will he come back in time?
—Perhaps.（省略了he will come back in time.)
