2015年職稱英語考試語法備考：代替與省略
職稱英語考試中，為了避免不必要的重復(fù)，經(jīng)常用so，not，to，do，does 代替前面出現(xiàn)的動(dòng)詞或相關(guān)內(nèi)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)從上兩例中看出，do / does / did 代替動(dòng)詞。
（2)“so 與 not” 代替某個(gè)詞、短語、句子等，通常用于hope，think，believe，expect，suppose，be afraid，fear，imagine，etc后作賓語。
E.g. —Is it correct?
—I'm afraid not. （not correct)
（3)“to” 用作不定式，常跟隨下列動(dòng)詞：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” 用來代替動(dòng)態(tài)動(dòng)詞，而不能代靜態(tài)動(dòng)詞。
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屬靜態(tài)動(dòng)詞。)
（5)為使語言精煉，避免不必要的重復(fù)，對話中常用省略形式。
E.g. —He is thinking of buying a car?
—Is he?（這里，“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.)
