職稱英語考試中，為了避免不必要的重復，經(jīng)常用so，not，to，do，does 代替前面出現(xiàn)的動詞或相關內(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 代替動詞。
(2)“so 與 not” 代替某個詞、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” 用來代替動態(tài)動詞，而不能代靜態(tài)動詞。
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)動詞。)
(5)為使語言精煉，避免不必要的重復，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.)
