代替與省略

    英語(yǔ)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。
    (1) 從上兩例中看出，do / does / did 代替動(dòng)詞。
he translated the article better than i did.   （did代替wrote it）
— do you think she is clever?
— i think so.   （so代替 she is clever）
    (2) "so 與 not" 代替某個(gè)詞、短語(yǔ)、句子等，通常用于hope, think, believe, expect, suppose, be afraid, fear, imagine, etc后作賓語(yǔ)。
— 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.
 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(lái)代替動(dòng)態(tài)動(dòng)詞，而不能代靜態(tài)動(dòng)詞。
— 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(yǔ)言精煉，避免不必要的重復(fù)，對(duì)話中常用省略形式。
— 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.）
