高考臨近,小編為大家準(zhǔn)備了些高考短語及其用法和搭配,希望大家能從中獲益!
dozen可用復(fù)數(shù)嗎?dozen后要接of嗎?你知道dozen的用法嗎?請(qǐng)先看下面一道試題:
We already have _________ pencils, but we need two _________ pens.
A. dozen of, dozen B. dozens of, dozens C. dozens of, dozen D. dozens of, dozen of
此題最佳答案為C。關(guān)于dozen的復(fù)數(shù)是否加詞尾-s的問題比較復(fù)雜,大致原則是:
1. 當(dāng)它與具體數(shù)字連用時(shí),既不加復(fù)數(shù)詞尾-s,也不后接介詞of。盡管有的詞書也有 two dozen of 這樣的用例,但這已屬過時(shí)用法,在考試中應(yīng)避免,如1992年全國高考有一道單項(xiàng)選擇題就認(rèn)為two dozen of為錯(cuò)誤選項(xiàng):
Shortly after the accident, _________ police were sent to the spot to keep order.
A. dozens of B. dozens C. dozen of D. dozen [D]
2. 當(dāng)它不與具體數(shù)字連用,而是表示不確定的泛指數(shù)時(shí),則不僅要加復(fù)數(shù)詞尾-s,而且要后接介詞 of,此時(shí)可將dozens of(許多,幾十)視為習(xí)語。如:
I’ve been there dozens of times. 我去過那兒幾十次。
She’s got dozens of boy-friends. 她的男朋友很多。
下面一例中的dozens加了復(fù)數(shù)詞尾-s也屬為似情況:
Pack them in dozens. 按打裝袋吧。(from www.nmet168.com)
3. 當(dāng)與 a few, several 等數(shù)目不很具體的詞連用時(shí),加不加復(fù)數(shù)詞尾-s均可,但需注意:不加復(fù)數(shù)詞尾-s時(shí),其后的介詞of可以省略;加詞尾-s時(shí),其后介詞 of不能省略。如:
several dozen (of) pencils=several dozens of pencils幾打鉛筆
注:英語較少使用many dozen的說法,要表示類似意思可用dozens of。
4. 當(dāng)它后面的名詞受 the, these, those 等特指限定詞修飾時(shí),或其后的接的是us, them這樣的人稱代詞時(shí),則此時(shí)必須用介詞 of。如:
two dozen of these eggs 兩打這種雞蛋
three dozen of them 它們中的3打
注:score, hundred, thousand, million等也具有以上類似用法。
