dozen的用法
? dozen可用復(fù)數(shù)嗎?dozen后要接of嗎?你知道dozen的用法嗎?請先看下面一道試題: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,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,但這已屬過時用法,在考試中應(yīng)避免,如1992年全國高 lang=EN-US style="FONT-SIZE: 10.5pt; FONT-FAMILY: 'Times New Roman'">1992two dozen of為錯誤選項: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,則不僅要加復(fù)數(shù)詞尾-s,而且要后接介詞 of,此時可將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。
3. 當(dāng)與 a few, several 等數(shù)目不很具體的e="FONT-SIZE: 10.5pt; FONT-詞連用時,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,其后的介詞of可以省略;加詞尾-s時,其后介詞 of不能省略。如:several dozen (of) pencils=several dozens of pencilsAMILY: 'Times New Roman'">several dozen (of) pencils=several dozen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,或其后的接的是us, them這樣的人稱代詞時,則此時必須用介詞 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。
