用法:
1. 與具體數字連用時,不加複數詞尾 –s;若後接名詞,通常也無需用介詞of。如:
He bought three dozen bottles of wine.他買了36瓶酒。
He has lived here for two score years. 他已在這兒住了40年。
2.偶爾也可見到受具體數字修飾的dozen, score後接 of,但慣用法認為省略 of則常見。
3. dozen可用作量詞, a dozen of修飾名詞時of可省略,但dozens of中的of不能省去。
There were dozens of people there. 那裏有許多人。
I have heard of that scores of times. 那件事我已聽過很多遍了。
4. 當與a few, several, many等數目不很具體的詞連用時,帶不帶複數詞尾 -s均可,但是注意:若不帶複數詞-s,其後的`介詞of可以省略;若帶複數詞尾-s,則其後介詞of不能省略。
several dozen(s) of eggs=several dozen eggs 幾打雞蛋
several dozen (of) pencils= several dozens of pencils 幾打鉛筆
5. 若其後的名詞受the, these, those等特指限定詞的修飾,或其後接的是us, them 這樣的人稱代詞時,則此時必須用介詞of。如:
I had bred a dozen of chickens.
我飼養了12只小雞。
There were about a dozen of them.
大約有十二人。
6.用作形容詞,表示一打的,十二個的。
My mother bought a dozen eggs.
我媽媽買了一打雞蛋。
They began by baking two dozen loaves.
他們通過烘烤兩打的麪包開始。
