1 one 基本含義是“一個”,是數(shù)詞,但也可用作代詞,指代上文中剛提到過的單數(shù)名詞,可指人或物;如果指代的名詞是復數(shù),則用ones 。
2 the one 代替特指單數(shù)名詞, the ones 代替特指復數(shù)名詞。
3 one 前面常用定語修飾,如果是泛指,說a/ an+定語+one,如果是特指,說the+定語+one或the+定語+ones。另外,one 或ones 還可用this, these, that和those修飾。
This book is a good one . 這是一本好書。(one代替book )
These pens are good ones . 這些都是好鋼筆。(ones代替pens )
“Which pencil do you want?” “I want the blue one .” “你要哪一支鉛筆?”“我要那支藍的?!保╫ne代替pencil, the blue one表示特指 )
“Which books do you like best?” “The ones on the desk.” “你最喜歡哪些書?”“桌上的那些。”(ones代替books, the ones表示特指 )
“I'd like to buy some apples.” “Which ones ?” “Those big red ones .” “我想買些蘋果。”“哪種蘋果?”“那些又大又紅的?!保╫nes代替apples )
