4、当one(s)代替特指名词时，它前面总有定冠词或其他限定词 。例如： This room and the one upstairs are being cleaned 。
这个房间和楼上的那个房间正在打扫 。5、one 只能代替可数名词，如果所代替的是特指的不可数名词，那就不能用“the one”，而应该用that 。
例如： The study of English is as important as that(=the study)of Chinese 。学习英语与学习汉语一样重要 。
6、one(s)通常不用在名词所有格和形容词性的物主代词之后 。例如： His books are kept downstairs, and his elder brother ' s are kept upstairs 。
他的书放在楼下，他哥哥的书放在楼上 。7、one(s)不用在own和both之后 。
例如： My dog is black, his is yellow 。我的狗是黑色的，他的狗是黄色的 。
