1.one替代由可数名词所表示的一类人或事物中的任何一个,即泛指中的强调.这时,替代词one前面不可加任何限定词.例如: 1)I hope there are enough glasses for each guest to have one.(NMET'95) 2.one用来替代特指的同一类人或事物的可数名词时,其前面必须加上限定词(如a,the, this, that等)、物主代词或形容词加以修饰.例如: 1)If you don't like this blue coat, you can buy a black one. 3.one在定语从句中作先行词替代特指的同一类人或事物时,其前面必须用定冠词the限定,但不可用that替换.如果先行词为"one of...",其关系代词在定语从句中作主语,从句中的谓语动词常用复数形式.例如: 1)This farm is the one that we visited last summer.(句中the one代替this farm,作先行 词,不可用that替代) 4.one的复数形式为ones,作替代词时,只可替代同一类人或事物的复数名词,其前面必须有限定词,如the, some, all等修饰.但不能用数词或many修饰.例如: 1)Mr. Zhang gave the textbooks to the pupils except the ones who had already taken them.
