替代词it, that, (the) one(s), those的用法it, that, one, those均可用来替代前面的名词，以避免重复，其用法如下：一、it和that都替代“the+单数名词(可数或不可数)”，都是特指，但it指前面提到的“同一”事物，而that是指前面提到的“同类”事物。如：1. The Parkers bought a new house but ________ will need a lot of work before they can move in. (全国卷)A. they B. it C. one D. which【分析】答案选B。it替代“the + house”，指的就是前面提到的the Parkers所买的那座新房子。2. Few pleasures can equal ________ of a cool drink on a hot day. (全国卷)A. some B. any C. that D. those【分析】答案选C。that替代the pleasure，指与前面提到的同属“快乐的事”。二、one替代“a＋单数可数名词”，表示泛指。特指的the one相当于that；the one复数形式the ones，在口语中也常用those代替；当后面有of短语时，一般用that或those，当有前置修饰语时，只能用one(s)，如the red one。one(s), the one(s), those, that都是替代“同类”事物，其中只有that可替代不可数名词。如：1.
