关于代词it和that用法的一道选择题
it，单数，特指，相当于“the + 单数/不可数名词”；与所指代名词属同一类，而且是同一个。
This is my watch; it’s a Swiss one. (《牛津现代高级英汉双解辞典》)。
Where is my book？Have you seen it？(同上)
以上两句中的it均特指前面所指代名词，和前面所指代名词同类而且是同一个。
that的用法
that, 特指，单数，相当于“the + 单数/不可数名词”，与所指代名词同类，但不同一，具体指哪个取决于其后定语of-短语。例如：
My seat was next to _______ of the teacher.
A. one B. it C. that D. seat
空白处需一代词代替其前可数名词seat,以避免重复。因有后置定语of the teacher, 故所需代词为特指，且与所指代名词同类不同一（老师的座位），故排除A、B、D，答案为C (that)。又如：
Nine in ten parents said there were significant differences in their approach to educating their children compared with _______ of their parents.
A. those B. one C. both D. that
空白处需一代词代前面名词approach, 单数，故排除A、C。因有后置定语of their parents, 特指，故排除B。答案为D (that)。
三词的区别主要从以下方面入手：1，代替可数或不可数名词；2，泛指或特指;3,修饰语（定语）前置或后置；4，代替人或物。巧记法如下：
可数单数用one替，ones替代复数词。
不定冠词后加one，one前一般有定语。
替代若系本身物，it 替单 they 代复。
比较句中替代词，不可数名词that替。
最高级及序数词后，替代词常常被略去。
复数名词替代词，ones 与 those 均用之，
特指 ones 加定冠，those 之前无冠词。
One(s) 的定语多在前，those 的定语必后置。。
