这个句子中用the one或that均可,但在指代可数名词的单数时,人们常用the one而较少使用that。又例如:
I'll take the seat next to the one (= that) by the window. 我就坐在窗口的那个座位旁边。《英语特殊表现法例解》
▲ the one只能指可数名词,而that既可以指可数名词也可以指不可数名词,但that只指事物,具有特指性质。此外,that之后一定要跟修饰语。例如:
The weather here is hotter than that in Guangzhou. 这里的天气比广州的热。(that指不可数名词,不能用the one替换。)
The laboratory in my school is larger than that in yours. 我们学校的实验室比你们学校的实验室大。(that指可数名词的单数,可以用the one替换。)
