One和that都可以作替代词替代前面的名词。但是one一般只能代替可数名词,that可以代替可数名词和不可数名词。因此,分清one和that作替代词的区别,对学生的英语学习有一定的意义。有时,为了避免重复前面的名词,可以用one和that来代替它,此时,one和that作替代词。 One and that can be used as substitutes to replace the preceding nouns. But one can only replace countable nouns, which can replace countable nouns and uncountable nouns. Therefore, to distinguish between one and that as a substitute for the difference between the students of English learning has some significance. Sometimes, in order to avoid repeating the preceding nouns, one and that can be used instead of it, in which case one and that are substitutes.
