Some antonyms are gradable because there are often intermediate forms between the two members of a pair .

有些反义词存在级差，是因为在对词的两个词之间往往具有中间形式。

It is not advisable to tell beginners of linguistics that the distinction between gradable antonyms and complementary antonyms is relative .

对语言学初学者讲等级反义关系和互补反义关系之间的区分是相对的，这一做法不可取。
