“一”原是数词,但它起的作用常常越出数词的范围。这里试就“一”在成语中的不同含义,列举如下: 表示“同”的意思。如:一模一样,一丘之貉,一概而论,言行一致。兼有“全”或“都”的意思。如:一生一世,一身是胆,一无是处,一年之计在于春。表示“专一”的意思。如:一心一意,一意孤行,一片冷心,一味贪多。 “One” was originally a numeral, but its function is often beyond the scope of the numeral. Here try “I” in the idiom of the different meanings, as follows: that “the same” means. Such as: exactly the same, a mound, in general, words and deeds consistent. Both “all” or “all” means. Such as: life and one, one is courage, nothing, one year plan is in spring. That “special” means. Such as: wholeheartedly, deliberately, a heartless, blindly greedy.
