这三个副词都是多义词,它们的部分意义很相似,有时还可替用。但即使是同义场合,相互之间语感上还有着微妙的区别,不是随便可以通用的。本稿就想说说这三个词的异同。为了便于说明,我们一反以往的作法,不先叙述各词的意义和用法,而是直接地从它们的同义部分着手分析,然后再扩大到非同义部分的意义和用法。 The three adverbs are polysemous, some of their meaning is very similar, and sometimes alternative. But even in the same place, there is a subtle difference in the sense of language, which can not be generalized. The manuscript wanted to talk about the similarities and differences between these three words. For the sake of explanation, we have gone back to past practices without first describing the meanings and usages of the words, but proceeding directly from their synonymous parts and then expanding to the meanings and usages of non-synonyms.
