虚词是相对于实词而言的,意义比较抽象,包括副词、介词、连词、助词、叹词和象声词。它们常常不能单独构成一个句子,但能够帮助造句,在人们的语言交际中主要表示比较抽象的并且与语法有关的意义,在语言中起着“经络”的作用。然而,虚词的意义比较抽象,同一个虚词又常常可以表示好几种语法意义,初学者往往很难准确地把握虚词的确切用法。鉴于虚词的这种特殊性,我认为虚词学习不能孤零零地单独地学习某一个虚词,而应该把它放在具体的句子中,用限定上下文的方法来综合比较,最后得出该虚词的具体用法及使用场合。 Function words are relative to the real words, the meaning is more abstract, including adverbs, prepositions, conjunctions, auxiliary words, interjection and onomatopoeia. They often can not form a single sentence, but can help make sentences, mainly in people’s language communication to express more abstract and syntax-related meaning, plays a “meridian” role in the language. However, the meaning of function words is rather abstract, and the same function word can often express several kinds of grammatical meanings. It is often difficult for beginners to accurately grasp the exact usage of function words. In view of this particularity of the function words, I think that the function words learning can not learn a certain function word alone, but should put it in a concrete sentence and use the method of limited context to synthesize and compare, finally draw the concrete usage of the function word And use the occasion.
