Why is Chinese claimed a language with implicit grammar?
【正确答案】：It is claimed that Chinese is a language with implicit grammar because it has gone through the stage of explicit grammar, whose supporting evidence is that English has been losing explicit grammatical morphemes and becoming more and more similar, though not identical, to Chinese, as far as grammatical structures are concerned.
