摘要
在肯定性陈述结构中,一般主语位置上的施事成为对比焦点且受“是”标记是有一些限制条件的。如果焦点标记词“是”与范围副词“都/就”都针对某个施事,则“是”与“都/就”只能分现,不能同现,因为一个施事只能允许被凸显或强调“量性”和“施者”这两个信息成分中的一个。对比焦点标记词“是”与“连”在同一句子里不能共现,其原因在于违背了“单一强式焦点原则”。在变式句中,一般主语位置上的施事(话题)都不能接受“是”的标记而成为对比焦点,因为话题与焦点在本质上是对立的。
There are some restrictive conditions when an agent as subject becomes a contrastive focus and is marked by ＂shi＂ （是） in positive declaratives. The focus marker ＂shi＂ （是） and the scope adverb ＂dou＂（是） can only be or ＂jiu＂ （ 是 ） can not co-occur if they both aim at an agent simultaneously, highlighted either as the quantity or the actor. The contrastive focus marker because an agent ＂shi＂ （ 是 ） and ＂lian＂ （连） cant co-occur in the same sentence, because it violates the ＂single strong focus principle＂. An agent （ topic） as subject can not become a contrastive focus or be marked by ＂shi＂ （是） in a normal sentence, for the topic and the focus conflict with each other.
