一般认为把字句宾语必须有定。本文却认为把字句的宾语是否有定并非关键,更重要的是看宾语的属性明确性与句子语境要求之间能否互相匹配。如果不匹配,把字句的宾语可能产生属性不够明确或者过于明确的错误。如果匹配,宾语有定、无定都可成立。本文对这种新认识到的匹配机制的原理进行了探讨。 It is generally believed that the sentence object must be defined. This article thinks that it is not the key to determine whether the object of the sentence is definite or not. What is more important is to see whether the clarity of the property of the object and the requirement of the sentence context match each other. If they do not match, the object of the sentence may produce a property that is not clear enough or too clear. If you match, there is a fixed object, no fixed can be established. This article explores the principle of this newly recognized matching mechanism.
