“成分残缺或赘余”是辨析并修改病句这一知识点中六种病句类型之一,也是近几年高考命题考查的热点之一。在这一病句类型中,有一种命题方式需要我们警惕,即包含有成语的句子辨析。这样的句子实际上考查的是两个知识点,一是正确使用熟语(包括成语),二是辨析并修改病句。在这种情况下,句子里的成语很容易和句中的某些词语,尤其是相邻的词语形成语意的重复,因此,需要我们特别重视。 “Component or defective ” is one of the six types of ill-advised sentences in the knowledge point of discriminating and modifying the ill-posed sentences, and also one of the hot spots in examining the entrance examinations of the college entrance examination in recent years. In this type of ill-posed sentence, there is a proposition that requires our vigilance, that is, sentences that contain idioms. This sentence is actually examining two knowledge points, one is the proper use of idioms (including idioms), the second is to identify and modify the sentence. In this case, the idiom in the sentence can easily form a semantic duplication with some words in the sentence, especially the adjacent words. Therefore, we need to pay special attention to it.
