初中四册所选的臧克家写的《闻一多先生的说和做》一文有这样的句子:“我们要准备象李先生一样,前脚跨出大门,后脚就不准备再跨进大门。”这句句子里的“前脚……出,后脚……进”的函义按照词面是难理解的。因为人是靠两只脚走路的,前脚出,后脚随之也出,即古之一“步”,反之,前脚进,后脚随之也进,断无前后脚南辕北辙,即“前脚出,后脚进”之理。 Zeng Kejia, selected by junior middle school four, wrote a sentence entitled “Mr. Wen Yiduo’s Talking and Doing,” in which he said: “We are going to prepare like Mr. Li, the front foot will go out the door and the rear foot will not be ready to cross the door again.” Sentence sentence “forefoot ... ... out of the hind foot into the” meaning of the letter in accordance with the words is difficult to understand.
