“对”字句,是指用介词“对”或“对于”提示对象的句子。不少语法书已将它跟“把”字句、“被”字句一样看成有标志字的一种特殊句型。这种句型在汉语中产生很早,在先秦时就已有了,其代表字是“之於”。例如:天之於民厚矣。(《列子·论符》) The “right” sentence is a sentence that prompts the object with the preposition “right” or “right”. A lot of grammar books have regarded it as a special sentence pattern with marked words like the “把” sentence and the “被” sentence. This type of sentence produced very early in Chinese, in the pre-Qin period, its representative is “in.” For example: days of people thick carry on. (“Lie Zi Lun Fu”)
