:“而已”作为语气词表示限止 ,是由表陈述的“连词 +动词”结构演变来的 ,在其凝固成词的过程中 ,有一种两可的过渡状态。如果不细加辨析 ,“而已”往往导致误解 ,国内目前正在通用的两种《古代汉语》教材中的错误就是这样造成的。 The expression “only” as a modal expression means that it is evolved from the structure of “conjunctions + verbs” stated in the table. There is a two-way transitional state in the process of its formation. Without careful analysis, “only” often leads to misunderstanding. This is caused by the mistakes made in the two “ancient Chinese” textbooks that are currently being used domestically.
