所谓条件,就是前一事件还没有实现,而前一事件跟后一事件在逻辑关系上又呈现顺态接续的情况。在日语中,包含“ば.たら.と.たら”的条件句,又可以细分为假定条件,反事实条件,确定条件,事实条件四种类型。本文通过例句分析,阐述这四种类型的区别。 The so-called condition is that the previous incident has not yet been achieved, and the former incident and the latter incident have also shown a logical continuation of the situation. In Japanese, the conditional sentences that contain “” and “ta” can be subdivided into four types: hypothetical conditions, counterfactual conditions, definite conditions, and factual conditions. This article illustrates the differences between these four types through example sentence analysis.
