在日语和汉语中一定情况下存在着同样的句意因采用不同句式而表达情态不同的现象。据此从认知角度出发,分析上述情况中采用主动态与被动态情态效果的不同,从论证举例中得出在何种情况下被动句式较主动句式在情态表达上更有优势。 Under certain circumstances in Japanese and Chinese, there is a phenomenon that the same sentence is expressed in different modalities due to different sentence patterns. Based on this, from the perspective of cognition, this paper analyzes the difference between the use of the main dynamic and the passive situation in the above situations. From the demonstration examples, it is concluded that the passive sentence is superior to the active sentence in the modal expression.
