诗词曲这三种文学体裁在修辞上的特点之一就是爱用对偶。究其原因,大概是客观事物具有成双成对的自然美,人们的心理偏又喜欢这种对衬美,而据此用入诗词曲中则就增进了它们的音乐美,便于朗朗上口。 对偶也叫俪辞,在近体诗中叫对仗,独立出来作为一种文学样式就叫对联或对子。可以说,对偶包含了对仗与对联。 One of the three rhetoric features of these three genres of poetry and song is the love and use of duality. The reason is probably that objective things have a natural beauty of pairing and pairing. People’s psychological biases like this kind of lining the beauty. Using them in poetry and song thus enhances their musical beauty and makes it easy to catch up. Duality is also called chanting. In modern style poetry, it is called confrontation. As a literary style, it is called a couplet or pair. It can be said that duality includes confrontation and couplet.
