adj.迂回曲折的；[语]迂说法的

Being a man true to my word, today we ll look at two such constructions, the ablative absolute and the passive periphrastic ; as well as the dative of agent. 身为言而有信之人，今天我要介绍独立从格和迂说被动这两种结构，以及施事予格（间接受格）的用法。

Most of the time, a periphrastic construction with a dative of agent will be very cumbersome to translate in to English. 大多数情况下，有施事予格的迂说结构要翻译成英文时会变得很累赘；

Finally, let s look at the Dative of agent today.Instead of the ablative of agent, with periphrastic constructions, the dative of agent is used. 最后我们来看施事予格（间接受格），在迂说结构中我们不用施事从格而使用予格。

Some common English expression used to translate a periphrastic construction are: Has to be, had to be, should, ought, must. 迂说只是一个简单概念所用的花俏名称，表示以迂迴方式说明某事的概念。

Most finite verbal forms diachronically derive from nominalizations and periphrastic constructions with auxiliary verbs. 副词，后置词几乎完全都有名词性的，形容词性的或动词性的起源。
