So the illocutionary act is what Austin really driving at.

在这个意义上，言语行为理论实际上就是行事行为理论。

This brings up another difference between the illocutionary act and the perlocutionary act, i.e. one is related to the speaker's intention and the other not.

这是行事行为跟效行为的另一点不同，前话人的意图有关，而后此无关。

In this general theory then, which applies to all sentences, the original performatives are only a special type in which the illocutionary force is made explicit by the performative verb.

在这个概括性更强的理论适用于所有的句子。

The statement " to say is to do" means that when we utter certain utterances, we are actually using language to undertake actions such as " warning, promise, greeting, order, naming, etc." , that is, illocutionary force

“即做”是指当我们出某种话语时，实际上是在用语言进行“警告、承诺、问候、命令、点名等”等动作，即言外之力。
