只有第一个正确噢~ 启发，vt。所以要接宾语。 ~A~~启发~~B~~~，B大多数情况下都是指人。A可以是指人也可以是指物。翻译为A启发了B。 ~B~~受到~~A~~启发，A,B同上。“受到”的作用，和英语的被动语态一样，也可以改为“被”。翻译为B受到A的启发，即A启发了B。 所以，上面两句是一个意思，只是前者主动句，后者被动句。

他启发他的学生 is correct. 他的学生受到他的启发 is okay too.

他启发他的学生 - this one is grammatically correct and can express the idea（but a little bit weird）. 他跟他的学生启发 - this one is totally wrong. --------------------------------------------------------------------------------- >using 启发 as a noun: 我从这本书中得到了启发. - I draw inspiration from this book. 这本书给了我一些启发. - This book gives me some inspiration. >using 启发 as verb 他的话启发了我. - His words inspired me. 老师要启发学生的思维. - Teachers should inspire the mind of the students 你们要启发学生的创造性 - You should inspire the creativity of the students. BTW, sentence one in your question is weird , or maybe stiff , coz we do not often use 'sb 启发 sb', we are using 'sb 启发 sb's something' or 'sth 启发了 sb' .

that's different.the first is right,and the second is wrong.

The first one is right~
