可是，请教NN, Even though 不是副词吗，怎么可以引导从句呢？百思不得其解，可能是我的语法盲点，恳请各位批评指导，谢谢！

我没听说过 even though不能连接句子。

even though
used to emphasize that something is true although something else has happened or is true
Even though he's 24 now, he's still like a little child. I can still remember, even though it was so long ago.

而且even though大多数情况下连接句子，想 even是adv. though是conj. even修饰though
