too...to中too后能加adv么

可以 too ..to是因．．．．而不能...
too后面可以加adj. or adv.
to 后面可以加do sth.
我们刚学 希望能帮到你！

可以吧，只要前面有ADV修饰的动词就行。例：

He started too early for me to catch up.
You were talking too loudly to hear others.

可以.

He smokes too severely to be cured.

不能的~TOO就是ADV了~~应是加ADJ

可以的
"he walks too fast for us to catch"

可以
