这种应该怎样回复老师呀？

You are encouraged to apply for our PhD program at XXX. You have pretty good GPA and I believe there should be no problem to get our admission. Our department typically gives Teaching Assistantship (TA) to 1st year PhD students, and after that professors can continue to support as RA.
Please keep me informed about your application status later.

这是个模板回复还是比较积极的回复呀？求问有经验的同学们应该怎么回信比较好呀？
