Dear Ms / Mr Wang,
I am XX. I am very glad to receive your reply and now I am preparing my papers for my graduation. By the end of the middle May, I will have been free after interview. I am too willing to study in your place in the summer vacation for I want to get familiar with your research group and adapt to it and then get on well with them. I will treasure this valuable opportunity you gave to me.
Thanks.
