(21) How much can a professor earn?

　　As far as I know, many professors in Tsinghua University earn 10 thousand RM B per month。You know, the salary of professors is rising now。

　　(22) Why won’t you stay in the States?

　　It’s not my country。

　　(23) Can you explain why 90% Chinese students didn’t come back?

　　Really? If really so, I think everyone has its own reasons。But as far as I know, these years, more and more students have chosen to come back after graduation。As to me, I’ll definitely come back。I’ll take care of my parents, and I think it’s much easier to find an academic position in China than in the States。

　　(24) Can you promise that you will not be attracted?

　　Yes, and that’s sure。China is my motherland。
