老师这样的回复是什么意思？

第一封邮件
Yes, I will be happy to be your advisor and hope you will choose GT over your other offers.
I can commit to fund you for at least a year, and needless to say, even if only one of my pending research proposals pans out, I will be able to fund you till your graduation.

第二封邮件
Would like to add that I may be able to commit to a longer term of funding, if our department chair does not obligate me to fund all incoming CS students whom I have advocated for.

这两封邮件是连着发的，第一封邮件好理解，第二封啥意思呢。students whom I have advocated for是指他招的学生吗，招了学生还可以不funding？我如果想争取下长期的offer应该怎么回复比较好？

我觉得第二封是说 如果除非系里给钱不要求他出，不然他可以保证给你钱时间长一点
总的来说，这个还是蛮积极的，LZ去了之后好好表现，后面拿到钱应该不难，说一下thank you就行啦
