哪一种比较好？一般要具备怎样的条件
參考答案:offer是提供奖学金，一般包括
1、 tuition waiver 免学费
2、 stipend 月津贴(有些地方也叫工资)
stipend有三种 A RA 研究助理
B TA 助教
C FELLOWSHIP
前两者是要干活才能拿的,属于工资类型, 一般学校的PHD都有, 但FELLOWSHIP很少, 除非你真的背景很强, 因为FELLOWSHIP是不用干活的, 是完全的奖学金.
TA全称是teaching assistant，即辅助教学，一般就是帮助教授给本科班次的学生上课或者批改作业，必须通过tse的测试。
fellowship is a kind of scholarship providing a monthly stipend for the receipient. Some times TA is part of the fellowship package. This way the overall income each month contains a stipend (directly from the scholarship) and a salary (depending on how much you work for the TA)
Stipend is tax-free while the money you get from TA is taxable.有些地方Fellowship相当于RA 还是要干活的
