翻译为英语：我考研究生主要有以下几个原因

for me to take, 不过这句话怎么读都不通

there are several reasons for me to take the post grad exams.

没有错啊，for后面接动名词的~

是准备面试吧

用口语化的更好

There ara some reasons for me to take the post graduate exams

“my”没错，语法上没问题
“my taking exam of " exam前要加冠词‘the’

这样表达很怪，没见过样说的
不如用i take the graduate examination for the following reasons
