Not bad at all. Your pronunciation is fairly good, I had no problem understanding you. Here's what I transcribed:
Yes. First and foremost, I am major in English and it will benefit me a lot to study abroad.
Secondly I am now a graduate from the university and I am going to look for a job.
I plan to work for several years when I got enough money so I can support myself to go abroad to further my study.
Last but not least I think going abroad will broaden my horizon.
Its also, like, traveling I can live with others with the peoples in the other places.
A few grammatical corrections:
"I am a major in English", or "I am an English major", or (since you've graduated already) "I majored in English"
it will benefit me a lot: this is ok, but since the question was a conditional perhaps it's a bit better to say "it would benefit ..."
I plan to work for several years until I have enough money to support myself ...
... to further my studies (usually used in the plural in this context)
... broaden my horizons (again, usually plural in this context)
... I can live with other people in other places.
It's difficult to correct pronunciation in writing. As I said, pretty good. I would work on the pronunciation of:
I hope this helps.
