在下美籍华人,很荣幸为您修改.
I am so glad to hear the news that I've passed the test. Thank you very much for your concern.(Thanks a lot一般要单独用,如果是按你的方法,在北美,一般都是讽刺别人的时候才会用.)
I will continue to learn engineering knowledge for my future works.
I will also continue to do my current job, until I officially transfer to Sustaining Engineer jobs.
In addition, I will actively cooperate with our leaders’ training program. Try to make greater achievements in the new position.
其他的一些小错误直接替您改正了,希望可以帮到您~
