Wonderful, did you have a scipt when you deliver the speech? If you have, why do you have the same problem still? This is ur biggest problem now and this indeed sounds bad.  Another thing is ur stress, e.x. 'breakfast is not break'fast. You've done a good job except this two major problems on pronounciation.  另外一点请大家注意spirit和energy的区别. spirit意思是情绪，心情，你可以说I am in high spirits 我情绪高涨，energy意思是精力，干劲，能力。在wonderful的这篇文章中说道休息时间太短，导致没有精力上班，我觉得用energy可能好些，what do you think? Wonderful, congratulations for ur growning-up! Low payment, overworking may happen at the beginning, but you will pay effort to lead a better life by experiencing all of these! Next time, prepare a script for ur speech, at least prepare the guideline to make ur statement more smooth, ok?
