Thanks 珈玥 ！When one's English grows, when one understands jokes,

movies, and novels one will know he is grasping and geting hold of the new langauge.If one  used to live in poverty and didn't get the same educational opportunities as other people his age, when facing the stiff competition he would not have a chance to get a good job. Besides studying hard, I could not find any better way to pull myself out of  bottom of poverty and getting lost. Thank you for your constant encourgement!
