two days have passed  . i have found that i have a few setbacks in learning . i remembered there is a famous saying in TALMUD that if you do not increase your knowledge ,your will decrease it in reverse . even now i do find there is difficult for me to write down an article .i can not kown many words that i have met and learned before. what a pity .the one who can not make full use of time will be a loser . so at the very beginning of this semester , do well .and stick it with my friends .
