26/02/2009:I start to write a blog today because it can improve my english.Today ,after the lecture of statistic ,the lecturer told us that we will have a quiz next Tuesday.It's so stress to me since there are three quizes next week,now got 1 more quiz.hopefully, they are not too difficult to me.Initially,my friends and i were planning go to sing K this aternoon . Unfortunately,we canceled the meeting as my friends have class on 2p.m.
