I have been having a good time these days.I have finished a very hard puzzle all by myself.Spending 20 hours on it,I have worked on it every day,and really enjoyed doing the work.I also have got involved into a volunteer activity,which lead the students who join it to different places to give a helping hand to people everywhere.I have enjoyed myself working and talking with my teammates,and it has been a great memory of mine.
就是初中及一下的水平.都是简单词,简单句子.
如有问题,欢迎继续追问：）
