Unhappy.

I am in shenyang China now.Today is not very happy ,and I do not know why the reason, Maybe because maybe because of the weather is extraordinarily cold wether today. And I feel longly lonely, so I want to go home , to be with my mother, my father ang and  all my families. What's worse, I will take a test called CET4. I am puzzled, because I don't know how to prepare for it. I am scared that I can't pass it. I amhave been nervous for many days. My classmates all study hardlyhard, but I don't like to study. I am so lazy , and I always want to play games .The weather is so bad that I don't want to go outside . I think I am a lazier lazybones.
