Trouble: now I have a trouble is the free writing because I really don't know what should i write about. Ok, accturly I think i really have some troubles right now.This is the fitst time to take the CS1 class. It's harder than i imagain. Due to the teacher's speaking speed is faster and the vocabulary they use is advanced than the 50 class I used taken. So I feel a little hard to follow them. Another problem is the home work, it's more than last quarter and it make me sleep late every night. I feel so presser and I don't know what should i do. Maybe i should keep on trying and my writing speed should catch up the home work. I know the only way to improve my writing ablity is prectice and prectice. But it's still a hard work for me to write so many things everyday. what luck is reasently I changed a compsition class, and in the new class, there not so much home work as before.

Many kinds of entertainments in night will make a loud noise. For instance, the dancing and the gambling. For those people who join in the game they may enjoy it. But for others, it's really noisiness. The last reason is all transportation. Like cars and trains they made lots of noise. especially the plane. In a airport, the noise can be hundreds dB.
