       Everyone have annoyed, unhappy things and have not enough free time, I havn't excepton. I am from China, I attend chinese college entrance examination in june last year. As we all know, chinese college entrance examination is the most intense test. I am working hard everyday before I attend chinese entrance examination. I sleep time on more 6 hours everyday, usually I get up early at 5:45 am, up to 12:00 pm I can go to sleep and our total free time only have 30 days even more less on 365 days. So I often feel headache, but I can't leave. Because studying pressure is very huge and if I leave to rest, I won't catch else student learning speed.So I can't stop to study, I often feel headache. When I feel headache, I usually use my hand to knock my head or grovel in my desk, then I was feeling better.
