Today is Sunday, I have been studying all day long. On the morning, I had a dry breakfast. We have no water to drink because the water supply had cut off. The water came back in the evening. I did math then. I didn't stop after 12 o'clock. After a short lunch I had the break. Then I went to my Sunday English Class. After a long and tired class for more than two hours, I got to home. Some work had been done but some hadn't. I must review all my subject such as the Sciences, the Humanities, which includes Chinese, English, Politics and History as well. That's terribly! Especially when there was no water.
