There are lots of things to do in our lives. Some people don't know what to do while others have succeeded. We always ask parents to tell us it is time to do sth when we study in primary school. After school parents tell us we must do our homework and we must go to bed at night. End-term exam is coming, and it is time for us to revise our lessons. And we must reviese lessons carefully fo End-term examination.
