Many people think that student have an easy life

3/. Many people think that student have an easy life:we only work a few hours a day and have long vacations. they don't know we have to work hard at school and at home.
          take a look at a typical grade 7 student like Hoa. She has five periods a day, six days a week. That is about 20 hours a week-fewer hours than any worker. but that is not all. Hoa is a keen student and studies hard. She has about 12 hours of homework every week. She also has to review her work before tests. This makes her working week about 45 hours. This is mỏe than some workers. Students like Hoa are definitely not lazy!
