21. In some countries, teenagers have jobs while they are still students. Do you think this is a good idea? Support your opinion by using specific reasons and details.

Nowadays, many students have their jobs while they study. They are usually waiters in  fast-food shops, tutors, to list just a few.  In this essay,.  I will argue that having part-time jobs is not good to students

Many students find jobs in order to earn their pocket money . In  fact, it is unnecessary . As they spend  a large  amount of   money to buy many brand name clothes, their idol¡¦s collections and the like .Therefore, they need to take  a job Indeed, it  is not essential to them.  Moreover, they always work after school until 11p.m. at night. They even work at  the weekend too.

As they always have to work, they don¡¦t have any energy to attend their lessons. In addition, they can¡¦t concentrate in class and they fall asleep easily . What¡¦s more, they will fall asleep during the lesson and they can¡¦t listen to what the teachers has taught in the lesson. Therefore,  it will affect their academic results. As they have to work part-time, they won¡¦t have  time to study and do their homework. They do not have  time to review their work.  Some of them even study in the mid-night.  I think it is of no use as they can¡¦t pay attention to  their study because they will feel very sleepy and tired. In addition, it will affect their health as they always do not have  enough sleep and always feel tired.

By and large, I think students should not have any job while they  are studying. If they do not have enough pocket money, they can ask their parents. If their parents do not give them  more pocket money, students should not spend  much money. Moreover, they should not waste money to buy brand-name clothes or  idol¡¦s collection too. Furthermore, students have many chances to work in  future, therefore, they should pay more attention and try their best to  study. I hope all students will concentrate on their study and do not find any job while they are studying.
