答案：How to be an excellent middle school student
As middle school students, it's our duty to be an excellent student. I think we have lots of things to do.
Firstly, we should develop good virtues. Being honest is very important. We should always tell the truth and never cheat in exams. Also, we need to be thankful. We should thank our parents for raising us, our teachers for teaching us, and our friends for helping us.
Secondly, we must work hard on our studies. We should listen carefully in class and finish our homework on time. It's necessary to have good study habits, such as making plans for our study and reviewing what we have learned regularly. By doing these, we can improve our grades and gain more knowledge.
Finally, health is the foundation of everything. We should have healthy food, like more fruits and vegetables, and less junk food. Doing sports every day is also essential. We can play basketball, run or swim to keep our bodies strong. Only when we are healthy can we study well and enjoy life.
In a word, to be an excellent middle school student, we need to balance virtues, study and health. Let's try our best to be better!
