【答案】Be a strong Chinese teenager       With the fast development of science and technology，China has become one of the most powerful countries in the world.A strong China needs strong teenagers，so it's our duty to improve ourselves.I think we have lots of things to do.
   First，we should learn to be honest and thankful.We are supposed to be friendly to others and behave politely in public.Second，we should take interest in our study and we must work hard.At the same time，we should have good study methods，such as listening carefully in class，going over what we have learnt in time.Third，it's helpful to be in good health.We'd better have enough healthy food instead of junk food.And we should spend at least an hour doing sports every day.Last but not least，we can spend our weekends doing some voluntary work at our community center or in the old People's Home.It's meaningful for us to do something for others.
   If we follow these，we will be strong enough to realize our dreams.
