2.Teens are gaining(增加)weight.Today most teenagers are at least one size larger than teens were 20 years ago.Even clothing sizes have changed.Did you know that a small today used to be a medium,20 years ago?
   A recent research shows 97% of teens need more exercise.It's bad news because too little exercise means you are missing a lot of good things in life.Exercise helps in two ways.
   First,exercise helps your body.Physical activity can make your body strong.It can also keep you at a healthy weight.Doctors say that people who stay at a healthy weight have fewer health problems.Second,exercise can help your mind.People who get plenty of physical activity might worry less and sleep better at night.You may even learn better in school.Students who are healthy can listen and understand better in class.
   You can change your life and be more active at any point.It's never too late.An article called"How to Limit Screen Time and Get Moving"gives these ideas:
Step away from the screen.Doctors call watching TV or playing video games screen time.You should have no more than two hours of screen time a day.You will enjoy life more if you live it instead of watching it!
  Start slowly.An hour a day can seem like a long time.Start with 10 minutes of new activities every day.Add more as you get stronger.Think about walking.Take the stairs instead of the lift.You will feel healthier.
   Make fitness fun.Find a sport you like.It doesn't need to be the traditional sports of basketball,soccer,or baseball.Those are all great sports and if you like them,play them.However,you can also try hiking,skateboarding,or even rope jumping.If you enjoy the sport,you will do it.
   Choose food carefully.Help your family shop for healthy food.Read the labels(标签),look for healthy foods.Eat lots of fiuits and vegetables.Stop buying soft drinks and junk foods.You will feel better if you eat right.
   Exercise with others.Find a friend or family member to exercise or play with you.You will have more fun and it helps keep you responsible for going.

6.With more and more cars on the road,the traffic jam will happen.How do we see it and how can we solve the problem?
  We know that the traffic jam happens in many places,especially in big cities.What are reasons for the problem?On one hand,some people think that they should have a car when they have enough money,and then it's easy to go out and they can feel comfortable.On the other hand,a growing number of people hope to use their cars to show off(炫耀).What's more,years of research has shown that one of other reasons for the traffic jam is the driving habit.For example,many young people enjoy driving very fast,so they can feel excited.At last,most of them hardly care about the speed(速度)rules.
   Many governments are working at how to make the traffic better.In my opinion,firstly,the governments should educate those people who have cars or plan to buy cars.The governments must make them know that the traffic jam is very serious,and set up a much more perfect traffic system(体系)to solve the traffic pressure.
