2. My favorite sport is playing badminton. There are four reasons why I it. Firstly, I can improve my health through playing it. I play it about 2 times every week. It makes me feel energe everyday. Secondly, I enjoy the feeling that badminton flies in the air. I can change the movement direction of badminton without much effort and make opponent lose it. Thirdly, I can make many friends when I play badminton. I often play it with many kinds of persons. We can improve our skills with exercises. Also we talk about many interesting things when we have an break. Finally, playing badminton is not as intense as other sports such as basketball and soccer. It lessens the possibility of being hurt. So If you playing badminton, please feel free to contact me. I think we can exchange experiences and make friends.
3. I live in country so there aren't many busy road. However, one of the most difficult problems is dangerous road. In my hometown, you can see potholes easily. And special is every one walk in road normaly. There are many trucks move here make the road very bad. And there are many accidents . I hope that local government will repair them and everyone takes care about themWhen I was a student, I used to live in Hanoi.So I was the person who always got traffic jams. Nowadays, althought the traffic in Hanoi has been improved ,it still is one of the most serious problems in our society. In my opinion, there are some following ways to reduce the traffic jams. Firstly, The government should build more motorways because many streets and roads are narrow, a lot of transports share one road so it is easy to cause accidents and traffic jams. Secondly, a law about driving in city center should be given. Motorists driving in city center must be charged strictly. There are too much motocycles in the city, many motorisrs are too young, they don't have driving license, they don't understand the law or they don't obey the 
law seriously . The government should encourage people to use the puplic transport by discouring the price for someone who always uses public transport, especially for students ,workers, etc, opening more bus routes,maybe build the subway. I think subway is the best way to reduce the traffic jams. Things we should do immedietely are educating people from early age, issueing a law in traffic, banning stricly the person who don't obey the law. In conclusion, we should be aware of disadvantages of traffic jams. It affects on every sides of our life.
