We should Ride Bicycle More Often
Along with the level of income continuously improved, people use cars more than bicycles. But I think we should usually use bicycles. Riding bicycles won’t make pollution to the environment. Riding a bicycle is much quieter than driving a car. It does not make noise. And also riding a bicycle does not use oil, so it never sends out harmful gas. According to Dr. Smith’s investigation, Exhaust gas from cars contains much harmful gas. It can let us get disease. Riding bicycles is also good for our heath. We can use it to harden our body, in addition it can save our money. As well as riding bicycles can build our body and keep us fit. For instance, if you go to the health club for fitness, you will spend 30dollars for a mouth. Then if you by bicycle for half an hour you also can get the effectiveness of health. For these reasons, I recommend that you ride bicycle more often.
