What Can We Benefit From Riding Bicycles?

Speaking of bicycle, some people think ithas outdated in many big cities. However, some people think that it is stillpopular for them because people can exercise themselves by riding bicycle. Forme, I think people can get lots of benefits from riding bicycles.
说起自行车，很多人认为在很多的大城市，它已经过时了。但是，一些人认为自行车并不过时，他们可以通过骑自行车来锻炼身体。就我看来，我认为骑自行车有很多好处。

First, we can become healthier by ridingbicycles. Since people are busy with works, they have almost no time to doexercise. But if they ride bike to work, then they can practice themselvesquite often. Consequently, they will be healthier.
第一，骑自行车可以让我们更健康。很多人忙于工作，没有时间去锻炼自己。但是如果他们骑自行车上班的话，那么他们可以经常锻炼自己。因此也会变得更加健康。

Secondly, bicycle is good for ourenvironment. In almost all big cities, the average temperature is a bit higherthan countryside for there are too many car emissions there. We all know thatpeople in big cities like to drive cars to go to work rather than taking publictransportations. Therefore, our environment is polluted by lots of emissions.If more people join in the trend to ride bicycles to work, then our air qualitywill be improved obviously.
第二，自行车很环保。在几乎所有的大城市里，平均气温要比乡村高，因为城市里有大量的尾气排放到空气中。我们知道，很多在大城市里工作的人都喜欢开车上班，而不是乘公共交通工具。因此，空气会被大量的汽车尾气污染。如果更多的人参与到骑单车去上班的大军中来，那么我们的空气质量也会有显著改善。

In conclusion, riding bicycle not only can makeus healthier but also it is good for protecting ourenvironment. So, we should encourage more people to ride bicyclesquite often than driving cars.
总之，骑自行车不仅能让我们更加健康，而且也有利于环境保护。我们应该鼓励更多的人来骑单车，而不是开车。
