Speaking of bicycle, some people think it has outdated in many big cities. However, some people think that it is still popular for them because people can exercise themselves by riding bicycle. For me, I think people can get lots of benefits from riding bicycles.

說起腳踏車，很多人認為在很多的大城市，它已經過時了。但是，一些人認為腳踏車並不過時，他們可以透過騎腳踏車來鍛鍊身體。就我看來，我認為騎腳踏車有很多好處。

First, we can become healthier by riding bicycles. Since people are busy with works, they have almost no time to do exercise. But if they ride bike to work, then they can practice themselves quite often. Consequently, they will be healthier.

第一，騎腳踏車可以讓我們更健康。很多人忙於工作，沒有時間去鍛鍊自己。但是如果他們騎腳踏車上班的話，那麼他們可以經常鍛鍊自己。因此也會變得更加健康。

Secondly, bicycle is good for our environment. In almost all big cities, the average temperature is a bit higher than countryside for there are too many car emissions there. We all know that people in big cities like to drive cars to go to work rather than taking public transportations. Therefore, our environment is polluted by lots of emissions. If more people join in the trend to ride bicycles to work, then our air quality will be improved obviously.

第二，腳踏車很環保。在幾乎所有的大城市裡，平均氣溫要比鄉村高，因為城市裡有大量的尾氣排放到空氣中。我們知道，很多在大城市裡工作的人都喜歡開車上班，而不是乘公共交通工具。因此，空氣會被大量的汽車尾氣汙染。如果更多的人參與到騎單車去上班的大軍中來，那麼我們的空氣質量也會有顯著改善。

In conclusion, riding bicycle not only can make us healthier but also it is good for protecting our environment. So, we should encourage more people to ride bicycles quite often than driving cars.

總之，騎腳踏車不僅能讓我們更加健康，而且也有利於環境保護。我們應該鼓勵更多的人來騎單車，而不是開車。
