With the improvement of our living standard， more and more people can afford a car。 As a result，our roads are more often than not crammed with cars。
However，with more and more waste gas being discharged by the cars，the problem of air pollution bees even more serious。 So nowadays we advocate to lead a low-carbon life。
My suggestion is we should ride bikes more often instead of driving cars。By riding a bike， we can not only exercise our body but also protect our environment。
Why not have a try， my dear friends?
與我們的生活水平的提高，越來越多的人都買得起汽車的。因此，道路往往沒有堆滿了汽車。然而，隨著越來越多的廢氣排放是汽車、空氣汙染問題變得更加嚴重。所以此刻我們提倡過低碳的生活。
我的推薦是我們就應更經常騎自行車而不是開車騎一輛自行車，我們不僅僅能鍛鍊身體，也能保護我們的環境。為什麼不試試，我親愛的朋友?
