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(lái)越多的人都買(mǎi)得起汽車(chē)的。因此，道路往往沒(méi)有堆滿了汽車(chē)。然而，隨著越來(lái)越多的廢氣排放是汽車(chē)、空氣污染問(wèn)題變得更加嚴(yán)重。所以此刻我們提倡過(guò)低碳的生活。

　　我的推薦是我們就應(yīng)更經(jīng)常騎自行車(chē)而不是開(kāi)車(chē)騎一輛自行車(chē)，我們不僅僅能鍛煉身體，也能保護(hù)我們的環(huán)境。為什么不試試，我親愛(ài)的朋友?
