Modernization is necessary, sincewe can't go without it. Owing to the modernization, our life is improving dayby day.

現代化是必須的，因為我們不能沒有它。幸虧有了現代化，我們的生活可以日益改善。

In ancient days, people usuallyworked on the day and went to bed early at night. But as Tomas Edison inventedthe lights, we can do anything both on the day and at night. Moreover, thetransportation becomes much more convenient than before. Nowadays, we can goanywhere we like. And human beings can even travel in the universe.

在古代，人們通常在白天干嘛，晚上早早的就上床睡覺了。但因為托馬斯愛迪生發明了電燈，我們可以在白天或者晚上做任何事情。而且，交通變得比以前方便多了。現在，我們可以去任何我們喜歡的地方。人們甚至可以在宇宙中旅行。

However, every stick has twoends. Modernization also comes pollution. Now human beings always throw wasteinto our nature. That's why our earth becomes a dirty place.

然而，每個棒都有兩端。現代化也帶來了污染。現在，人類總是把廢棄物仍給大自然。這就是為什么我們的地球變成一個骯臟的地方的原因。

If we continue to pollute ourenvironment, our earth will be destroyed, so we have to do something to protectour environment. In the first place, we must form a good habit. Don't throwwaste everywhere. Second, we had better go to work by bus or by bike, so as toreduce the tail gas. Third, the waste gas and water must be done before theyare sent out. What's more, we should plant more trees and grasses to purify theair. At last, the government should make laws to prevent pollution.

如果我們繼續污染我們的環境，我們的地球將要被毀滅了，所以我們應該做些什么來保護我們的環境。首先，我們必須形成一個良好的習慣。不要隨處亂丟垃圾。第二，我們最好乘坐公共汽車或騎自行車去上班，以減少尾氣排放。第三，廢氣和廢水必須必須要先處理過再排放出去。更重要的是，我們應該種更多的樹和草來凈化空氣。最后，政府應該制定法律來防止污染。
