Many things have been done and great progress has been made in the greenization of our cities in recent years. Many trees have been planted and much care has been taken of the planted trees. But, in spite of all this, greenization in the cities in China is far from satisfactory compared with cities in other countries in the world. For example, the green space for every people in Shanghai is only 2 square meters while that of the people in London exceeds 20 square meters.

　　许多事情已经做了很大的进步已经在我们的城市，近年来绿色化了。许多树木被种植的照顾已采取植树。但是，尽管如此，在中国的城市绿化是远远不能令人满意，与世界上其他国家的城市相比。例如，在上海的每个人的绿色空间只有2平方米，而在伦敦的人超过20平方米。

　　We can benefit much from the greenization of our cities. First, trees absorb carbon dioxide which is harmful, but produce oxygen which is essential to human beings. Secondly, with trees all around, our cities will look more beautiful. Thirdly, trees can improve the climate of the cities, making it neither too hot in summer nor too cold in winter.

　　我们可以从我们的城市绿化中受益很多。首先，树木吸收有害的二氧化碳，但产生的氧气是人类生存的基本要素。其次，四周的树木，我们的城市看起来更漂亮。第三，树木可以改善城市气候，使得它既不太热，冬天不太冷夏天。

　　Since we can get so much benefit from making our cities greener, we should spare no effort to do so. We should plant even more trees and take even better care of them while they are growing. Besides, we should not cut down trees any more. In a word, we should do everything to add to the greenization of our cities.

　　既然我们可以从城市绿化中得到这么多好处，我们应该不遗余力地这样做。我们应该种更多的树和更好地照顾他们，而他们正在成长。此外，我们不应该砍树。总之，我们应该尽一切努力增加绿化我们的城市。
