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.
近年来我们的城市绿化的很多工作已经完成，并取得了很大的进步。种了许多树，种树方面也引起很多关注。但是，尽管如此，中国的城市绿色跟世界上其他国家的城市相比，却远远不足以令人满意。例如，在上海人均绿化空间只有2平方米，而在伦敦的人们超过了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.
我们可以从城市绿化中受益很多。首先，树木能吸收有害的二氧化碳，但也会产生对人类至关重要的氧气。其次，周围布满树木，我们的城市看起来会更美丽。第三，树木可以改善城市的气候，使其夏天不会太热而冬天不会太冷。
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.
因为我们可以从城市绿化中得到很多好处，我们应该不遗余力地这样做。我们应该种植更多的树木，并在它们生长时更好的照顾它们。此外，我们不应该再砍伐树木了。总之，我们应该尽一切努力加入我们的城市绿化中。
