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.
近年來我們的城市綠化的很多工作已經完成，並取得了很大的進步。種了許多樹，種樹方面也引起很多關注。但是，儘管如此，中國的城市綠色跟世界上其他國家的城市相比，卻遠遠不足以令人滿意。例如，在上海人均綠化空間只有2平方米，而在倫敦的人們超過了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.
我們可以從城市綠化中受益很多。首先，樹木能吸收有害的二氧化碳，但也會產生對人類至關重要的氧氣。其次，周圍布滿樹木，我們的城市看起來會更美麗。第三，樹木可以改善城市的氣候，使其夏天不會太熱而冬天不會太冷。
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.
因為我們可以從城市綠化中得到很多好處，我們應該不遺餘力地這樣做。我們應該種植更多的樹木，並在它們生長時更好的照顧它們。此外，我們不應該再砍伐樹木了。總之，我們應該盡一切努力加入我們的城市綠化中。
