请帮忙写下文章大意.不过是要演讲稿.应付课堂
Recent efforts toward the greening of our cities have achieved much,although the results are still far from satisfactory.In recent years many trees have been planted in the cities and much care has been taken of the planted trees.In spite of all this,the greening process is relatively slow compared with cities in many other countries.For example,the green space available on average to each Shanghai citizen is only 0.4 Mu while every Londoner has more than 20 Mu.
We can benefit much from making our cities greener by planting trees.First,trees absorb carbon dioxide to produce oxygen which is essential to the health of human beings.Second,trees and other greenery make our cities more beautiful.Third,trees can also improve the climate of the cities.
Since we can get so much from making our cities greener,we should spare no effort to do that.We should plant more trees and take better care of them.We also should not cut down the trees.In a word,we should do everything to add to the greening of our cities.

Answer 1

这是说绿化问题的.
尽管现在我们很注重绿化了,但是还是比不上许多国家.
绿化使我们受益匪浅,因为绿化技能吸收二氧化碳,放出氧气,其次能使城市变得更加漂亮,最后还能使气候变得适宜.
还有是鼓励我们多植树,少砍树
