【正确答案】[范文] The Changes of Urban Green Coverage Ratio
①
As is shown in the graph, the green coverage ratio of a city is continuously rising from 44.4% in 2013 to 46.8% in 2016. ②
This phenomenon implies that the city government is paying increasing attention to the green coverage ratio.
③
I believe the changes are caused by the following reasons. ④
Firstly, environment deterioration in cities is a great threat to people's health, so we have to increase green coverage ratio in urban areas. ⑤
Secondly, more modern buildings and infrastructures in cities leave a little space for many other species. Thus, making green lands shows human being's care for other species. ⑥
Third, green space embodies the harmony between human beings and the nature. The past economic development makes us realize that the quality of people's life depends on how we treat the nature.
⑦
The changes of urban green coverage ratio suggest that nature becomes increasingly important in modern society. It is certain that green open space will make a city suitable for living.
