问题补充：

lots of trees and flowers planted everywhere, the city looks more beautiful.

A. As

B. For

C. With

D. Though

答案：

A. As

B. For

(答案→)C. With

D. Though

解析：考查with复合结构：句意：随着到处种了很多的树和花，这个城市看起来更加美丽了。注意这里的planted不是谓语，因为如果是谓语应该是are planted，所以这是过去分词，也就是不是一个简单句，而ABD三个选项都是连词，只有with复合结构是“with+宾语+过去分词”，选C。
