According to the passage, the reason for big cities to build their own recycling plants is that ______.
A.they can be of great help to the protection of environment
B.it is more expensive to process wastes in a farther dump
C.they can make the wastes into something that is useful
D.they can produce a lot of energy for the local residents
参考答案
正确答案:B
