     "What would you do if you were the mayor (市长) of your city?" We asked some students from

different cities in Anhui. Here's what they said:

      Deng Chuan, 15, from Hefei

      With the development of modern industry, more and more waste water is being poured into the

Fei River, It has caused serious pollution. The river is becoming so dirty that few living things can live

in it. So, if I were the mayor, I would order all the factories that pour the waste water into the river to

close down. As we all know, water is very important to our lives. So it is very important to protect water.

      Zhang Yan, 14, from Wuhu

      Our city is more and more beautiful. But sometimes it's not convenient for the blind. There are not

enough pavements (人行道) in our city. Some of the old ones are broken. They may not be safe to walk

on! If I were the mayor of our city, I would build more pavements for the blind.

      Wang Lili, 16, from Chaohu

      There are more and more old people in our city. And there are not enough places for them to relax

and enjoy themselves. So, if I were the mayor, I would build an activity center in each residential (住宅)

area for the old. So old people can play cards or chess. This will make old people not feel lonely and spend

remaining years comfortably.
