题目内容

听力原文: Because of the severe drought which has continued this year, water rationing will go into effect on Monday. Lawns can not be watered with automatic sprinklers; driveways, porches, and dicks can not be hosed down. You may water by hand, but only on even-numbered days. Cars can be washed on Wednesdays only. The city has hired a new drought patrol crew, which will be looking for offenders. If you are caught, there will be a $50 fine for the first offense and a $100 fine for the second offense. We realize that this is strict, but the drought has affected us dramatically. We ask your cooperation in conservation water. Besides the drought roles, we ask that you be prudent in your household water use. Turn off the faucet while you brush your teeth. Take short showers; you might even consider turning off the water as you soap up. Don't wash dishes under running water, and when you wash your clothes, save the final rinse water to begin your next load. Thank you for listening. Let's all work together to save our community's water.
