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.

NEW PRODUCT WILL SAVE LIVES

Drinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr Adrian Parton, who started Genera five years ago. He and his employees have developed the test together with a British water company.

Andy Headland, Genera's marketing director, recently presented the test at a conference in the USA and forecasts good American sales for it. Genera has already sold 11 of its tests at ~42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.

Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr Headland believes the company should make around 1.9 million by the end of the year in the UK alone.
