【正确答案】　　I don’t think people are very aware of the problems concerning water. Many people don’t know that many cities, especially the big cities are suffering from a water shortage, especially during summer. Big cities have a large population and water consumption is enormous every day. Many cities have started charging households extra money per ton of water once their consumption has reached an amount. But I don’t think people attach much importance to saving water. In South Africa, a country that is facing a severe drought, the government even suggests people limit their showering within 90 seconds. If we don’t take actions now, this may be our future.
