【简答题】
B Sun Liping, 6 , lives in a small village in Yunnan. Her biggest wish is to have running water in her home. All 35 families in Sun’s village have a serious problem--- they don’t have enough water. Every day, the villagers have to walk 20 minutes to get water. Last year, the worst drought since the 1950s hit Yunnan, making more than 2 million people short of drinking water. This year, the drought is even worse. Not only Yunnan, but many other provinces in China are short of water as well, such as Gansu and Qinghai. According to a report on February 17, each Chinese person has about 28% of the world’s average(平均的) person’s amount of available(可用的) water. Two thirds of China’s cities are short of water and nearly 300 million people in rural areas don’t have safe water for drinking. Every drop of water is important. Waste a drop of water a day and you lose a bucket(桶) a year. How can we use water in a smart way? Here are some tips for you to save water in your daily life: 1. Put plastic bottles of water in your toilet to cut down the water waste when you flush (冲洗) your toilet. 2. Don’t keep the water running while you’re brushing your teeth or washing your face and hands. 3. Use low-flow(低流量) shower heads . 4. Use a bucket to collect shower water while you wait for it to warm up. 5. Make your shower time shorter. 6. Set up a rain bucket to collect rainwater for watering plants or flowers. 小题1: What is the problem in Sun’s village? A.They don’t have enough food. B.They don’t have enough water.
