阅读限时练 一、阅读理解。 A （重庆期末） Zhangye Danxia National Geological Park (张掖丹霞国家地质公园), located in Gansu, China, is truly a natural wonder.

In some dry places, not having enough water makes daily life very hard. People there have trouble finding enough water and getting clean water to drink. One good way to solve this problem is to dig wells (井) . With the help of modern technology, wells can now be dug near people’s homes. Special machines dig deep into the ground to find fresh water. After finding the water, a pump is put in. Then people can easily get water from the well. Having wells nearby is great because people don’t need to walk far to get water, and the water they get is clean and safe to drink. Collecting rainwater is another useful way. It usually needs many people to work together to build water tanks. Some tanks are built on rooftops, and some are built at schools. These tanks collect and store rainwater. The stored rainwater can be used when there is no rain. At school, these rainwater collection systems are like good teaching tools. Students can learn how to save water and protect the environment by using them. Reusing water also helps a lot when there is not enough water. Water used for washing clothes or taking showers doesn’t have to be thrown away. Even the water used for washing dishes, which can’t be used for drinking or cooking, can be used again. It can be used to water plants and fruit trees. This helps keep the plants alive and saves water at the same time. 29. What is one advantage of having wells near people’s homes? _______________________________ 30. Why are rainwater collection systems useful at schools? _______________________________ 31. What kind of water can be reused to water plants and fruit trees? _______________________________ 32. Besides digging wells, collecting rainwater, and reusing water, what is one more simple idea you could try to save water? Write 30 words or more. _______________________________ 阅读限时练 一、阅读理解。 A （重庆期末） 【1~4题答案】 【答案】1. D 2. B 3. C 4.
