In fact, they are wrong. Most of the water is salt water. We can find it in the world’s oceans. Only about 3% is fresh water that we can drink. Although you might think that most of the fresh water on the earth is found in the lakes and rivers, in fact, less than 1% of the fresh water can be found in these places. Around 70% of the earth’s fresh water is ice in the polar (极地的) places. They are far from us. And the water there is tough to transport (运输). The second greatest source (资源) of fresh water on the earth is under the ground. This kind of water is called groundwater. Places that don’t have fresh water from rivers and lakes depend on groundwater for drinking and other uses. Groundwater also can’t get away from pollution. Chemicals (化学制品) that are used in farming and factories can get into the ground. The earth has little usable water. Luckily, each of us can do something to save water. Kids and adults are saving water wisely in their own communities (社区). If we work together, we will have a better world. 61. What percentage of the earth is covered by water? A. About 25%. B. About 75%. C. About 43%. D. About 85%. 62. What does the underlined word “tough” in Paragraph 2 mean? A. Dangerous B. Common. C. Difficult. D. Easy. 63. Which one can lead to the pollution to underground water according to the passage? A. Chemicals. B. Ice. C. Rubbish. D. Rain. 64. Which of the following is TRUE? A. People are not short of water. B. Most of the water in oceans is fresh water. C. We can find most of the fresh water in the rivers on the earth. D. About 70% of the earth’s fresh water is ice in the polar places. 65. The purpose (目的) of the passage is to ________. A. tell the situation of fresh water on the earth B. ask people to save water C. introduce different kinds of water on the earth D. talk about the pollution on the earth 第二节 阅读下面短文，从短文后所给的五个选项中选出能填入短文空白处的最佳选项，使短文通顺、连贯，意思完整。 (共5小题，每小题1分，共5分) E After a long, busy week, a relaxing weekend can be just what you need. ____66____ Here are some ideas for you.
