Death Valley is the hottest and the driest place in North America. Yet Death Valley is full of life. Death Valley isn’t an easy place to live. It gets less than two inches of rain a year, so there isn’t much water. It’s hot too. In July, temperatures often rise to over 46°C. The ground is mostly sand and rocks. There is even a dried-up lake that has turned into salt crystals (结晶). Although the weather conditions in Death Valley is terrible, it is still filled with lives.Nothing can stop plants and animals from making it their home. People have found more than 1,000 types of plants there. It also has 51 types of mammals (哺乳动物), 36 kinds of reptiles (爬行动物), 6 types of fish, and more than 300 kinds of birds. The animals aren’t all small, either. There are big ones like bighorn sheep, mountain lions,and mule deer. Water is the biggest challenge for anything that lives in Death Valley.

The best time to see snow and ski is from November to March. The Changbai Mountains are home to lots of animals as well. Chinese mergansers (中华秋沙鸭) are among them.

D．The Challenge of Living in Death Valley 【答案】【小题 1】D【小题 2】D【小题 3】B【小题 4】A【小题 5】A 【导语】本文是一篇说明文，介绍了北美最炎热、最干燥的死亡谷，虽然环境极端恶劣，但依然生存着大量动植物，展现了顽强的生命力量。 【小题 1】第二段提到 “It gets less than two inches of rain a year”，明确说明死亡谷每年的降雨量不到两英寸，对应选项 D。 【小题 2】第二段明确提到 “The ground is mostly sand and rocks”，因此 D 项表述正确；A 项与第一段 “Yet Death Valley is full of life” 矛盾；B 项与 “the hottest and the driest” 矛盾；文中只说七月很热，并未说全年都热，C 项错误。 【小题 3】第三段开头 “Although the weather conditions in Death Valley is terrible, it is still filled with lives.”，整段都在讲死亡谷的生物，因此it 指代 Death Valley。 【小题 4】第三段使用了1,000 types of plants、51 types of mammals、36 kinds of reptiles等大量数字，作者是通过列举数字来支撑观点的。 【小题 5】文章重点介绍死亡谷虽然环境恶劣，但依然充满生命，因此最佳标题是Life in Death Valley。 三、阅读还原。阅读短文，从所列选项中，选出最佳选项填入对应空白处，使短文通顺、连贯。（选项中有一项多余） In Australia there is a famous island called Fraser Island.

B．The island is completely made of sand. C．People often take photos everywhere. D．Unluckily, visitors have caused many problems. E．Many kinds of birds and other animals live in the forest. F．So it is time to protect the environment of the island. 【答案】1.B 2.A 3.E 4.D 5.F 【导语】本文是一篇说明文，介绍了澳大利亚弗雷泽岛的独特地理特征、自然风光以及游客带来的环境问题，并说明了当地采取的保护措施。 【小题 1】根据后句 “In fact, it is the largest sand island in the world.” 可知，前句应说明这个岛是由沙子构成的，B 项 “这个岛完全是由沙子构成的” 符合语境。 【小题 2】前句提到 “The long beach along the east coast works as the airport.”，东海岸的长滩充当机场，因此 A 项 “飞机从这里起降” 衔接自然。 【小题 3】前句介绍了岛上有森林、鲜花和湖泊，E 项 “森林里生活着许多鸟类和其他动物” 继续介绍岛上的生物，符合逻辑。 【小题 4】后文提到动物被捕杀、湖泊被污染，都是游客带来的问题，D 项 “不幸的是，游客造成了许多问题” 可作为本段主题句。 【小题 5】后文介绍了已经制定的规则，目的是保护环境，F 项 “所以是时候保护这个岛的环境了” 引出下文的保护措施。 思维创新 任务型阅读。 The famous Changbai Mountains lie in Northeast China.
