[2026原创]Grasslands are large, open areas of land covered mainly with grass instead of trees. They are very important natural environments, where plants and animals live together. They cover about one-fourth of all the land on earth. In fact, the only continent that does not have any grasslands is Antarctica.
There are two main types. Temperate grasslands, like the prairies (大草原) of North America, are found in cooler places. Tropical grasslands, often called savannas, are located closer to the equator where it is warmer. To be healthy, grasslands need a climate with plenty of sunshine and some rain.
Many different kinds of animals make their homes in these places. On the American prairies, prairie dogs dig underground homes to escape the heat and other animals that hunt them. In Africa’s savanna, large animals like elephants, zebras, and lions must all share the limited water. South America’s grasslands are home to the rhea, the largest bird on the continent. Australian savannas are home to many marsupials, like kangaroos.
Today, however, many grasslands are in danger. They face serious problems because of human activities. Huge areas have been turned into farmland for growing crops or raising cattle. The growth of cities and climate change also damage these areas, sometimes causing long periods without rain. To protect them, scientists are working with ranchers (牧场主) to find better ways to use the land. They want to manage it in a way that keeps it healthy for many years. By working together, they can help stop the soil from being destroyed and save these very important natural places for the future.

阅读选择·语篇导读 本文介绍了草原的相关信息。
快速对答案 1—5 D D C C A
1. D 推理判断题。根据第一段的“In fact, the only continent that does not have any grasslands is Antarctica.”可推知，南极洲的环境不适合草生长。故选D项。
2. D 推理判断题。根据第二段的“Temperate grasslands... are found in cooler places. Tropical grasslands... are located closer to the equator where it is warmer.”可知，温带草原位于较冷的地方，而热带草原位于较暖和的地方。因此，它们之间的主要区别在于所在区域的平均温度。故选D项。
3. C 推理判断题。第三段分别列举了不同大洲的草原上的动物，作者用具体例子来证明草原遍布世界各地。故选C项。
4. C 词义猜测题。根据最后一段的“Today, however, many grasslands... To protect them, scientists are working with ranchers to find better ways to use the land.”可知，them指代的是科学家们正在努力保护的草原。故选C项。
5. A 推理判断题。文章介绍了草原的定义、类型、分布、动物以及面临的威胁和保护措施。因此，作者的主要目的是向读者介绍草原。故选A项。

解析
【分析】
首先通读全文，明确文章围绕草原展开，介绍了草原的定义、类型、分布、栖息动物、面临的威胁及保护措施。解答每道题时，需回到原文定位对应信息，结合题干要求分析选项：第1题定位第一段关于南极洲的描述；第2题定位第二段两种草原的分布温度差异；第3题定位第三段列举的不同大洲草原动物的例子；第4题定位最后一段代词所在句的上下文；第5题梳理全文内容判断作者写作目的。
【解析】
1. 第1题：根据第一段最后一句“In fact, the only continent that does not have any grasslands is Antarctica.”可知，南极洲没有草原，说明其环境不适合草生长，故选D。
2. 第2题：根据第二段“Temperate grasslands... are found in cooler places. Tropical grasslands... are located closer to the equator where it is warmer.”可知，温带草原位于较冷区域，热带草原位于较暖区域，二者主要差异是平均温度，故选D。
3. 第3题：第三段分别列举了北美、非洲、南美、澳洲草原的特有动物，以此证明草原分布在世界各地，故选C。
4. 第4题：最后一段提到“many grasslands are in danger”，后句“To protect them”中them指代前文提到的草原，故选C。
5. 第5题：文章依次介绍草原的定义、类型、动物、面临的威胁及保护措施，核心是向读者介绍草原相关信息，故选A。
