They found that frigate birds can sleep while they’re flying! These birds take two kinds of short sleep. The first is called Rapid Eye Movement (REM) sleep. It is the deepest period of sleep. In humans, REM sleep can last for many minutes. For flying birds, however, REM sleep lasts for only a few seconds. Even so, this period is still very important for their brain health. The other kind is “half sleep”. Frigate birds put only half of their brain to sleep, while the other half stays awake. Their eyes are always connected to the waking part. In other words, they sleep with their eyes open. Before reaching land, they spend less than three per cent of their time sleeping. However, not all migratory birds sleep this way. Alpine Swifts can keep flying for nearly 200 days with few signs of sleeping. The sleeping habits of birds are different from species to species. 根据短文内容，回答下列问题。 1. What did scientists find about frigate birds in 2016? 2. How long does REM sleep last for flying birds? 3. What does “half sleep” mean for frigate birds? 4. How much time do frigate birds spend sleeping before reaching land? 5. What can Alpine Swifts do during their long trips? （四）书面表达（15分） 假如你是李华，你所在的社区正在举办“生物多样性保护”主题宣传活动。请你根据以下提示，写一篇短文介绍一种你认为最神奇的动物或植物。 提示要点： 介绍这种动植物的名称和基本特征；它最神奇的地方是什么（至少2个方面）； 它在生态系统中的作用；我们应该如何保护它。 写作要求： 词数80左右；内容完整，语句通顺；正确使用形容词和副词的最高级； 学科网（北京）股份有限公司 $ 八上 英语学科Unit 4 Amazing Plants and Animals单元检测 答案 参考答案 一、夯实基础，步步为营 （一） 1. popular 2. heaviest 3. role 4. fastest 5. oldest 6. per 7. whale 8. tiny 9. scientists 10. lotus （二） 1. largest; heaviest 2. fastest 3. most useful 4. most ancient 5. most interesting 6. tallest 7. biggest 8. most beautiful （三） 1. is home to 2. play; role 3. up to 4.
