During this long journey, when and how do they sleep? In 2016, some scientists studied a group of frigate birds（军舰鸟）during a ten-day flying journey. They found that frigate birds can sleep while they’re flying! According to this study, these birds take two kinds of short sleep. The first is called Rapid Eye Movement（REM, 快速动眼）sleep. It is the deepest period of sleep. For humans, REM sleep can continue for many minutes. For flying birds, however, REM sleep continues for only a few seconds（秒）. Even so, this period of sleep is still very important for their brain health. The other kind of short sleep is “half sleep”. Frigate birds put only half of their brain to sleep, while the other half stays awake. The eyes of these birds are always connected to the waking part of their brain. In other words, they sleep with their eyes open. It is still a little dangerous to take such a short sleep, though. So, these birds prefer to stay awake most of the time. Before reaching land, they spend less than three percent of their time sleeping. However, not all migratory birds sleep in this way. Many will make several stops on their way to get a good rest. Some stay completely awake for their whole journey. Alpine Swifts（高山雨燕）, for example, can keep flying for nearly 200 days. There are few signs of these birds sleeping during their long trips. The sleeping habits of birds are different from species（物种） to species. This makes the study of migratory birds very exciting for scientists. In the future, we may learn more amazing things about these animals! 根据短文内容，选择最佳答案

Washing your hands often also helps. However, people haven’t always known about germs. For many years, even doctors didn’t really understand how illnesses spread. ___17___ Some doctors even tried dressing like birds. In 1619, the French doctor, Charles de Lorme, invented a special uniform. He hoped it could protect doctors who were treating plague (瘟疫) patients. The uniform had a long coat, gloves, boots (靴子) and a hat. The doctors also carried sticks so they wouldn’t have to touch the patients. The most special part of the uniform was the mask (面具). ___18___ It had a beak (鸟嘴) that was about 15 cm long. There were also two eyeholes cowered in glass and two nostril (鼻孔) holes. At that time, doctors believed the plague was spread by bad air. Any air that had a bad smell was dangerous. ___19___ They believed this could stop them from breathing the bad air and they wouldn’t get sick because of the plague. Did it work? Well, not really. Certainly the germs sometimes traveled through the air, and the flowers weren’t able to stop them. ___20___ Some forms of plague only spread through certain animals such as mice. The doctors’ uniform helped to protect them from this danger. However, largely the coat, gloves, boots and hat did the job, not the bird mask. 根据短文内容，从下列选项中选出能填入文中空白处最佳选项。选项中有一项为多余选项。 The bird mask helped to protect the doctors from this danger.
