3．Words in the Snow
　　In the time of the Yellow Emperor, there were no written words. People recorded things by tying knots (打结) in ropes and carving (雕刻) shapes on stone walls.
　　One day, the Yellow Emperor discussed an event with a wise man named Cang Jie. Cang took out a piece of knotted rope, but found it was rotten (腐烂的). It was impossible for him to remember the event clearly. Then he turned to a stone wall, but could hardly read the shapes on it. They had been carved by another person except himself.
　　"The ropes will be rotten. And the shapes can only be read by a few people," the emperor said to Cang. "Can you come up with something better?"
　　Cang thought over the matter for days and nights. On the morning after a heavy snowfall, the earth was completely white. He saw the footmarks of some different animals by accident. These footmarks helped him to recognize what animals had passed by. Cang suddenly had an idea. He picked a stick and drew on the snow-covered ground. He first drew a tiger and a bear to show that they had passed by. But soon, he found this was taking too much time. He realized that he had to make the drawings easier.
　　All the shapes on the stone walls flashed through his mind. Cang kept making all kinds of shapes on the ground easier. To show the sun, for example, he used a circle with a dot(小点)in the middle. A half﹣circle and a vertical line(竖线) made up the moon. And three curves(曲线) were used to show water. Later, the sun appeared. These simple marks shone brightly in the snow.
　　In the end, Cang created a whole set of symbols to record things. People could easily understand these symbols. Since then, they have been able to record their own history.

4．　　Migratory birds (候鸟) fly to different places during different seasons. They may fly day and night for months at a time. 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. In us 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!

5．The Bird Mask
　　Today, doctors know a lot about how to stop germs (病菌) from spreading. They suggest people cover their mouths when they cough. 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. (1)       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).
　　(2)       It had a beak (鸟嘴) that was about 15 cm long. There were also two eyeholes covered 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. (3)       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. (4)      
　　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.
