You’re on the school bus. But as soon as you turn the corner, you find yourself at the end of a very long queue. It’s another traffic jam! It is stop-start for the rest of your journey. Meanwhile, at the same time in Antarctica(南极洲), snow covers the land. A group of emperor penguins crowd together to keep warm, using stop-and-go movements to protect themselves from the winds. Can you see the connection?
Emperor penguins move like cars in traffic jams to keep warm, that’s according to new research by the Alfred Wegener Institute, Helmholtz Center for Polar and Marina Research in Germany. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow(流动) through the whole group of penguins like a “traveling wave”.
These waves also help smaller crowds join bigger groups, keeping more and more of their friends warm. A single Antarctic “traffic jam” has thousands of penguins. Interestingly, the technology used for studying road traffic jams was used to study the penguins. This included studying time-lapse(延时) videos. Scientists also discovered that unlike on the road, these waves can be made by any penguin and in any direction.
With temperatures usually dropping below –50℃, and winds reaching speeds of up to 200km/h, these traveling waves are very important for penguins to keep warm.
These penguins can also teach us a lesson. In big groups, they learn to be orderly and patient, and to never crash into each other. These are skills we should all learn from them when we are on the road!

Many people say that they are working too many hours. They don’t have enough time to relax or to stay with their family.
Work hours are different from one country to another. In France, people spend about 1,646 hours a year at work. In Japan, however, people work about 2,159 hours a year.
Why do people work so many hours? Some people work extra hours because they want to make more money. However, many companies don’t pay overtime. Their workers don’t get more pay for more work. Some people think it’s their duty to work more hours. Some are afraid of losing their jobs if they don’t work more hours.
Many people say that their vacations are too short. In France, people get five weeks of paid vacation a year. In Germany, they get four to six weeks, and in the United States, two weeks. One study shows fewer than half of workers used all their vacation days. In Great Britain, there is a saying, “ All work and no play makes Jack a dull (迟钝的) boy.” If that is true, there must be a lot of dull people in the world.A Japanese worker works ________ more hours a year than a French one.
