【题目】 You’re on the school bus. But as soon as you turn a corner, you '11 find yourself at the end of a very long queue. It's another traffic jam! Meanwhile, 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, according to a new research. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow(涌动) through the whole group of penguins like a "traveling wave".

These waves also help the 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 once used for studying road traffic jams was used to study the penguins. It 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 50 degrees below zero 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 a big group, they learn to be orderly and patient, and never to crash into each other. These are skills that we should all learn from them when we are on the road!

【题目】 Nowadays, we can know time very easily. Even a little child may know the time. We always ask "What time is it?".

Then people can tell us the exact time. But before the invention of clocks, knowing the time was very difficult. One way that people told the time was by using sundials, but it was impossible to tell the time on cloudy days or at night.

The first mechanical(机械的) clock was invented in China by Su Sung in 1088. The first clock in Europe was invented at the end of the 13th century.

The first watch was invented in Italy in 1462. Early watches were different from today's in two main ways. First, they only had an hour hand. Second, you could not wear them on your wrist(手腕). You had to keep them in your pocket. That s why they were called "pocket clocks".

The first wrist watch came from Switzerland 328 years later after the first pocket clock came out. But nobody bought them. They did not become popular for a hundred years.

Digital clocks and watches came from the United States and they are the most popular inventions in timekeeping. Shops all over the world started to sell them in 1971.
