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!

| A．drivers can drive fast | B．drivers can drive carelessly |

| A．is caused by a traffic jam on the road |
| B．is caused by the strong wind in Antarctica |

| D．is made by just one or two penguins |
| A．needs to move orderly | B．can move as fast as it likes |
| C．will not leave others behind | D．should move as slowly as it can |
| A．penguins won’t move together if it is not very cold |
| B．traffic jams happen probably because people are impatient |
| C．penguins learn their skills from human beings |
| D．penguins are likely to crash into each other in a group |

Once thirty thousand years ago, people from northern Asia went to America. Today, we call these people Indians.
The Indians went to America because the weather began to change. Northern Asia became very cold. Everything froze. They had to move or die. How did the first Indians go to America? They walked!
Later Columbus found the New World in 1492. At first, only a few Europeans followed. They traveled to America in boats. For the next three hundred years, about 500, 000 people went there. Then the number grew very quickly. From 1815 to 1915, over thirty-two million Europeans left their countries and went to the United States. The biggest groups were from Germany and Italy. These Europeans spoke many different languages. Most of them took almost no money. They went to America so that they could find a better life.
When we do not understand each other’s language,we can talk with the help of signs.
A Frenchman was once traveling in England . He could not speak English at all. One day he went into a restaurant and sat down at a table. When the waiter came, he opened his mouth, put his fingers in it and took them out again. He wanted to say “Bring me something to eat.”
The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee. But the man again refused (拒绝) it. He shook (摇) his head whenever the waiter brought him something to drink, for drinks are not food.
When the man was going away, another man came in. This man saw the waiter, and he put his hand on his stomach (胃). That was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him.
So, you see, we cannot understand the language of signs as well as we can understand the language of words.According to the passage when people do not understand each other’s language, they cantalk with the help of ___________.
| A．a waiter | B．a teacher |
| C．an Englishman | D．their hands, heads and other parts of their bodies |

What is a supermarket? In the dictionary, a supermarket is a large self-service department store. Some supermarkets have two floors. When you enter such a supermarket, an elevator will take you to the second floor. Here you can buy things such as CDs, pens, clothes, TVs and refrigerators. After you have collected the things you want to buy on the second floor, you can go downstairs to the first floor where food and drinks are sold. You can also buy fresh fruit, vegetables and meat on this floor.
People like to go shopping in the supermarket. Here are some of the reasons.
First, the prices are reasonable. The prices are lower than in special shops and you can choose whatever you want, without going place to place.
Second, the service is excellent. You can walk around freely and no one will ask you “What can I do for you?” If you can’t find something, just ask a service person and he or she will tell you where it is at once.
Third, the quality is good. If you get home and find the food has gone bad, you can return it and they will say sorry and change it for you.
Nowadays many people don’t have much time to walk from one shop to another, so people choose to go to the supermarket in order to save time and money.
What’s more, if you don’t want to buy anything, you can just come and look around in the supermarket. It’s a good place to have a walk.
