Question: Article: Why do our eyes open wide when we feel fear? And why do our eyes become narrow when we express disgust ? According to a new research, it has something to do with survival. In a recently published paper, researchers concluded that expressions of fear and disgust changed the way human eyes gather and focus light. They argued that these changes were the result of evolutionary development and were intended to help humans survive, or at least discover, very different dangers. In order to test their hypothesis ,researchers examined two dozen volunteer college students with standard eye-exam equipment, and asked them to show expressions of fear and dislike. It was found that when the students widened their eyes, more light was admitted and their field of vision was expanded. When they wrinkled their noses in disgust, their eyes narrowed. This had the effect of blocking out more light but focusing on a specific point. Although some scientists have admitted that emotional expressions are intended primarily to communicate information, expressions of fear and disgust seem to perform different visual functions. "Eye widening may help to find a potential danger that requires much attention. And this would agree with the hypothesized function of fear," said researchers. "On the other hand, eye narrowing may help to distinguish and avoid different kinds of dangers, such as disease carriers and dirty foods. And this would agree with the hypothesized function of disgust." These findings supported naturalist Charles Darwin's view that expressions are not necessarily for communication and are not arbitrary ."If our expressions were arbitrary, they would show little cross-cultural relationship." researchers said. "But actually, our expressions probably have some universal functional principles."

Question: Article: Computers are very important to modern life.Many people think that in the future computers will be used in lots of everyday life.It is thought that we won't have to go shopping because we will be able to get most things which are sold in shops on the Internet.There will be no more books because we will be able to get all texts from computers.The Internet will be used to play games, see films and buy food.Most telephone calls will be made by computers, too. Some people are glad about those new ways of shopping and communicating .Others do not think that computers will replace our old ways. Some people think that one day we will not read books made of paper. Instead, we will buy and read books using computers, which will keep many different books in them at the same time.We won't need to turn lots of pages and paper will be saved.Computerized books will be used more and more. While many people say it is a pleasure to go into shops and look at things you want to buy.It is also unlikely that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly.Maybe computers won't change these two habits.

Question: Article: One of the greatest warriors of history, Genghis Kahn, came from the Mongolian people. He controlled many countries in Asia and Europe because of his bravery and leadership in battle. This time period was known as the Yuan Dynasty in the 13th and 14th centuries. Genghis decided to go hunting one day and many of his warriors went with him. Genghis had his favorite hawk on his wrist. The hawk was trained to fly high in the air to look for game like deer, rabbits or wild birds. When his bird flew to the ground, Genghis would follow it and shoot the wild game with his arrows. It was his favorite hobby. This particular day, game was hard to find. Toward evening, Genghis sent all the men home and decided to go another way by himself. He even let his hawk go, thinking it would fly home as well. He became thirsty so he stopped by some rocks where he noticed water was dripping. He took a cup from his pack and filled it slowly. When he put it to his mouth, he was surprised for his hawk came and spilled all the water in his cup. He thought this was very unusual so he filled the cup again. The hawk rushed down and knocked the cup free from his hand. Genghis was now thirsty and angry. As he filled the cup a fourth time, he drew his sword to stop the bird interrupting him. As the bird flew down, Genghis killed it but his cup fell deep into the rocks in the scuffle . He decided to crawl up the rock of the mountain to find the source of the water. He found a pool and noticed a huge poisonous snake was dead in the water. He realized the hawk had saved his life. His anger had caused him to kill his favorite bird. In his despair , he promised to make sure of everything before he would become angry again.
