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." What is the hypothesis of the research in this text? A) Changes of human eyes lead to different emotional expressions. B) Evolutionary development helps humans survive different dangers. C) Emotional expressions affect how human eyes collect or focus light. D) Evolutionary development causes people to express different feelings.

Cooking is an important skill with an interesting history. Every culture has their own types of foods and methods of cooking. Most cities and towns have local specialties and dishes. Families often have special recipes and meals that nobody else knows how to cook. Food comes in almost as many shapes, sizes, and varieties as people do. And behind every meal and every dish there is a cook. In many cultures, especially in the West, cooking has traditionally been a task more often performed by women than by men. Today, however, it would be foolish to say cooking is only for females. Even though people are becoming busier and busier with their jobs, more and more people are cooking, including men. People cook to relax, to save money, to eat healthier foods, or just to eat tastier foods. This activity has become so popular that in the United States there is a television channel that does nothing but teach you how to cook. The internet has made it easier and easier to get all kinds of recipes. Because of globalization more types of spices and ingredients are available to more people at cheaper prices. This has helped contribute to new types of foods, dishes, and styles of cooking. Simply put, cooking is on the rise. In most places you can survive without knowing how to cook. But in my opinion if you don't know how to cook, you had better know somebody else that can cook, or life just won't be as enjoyable. Globalization has encouraged more people to cook because: A) More and more products are available at lower costs B) They are richer and can afford cooking supplies C) You can buy lots of ingredients and spices D) There are more cookbooks.
