In the past , people shopped for fruits, vegetables, bread and meat at small food stores and at open markets. Before there were _ , it was difficult to keep food fresh for a long time, so people shopped almost every day. Life today is very different from the past. Refrigerators keep food fresh, so people don't have to shop every day. People also have very busy lives. They have time to shop for food only once or twice a week. People shop for food in different kinds of places--in small stores, at large supermarkets and sometimes at wholesale stores that sell food and other things at very low prices. Some people even shop on the Internet. They order food online, and the company sends it to their home. And in many places around the world, people still shop at open markets. So people in different places like to shop for food in different ways. Which statement is right according to the passage? A) People like shopping on the Internet best. B) Refrigerators are very useful at home. C) People don't like shopping for food now. D) There is more and better food on the Internet

Ques: If I ask you to shut your eyes and gave you a piece of apple to eat, would you be able to tell me what it is just by tasting it? Of course, you could. Your tongue is covered with tiny "taste buds" which help you know what different foods taste like. Do you know that foods would taste different if you did not have a nose? This experiment shows how important your nose is when you taste things. What You Need: * a friend to help * small pieces of any food like carrot, orange, banana * small pieces of apple, raw potato, and onion What You Do: There are actually three different experiments. You and your friend should take turns to try them on each other. Experiment 1: Have your friend close her eyes and open her mouth. Give her a piece of the food and ask her to taste it. Then, ask her what she thinks it is. She will probably guess correctly. Experiment 2: While your friend has her eyes closed, give her a piece of the raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato (but don't call it by name) and tell you what she thinks it is. She will say it is a piece of apple! Experiment 3: (for the brave) Take a piece of raw onion. You don't have to close your eyes this time. Squeeze your nose closed with your other hand so that no smells can get into your nose. Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion. The Science Secret You already know the science secret. Your nose and your tongue work together to make food taste the way it does. Your tongue, however, can taste only certain flavors like salty, bitter, sour, and sweet. All of the other "tastes" are actually "smells," and you need your nose to "taste" them. Oh, and you might use this science secret the next time you are told to eat something you don't like the taste of. If you hold your nose while you eat it, you won't "taste" it at all. What is the most likely reason Experiment 3 is called "for the brave"? A) You keep your eyes open. B) You have to eat a raw onion. C) You have to squeeze your nose. D) You do the experiment alone.

(Q).
Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plan. So airlines offer passengers food. But it is common that they feel bad about food taste. Do you agree? To solve this problem, airlines try hard to improve their food. They would like to do so because they don't want to lose customers. However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure reduces one third of the sensibility of our taste buds . So our taste buds become senseless. The sad face, however, is that our noses don't know it. All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy food. Without doing so, the food would be tasteless. Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste. Though scientists try their best, it is not as easy as they thought. Because they can't deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them. Why do scientists feel it hard to made food on the plane taste good? A) The volunteers don't know about food taste. B) The volunteers don't understand them. C) They can't find enough volunteers. D) They can't deal with the special environment successfully.

You can't remember who sings a certain song from the 90s. You Google it. You're arguing with a friend about who played Mickey in The Goonies. You solve the problem by Googling it. You don't know the way to that new restaurant. You Google Maps it. We hold the answers to about all of life's questions in our hands today. But that means our brains are feeling free to take some rest. According to the Daily Mail, our growing reliance on the Internet for fact checking is making our memories worse. Scientists at Harvard University found people now regard Google and other search engines as an outside part of their own brains, rather than a tool. Writing in the Journal Scientific American, Harvard psychologists Daniel Wegner and Adrian Ward warn that people who believe their memorable facts that are saved online are much worse at remembering them. "The Internet is also unlike a human memory partner; it knows more and can produce the information more quickly, You can find almost all information today easily through a quick Internet search. It may be that the Internet is taking the place of people's memory." In a series of tests, researchers found it was easy for people to remember information well if they believed it would be deleted. Those who thought it was stored on a computer were more forgetful, even if they were asked to keep the information in mind. People are easy to remember things well if they know _ . A) they will lose the information B) they will lose the computer C) the information is good for them D) the information is important
