The temperature of your body should always be the same if you are fine, no matter whether the weather is hot or cold. That is why the doctor tests your temperature with a thermometer when you are sick. Normally, your body temperature is ninety-eight point six degrees Fahrenheit . If it is higher than that, it is a sure sign that something is wrong with your body. Your body keeps the same temperature all the time, because it balances the heat it produces and the heat it gives off. It is always burning up food and producing heat. It can produce heat faster when the body needs or give off heat faster when the body becomes too warm. Let's see how this works. The heat of your body is given off chiefly through the skin. When you feel cold, your skin is tight and shows "goose flesh". When you feel chilly , you must jump around to keep warm. Then your muscles begin to work, burn up fuel and produce more heat. It is not pleasant to shiver so you usually prefer warming up by taking exercise, or put on more clothes to keep warm. When you get warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat and more body heat is used in evaporating the moisture in your body. In warm weather or warm rooms, you wear less clothing, so that heat can be given off freely. You prefer less exercise because your body is warm enough, and the extra heat produced by taking too much exercise makes you uncomfortable. Now you see why you feel differently in different kinds of weather. In summer, when it is hot, you feel tired and lazy. You do not care to work or play, but enjoy lying down and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to run and play. Question: How does the body keep the same temperature all the time? Options: A: It balances the heat it gets and loses. B: It is always producing heat from food. C: It gives off the heat that the body produces. D: It stops producing heat when it needs to.

Article: it tastes just chicken Away from home, eating is more than just a way to keep your stomach full.It is a language all its own, and no words can say, "Glad to meet you ...glad to be doing business with you ..." quite like sharing a meal offered by your host. Clearly, mealtime is not the time for you to say, "Thanks, but no thanks." Acceptance of the food on your plate means acceptance of host, country, and company.So, no matter how difficult it may be to swallow, swallow.Or, as one experienced traveler says, "Travel with a cast-iron stomach and eat everything everywhere." Often, the food offered represents proudly your host country's eating culture.What would Ataiericans think of a French person who refused to take a bite of homemade apple pie or sirloin? Our discomfort comes not so much from the thing itself; it comes from our umamiliarity with it.After all, an oyster has remarkably the same look as a sheep's eye; and a first look at a lobster would remind almost anybody of a creature from a science fiction movie, not something you dip in butter and eat.By the way, in Saudi Arabia sheep's eyes are a famous dish and in parts of China it's bear's paw soup. Can you refuse such food without being rude? Most experienced business travelers say no, at least not before taking at least a few bites.It helps, though, to slice any item very thin.This way, you minimize the taste and the reminder of where it came from.Or, " Swallow it quickly, " as one traveler recommends."I still can't tell you what sheep's eyeballs taste like." As for dealing with taste, the old line that "it tastes just like chicken" is often thankfully true.Even when the "it" is really rat or snake. Another useful piece of advice is not knowing what you are eating.What's for dinner? Don't ask. Avoid glancing into the kitchen or looking at English-language menus.Your host will be pleased that you are eating the food he offers, and who knows? Maybe it really is chicken in that soup.

Read the article and select the best answer. Article: In the English language, there are many expressions using the word "mouth". For example, if you say bad things about a person, the person might protest and say "Do not bad mouth me." Sometimes, people say something to a friend or family member that they later regret because it hurts that person's feelings. Or they tell the person something they were not supposed to tell. The speaker might say :"I really put my foot in my mouth this time." If this should happen, the speaker might feel down in the mouth. In other words, he might feel sad for saying the wrong thing. Information is often spread through word of mouth. This is general communication between people, like friends talking to each other. "How did you hear about that new movie?" someone might ask. "Oh, by word of mouth." Sometimes when one person is speaking ,he says the same thing that his friend was going to say . When this happens, the friend might say "You took the words right out of my mouth." Sometimes a person has a bad or unpleasant experience with another person ,he might say "I had my heart in my mouth." Some people have lots of money because they were born into a very rich family. You might say such a person "was born with a silver spoon in his mouth ." This rich person is the opposite of a person who lives from hand to mouth. This person is very poor and only has enough money for the most important things in life. Parents might sometimes keep sweet food from a child ad punishment for saying bad things, For example , if a child says things she should not say to her parents , she might be described as a mouthy child. The parents might even tell the child to stop mouthing off. Question: "I had my heart in my mouth " has the same meaning as " _ ".
