I'm taking a test and have to guess the right answer to the question after the article. Article: How Does Your Body Keep the Same Temperature? 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: Why does the doctor take a person's temperature when he gets sick? Options: A: Because his temperature is a sign which can show whether he is sick or not. B: Because his temperature is always the same, no matter whether he is sick or not. C: Because when he is ill, his temperature is sure to be higher than normal. D: Because his temperature will be sure to change if something is wrong with him.

I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists warn today that the Atlantic bluefin tuna faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined. The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as PS 52,000 in the Tokyo fish markets. "In my lifetime, we've brought this big fish to the doorstep of death in the western Atlantic Ocean," said Barbara Block of Stanford University in California. "The electronic way of tracks provides the best scientific information we've ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. " Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna--in the Mediterranean and Japan--have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked. So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. "There are two ways to save the Atlantic bluefin tuna--protect them in their production grounds and in their feeding grounds," Prof. Block said. "This will need immediate action in both the central Atlantic, to reduce the loss of the big... Question: The purpose of the passage is to _ . Options: A: tell people a new way has been found to save the bluefin tuna B: call for action to save the bluefin tuna C: warn people not to eat tuna sandwiches anymore D: help scientists to find a new way to save the bluefin tuna

I'm taking a test and have to guess the right answer to the question after the article. 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: What does the text mainly talk about? Options: A: Expressions of American culture. B: Best ways to learn English well. C: Words that hurt people's feelings. D: Some expressions with the word "mouth".
