Q: The Body Temperature The temperature of your body should be always just the same, no matter whether the weather is hot or cold. That is why the doctor uses his thermometer  when your are sick. The body keeps the same temperature all the time ,because it balances the heat it produces and it gives off. It is always burning up food and , producing heat. It can produce heat faster when it needs to give off heat than when it becomes too warm. Let's see how this happen. The heat of your body is given off mainly through the skin. When you are cold, your skin is tight and shows "good flesh". When you get chilly, you must dance around to keep warm or else you will shiver. Then your muscles begin to work, burn up fuel, and produce more heat. It is not pleasant to shiver, so you usually prefer to warm up by exercise, or put on more clothes to keep heat in. When you are 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  from your skin. You wear less clothing, too, in warm weather or warm room, so that warm can be given off freely. You feel less like exercising because your body is warm already, and the extra heat produced by exercise makes you uncomfortable. You can see from the way you feel differently in different kinds of weather. In summer, when it is warm, you feel tired and lazy. You do not care to work or play, but enjoy lying and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to play. When in summer, people prefer to  _  . A) work B) play C) do exercise D) relax and do nothing

Q: Have you ever heard that we humans use only ten percent of our brains? This opinion holds a certain appeal because if it were true, then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain! The idea that we use only a small part of the brain dates back to animal experiments in the 19th century. When scientists stimulated   a specific part of the brain,  the animal moved its leg or tail. If a tiny part of the brain could do something so great, what was the use of the rest of the brain? Some scientists assumed that large parts of the brain were simply useless. Then, in the early 20th century, scientists observed that stimulating certain parts of the brain had no physical effects. They named these seemingly useless parts of the brain the "silent cortex." Today we know that in humans, much of the "silent cortex" is actually devoted to complex activities like language, learning, and imagining. Brain scans have shown that different parts of the brain become much more active as we shift   our attention and focus, but even as we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity  ? Interestingly enough, the opposite is probably true. The less brain activity you need to perform a given task, the more the brain as a whole is able to do. If you need less brain activity to perform a task,   _  . A) you will feel sleepy B) you must shift your focus C) you can use your brain to the fullest D) you will be more productive

Q: A little girl lived in a small, very simple, poor house on a hill and as she grew she would play in the small garden. There, she was able to see over the garden fence and across the valley to a wonderful house high on the hill. This house had golden windows, so golden and shining that the little girl would dream of how magic it would be to grow up and live in a house with golden windows instead of an ordinary house like hers. Although she loved her parents and her family, she yearned to live in such a golden house and dreamed all day about how wonderful and exciting it must feel to live there. When she got to an age when she gained enough skill and sensibility to go outside her garden fence, she asked her mother if she could go for a bike ride outside the gate and down the lane. After pleading with her, her mother finally allowed her to go, insisting that she should keep close to the house and not wander too far. The day was beautiful and the little girl knew exactly where she was heading! Down the lane and across the valley, she rode her bike until she got to the gate of the golden house across on the other hill. As she dismounted her bike and leaned it against the gate post, she focused on the path that led to the house and then on the house itself. She was so disappointed as she realized all the windows were plain and rather dirty, reflecting nothing other than the sad neglect of the house that was derelict. So sad she didn't go any further and turned, and heart broken as she remounted her bike. As she glanced up she saw a sight to amaze her. There across the way on her side of the valley was a little house and its windows glistened golden as the sun shone on her little home. She realized that she had been living in her golden house and all the love and care she found there was what made her home the 'golden house'. Everything she dreamed was right there in front ofher nose! What can be inferred from the passage? A) The mother thought that she needn't keep an eye on her daughter. B) The girl was determined to go to the golden house at the beginning. C) The girl had no idea where she was heading after leaving home. D) The girl didn't love or care for her parents .
