reading and understand 需讲解 快来答

C It’s 2009. You feel sick, so you go to the doctor. She checks your fever, looks at your throat, and asks what you’ve been thinking about lately. When you leave，she gives you some medicine, but also a list of thinking skills that you are supposed to practice daily. She says that the way you think is causing some of your illness. Doctors and other scientists who study the human mind and try to explain why people behave in the way that do, called psychologists, are starting to believe it. You know that your brain is connected to every part of your body through your nervous system(神经系统). Now scientists have proved that how you think and feel can have an influence on the health of your body. Stress(压力，紧张) is caused whenever there is a problem or a change in your life. Of course, everybody has stress more or less; nobody’s life is perfect. In fact, stress is necessary. Without stress, we would never learn anything or grow or change. We would probably be bored to death. But too much stress can hurt you. It can weaken your body’s protection so that you are more likely to catch diseases. It can even make you more likely to have an accident. When you feel stress, your brain sends a message to your body to produce a chemical called adrenaline(肾上腺素). Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress. Problems like endless homework or troubles with your family are the kind of things you can’t fight or run away from, so you don’t use up all that adrenaline. It just stays bottled up inside you, and that’s what can do something bad to you. What can you do about stress? First, you can try to find ways to change things so you aren’t under so much stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work things out with your family or your friends. But sometimes you can’t change a stressful situation. Sometimes you don’t even want to. A big change might be a good change, but it will still be stressful. The link(关联) between your body and brain works in two ways. Your body can help your mind deal with stress. If you are under stress, you need to take especially good care of your body. It’s important to get enough sleep and eat nutritious meals. Some people take a vitamin-mineral pill every day. Another thing that you can do is daily exercise. If you go walking or do aerobic dancing or work out at the gym, you give your body a chance to burn up some of that adrenaline. Of course, a person who isn’t used to much physical activity should start slowly. Anyone with a continuing physical problem should check with a doctor before staring any exercise programs.

解题思路： 浏览全文，了解大意。
解题过程：
55题选B。属于单词含义题，用关键词psychologist定位，找到第二段第一句话：Doctors and other scientists [who study the human mind and try to explain why people behave in the way they do, called psychologists,] are starting to believe it. 定语从句的内容正好说明了psychologist的特点：（1）study the human mind. （2） explain why people behave in the way they do. 所以答案选B. thoughts and behavior. 理由是thoughts 和mind相对应，behavior与behave相对应。
56题选D。属于正误判断题。题干无法提供关键词，所以利用每一个选项中的名词进行定位。我们一一来分析 (黑体字 + 下划线是关键词)：
You shouldn’t go to the gym if you are under stress.与原文相反。
第六段第七句话：If you go walking or do aerobic dancing or work out at the gym, you give your body a chance to burn up some of that adrenaline. (去健身馆可以消耗adrenaline)
B. One can do his homework to burn up adrenaline.与原文相反。
第四段第三句话： Problems like endless homework or troubles with your family are the kind of things you can’t fight or turn away from, so you don’t use up all that adrenaline. 说明homework 不能让你用完所有的adrenaline。与选项描述的正好相反。
C. Diseases and accidents are caused by stress. 偷换概念。
第三段最后三句话：But too much stress can hurt you. It can weaken your body’s protection so that you are more likely to catch diseases. It can even make you more likely to have an accident. 很多考生错选C，原因在于把It错误理解为stress，但实际上It指代的是too much stress（过多的压力）。
D. Everyone needs stress to improve himself. 正话反说
第三段第四句话：Without stress, we would never learn anything or grow or change. （没有压力，我们就学不到任何东西，不会成长，也不会改变。） 其中grow和improve相对应。

正误判断题的关键是：用选项中的关键词快速定位答案，耐心和速度是关键。
57题选C。属于细节推断题。找到黑体字所在的位置—第五段最后一句话：A big change might be a good change, but it will still be stressful. it指代的是a big change，所以可以简单理解为A big change will still be stressful. 所以和它意思最接近的是：C. a big change will cause another stressful situation.

58题选A。属于文章主旨题。从第二段第二句话：You know that your brain is connected to every part of your body through your nervous system. 第四段第一句：When you feel stress, your brain sends a message to your body to produce a chemical called adrenaline (肾上腺素). 第六段第一句：The link（关联）between your body and brain works in two ways. 不难选出A. The Body-Brain Link (身体和大脑的关联)。
最终答案：略
