Face the Stress

    Have you had a headache during a test? Have you ever been so worried about something that you have a headache or even can't sleep at night? If so, then you know what stress is. Stress is what you feel when you are worried about something. {#blank#}1{#/blank#}You may feel angry, sad, scared, or afraid—all of which give you a stomachache or a headache.

    {#blank#}2{#/blank#}Some kinds of stress are beneficial and others are not. Good stress might happen when you're called to answer questions in class or when you have to give a speech. {#blank#}3{#/blank#} For example, you may do a better job in your test if the stress pushes you to prepare better before the test.

    On the other hand, bad stress can happen if the stress lasts too long. You may not feel well if your parents are fighting, if a family member is sick, if you're having problems at school, or if anything else makes you unhappy every day. That kind of stress isn't going to help you. {#blank#}4{#/blank#}

    {#blank#}5{#/blank#} Make sure you keep yourself in mind: Sleep, exercise, leisure, and food. If you get enough sleep and eat healthily, and if you exercise and leave and leave time for fun, you'll probably feel less stressed.

Music is good for us. According to the new study from the World Health Organization (WHO), music can 1 us happy and healthy. For example, when I feel 2 listening to some classical music helps me relax. When I'm down, I like pop music full of hope and love. It is easy for 3to fall asleep with light music. Some doctors 4 that people who love music may have a long life.

Near my house, a man and his wife have a small music house with mood music(情调音乐). People like to spend time here when 5are plying different kinds of music. Sometimes, we are lucky to hear some famous singers sing songs written by themselves. The songs are 6beautiful that we sing along with them. We communicate(交流)with one another 7 his special language. The most moving music is Chinese folk music(乡村音乐). It 8_us the sweet days in the past.

Everyone of us, rich or 9, young or old, may have his favorite song. 10 will be together with us as long as we live.

①Our body language tells the world a lot about us. But can it change the way in which we see ourselves? The answer is Yes.

②Two scientists, Amy Cuddy and Danna Carney, who know much about body language, did a famous research. According to the result of their research, body language can change the chemistry of our brains. Some high-power body language can make you become confident. For example, you will feel confident when you hold your head high; you will feel confident too when you put your arms out wide as if you have won a race. However, some low-power body language can make you feel unconfident, such as sitting with your arms close to the body, sitting with your legs together or walking with your head down.

③Why do all these happen? The scientists think the reason is that body language changes the amount of something special in our brains. It's called hormone(激素). One kind of hormone can increase your confidence; another kind can increase your stress(压力). But too much stress hormone is bad for learning. It also increases the risk of health problems.

④The result of the research is helpful for your studies. Please remember: try to use more high-power body language in your studies, and you will be confident. That is, always believe you can study well, act as if you were doing well, then you will make greater progress in real life.

Mary did not understand such sentence as "She is blue today. ""You are yellow. ""He has a green thumb. ""He has told a little white lie. " and so on. And she went to her teacher for help. 

Mary: Mrs. Smith, there is a color in each of these sentences. What do they mean?

Mrs. Smith: In everyday English, Mary, blue sometimes means sad. Yellow means afraid. A person with a green thumb grows plants very well. And a white lie is not a bad one. 

Mary: Would you give me an example for "a white lie"?

Mrs. Smith: Certainly. Now I give you some cakes. In fact, you don't like it. What will you say?"

Mary: I will say "No, thanks. I'm not hungry. "

Mrs. Smith: That's a white lie. 

Mary: Oh, I see. Thank you very much.
