Confidence is very important in daily life. It can help you to develop a healthy attitude (态度). A study shows that the people who are more confident are much happier. They can have more chances to make themselves successful. But how to be more confident? Here are some suggestions:

    Speak loud. When you are not confident, you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.

    Play sports. It is tiring to do physical exercise, but it can make you completely relaxed. A strong body helps you be filled with confidence.

    Encourage yourself. Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you've done.

    Get rid of(消除) fear. Fear comes along with failure (失败). But it's easy to overcome(克服) if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

    Pick up a hobby. If you like singing, sing as much as you can. In some ways, a hobby can make you outstanding. And it will make you happy and confident.

    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. . This worry in your mind can make your body feel bad. You may feel angry, sad, scared, or afraid--all of which can give you a stomachache or a headache.

    However, there are different kinds of stress. . Good stress might happen when you re called to answer questions in class or when you have; to give a speech no . For example, you may do a better job on 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. .

    The best way to fight the stress is to have a balanced life. . If you get enough sleep and eat properly, and if you exercise and leave time for fun, you'll probably feel less stressed.

    Thomas Edison lit up the world with his invention of the electric light. Without him, the world might still be in the dark. However, the electric light was not his only invention. He also invented the motion picture camera and 1,200 other things. About every two weeks he created something new.

    Thomas Edison was born in 1847. He attended school for only three months. His mother taught him at home, but Thomas was mostly self-educated. He started experimenting at a young age.

    When he was 12 years old, he got his first job. He be- came a newsboy on a train. He did experiments on the train in his spare time. Unluckily, his first work experience did not end well. They fired him when he accidentally set fire to the floor of the train. Then Edison worked for five years as a telegraph operator , but he continued to spend much of his time in experimenting his first patent(专利权) in 1868 for a vote recorder run by electricity.

    Thomas Edison was totally deaf in one ear and hard of hearing in the other, but he thought of his deafness as a blessing in many ways. It kept conversations short, so that he could have more time for work. He always worked 16 out of every 24 hours. Sometimes his wife had to remind him to sleep and eat.

    Thomas Edison died at the age of 84.He left a great many inventions that greatly improved the quality of life all over the world.
