    Now more and more people in the world are getting fatter③. This troubles them a lot. Experts(专家) say that it has a lot to do with our eating habits.

    Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than vegetables and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite①.

    It's important for us    ②  eat our meal in the same period each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges(法官) often decided whether a man was telling the truth by giving him some dry bread. If the man could not swallow(吞) the bread, it meant that he wasn't telling the truth. Because when a man is worried about something, he will have trouble in swallowing anything dry, because he loses his appetite.

    ①When you stay away from your home for a long time, you start to miss your good old bed, your good old parents. Believe it or not, you are feeling homesick(想家的). You can help yourself to feel less homesick. Here is some advice:

    ②  ▲   If you are going away from home, bring your favourite pajamas (睡衣). You can also bring some pictures of the people who you may miss. You can look at them any time you want.

    ③  ▲   The busier you are, the less time you'll have to feel homesick. Spend your free time on music, sports or books. Try to join in activities wherever you are.

    ④  ▲   You can make a plan of when you will call your mum or dad. You can also keep in touch with family and friends by emails or text messages.

    ⑤  ▲   Sometimes, telling someone that you are feeling a little homesick will help you feel better. Maybe you can tell a friend that you feel homesick and the two of you can do something fun.

    Lu Xun was an excellent writer and thinker of modern China. He took part in the May

    Fourth New Culture Movement of 1919. He could be said to have laid the foundation(基础)of modern literature(文学)in China. You couldn't believe that he almost became a doctor! So how did Lu Xun give up the study of medicine and take up writing？

    When he was young, his father fell badly ill, and little Lu Xun bought medicine for him.

    But the medicine bought from a quack doctor(庸医)did his father no good at all, and his father died. With a deep sadness and great anger, Lu Xun promised to study the most modern medical skills and help people through medicine. He studied hard, and was accepted to study in Sendai Medical College in Japan.

    However, one event changed Lu Xun's life. One day, the teacher played a film of news in class. In the film, Japanese soldiers were preparing to kill a Chinese while some Chinese were watching it with great interest, as if it had nothing to do with them. After that, Lu Xun thought he should treat the numb(麻木的)spirits of Chinese.

    For this reason, he gave up the study of medicine and moved to Tokyo. He produced a magazine with some friends there. As a writer. Lu Xun hoped that he could save Chinese people with his pen. Many of his works were translated into the leading languages, including English, Russian, German, French and Japanese.

    You are invited to a large party. Loud music is playing, and lots of people are dancing. Do you dance or talk to as many people as you can all night? Later, you cannot fall asleep-you want more conversation! Or do you prefer a quieter corner? Or perhaps you cannot wait to go home early and relax by yourself.

    Which of these people sound most like you? Person A, who tries to talk to everyone and stays late? Or Person B, who prefers to keep quiet and leaves early?

    If you said Person A, you are probably more extroverted(性格外向的) . If you said Person B. you are probably more introverted(内向的), Or perhaps you are Person C and fall somewhere in the middle. Introverted and extroverted are two commonly used words to describe a person's personality. And they are also commonly misused and misunderstood.

    Introverts may be thought as quiet, shy and timid. Extroverts may be thought as bold, confident, loud and full of energy. Introverted and extroverted people may fit those descriptions, But these same descriptions do not define(下定义) introversion and extroversion properly.

    Introverts and extroverts use their brains differently, and they get their energy differently. Introversion is the state of being mostly concerned with one's own mental life. Extroversion is the opposite. Extroversion is the state of being mostly concerned with what is outside oneself.

    People who consider themselves introverts may say they "need to be alone to charge their batteries". However, introverts may still love being social and going to parties. But such activities require time to prepare.

    Extroverts may say, "I don't need 'alone time'. 1 feel more relaxed being around other people. "Even so, extroverts can still feel unsure or not confident among other people.

    So where do you fall on the introversion/extroversion chart?
