    We all eat when we are not hungry. If we stopped eating when we were full, we would be thin , and chefs would have to find other jobs . You may be tempted to eat when you are bored, tired, angry or simply sitting in front of food that you feel like putting in your mouth. Don’t give in , the diet plans warn. Or, if you must eat , then eat only food that is so unappealing or unsatisfying that it is not worth the effort .

    It is as important for the sake of losing weight as understanding why there are times when it is extremely important to eat, however, even when there is plenty of food in your stomach. If you find yourself unable to resist snacking and give in and eat a sweet or snack, don’t blame your lack of willpower. Your brain is making you do this.

    This request for carbohydrates , for sweet or starchy ( 富含淀粉的) food is a signal that an important brain chemical needs to be made . This chemical is serotonin （ 血管收缩素）its production depends on what you eat or don’t eat . When you eat carbohydrates (apart from the carbohydrates in fruit ) , serotonin is made . When you eat protein, serotonin is not made.

    Some of us have brains that don’t make enough serotonin to last all day, and by late afternoon, we feel the effects of too little of this chemical. We become bored, have difficulty concentrating, lose patience with things that annoy us , and feel tired . Therefore, more serotonin is needed. A food scientist said. “We found out years ago in our research that , at moments like this , the brain sends out a signal saying ‘eat some carbs ’ . If we pay attention to this message and eat a bar of chocolate or cake , as soon as the snack is digested , serotonin is made and we feel better .”

    64. What does the underlined sentence“Don’t give in ” in the first paragraph mean ?

    　 A. Don’t stop eating when you are full.　 B. Don’t eat when you are not hungry.

    　 C. Eat a little more when the stomach is full . D. You would be thin if you ate less.

    65. More serotonin is made when a person ______.

    When I was very young, I had very romantic ideas about my future. First I wanted to be a ballet dancer. I often imagined myself on the stage at the Opera House with the audience cheering at the end of the show, and huge bunches of flowers at my feet. But it was soon obvious that I was going to be too tall to be a ballet dancer. Then I thought I would like to be a florist（花商）, and work in a shop full of lovely flowers. However, when I left school, I fell in love and got married, I was very happy. Then suddenly, it was all over. At the age of twenty-three I was a widow（寡妇）, and I had two little boys. I had not learned how to dance; I had not learned how to arrange flowers. The only thing I had ever learned was to look after a home. So I became a daily help, and now I go act to do house work. I’m paid by the hour, I managed to earn enough to keep the three of us.

    The two boys start school at nine o’clock, so I get up at six every morning, and, very quickly, so as not to wake them, I clean the house. Then I prepare breakfast and I wake the children at a quarter to eight. We all eat together and then I walk with them as far as the school, because there are several dangerous and busy streets to cross. I don’t have to worry too much about them at noon, as they have lunch at school. So I go to Mrs. X’s house from nine to eleven, and then to Mrs. Y’s until one o’clock. She gives me lunch, too. I work at Mrs. I’s flat from two to three-thirty every day, and then it is time for me to collect the boys from school and take them home. That is my life. It is not a very romantic one, but then, I have learned that life is not usually romantic.

    1. Before the lady got married, she wanted______.

    A. to be working on the stage in the Opera House

    B. to be either a dancer or a florist

    C. to throw flowers to her own feet

    D. to be a shop assistant

    2. At the age of twenty-three______.

    A. the lady fell in love and got married

    B. the lady formed a family of four

    C. the lady left the school and became a widow

    D. the lady’s husband died

    3. The lady learned from her experience that______.

    A. life one thinks of is different from what it really is

    B. life one thinks of is usually the same as what it really is

    C. life is usually romantic

    D. life is often cruel
