    Mr North looks worried this week. He always keeps good habits. He gets up early in the 1 and does some exercises before breakfast. He thought himself 2 and didn't often go to see a doctor. But last Friday morning, when he was walking near the garden, he suddenly fell to the ground. He stood up and went back slowly. Now he thinks something is wrong with his 3 and sometimes it beats fast, but sometimes it beats slowly. He can't fall asleep in the evening. And he often feels 4 when he's at work.

    This morning Mr North came to the 5. He told the doctor what happened to him. The young doctor looked him over carefully and then said, "I'm 6 to tell you. Mr North. The terrible 7 is troubling you. You must give up coffee if you hope to live 8." "But I never drink it," said Mr North. "And stop smoking." "I don't smoke at all." "Mm! That's bad! If you don't have anything to give up, I'm afraid I can't do much for you."

    Is drinking milk the best way to get calcium? A new report says it may not be.

    "Drink your milk. It's good for you! "You've probably heard that many times, and it's true. Milk has calcium, which is necessary for keeping bones and teeth healthy and strong. The US government even says that students should drink one cup of milk at each meal.

    In 2012, however, an organization asked the government to take milk off the school lunch menu.

    The organization says, "Milk is high in sugar, high in fat and high in animal protein, all of which are not so good for health." The organization says there are better and healthier ways to get calcium, such as eating broccoli and tofu. "People talk about milk because it is going to help build strong bones," says Dr Neal Barnard, president of the organization." But drinking milk may not be the best way to get the calcium your body needs.

    Of course, calcium is important for healthy bones and teeth, but there are other ways to improve your bone strength, such as getting plenty of vitamin D and getting an hour's exercise every day.

    Some nutritionists(营养学家)disagree with the idea that milk isn't important. Keri Gans says, "I don't think it's wise to take this drink off the school menu."

    Marion Nestle, a teacher at New York University, says, "It's true that milk has healthy ingredients. Other foods have the same ingredients. It's just a food. Like other foods, too much might be a problem."

    Boys and girls, summer vacation is coming. The following is some advice on how to make your vacation meaningful and colourful.

    Take regular exercise.

    You've worked hard most of the time. So you need to join in outdoor activities, which can bring your whole body into action. You can do different kinds of exercise such as swimming, jogging and mountain climbing.

    Learn some basic life skills.

    One day, you will live alone. You can't depend on your family any longer. So you should learn to cook, wash and learn other practical skills.

    Go for a journey.

    Travel to places of interest. In this way, you can find the culture different from that of your hometown. Beautiful sights can also make you relaxed.

    Enjoy family time.

    Don't always sit in front of computer. It's great fun for family members to sit around the table, discussing sports, clothes or other common topics.

    If you follow the advice above, your summer vacation will be full of joy and meaning.
