But some of their ideas are not right. “Meat is good food before you do exercise because it has much protein (蛋白质).” Wrong! You can have some food like potatoes, bread, bananas and so on. But meat is not good food before you do exercise, because the best food should have carbohydrate (碳水化合物). “The best time to exercise is early in the morning.” Wrong! Morning is a good time to exercise, but it may not be good for you. You can also exercise in the afternoon or evening. So there is no fixed time for you to exercise. “You can’t drink water when you exercise because it makes you feel tired.” Wrong! When you exercise, you must have some water during breaks. And after exercising, you must have much water. If you don’t drink enough water, then you may feel tired. “ ▲ ” Wrong! You need to give your body a day to have a break. Too much exercise is bad for your health. And remember, don’t exercise when you are very tired. 59．How many wrong ideas are mentioned (提到) in the passage? A．Two. B．Three. C．Four. D．Five. 60．Choose the best sentence to fill in the blank “ ▲ ” in the last paragraph. A．Exercising is very difficult for students. B．Exercising every day is very important.

You need to give your body a day to have a break. Too much exercise is bad for your health.”（错误！你需要给你的身体一天休息时间。太多锻炼对你的健康有害。）可知，空白处应是表达“每天锻炼非常重要”这类错误观点的句子，因为后文对其进行了否定，说明每天锻炼且不休息是错误的，B选项“每天锻炼非常重要。”符合，故选B。 61．细节理解题。根据第四段“And after exercising, you must have much water.”（并且在锻炼之后，你必须喝很多水。）可知，锻炼后喝足够的水是正确的，故选C。 62．篇章结构题。文章第一段总述人们想通过锻炼保持健康，但有些想法是错误的；第二、三、四、五段分别阐述四个错误观点及纠正，是总分结构，A选项的结构符合，故选A。 C Do you know about exercise snacks? Exercise snacks are a popular (受欢迎的) and new way for people to stay fit. Instead of spending hours exercising in playgrounds, people break that “large meal” into exercise “snacks”. You can do these exercises at many places from twenty seconds (秒) to two minutes. Then you can have a break for thirty minutes to four hours before another snack. Exercise snacks can be useful like other exercise ways. Just three exercise snacks a day can be good for your health. What’s more, there are lots of other advantages (优点). You can think more quickly and focus on your study better. Also, they can stop you from sitting too long. There are so many exercise snacks, like doing sit-ups, running and lifting weights (举哑铃). But most people don’t keep weights at their offices, so they can lift full water bottles. And if you think these exercises are boring, just turn up the music. Pick an active song and start dancing.

One day, one of his friends advised him to try Tai Chi. “Tai Chi?” asked my grandpa. “Is that a kind of tea?” His friend laughed and said, “No, it isn’t. Tai Chi is a kind of exercise. It is very slow and not difficult to learn. What’s more, it’s very good for your legs and health.” At the beginning, my grandpa didn’t want to try it. He said, “I don’t like exercising.” To help my grandpa, my family decided to give it a try. We went to a Tai Chi class with him. It seemed very easy. However, after I tried it, I found it was not easy at all. Even my brother John, the best basketball player in his school, fell a few times when he tried to do the movements (动作). But my grandpa was interested in Tai Chi at once. Guess what? Now, he goes to Tai Chi classes every day.
