Sometimes people want to know what type of food is healthy， and what kind of food may hurt our health. The United States Department of Agriculture has prepared a small book to help people learn about which types of foods are the healthiest to eat. The book describes six basic food groups： meat， dairy products (things made from milk)， grains， fruits and vegetables. The last group is fat， oil and sweets. Asa result ofyears of research， we know that too much fat is bad for our health. For example， Americans eat a lot of meat and only a small amount ofgrains， fruits and vegetables. Because of this， they often get cancer and heart disease. In Japan， on the other hand， people eat large amounts of grains and very little meat. They also have a very low rate of cancer and heart disease. In fact， the Japanese live longer than people in any other country. Unfortunately， when Japanese people move to the United States， the rate of heart disease and cancer increases as their diet changes. Whats more， as hamburgers and other highfat foods bee mon in Japan， the rate of heart disease and cancer is increasing there as well.People are also eating more meat and dairy products in other countries such as Cuba and Hungary. Its no surprise that the disease rate in these countries is increasing along with the change in diet. Therefore， doctors everywhere advise people to eat more grains， fruits and vegetables， and eat less meat and dairy products. 2019-2020年人教版高中英语必修三教学案：Unit 2 Section 1(含答案) E AND EAT HERE (1) Wang Peng sat in his empty restaurant ①feeling very frustrated②.

Suddenly he saw his friend Li Chang hurrying by⑱.“Hello, Lao Li，” he called. “Your usual？⑲” But Li Chang seemed not to hear. What was the matter?

It was full of people. The hostess， a very thin lady, came forward. “Wele，” she said. “My name is Yong Hui. Ill help you lose weight and be fit in two weeks if you eat here every day.” Then she gave a menu to Wang Peng. There were few choices of food and drink on it: just rice, raw vegetables served in vinegar， fruit and water. Wang Peng was amazed at this and especially at the prices. It cost more than a good meal in his restaurant! He could not believe his eyes. He threw down the menu and hurried outside. On his way home he thought about his own menu. Did it make people fat? Perhaps he should go to the library and find out. He could not have Yong Hui getting away withtellingpeople lies！ He had better do some research！ At the library Wang Peng was surprised to find that his restaurant served far too much fat and Yong Huis far too little. Even though her customers might get thin after eating Yong Huis food, they were not eating enough energygiving food to keep them fit. They would bee tired very quickly. Wang Peng felt more hopeful as he drove back home. Perhaps with a discount and a new sign he could win his customers back. So he wrote： Wanttofeelfitandenergetic? eandeathere!Discountstoday!

Over time, staying awake in the night can e with a high cost. You should stop your night owl (夜猫子) habit. pared with people who turn in early, those who go to bed very late are more likely to suffer from repeated negative thoughts. The findings suggest that sleep disruption (扰乱) could actually be linked to the development of negative thoughts. Psychologists suggest that focusing on good sleep habits can help. Have you been getting into a lot of arguments lately? Theres one easy way to fix that. Too little sleep tends to leave people feeling badtempered and stressed. It means that little things that might not normally be a big deal can cause you to fly_off_the_handle. The result is more misunderstandings with those around you. Being well rested, on the other hand, will help you control your temper and youll get along better with others. According to AAA Foundation reports, people who sleep six to seven hours are twice as likely to have a car accident as those who sleep for eight hours or more when driving. People who sleep for five hours or less increase their risk up to fivefold. Go for 24 hours without sleeping, and your skills behind the wheel are the same as someone who is drunk. Research suggests that the less sleep you get, the more likely you are to be overweight. How so? When you lack sleep, you have less energy to exercise or make healthy food choices. Plus, studies show that the later you stay up, the more you eat. Night owls who stay up until 4 a．m. eat about 550 more calories than early birds who go to sleep at 10 p．m. 语篇解读：本文为说明文。晚睡有害健康，因此我们一定要尽量早一点睡，这样才能保持身体健康。 1．According to Paragraph 2, not getting enough sleep can ________. A．affect your living habits B．make you bee pessimistic C．make you suffer from diseases D．make you lose interest in everything 解析：选B　推理判断题。由第二段“The findings suggest that sleep disruption ... negative thoughts.”可知，睡眠不足可能会让你变得悲观。 2．What does the underlined part “fly off the handle” in Paragraph 3 mean? A．Fly away.　　　　　　 B．Get very angry. C．Bee very busy. D．Bee disappointed. 解析：选B　词义猜测题。由第三段画线部分前后的“Too little sleep tends to leave people feeling badtempered and stressed.”以及“The result is more misunderstandings with those around you.”可推断，画线部分是指“发怒”。 3．According to the last two paragraphs, people who lack sleep ________. A．care less about their safety B．are more likely to get drunk C．cook at home much more frequently D．may find it hard to keep a healthy weight 解析：选D　细节理解题。由最后一段“Research suggests that the less sleep you get, the more likely you are to be overweight.”可知，你睡得越少，越容易超重。故选D。 4．What is the text mainly about? A．The harm of staying up late. B．Some reasons for a lack of sleep. C．The importance of eating healthily. D．The process of forming a good habit. 解析：选A　主旨大意题。由文章内容可知，本文围绕晚睡的危害展开。 B “Old wives tales” are beliefs passed down from one generation to another. For example, most of us remember our parents telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time. Did your mother ever tell you to eat carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic (蒜) is good for you, too. It can kill the type of virus that causes colds. Unfortunately, not all of Moms advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems? Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars. Even though science can tell us that some of our traditional beliefs dont hold_water,_there is still a lot of truth in the old wives tales. After all, much of this knowledge has been accumulated (积累) from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false. 语篇解读：我们大多数人都记得父母告诉过我们要多吃某些食物或者不要去做某些事情。这些告诫是对的吗？实际上，其中一些是与现在的医学思想相符的，而另外一些却是经不起考验的…… 5．Which of the following is TRUE according to the text? A．Eating garlic is good for our eyes. B．Sticky sweets are damaging to our teeth. C．Swimming after a meal is dangerous. D．Carrots prevent people from catching colds. 解析：选B　细节理解题。由第三段最后一句“Sticky sweets ... tend to cause more problems than sweets made with simple sugars.”可以看出，sticky sweets的确对牙齿有害。 6．The author develops the third paragraph mainly ________. A．by cause and effect B．by order in space C．by order in time D．by examples 解析：选D　推理判断题。第三段第一句是主题句。接着本段举了“饭后一小时内游泳”和“吃糖”这两个例子来支持主题句。因此，这一段主要是通过举例来论述的。 7．The phrase “hold water” in the last paragraph most probably means “________”． A．to be believable B．to be valuable C．to be admirable D．to be suitable 解析：选A　词义猜测题。“dont hold water”与“there is still a lot of truth”意义相对立，那么“hold water”与“there is still a lot of truth”意义相似，因此A项正确。 8．What is the authors attitude towards “old wives tales” in the text? A．Subjective. B．Objective. C．Dissatisfied. D．Curious. 解析：选B　观点态度题。综合全文，作者既指出了一些传统说法是正确的，又说明了一些传统观念是没有科学依据的。最后一段作者表明了对这些观念的尊重，因此可以看出作者的态度是客观的。 C If youre bored with oldfashioned running, or if you feel that its not a plete workout, you might want to try crunning. It does not mean crying while running. Its actually a cross between crawling (爬行) and running that involves getting down on all fours and moving. The strange workout, best described as your thighs (大腿) worst nightmare, was invented by Australian fitness enthusiast Shaun McCarthy. The video of his crunning has been getting much attention online and it has inspired others to take up running on all fours as well. Now crunning is a steadilygrowing sport in Australia. McCarthy says that crunning is a more plete workout because it involves the upper body as well. “It really works your thighs and shoulders at the same time，” he said, adding that he believes it burns more calories as well. Some fitness experts believe that McCarthy might just be onto something there. According to Kim Baylor, a certified personal trainer, any exercise that involves full body motions leaves the chance to develop a lot of strength. However, many think crunning is likely to be out of date soon and it might even be harmful if done incorrectly. Fitness coach Kevin Dean said, “We humans are upright; our wrists have different structures than ankles. But a quadruped (四足的) animal would have four of roughly the same joint. As a result, I often see broken noses, bad wrists, and shoulder problems arising from crunning.” Health experts suggest wearing special gloves to prevent damage to hands while crunning. Its necessary to increase the intensity (强度) of exercise step by step. Crunning may be too much for a beginner and it could be bad for your neck. If it hurts severely, stop immediately and just stick to traditional running. 语篇解读：本文为说明文。如果你对跑步这一老式的健身方法感到厌烦，或者你觉得这不是一个全面的健身方式，你可以尝试一下澳大利亚的健身爱好者肖恩麦卡锡发明的“酷跑”这个新花样。 9．What do we know about crunning? A．It is running on all fours. B．Its not a plete workout. C．It is gaining worldwide popularity. D．It is created to strengthen the thighs. 解析：选A　细节理解题。由第一、二段可知，麦卡锡的“酷跑”是种四肢着地的运动，目前在澳大利亚用“酷跑”健身的人数正在逐渐增加。 10．Kim Baylors attitude to crunning is ________. A．unfavorable B．approving C．doubtful D．cautious 解析：选B　推理判断题。由第三段“McCarthy says that crunning is a more plete workout because it involves the upper body as well.”及Kim Baylor所说的话“...any exercise that involves full body motions leaves the chance to develop a lot of strength.”可知，Kim Baylor是赞同“酷跑”这个运动的。 11．What will Kevin Dean agree with? A．McCarthys idea is practical. B．Crunning is a better fitness activity. C．Crunning is not suitable for human beings. D．Its dangerous to take wholebody exercise. 解析：选C　推理判断题。由第四段可知，Kevin Dean说人类是直立行走，手腕的构造不同于脚踝，而四足动物在脚上有四个几乎一样的关节。因此他会认为“酷跑”不适合人类。 12．Whats the advice on crunning from health experts? A．Try to avoid using your neck. B．Once you begin, never give up. C．Take measures to protect your hands. D．Go as fast as possible at the beginning. 解析：选C　细节理解题。由最后一段可知，健康专家建议在“酷跑”时戴好保护性手套以避免受伤，而且锻炼的强度应一步步逐渐增大。一旦脖子疼得厉害，应立即停止“酷跑”。 Ⅱ.阅读七选五 Holidays are busy time, and if you dont make a plan for healthy meals, you will gain weight quickly and have other health problems.__1__ Here are some reasonable tips for you.
