Unit 2 Healthy eatingOne question I’m frequently asked is ＂What’s the secret to a healthy diet?＂The answer isn’t all that mysterious. You just have to keep some basic guidelines in mind, beginning with:经常有人问我：＂健康饮食有什么秘诀？＂其实答案并不神秘。

你只需要遵循以下这些基本准则：1. Use smaller plates. 用小点的盘子。

Whether you’re already trim ortrying to lose weight, one of the bestthings you can do for your waistline andyour health is to downsize your dishware.Cornell University nutrition researcherBrian Wansink, PhD, has found that switching from a 12-inch to a 10-inch plate leads people to eat 22 percent fewer calories. If you downsized only your dinner plate, you’d be eliminating more than 5,000 calories a month from your diet. It really is that simple.不管你是已拥有苗条身材还是想减肥，掌控你的腰围和健康的最好的办法之一就是缩小餐具的尺寸。

康奈尔大学营养学研究员布莱恩·文森克博士发现，把盘子从12英寸缩小到10英寸，可以使人们少摄入22%的卡路里。

I prefer food just taken out from the freezer.Fruit, candies, nuts, chocolate, cake with buttercream frosting(糖霜 ), even peas, all of themtaste delicious when frozen. In fact, I often eat them that way.I was a kid when I picked up the habit. In my family, lots of things were thrown into the freezer— finally, two freezers — to prevent them from going bad. Among them were some of the candiesmy sisters and I had collected on Halloween.If we eat when they are still warm, we'll find ourselves taking the cookies more than we should.It's better if we can put them into the freezer and wait. That way we'll eat less and enjoy themmore because they are hard and chewing becomes a slower, more patient effort. That's the pointabout frozen buttercream frosting. Put it in your mouth at room temperature, and it's gone very quickly. But when it's frozen, you can enjoy the taste much longer as it melts(融化 ) in your mouth.The freezer treats a lot of fruit kindly. Take frozen grapes for example, I keep a bowl of grapes inmy freezer. They become a little icy, and somehow their sweetness is improved. They are perfectand healthy dessert(点心 ). This is the same with oranges, apples, bananas You might thinkbananas would get superhard- when frozen. Wrong! They become cool, creamy and sweet. If youhave wisely covered some or all of the bananas with melted chocolate before putting them intothe freeze, they will have a double taste.As long as you aren't eating anything that truly has to be hot, go ahead and experiment.A.Fruit should be frozen before one eats it.B.Frozen food is better than hot food.C.The author prefers frozen food.D.Hot food is not healthy.（2）The author began to enjoy frozen food when he _____________.A.was youngB.learned cookingC.got marriedD.got a fever（3）Why does the author NOT advise us to take hot cookies? （）A.Because they need more time to prepare.B.Because the taste is not good when they are hot.C.Because they are too delicious to avoid our overeating.D.Because we may eat them quickly and enjoy them less.（4）What does the underlined word "it" in the third paragraph refer to? （）A.The taste.B.Buttercream.C.The cookie.D.Frozen buttercream frosting.（二）Some people really don't like to be left alone with their thoughts. For example, some people takingpart in a new study preferred to receive an electric shock rather than spend 15 minutes alonein a room with nothing to do.“ The human mind wants to engage with the world, even, it appears, ifthat involves pain, ” Timothy Wilson concludes. He is a psychologist who works at the University of Virginia in Charlottesville.The brains of mammals evolved or changed slowly over generations to watch for dangers andopportunities.“ Only humans evolved the ability to think,” he says.“ Still, people can becuncomfortable controlling their own thoughts.” They maytoguidenotbethosable thoughts in apleasing or comforting direction. And that may help explain the popularity of meditation. It's aprocess in which people learn to control their thoughts and benefit from quiet contemplation沉(思 ).For its new study, Wilson's group recruited (招募 ) 146 college students. The researchers askedeach student to sit alone in a room at their lab without any devices, such as cellphones. Thissolitude lasted for 6 to 15 minutes.Most participants said they not only had trouble concentrating but also found the experience unpleasant. The researchers then asked 44 of these people to sit alone at home, too. Again,the students had the same reaction as they had in the lab. They found the experience very uncomfortable.But here's the shocker— quite literally. The scientists asked 18 men and 24 women to sit quietly and just think about anything. Their quiet, alone time lasted for entire 15 minutes. But in this experiment, the participants could give themselves a painful electric shock if they wished. That shock, though, would not make their participation in the experiment end any earlier. Still, 12 men and 6 women chose to receive a shock, rather than just continue to sit in silence. Psychologist Jonathan Schooler of the University of California, Santa Barbara, did not work on the new study. He says its findings point out how many people find it unpleasant to reflect on issues by themselves. They'd rather suffer pain than bear quiet time alone.（1）The author mentioned mammals in Paragraph 2 to show that __________.A.keeping control of thoughts is very difficultB.thinking is a kind of activity limited to humansC.mammals evolved much more slowly than humansD.mammals had poor awareness of dangers and opportunities（2）The underlined word “solitude” in Paragraph 3 can be replaced by __________.A.disappointmentB.lonelinessC.emotionD.worry（3）According to the new study, it's proved that most people __________.A.had no trouble concentratingB.enjoyed the feeling of being busyC.didn't know how to enjoy their lifeD.didn't like being alone and doing nothing（4）How did the scientists like the results of the experiment?（）A.Disappointed.B.Relieved.C.Surprised.D.Worried.（5）What's the main idea of the passage?（）A.Scientists found humans were not afraid of pain.B.The brains of humans changed slowly over generations.C.Humans prefer spending time with others to staying alone.D.People would choose pain rather than bear quiet time alone.四、任务型阅读（共10 分）Nearly everyone has spent at least one night lying in bed wishing for sleep. But for many, it's a nightly struggle. The key, or secret, is to experiment. What works for some might not work as well for others.________Set a regular bedtime. Go to bed at the same time every night.________Try not to break thisroutine on weekends when it may be attractive to stay up late. If you want to change your bedtime, help your body adjust (调整 ).________If you're getting enough sleep, you should wake up on time naturally without an alarm.As with your bedtime, try to keep your regular wake-up time even on weekends.Be smart about napping 打(盹 ). Though taking a nap can be a great way to become energeticagain, especially for older adults, it can make insomnia 失(眠 ) worse.________ If you must nap, doit in the early afternoon, and limit it to thirty minutes.Fight after-dinner drowsiness(睡意 ). What should you do when getting sleepy before your bedtime? ________ For example, washing the dishes, or calling a friend. If you give in to the drowsiness, you may wake up later in the night and have difficulty getting back to sleep.A. Wake up at the same time every day.B. Spend more time outside in the daytime.C. When it's time to sleep, make sure the room is dark.D. Get off the couch and do something to avoid falling asleep.E. If insomnia is a problem for you, consider giving up napping.F. It's important to find the sleep methods that work best for you.G. Choose a time when you normally feel tired so that you can fall asleep easily.五、语法填空（共8 分）1.The new law states that people ________ drive after drinking alcohol.2.They were both enjoying dumplings and breast of chicken ________ (cook) with garlic.3.The man who thought of ________(combine) a gas engine ________ wheels was the inventor of automobiles.4.I found your menu so ________ (limit) that I stopped ________ (worry) and started advertising the benefits of my food.5.If you don't cut ________ your smoking，I will cut ________ your supply.六、书面表达（共25 分）假如你们学校英语爱好者俱乐部对“”良好饮食习惯这一话题进行讨论，请根据下列提示，用英语写一篇发言稿。

Unit 2 Healthy eatingⅠ.阅读理解A(2017·湖北七市高三联合考试)Modern humans have a hard time controlling their desire to eat. Often you eat not because you are hungry, but because you are affected by many other things. How much you eat is strongly affected by how much those around you eat. People eating alone eat least. People eating with one other person eat 35 percent more than they do at home. People dining in a party of four eat 75 percent more. Eating with overweight friends? You'll eat more. Is your waitress overweight? you'll eat more.A wide variety of food? You'll eat more.Plates can decide how sweet dessert tastes. If people ate it off a paper plate, they'd say, “This is good.” If they ate it off a fancy silver plate, they would say, “This is the greatest cake I've eaten in my entire life.”Your knowledge about what makes food good or bad also affects how much you eat. You tend to eat more when you think the food is good, and less when you think it is bad. So Grandma's cookies always taste better than other coo kies. “Good food” even has a “health halo (光环) effect”. If we're eating something healthy, we feel that everything in that meal is healthy. Due to this, people often believe that a cheese cake with a salad has fewer calories (卡路里) than the cheese cake alone. That's perhaps also why eating organic (有机的) food might turn you into an annoying guy. Your brain may use anything that makes you feel good about your own morality to excuse your immoral behaviour.Food and hunger affect your judgment too. Hungry judges give more serious sentences. Kids who don't eat breakfast behave worse than kids who eat their breakfast. People who have low blood sugar are more likely than the average person to have trouble concentrating and controlling their unpleasant emotions.【解题导语】本文主要介绍了哪些因素会导致人们吃的更多。

课时作业(六) Unit 2 Healthy eatingSection ⅡWarming Up & Reading－Language PointsⅠ.单句语法填空1．A balanced (balance) diet and regular physical activity will help you keep fit.2．Wang Peng sat in front of his restaurant feeling (feel) very disappointed.3．Remember no one can get away with breaking (break) the law.4．They are discussing the strengths (strong) and weaknesses of the argument.5．Claire had her luggage checked (check) an hour before her plane left.6．In order to attract more customers, many supermarkets usually sell their goods at a discount at weekends.7．Too many sweets and not enough exercise will make you put on weight.8．It's certainly true that people who regularly eat breakfast tend to be slimmer (slim) and healthier.9．Out of curiosity (curious), the two children came into the cave.10．He got frustrated (frustrate) when people didn't understand what he was trying to say.Ⅱ.阅读理解Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food，get enough sleep，and exercise regularly.Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel (燃料)”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein，like meat，fish，eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性). Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles，and prevents you from gaining weight. It also improves your heart and lungs. If youfollow a regular exercise program, you will probably increase your life－span (寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.【文章大意】本文是一篇说明文。

Unit 2Healthy eating营养专家们经过仔细研究为学生准备了丰富的午餐食谱。

What's for lunch?That question is on the minds of many food experts and nutritionists.The food we eat should help us grow and develop properly.Nutritionists study food to see if it is healthful or nutritious.What we eat at lunch can satisfy about one-third of our daily food needs.So experts are studying school lunches.They believe that a healthful lunch should have many of the nutrients a student needs.A nutrient is the part of a food used by the body for growth and energy.Protein，fats，carbohydrates，vitamins，minerals，and calories，or foodenergy，are examples of nutrients.Not all foods contain the same amount or kind of nutrients.Calories supply your body with energy.Protein is used by your body to replace and build new cells.Vitamins help you to grow.Vitamin D keeps bones healthy.Minerals，such as iron，move oxygen through the body.Nutritionists have learned that too much fat，sugar，and salt is not good for you.School dietitianskeep this in mind when they plan the lunch menu.But even a well-balanced lunch will not nourish the student who just does not eat.So nutritionists are looking for ways to make school lunches taste better.Some school dietitians are adding nutrients to favorites such as pizza，tacos，and milkshakes.1．nutritionist n．营养学家2．protein n. 蛋白质3．carbohydrate n. 糖类4．dietitian n. 营养师5．nourish v t. 营养6．taco n. 墨西哥煎玉米粉卷1．What kind of food should we eat?________________________________________________________________ ________________________________________________________________ 2．Should a well-balanced lunch have too much fat，sugar and salt?________________________________________________________________ ________________________________________________________________ 【答案】 1.We should eat the food that can help us grow and develop properly.2.No.。
