example，scientists have insisted③ for years that a big enemy of health is fatty food④．However，there is increasing evidence that the real driver⑤ of poor health is not so much fatty food[2]，as it is[3]sugar．Heart disease is the number one killer of Americans．And in America，people who receive 25% of their daily calories or more Period 5　课时练案 课文整体教学(Using Language) through sugar are twice as likely to die from heart disease than people who receive less than 10% a day (Journal of the American Medical Association⑥，2014)．This is true regardless of ⑦ how healthy the rest of their diet might be．Put more simply，while people continue to argue over⑧whether or not fatty food is dangerous，we already know that sugar is a killer． Period 5　课时练案 课文整体教学(Using Language) Much of this extra sugar comes from sweets and sweet drinks．The average American gets 1/3 of his or her sugar through sweet drinks alone．The American Heart Association recommends that we limit ourselves to⑨less than 100－150 calories a day from sugar，which is less than what is usually contained in one can⑩ of sweet drink or in a single candy bar[4]．In other words，if you want to be healthy，you have to cut down on⑪ desserts，and cut out⑫ sweet drinks altogether⑬ ． Period 5　课时练案 课文整体教学(Using Language) [1]what 引导的宾语从句，作as to的宾语。 [2]that引导的同位语从句，解释说明evidence。 [3]as it is是一种语言结构，意为“事实上，实际情况是”，多用来陈述一种原因或状况。 [4]which引导的非限制性定语从句，修饰100－150 calories；其中又包含一个what引导的宾语从句，作less than的宾语。 Period 5　课时练案 课文整体教学(Using Language) Beyond this，you can keep healthy by consuming different categories⑭ of fresh foods，especially fruit and vegetables，which are full of vitamins⑮ and fibre⑯，rather than processed foods⑰ ．Processed foods often contain less nutrition，and have higher quantities⑱ of sugar，salt，and fat than fresh ingredients．Besides this，it is also important to have some meat，beans，or dairy products⑲ in your diet，as they provide the necessary protein for strong bones and muscle growth．As with⑳ everything in life，moderation㉑ is key．The ideal㉒ diet is a balanced one，without too much or too little of any one thing． Period 5　课时练案 课文整体教学(Using Language) Finally，a fundamental㉓ key to healthy eating is to eat slowly．It takes about twenty minutes from the time you start eating for your brain to tell your body that you are full．[5]What this means is that people who chew㉔ too quickly end up eating㉕ too much food because they still feel hungry．[6] Eating slowly also allows your body to digest㉖ your food better，and will allow you to enjoy your food more．In addition，studies show that consistent㉗ eating habits，for example，taking three meals a day at the same time each day，are better for our health．It is also better to eat a modest amount of food each time，rather than to eat a lot in one meal，and then a little in the next． Period 5　课时练案 课文整体教学(Using Language) [5]“It takes some time for sb．/sth．to do...”句型，意为“做……花费某人/某物多长时间”。you start eating为省略了关系词that的定语从句，修饰先行词the time。 [6] is 表语从句 Period 5　课时练案 课文整体教学(Using Language) There is no one trick㉘ to healthy eating．Rather，healthy eating starts with having a healthy attitude towards food．One question you can ask yourself is，“Do I eat to live，or live to eat？” If you are using food mostly for nutrition，then you are on the right track㉙ with your diet．However，if food has become the centre of your life，you might be on the road to bad health．It is up to you to㉚ decide how you want to live，and to make the right decisions about your diet． Period 5　课时练案 课文整体教学(Using Language) 健康饮食 当下，何为健康饮食仍众说纷纭。例如，多年来科学家一直认为健康的大敌是高脂肪食物。然而，越来越多的证据表明，不良健康的真正推手并非脂肪类食物，而是糖。心脏病是美国人的头号杀手。在美国，每天从糖分中摄取25%或更高卡路里的人死于心脏病的可能性是日摄取量少于10%的人的两倍(《美国医学会杂志》，2014年)。无论他们饮食的其他方面多么健康，都确实如此。简单地说，当人们还在为高脂肪食物是否有害而争论不休时，我们已经知晓糖分是健康杀手。 Period 5　课时练案 课文整体教学(Using Language) 多余的糖分大多来自甜食和甜饮料。一个普通的美国人单从甜饮料中摄取的糖分就占三分之一。美国心脏协会建议我们将每日糖摄入量限制在100至150卡路里以下，少于一听甜饮料或一块糖果通常所含的糖分。换言之，要想身体健康，就必须少吃甜点，完全禁饮甜饮料。 Period 5　课时练案 课文整体教学(Using Language) 除此以外，为了保持身体健康，你还可以食用不同种类的新鲜食物，尤其是富含维生素和纤维素的水果和蔬菜，而不是加工食品。相比新鲜食材，加工食品通常营养成分较低，糖分、盐分和脂肪含量更高。此外，饮食中摄取一些肉类、豆类或奶制品也十分重要，因为这些食物为强壮骨骼、肌肉生长提供必要的蛋白质。适量是关键，生活中万事均如此。理想的饮食是均衡饮食，避免过多或过少摄入任何一种成分。 Period 5　课时练案 课文整体教学(Using Language) 最后，健康饮食的基本要诀是细嚼慢咽。开始进食大约20分钟后，你的大脑才会告知你的身体“你吃饱了”。这意味着咀嚼过快的人最终会吃太多食物，因为他们仍然感到饥饿。细嚼慢咽还能让你的身体更好地消化食物、更充分地享受美食。此外，研究表明，有规律的饮食习惯对我们的健康更有好处，例如，每天固定时间食用三餐。而且最好每餐摄入适量的食物，而不是上一餐吃很多，下一餐吃得很少。 Period 5　课时练案 课文整体教学(Using Language) 健康饮食没有诀窍。相反，健康饮食始于健康的饮食态度。你可以问自己一个问题：“我是为了活着而吃饭，还是为了吃饭而活着？”如果你吃饭主要是为了汲取营养，那么你已经在饮食方面走对了路子。然而，如果食物已成为你生活的核心，那么你可能已踏上不健康之路。你想如何生活、如何做出正确的饮食决择，这完全取决于你自己。 Period 5　课时练案 课文整体教学(Using
