Question

14．Why are people interested in eating raw foods or whole foods One reason is that eating these types of food reduces the risk of acid accumulation in your body．
    Raw and whole foods are usually digested more efficiently than cooked and refined foods．When we cook foods，we destroy the natural enzymes（酶）that are part of the food in its raw form．These enzymes were intended by nature to help us digest the food．When we consume food without these natural enzymes，our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream．In both instances，the result is obesity．When too many nutrients are absorbed at once，the body grows fat．Improperly digested food moves slowly through the digestive tract，where it becomes increasingly acidic （酸性的）．To protect its vital organs from this acidic waste，the body changes the acid into fat and stores it safely away from the organs．
    Processed foods contain chemical elements，which might confuse the appetite mechanism that tells us when we've had enough to eat； as a result，people often overeat．Processed foods also upset the digestive cycle．The body will either identify these foods as allergens and then store them safely away from the organs as fat，or the remains of undigested food will become acidic and enter the bloodstream as acid waste，which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells．The body's metabolism（新陈代谢） becomes inactive，and then result is weight gain and obesity．
    The accumulation of acid in the digestive tract makes digestion increasingly inefficient．When that happens，even healthy foods can become acidic and the food allergies will become more common．
    To stop this vicious（恶性的） circle in its tracks，people need to consume food and supplements that will neutralize （使…中和）the acid already accumulated in body．Eating the right types of raw and whole foods can help．It's also important to restore your enzyme balance．You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production．If you truly want to change and help your body heal itself，you need to take an active approach．．

Answer 1

分析 本文讲述的raw foods or whole foods对人体的好处，倡导人们多食用这样的健康的食品．

解答 30．C 推理判断题．根据文章第一段可知eating raw foods or whole foods可以减少体内acid的积累，可以让我们的消化更为有效健康．说明本文的目的在于建议人们多吃这样的食物．故C正确．
31．A 推理判断题．根据文章第二段1，2行Raw and whole foods are usually digested more efficiently than cooked and refined foods．When we cook foods，we destroy the natural enzymes （酶） that are part of the food in its raw form．可知含有the natural enzymes （酶）的食物可以帮助我们更高效地消化食物．帮助我们保持健康．故B正确．
32．B 细节理解题．根据文章第二段3，4，5行When we consume food without these natural enzymes，our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream．In both instances，the result is obesity．可知这些处理过的食物会导致人们发胖．故C正确．

点评 本文主要考查推理判断题．要求在理解原文表面文字信息的基础上，做出一定的推理判断，从而得到文章的隐含意义和深层意义．推理判断题所涉及的内容可能是文中的某一句话，也可能是某几句话，所以，推理题的答案只能是根据原文表面文字信息一步推出的答案：即对原文某一句话或某几句话所作的同义改写或综合．推理判断题的题干中通常含有infer，suggest，imply，conclude  indicate等标志性词语． 这种题型主要包括细节判断题、态度观点推断题、写作意图推断题、文章出处判断题和猜测想象推断题
