Question

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. 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 the 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 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

ABBCD
1.推理判断题。说明文的题目一定和文章的说明对象有直接关系，所以做题之前了解本文的说明对象有重要意义，即raw and whole foods好、cooked and refined foods不好。而第二段中指出，natural enzymes是raw food中重要的成分，好处是什么，破坏了以后坏处是什么。所以根据这样的思路，答案为A选项。注意中文注释再次发挥极为重要的作用。
2.细节理解题。第三段一开始提到问题中的processed food，所以答案可以轻易的定位至第三段。此段一直提到各种负态度描述，所以关注最后一句的the result is weight gain and obesity，可以很容易的选出答案B选项。此段文章内容非常不好理解，但是把握阅读理解的要求，关注文章中的重点信息，题目其实并不难。如何在短时间内发掘文章中的重点信息，不受大量冗余信息干扰再次很重要，这是阅读理解考察的主要方向。
3.主旨大意题。只要知道文章的说明对象是raw and whole foods，此题就不难确定答案B选项。processed foods是用来和raw and whole foods对比以突出后者的，所以排除C选项和D选项。至于A选项的信息在68题已经考过了，再次出题的可能性就不大。
4.推理判断题。说明文的题目一定和文章的说明对象有直接关系，所以对应答案C选项。文章中只提到了raw foods好，没有说具体的烹饪方式，所以排除貌似与说明对象有关的B选项。而且raw foods经过cook以后，不就变成作者反对的cooked foods了。
5.推理判断题。结合文中的Eating the right types of raw and whole foods can help可知答案。
