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 (新陳代謝) 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（惡性的） 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.推理判斷題。說明文的題目一定和文章的說明對象有直接關系，所以做題之前了解本文的說明對象有重要意義，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，好處是什么，破壞了以后壞處是什么。所以根據(jù)這樣的思路，答案為A選項。注意中文注釋再次發(fā)揮極為重要的作用。
2.細節(jié)理解題。第三段一開始提到問題中的processed food，所以答案可以輕易的定位至第三段。此段一直提到各種負態(tài)度描述，所以關注最后一句的the result is weight gain and obesity，可以很容易的選出答案B選項。此段文章內(nèi)容非常不好理解，但是把握閱讀理解的要求，關注文章中的重點信息，題目其實并不難。如何在短時間內(nèi)發(fā)掘文章中的重點信息，不受大量冗余信息干擾再次很重要，這是閱讀理解考察的主要方向。
3.主旨大意題。只要知道文章的說明對象是raw and whole foods，此題就不難確定答案B選項。processed foods是用來和raw and whole foods對比以突出后者的，所以排除C選項和D選項。至于A選項的信息在68題已經(jīng)考過了，再次出題的可能性就不大。
4.推理判斷題。說明文的題目一定和文章的說明對象有直接關系，所以對應答案C選項。文章中只提到了raw foods好，沒有說具體的烹飪方式，所以排除貌似與說明對象有關的B選項。而且raw foods經(jīng)過cook以后，不就變成作者反對的cooked foods了。
5.推理判斷題。結合文中的Eating the right types of raw and whole foods can help可知答案。
