Question

【题目】People are interested in eating raw foods or whole foods partly because eating these types of food reduces the risk of acid accumulation（酸堆积）in our body.

Raw and whole foods are usually digested more efficiently than cooked and processed 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 cases, the result is obesity. When too many nutrients are absorbed at once, the body grows fat.

Processed foods contain chemical elements, which might confuse the appetite system 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（血管壁）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.

To stop this vicious circle in its tracks, people need to consume food and supplements that will balance the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore our enzyme balance. We need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If we truly want to change and help our body heal itself, we need to take an active approach.

【1】We can learn from the 2nd paragraph that __________.

A. it is essential for us to digest some fat

B. cooked and processed foods are healthier

C. foods with natural enzymes help us keep fit

D. absorbing many nutrients is beneficial to our health

【2】Processed foods will probably __________.

A. stop body’s metabolism B. be difficult to digest

C. destroy body’s cells D. lead to obesity

【3】The underlined word “ vicious ” in the last paragraph probably means __________.

A. harmful B. violent

C. progressive D. positive

【4】To change and help our body heal itself, we need to __________.

A. consume enough acid foods

B. identify enzyme production

C. avoid restoring our enzyme balance

D. eat the right types of raw and whole foods

Answer 1

【答案】

【1】C

【2】D

【3】A

【4】D

【解析】试题分析：本文属于健康类短文说明文，主要讲述了raw and whole foods的好处及这种食物对身体有好处的原因，同时还叙述了processed foods对人体的害处。为了健康，倡议人们多吃raw and whole foods。

【1】C 推理判断题。根据第二段第三句These enzymes were intended by nature to help us digest the food .可知食物中的酶可以帮助我们消化食物。再根据第四句. 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 .可知没有仔细酶的食物会让我们的身体消化不良，最后导致肥胖。也就是说酶可以帮助我保持健康。故C正确。

【2】D 细节理解题。根据第二段四、五句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 cases , the result is obesity .可知失去酶的processed foods会让我们消化不良或营养堆积在血管中，最后导致肥胖。过D正确。

【3】A 猜测词意题。在文章第三段中作者详细叙述了processed foods对人类时态带来的危害。再根据本句To stop thisviciouscircle in its tracks , people need to consume food and supplements that will balance the acid already accumulated in body .可知该词应该表示负面的含义，B项意为“暴力的”，与文章意义不搭配。A项“有害的”符合上下文串联。

【4】D 细节理解题。根据最后一段第二句Eating the right types of raw and whole foods can help .可知要想保持健康，要合适的raw and whole foods可以有很大的帮助。故D正确。
