Calories consumed in excess of those with which the body needs to be provided to maintain its weight are normally stored as fat and the body gains weight. Alcoholic beverages are laden with calories. However, those people who regularly drink two or more alcoholic beverages a day and thereby exceed the caloric intake necessary to maintain their weight do not in general gain weight.
Which one of the following, if true, most helps to resolve the apparent discrepancy?
A) Some people who regularly drink two or three alcoholic beverages a day avoid exceeding the caloric intake necessary to maintain their weight by decreasing caloric intake from other sources.
B) Excess calories consumed by people who regularly drink two or three alcoholic beverages a day tend to be dissipated as heat.
C) Some people who do not drink alcoholic beverages but who eat high calorie foods do not gain weight.
D) Many people who regularly drink more than 3 alcoholic beverages a day do not gain weight.
E) Some people who take in fewer calories than are normally necessary to maintain their weight do not lose weight.

没给答案，我个人觉得应该选B，不知道大家怎么看呢？

我个人觉得选A，此处的discrepancy应该是指科学理论（或过多酒精饮料会卡路里过剩，脂肪过多）和事实（过量饮酒的人总的来说并不没有增重），因此，如果过量饮酒精的人注意其他方面能量的摄入，以维持体重的话，不增重就解释的通了~

B的解释和原文中说excess calories are stored as fat矛盾了吧~

个人觉得A不对。
这里有个中心语限定范围的问题，在这一题中中心语是 people who regularly drink two or more alcoholic beverages a day ，它在题目中的限定范围是in general ，也就是说：那些每天喝超过2瓶酒的人“通常”是不会增加体重的。
A选项对同一中心语的限定范围是Some,说：这是因为他们中的”有些人“通过其他因素减少卡路里，所以不会增加体重。与题目在范围上发生了冲突。

在看B选项说：那些每天喝超过2瓶酒的人所吸收的卡路里会通过散热的形式排放出去，而不是STORED AS FACT。原题说Calories consumed in excess of those with which the body needs to be provided to maintain its weight are normally stored as fat ，用了一个”normally“，就意味着有abnormal的情况发生。而B选项的”散热“正好是这种abnormal的情况，从而剪断了Excessive Calories 和 GAIN FAT之间的关系，于是解释了原题的矛盾。

我觉的是B

B
第一句说过量的卡路里通常是脂肪形式存储在体内，所以会胖。
经常喝酒的人，如果过量卡路里不以脂肪形式存储，例如B所说的，热量形式散发，则不会胖。

A不对是因为thereby exceed the caloric intake necessary to maintain their weight ，光喝酒的能量摄入已经超过了维持体重不变的能量摄入，换言之其他饮食的能量摄入多还是少，总量都是超过了。A直接就和原文意思违背了
