Columnisteople should avoid using a certain artificial fat that has been touted as a resource for those whose medical advisers have advised them to reduce their fat intake.Although the artificial fat, which can be used in place of fat in food preparation, has none of the negative health effects of fat, it does have a serious drawback:it absorbs certain essential vitamins, thereby preventing them from being used by the body.
人们应该避免使用人造脂肪,作为真正脂肪的替代品。虽然人造脂肪替代真正脂肪不会产生真正脂肪带来的负面影响,但是它会吸收一些重要的维生素,阻止他们被身体利用。
文章推理:人造脂肪吸收维生素,阻止身体利用,因此应该避免
In evaluating the columnist's position, it would be most useful to determine which of the following?
(A) Whether increasing one's intake of the vitamins can compensate for the effects of the artificial fat
正确,如果维生素多了会影响人造脂肪的效果,还是吸收为好,如果不影响,那还是不吸收为好
(B) Whether the vitamins that the artificial fat absorbs are present in foods that contain the fat
如果使用人造脂肪天然脂肪就不再吃了,因此也就无所谓维生素是否存在于天然脂肪的食物中
(C) Whether having an extremely low fat intake for an extended period can endanger the health
没有提到关键因素维生素
(D) Whether there are any foods that cannot be prepared using the artificial fat as a substitute for other fats
没有提到维生素
(E) Whether people are generally able to detect differences in taste between foods prepared using the artificial fat and foods that are similar except for the use of other fats
没有提到维生素
也看到论坛里有人跟我一样选的B,回答的人和上面详解中的说法一样,可我还是搞不明白,为什么B不对。我觉得这道题是说 人造脂肪会吸收重要的维生素,阻碍了人的吸收,所以有缺陷。可是人造脂肪是用来替代fat的,如果含有这种维生素的食物中没有fat,就不需要使用这种人造脂肪啊,那么说人造脂肪会阻碍人对这种维生素的吸收的缺陷也就无从谈起了啊。这才是一个很重要的gap吧。反而对于A,题目已经说这是个“essential vitamins”,所以吸收它会不会compensate人造脂肪“被建议用来替代fat从而减少fat带来的负面作用的”effect其实是无关的吧,不管它能不能compensate这种effect都无法改变“人造脂肪吸收了重要的维生素,阻碍了人们的摄入”的事实啊。
请大家讨论讨论,我的思路有什么问题么?还是题目理解有误?谢谢!
