The irradiation of food kills bacteria and thus retards spoilage腐败. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______. 这个观点无关(因为很多食物如果不通过辐射,他们仍会因为被生吃,而不经过COOK的营养降低过程) 同时这个观点也是个误导,因为 A. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life B. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has C. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable容易腐败的 foods COOK是最后一步,而辐射用于增长储存时长。——实际上是说辐射的好,而空格处需要的是“如何误导”,显然需要填辐射的不好。而原文说“辐射和COOK一样的效用”,误导点肯定在于让人们以为辐射减少营养的量和COOK减少营养的量是一样的。这里特别注意,虽然原文说VITAMIN被辐射完全杀灭,但实际上VITAMIN只是营养的一个例子,还有很多其他的营养,可能辐射并不能完全降低他们。而C选项说“COOK是最后一步,而辐射用于增长储存时长”根本就和误导不误导没有关系,只说明了一个事实而已。 D. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is E. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded(C) E |
