Q30:

Which of the following most logically completes the argument?

 

The irradiation of food kills bacteria and thus retards spoilage.  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 _______.

 

  1. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life

  2. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has

  3. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods

  4. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is

  5. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded

   Answer: E

有哪位NN能不能解释一下,完全没有思路,非常感谢

irradiating=小偷

cooking=强盗

说小偷很坏,有时候比强盗拿的钱还多,但是这是误区,因为要么1)小偷偷过了的地方强盗一般不抢;要么2)小偷和强盗一起来的时候就互相打架不做坏事了

 LS太抽象啦.

这是一道争议题,答案集中在C和E上.我还是支持E,因为食物毕竟最后还是要用来吃的.

辐射食品能够杀灭细菌,但也会降低食物的营养成份。比如,辐射会降低食物中的维生素B1。支持者认为辐射并不比烹调(cooking)更坏(含义是烹调也会是维生素减少),但是,这种说法或者是被排除的,因为一些食物是生吃的,或者是误导性的,因为____
需要在后面添加一个能使逻辑完整的句子。题干中转折很多,最后一个句子明显是either or结构,需要在含义和态度上并列,since后面是这种态度的原因。最后一个since之前的句子明显是反驳“支持者”的,基本态度应该是辐射食品是不好的,后面的原因也应该支持这种态度。
A、说支持者是谁,并不能直接指出辐射食品哪里不好。
B、无关选项,也不能表达辐射食品好不好的含义。
C、这个选项讲的是辐射食品的好处。
D、这个选项的含义是辐射食品未必不好,某些烹调方法可能更不好,是一个无关选项,而且含义与应该填上去的基本态度相左。
E、对于既是辐射的又需要烹调的食品来讲,维他命B1的减少效果是在各自过程中合成的。这说明辐射是不好的,因为效果合成,所以烹调辐射食品,维生素损失的就更多了,这说明辐射的坏处。而且,这一个选项与第一个since正好互补,说明对于生吃的和需要烹调的食物,辐射都是不好的。
