sycdmy

The commission has directed advertisers to restrict the use of the word "natural" to foods that do not contain color or flavor additives, chemical preserva?tives, or nothing that has been synthesized.

(A)  or nothing that has been

(B)   or that has been

(C)  and nothing that is

(D)  or anything that has been

(E)   and anything

The use of do not and nothing in the same sentence creates a double negative and reverses the intended meaning. Anything should be used instead of nothing. Logically, a "natural" food cannot contain any prohibited ingredient, so the list of prohibited ingredients must be connected by or.

A The use of nothing creates a double negative

B That has been synthesized distorts the meaning by referring to foods, rather than to something added to a food

C The use of nothing creates a double negative; and should be or

D     Correct. This sentence correctly avoids a double negative and uses parallel elements.

E     And distorts the meaning of the sentence

The correct answer is D.

看了解释还是不懂为什么不能选~E选项      

红字的部分也没看懂，为什么不能用and？

susieshen

红字部分是个逻辑关系~

foods that do not contain A and B 是说不能同时有A和B，但是可以单独有A或者B

foods that do not contain A or B 是说既不能有A，也不能有B

根据题意，应该用or

所以也就说明了为什么E不对咯~~

但是我不清楚如果把E中的and改成or，这个选项对不对呢……感觉好像对~~谁帮我确定一下哈……

改成or就对了啊.

改成or，变成or anything synthesized是正确的。

多说一句，anything+过去分词，表示“任何被……的东西”，是ETS比较喜欢的结构。
