饭饭七

14. The commission has directed advertisers to restrict the use of the word "natural" to foods that do not contain color or flavor additives, chemical preserva­tives, 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

Idiom + logical predication

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

这里or与and的区别要如何理解呢？？？

and 表示并存，与文意不符，文意是只要含有任意一样这些东东的食品都不能算天然食品，用and就表示只要含有这个东东和那个东东就不算天然食品，这就改变了文意

前面有do not contain的否定词的话，后面连接词一般用or,不用and
