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
OG解释：Logically, a “natural” food cannot contain any prohibited ingredient, so the list of prohibited ingredients must be connected by or.
也就是说foods必须不包含color or flavor additives, chemical preservatives, anything that has been synthesized中的任何一样！！ 不考虑选项问题，只考虑这个连词，为什么要用or，而不用and呢？ OG对and的解释是 And distorts the meaning of the sentence，怎么了distort？？？
那你的意思是不是就是在否定句中，用and连接几个并列成分时，表示的是其中任意几个可以...，但所有成分不能同时... 但是or是表示所有成分不能同时... 对么？作者: zyq19911205 时间: 2012-7-19 09:24

not caused by A,B and C ,意味不是由A,B,C的组合而引起的,也就是combination 而 not caused by A, B or C，意味着不是由A或B或C任何一个引起的，也就是individually---By Elroy大侠 两道题都是这个原则的~~ 你再好好想想哦作者: zyq19911205 时间: 2012-8-8 20:13
