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 这题能不能解释下，谢谢作者: serenity049 时间: 2010-5-4 19:48
选D吧，do not 后面根据题意不应该再跟nothing或者and，所以排除ACE，至于B中的that没有先行词，所以选D正确作者: traviszhu 时间: 2010-5-4 19:55
是不是说否定句中不用and用or？也不在加否定词？作者: serenity049 时间: 2010-5-4 20:04
如果否定句中有并列，一般都用or，当然也不能很绝对，要看具体情况。 并且也存在双重否定的情况，所以还是case-by-case problem。。。作者: cutewen 时间: 2010-5-4 21:50
否定句and>>>or nothing>>>anything 俺选了D ..不过我语法不好.. 凭初中这个知识点片面的判断选D而已。。
