补充6-7，and /or

pyndick

7. 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
我觉得and 和or在这句中都能用。大家觉得呢？D or E?

答案是D吧。
DO NOT 在这里后面自然是or.

八戒

举个例子：

not include A and B

表示A和B不同时存在，但A和B可单独存在！

而not include A or B

A或B肯定都不存在！

否定一定用OR。

以下是引用joywzy在2003-8-8 0:01:00的发言：
否定一定用OR。

就像some改any一样吗
and 要变成or?

beortobe

not a,b,c or anthing that固定用法，因为not是对后面所有内容的否定，所以如果使用nothing就无法平行了！！！
