标题: LZME11-51 并列连词

The commission has directed advertises 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.

(D) or anything that has been

(E) and anything

答案为Ｄ。解释说是用ｏｒ表其中一个条件，而不是用ａｎｄ表所有条件。

１．如何判断什么时候用ｏｒ，何时用ａｎｄ？

２．anything that has been　中完成时依据是什么？为何不用anything( that is) synthesized?

否定用or,这里用完时态我认为has been 早于use

并列时，如果否定就用ｏｒ吗？我怎么还没注意这个规律呢？

至于完成时，我明白了。可是在那么短的时间里看出先后，有些难呢
