关于that A and that B问题

redli

the department defines a private passenger vehicle (as one that registered to an individual and that a gross weight has a gross weight of less than 8000 pounds.)
问题：从这题中可清楚的根据逻辑意思判断用“that and that”的形式，但有些句子意思并没有这么清晰，如何判但是用 "that A and B " or "that A and that B"

具体还得看逻辑意义。有具体的例子让咱们讨论吗？

刚做这题时想到原来有过这样的疑惑，找了一下没找到原来的题目，下次遇到我再放上来。

有that A and that B 的句型吗？ 我觉得只是这个句子的一种用法吧！ 你手头还有类似的例子吗？

tongxun

就是平行结构。

gigi

对呀！平行结构

一时找不到合适的例子，就拿这道题说说：
A report by the American Academy for the Advancement of Science has concluded that （much of the currently uncontrolled dioxins to which North Americans are exposed comes） from the incineration of wastes.
答案是：(E)many of the currently uncontrolled dioxins to which North Americans are exposed come—不必多说，OG中解释得很详细
我想讨论一下(D)many of the dioxins that are currently uncontrolled and North Americans are exposed to come
OG的解释中提到D requires that before North Americans, to be grammatically complete.
问题（就D选项的THAT问题讨论）：我觉得不加THAT，表达也很清晰。

"我觉得不加THAT，表达也很清晰。 " 去掉that 结构就变了吧！

我的问题恰恰是“为什么 North Americans are exposed to ”不可以看做从属于第一个TAHT？
