以下是引用crossmoon在2004-6-6 13:01:00的发言：
1. Not all employment selection mechanisms that have a “disparate effect,” that is, that screens out a percentage of minorities or women disproportionate to their presence in the relevant labor market, are unlawful.
(A) that is, that screens out a percentage of minorities or women disproportionate to
(B) which means, that screens out a percentage of minorities or women disproportionate with
(C) which means, that screen out a percentage of minorities or women disproportionate with
(D) that is, that screen out a percentage of minorities or women disproportionate to（D）
(E) that is, that screens out a percentage of minorities or women disproportionate with
D 第三个 that 语法上什么作用？ 是否是对mechanisms的进一步解释说明，和第一个that并列。 that is作插入语，把that is改成and语法逻辑上正确嘛？
THAT IS 改成 AND, 我觉得恐怕不行, 因为第一个THAT 从句是限制性定语从句, 而THAT SCREEN ....应该是非限制性从句, 用AND 并列后, 对原意有改变.
另外, 我没有注意到OG 是否有这样的例子:
...NOUN THAT ...AND THAT .... 或
...NOUN , THAT... AND... THAT...
是否用以下的结构会更好:
NOUN THAT....AND...
