原来如此啊，就这么小的差别啊！我的天！

that，which最好紧跟在所修饰的对象后面。
GMAT语法里选的是相对正确的，答案是比出来的，please remember that point！
D中的that，虽然跳跃修饰也可以，但是毕竟表达没有B的修饰来的简洁明了啊~

这道题不是that修饰的问题的话，为何B比D好呢？请牛牛解释一下，谢谢！

bitieming

是的~~

谢谢楼上的解答，那我本帖问的题，That 应该是修饰 pollutants而非time了？

不过楼上的我看过That 的用法，that可以跳跃修饰啊，如何判断跳跃修饰是否正确呢，求解答！！！

that前面已经出现完整主谓宾结构时可以跳跃前面的介词结构修饰宾语中的名词，例如
0G12-126 The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.
(A) that, in turn, create unconscious physiological responses
(B) that creates unconscious physiological responses in turn
(C) creating, in turn, unconscious physiological responses
(D) to create, in turn, physiological responses that are unconscious
(E) who creates unconscious physiological responses in turn

答案A，that跳跃一个介宾结构修饰reactions这题有意思的地方还在于E干扰选项,who紧跟在individual后面，出题机构现在变得很阴险喽,如果不去理解逻辑意思只是快速看语法修饰，很容易误选E
