1. The Wallerstein study indicates that even after a decade young men and women still experience some of the effects of a divorce occurring when a child.
(A) occurring when a child
(B) occurring when children
(C) that occurred when a child
(D) that occurred when they were children（D）
(E) that has occurred as each was a child
Choice D is best.
Choice E includes an incorrect verb tense (has occurred) and wrongly replaces when with as. Also, each was does not properly refer to men and women.
OG在对E的解释中，指出有三点错误：
（1）Choice E includes an incorrect verb tense (has occurred)
（2）wrongly replaces when with as.
（3）each was does not properly refer to men and women.
1、3点比较明确。但是我不清楚为什么这里as不能取代when ？
从字典里查了as的解释：WHILE, WHEN *spilled the milk as she got up*
