刚做了官方的模考软件，发现和findjuhl版的有一题不一样，怀疑其他题也有类似的现象。下面是从findjuhl版的prep里摘录出来的37. In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting East African cave paintings.
A.
Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting
B.
Leakey contributed to archaeology by her discovery of the earliest direct evidence of hominid activity and by painstakingly documenting
C.
Leakey was a contributor to archaeology with her discovery of the earliest direct evidence of hominid activity and with her painstaking documentation of
D.
Leakey’s contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and her painstaking documentation of
E.
Leakey’s contributions to archaeology include her discovering the earliest direct evidence of hominid activity and painstaking documentation of
这题答案是D，这是一个最完美的答案因为contributions接着句首的in addition to her work，然后后面也是两个抽象名词discovery和documentation平行。但是在我刚刚做的PREP官方模考软件里选项和答案都不是这样的！！！
In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstaking documention of East African cave paintings.
A.
Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstaking documention of B.
Leakey contributed to archaeology by her discovery of the earliest direct evidence of hominid activity and by painstakingly documenting
C.
Leakey was a contributor to archaeology with her discovery of the earliest direct evidence of hominid activity and with her painstaking documentation of
D.
Leakey’s contributions to archaeology include her discovering the earliest direct evidence of hominid activity and her painstaking documentation of
E.
Leakey’s contributions to archaeology include her discovering the earliest direct evidence of hominid activity and painstakingly documentating 这样的话，根据平行只能选A，虽然前面不符合in addition to的逻辑主语的问题。
根据这道题的提示，我总结了两点： 1、很多以前的规律大家要慎用，比如现在完成进行时出现就错（在prep里就有一道答案是这个鬼时态的）等 2、考试的时候一定要看清楚，即使遇到似曾相似的题目，你也要把题目读完读透才可以选 |
