Degler does more than merely summarizing existing research; he constructs a coherent picture of two centuries of studies dealing with the changing roles of women.
(A) Degler does more than merely summarizing
(B) Degler’s study is more than a mere summarizing of
(C) Degler has done more than a mere summarizing of
(D) Degler’s study has done more than summarize merely
(E) Degler does more than merely summarize
answer:E,D为什么不对？

一定是某人做了某件事，不可能是一个study do了某件事。而且语序也不对，merely summarize这个顺序才对。在从对称型考虑，后面一个句子是he constructs....所以前面也要用Degle does...
