(B) first he made copies of more than twenty

(C) more than twenty were copied

(D) copies of more than twenty were made（A）

(E) he copies more than twenty of them first

请问A和B怎么选择，谢谢！

"first" here modifying " made". don't change the original position of some

adverb, such as first, only..., except sometimes, there are some apparent

fault in the original sentence.

First作为sentence adverb（修饰整句的副词？）时，用法和firstly应该是一样的

-from longman

[sentence adverb] also first of all
 used before saying the first of several things you want to say
?synonym firstly

eg： First, I'd like to thank everyone for coming.
