单选题
It has been said that most of the structural faults of technical reports result from the author's ______ with what he is writing that he neglects to worry enough about how and for whom he is writing.
【正确答案】
C
【答案解析】being so concerned with…至句末都是介词from的宾语，只能用动名词。the author's作being so concerned…的逻辑主语。因为此处用的是so…that结构，所以D项being too concerned不对。全句意为：“人们认为，技术报告的结构安排不当，大多是由于作者过分关心他写的内容，而没能充分考虑他应该怎样写和为谁写报告。”
