The plan for the new design occurred to Mr. Smith______on his work recently.A.while concentrated | B.while concentrating | C.while he concentrated | D.while concentrating himself |
|
答案
C |
解析
C 此题易选B, 认为题干是个省略句, 过去分词作时间状语。如果是省略句的话,省略的成分应该与的主句的主语和be动词相同,而且主句的主语是the plan,显然是不能作过去分词concentrated的逻辑主语的。 |
