1. ( 1998NMET>Shirley ________ a book about China last year but I dont know whether she has finished it.
A. has written B. wrote C. had written D. was writing
分析：考查进行时态的特性之一——未完成性。从题干but I don’t know whether she has finished it这一信息句可知，该题应填过去进行时，表明去年Shirley写着一本关于中国的书，该书没写完，A、C项时态与本句所用的时间状语不符，B项表明书已在去年写完，与本文不符，故排除。答案是D。
