Of the 2,000 stock investors _______ last month, 90% was found _______ financial knowledge.
A. surveyed; lacking B. having been surveyed; to lack
C. surveyed; lacked D. to have been surveyed; lack
【答案】A
【解析】
【详解】考查非谓语动词。句意：在去年受调查的2000个股票投资人之中，90%被发现缺少经济知识。根据句意可知第一空用非谓语动词作定语，stock investors和survey是被动关系，用过去分词作定语；第二空用find+宾语+宾语补足语的结构，90% of the stock investors和lack是主动关系，用现在分词作主语补足语。故选A。
