解答

一,整句
主语 A survey
谓语 showed
宾语为that 引导的从句 that 90 percent of the 503 biggest companies and government departments questioned _______ their security systems _______ into in the previous year.
二 ,在that从句中 that 90 percent of the 503 biggest companies and government departments questioned _______ their security systems _______ into in the previous year.
主语 90 percent questioned过去分词作定语修饰公司和政府部门companies and government departments
谓语 had had 过去完成时
宾语 their security systems
宾补 broken into 为 have sth done 结构
时间状语 in the previous year.
句子意思：在2002年一份由计算机安全中心（美国的一家私人机构）进行的调查表明,在上一年在被询问的503家大公司和政府部门中有百分之九十的安全系统被闯入过.
