9．Lots of people like to take a walk on Nanjing City Wall since it ．（ ）| A． | repaired | B． | was repaired | C． | has repaired | D． | is repaired |
分析 自从南京城墙修好后，许多人喜欢在这里散步．
解答 正确答案：B．since作连词引导的时间状语从句常用一般过去时，句中it指代南京城墙，和repair是被动关系，所以此处需要一般过去时的被动结构（was/were+动词过去分词），故选择B．
点评 本题考查一般过去时的被动语态，掌握since引导的时间状语从句常用一般过去时是解题的关键．
