问题 John has worked as a sales manager since he (join)______this company in 2002.
选项
答案 joined
解析 本题译文：约翰2002年进入公司以来，一直担任销售经理一职。
本题考查时态。现在完成时态经常和since，for连用，其结构是have／has十p.p.(动词的过去分词)，而且since后的从句时态是过去时。因此该空格处应填动词的过去式，即join的过去式joined。
  注意：现在完成时态经常和since，for连用，其结构是have／has+p.p.区别在于：since用来说明动作起始时间，for用来说明动作延续的时间长度。
  例如：(1)I have lived here since I was born．自从我出生，我就在这里生活。
  (2)I have lived here for more than twenty years．我在这里生活二十多年了。
