问题 After you_______the attached form, please send it to us within 7 working days to be eligible for our two-year warrant program.

选项 A、will complete
B、completed
C、having completed
D、have completed

答案 D

解析这里考查的是时间／条件状语从句的用法。合适的是现在时或现在完成时，选项里没有现在时，所以选择现在完成时D选项。请牢记以下句式：“引导时间／条件状语从句的连词+主语+现在时／现在完成时，主语+将来时(或祈使句)”。
