She showed me the photos she had taken the day before.请问是had taken 还是took

问题描述:

She showed me the photos she had taken the day before.请问是had taken 还是took

是had taken 因为拍照这个动作发生在给我看之前 过去完成时表示动作发生在过去的过去 showed 是过去式 take 要用过去完成时

是had taken ,因为showed用过去时,而TAKE PHOTO 发生在SHOW 之前

took
the day before.是前天.
完成时不跟具体的时间.

应该是took,因为有时间状语the day before yesterday
