2. “Have you seen the film?” he asked me. →He ask

2. “Have you seen the film?” he asked me. →He ask

是过去时，应该用had所以C不对~

a追答是错的因为have不可以用现在时对方问的时候用“seen”代表过去完成时所以c是错的

你码字码的真不容易

if,翻译为如果追答表假设而whether译为是否

He asked me whether I had seen the film.
asked [过去时] had seen [过完成时]
因为see 这动作是比ask 更早发生, 所以see 用[过去完成时]
I (had eaten) [过去完成时] an apple when my father (came) [过去时]home last night.
