是I've never taken the plane before 还是I had never taken the plane before.希望能说明理由,
假设我是第一次乘飞机,并且此刻我正坐在飞机上对我旁边的人说这一句话

用：I've never taken the plane before.
I'd never taken the plane before.是过去完成时.过去完成时用于发生在过去的过去的动作中,而且用过去完成时的句子中常会出现以下时间短语：before 1998(一过去年份/时间,或过去发生的动作),by the end of sth.等.例如：
I'd learnt 6,000 English words by the end of last semester.
The train had left the station before they arrived.
由于你是此刻和坐在你旁边的人说这一句话,所以用现在完成时就可以了.如果你是在过去和那人说这话,就该用I'd never taken.

是I've never taken the plane before 还是I had never taken the p The plane had taken off when i reached the airport I arrived at the airport ____ the plane had taken off． A.aft I arrived at the airport ____ the plane had taken off I arrive at the airport ——the plane had taken off. I've never seen the motherfucker like that before （）I arrived at the airport______the plane had taken off.A.a My dog had taken in into the garden 为何是in into?而不是taken it i i never took i never taken这两句话差别, I felt（）after I had taken the medicine the research disproved information I had taken for granted.怎 She showed me the photos she had taken the day before.请问是had
