Any car accidentis frightening,but an accident ' in which何解?' your vehic

Question

如题所述

Answer 1

Any car accident is frightening,
but an accident in which your vehicle is thrown
into the water, with you trapped inside, is absolutely terrifying.
任何的车祸都是令人恐惧的，然而那种你的车子掉进水中而你被困车内的事故，无疑是最惊心动魄的。

in which引导了定语从句，修饰accident，做它的定语。
in which = in the accident.
从句的还原后是：In the accident your vehicle is thrown into the water, with you trapped inside
句子的主干是an accident is absolutely terrifying. in which...inside是定语从句。
