我们学校外教给的答案,你自己翻译吧.
was your question,why didn't it say losting?
because lost is past tense.
and that describes his mind.lost.
the main action is ran,past tense of run.
the whole situation is a past event.
if the word losing were to be used,it would describe something happening at present,but we would not say losing in thought.Lost in thought it meant to describe daydreaming or being absent-minded.Losing one's mind,however,means to go crazy.
