1. remain是一个不及物动词,其后不能直接加宾语,所以where she was是状语,即其引导的是地点状语从句。 再如:She remaind in the room_ 她逗留在房间里。 题中的where she was就类似于例句中in the room,在句中充当地点状语。
2. where引导的地点状语从句有一个特点,即该从句既在主句中充当地点状语,而引导词where在从句中也充当成分。 所以,where she was是地点状语,而where又充当从句she was后面的表语。 再如:I found my wallet where I had lost it. where I had lost it是主句中地点状语,而where又在从句I had lost it中充当地点状语。
