they got to the airport only ten minutes before the plane ____off 可以填would take 么
they got to the airport only ten minutes before the plane __
只能填写took.因为before後面的是从句-------主将从现,主过从过.“从过”------裏面的“过”是一般过去时,不是过去将来时,也不是过去完成时.
下面的句子是过去完成时:
They got to the airport ten minutes after the plane HAD TAKEN off .
再问: 这是时间状语从句么
再答: 对, 对,是时间状语从句。
