to bed until she finished her homework.关键点二若主句谓语是延续性动词（work/live/stay/study/play/wait等）那么这个句子（主句）惯用必定式，表示动作一直延续到until所表示时间为止。until意为“直到为止”E.G.I listen to the radio until my father came back.关键点三若主句谓语动词是延续性动词，主句也可用否定式，表示某一动作到until所表示时间才发生。注意它与必定式区分：E.G.I didnt listen to the radio until my father came back.关键点四若until引导从句动作还未发生，习惯上也要用普通现在时。即：主句用普通未来时（或主句是祈使句），until引导时间状语从句通惯用普通现在时。E.G.We wont go home until the rain stops.Dont leave until we come back.第21页表示地点介词：at，in，on，over，below，to，under，in front
