29、nit2 Heros （Grammar）一般过去时1) 用法：A) 表示过去某个时间发生的动作或情况。例：1991年6月四级第43题I decided to go to the library as soon as I _.A) finish what I did B) finished what I didC) would finish what I was doing D) finished what I was doing结合四个选项来看，全句的意思是：“我决定一做完手头的工作就去图书馆”。本题首先要判断的是as soon as（一就）引出的时间状语从句中谓语动词的时态。从句中的动作“做

30、完手头的工作”是预计将要发生的动作，而去句的谓语动词用的是过去时（decided）。在这种场合，从句中通常用一般过去时，而不用过去将来时。所以选项A和C不可能是答案。句子指的是“完成正在做的工作”，do要用进行式。因此选项D才是答案。B) 表示过去习惯性动作。特别是由would/ used to do表达的句型，本身表示的就是过去时。例：The old man would sit on a bench in the quiet park and look at others for hours without doing anything or talking to anybody.（老人过去常常坐在宁静的公园里的一条长椅上，看着其他的人，一坐就是数个小时，什么也不干，也不和任何人交谈。）He used to visit his mother once a week.（他以前总是每周看望一次他的母亲。）C) 有时可代替一般现在时，表达一种婉转、客气、礼貌、商量的语气。例：I wanted to ask you if I could borrow your car?（我想向您借车用一用，可以吗？）Would you mind my sitting here?（您介意我坐在这里吗？）2) 注意事项：A) 注意时间状语的搭配。
