1、Unit 2 Heroes 教学设计2优质公开课北师大必修1精品Unit2 Heroes教学案知识点一般过去时1) 用法：A) 表示过去某个时间发生的动作或情况。例： 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

2、句中谓语动词的时态。从句中的动作“做完手头的工作”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 talkin

3、g 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。一般过去时的时间状语应该是

4、表示过去某个时间的词或词组，如：yesterday， last month， in 1999， two days ago等，绝对不可与recently， in the past 10 years， this month等连用，因为这样的时间状语都与现在有关系，应该用现在完成时或一般现在时。B) used to do的否定形式和疑问形式很特别：你怎么写都正确。以否定形式为例：used not to do， didnt used to do， didnt use to do都对。Used to do经常与 be used to doing sth/ sth结构进行对比。前者表示过去常常或过去曾经，

5、要求加动词原形；后者表示习惯于，要求加名词或动名词。过去完成时(had done)1) 用法：表示在过去的某个时间或动作以前已经发生的动作或已经存在的状态。就是我们常说的：表示过去的过去的动作或状态。例：Until then， his family _ from him for six months.A) didnt hear C) hasnt heard B) hasnt been hearing D) hadnt heard全句的意思是：“到那时为止，他家里已经有六个月没得到他的消息了。”由此可以看出，谓语动词的动作延续到过去的某一时刻才完成，因此谓语要用过去完成时。答案是D)。其它选项中

6、：A) didnt hear，因为一般过去时只表示过去发生的事情或存在的状态，所以不能与时间状语for six months连用。B) hasnt been hearing，现在完成进行时表示过去某时刻继续到现在或现在还在进行的动作，与题意不符。C) hasnt heard，现在完成时表示从过去某一时刻到现在为止发生的动作。而题中的then只表示过去的某一时刻，不能表示现在时间。2) 注意事项：“过去的过去”这种逻辑关系常通过上下文体现出来，而不一定受某个时间状语的限制。例：There had been someone in our room just now， because I notic

7、ed a burning cigarette end on the floor when we opened the front door.(刚才有人在我们的房间里，因为我们打开前门进来时，我注意到地板上有一支仍在燃烧的香烟。)分析：虽然时间状语是just now，似乎应该使用一般过去时，但是“在房间里”这个状态是在开门和注意这两个过去的动作之前就存在的，所以应该用过去完成时。一般过去时与过去进行时的区别一般过去时表示在过去某个时间发生的动作或存在的状态，往往表示动作已完成或结束；而过去进行时则表示过去某个时间正在进行的动作，表示动作的未完成性。例如:He read a novel that
