1、 Period ThreeGrammar&Writing一、时间状语从句(在Module 5集中精析)二、过去完成时1过去完成时表示过去某一时刻或动作之前已经完成了的动作，即“过去的过去”。这个过去的时刻可以用by，before等介词短语或一个时间状语从句来表示；也可以用一个表示过去的动词来表示；还可以通过上下文来表示。The concert had already begun when I got there.我到达的时候，音乐会已经开始了。时间状语从句时间状语从句&过去完成时过去完成时2表示从过去某一时间开始，一直延续到过去另一时间的动作或状态。She said she had studi

2、ed in that college.她说她在那所学院学习过。3当一个由before，after，as soon as等连词引导的从句所表示的动作和主句的动作先后、紧接着发生时，由于这些连词本身已经说明两个动作发生的先后关系，从句和主句的谓语动词均可用一般过去时。He left the room after he(had)closed the window.他把窗户关上之后离开了房间。4在no sooner.than，hardly.when句型中，主句用过去完成时，意为“一就；刚就”。I had no sooner finished my homework than the light wen

3、t out.我刚做完家庭作业，灯就灭了。注意：若把句型中的no sooner，hardly提前放在句首时，主句用部分倒装，即提前助动词had。5有些动词，如think，hope，expect，intend，mean，suppose，want等，在用过去完成时时，可以表示过去未实现的愿望或打算。They had wanted to help，but they couldnt get there in time.他们本来是想要帮忙的，但未能及时赶到。6在 It was the first time that句型中，that从句的动词常用过去完成时。It was the first time tha

4、t he had ever spoken to a foreigner.这是他第一次跟外国人讲话。三、过去完成时与一般过去时的用法区别过去完成时是一个相对的时态，表示的是“过去的过去”，只有在和过去的某时或某一动作相比较时才用。一般过去时表示的动作是过去发生的，与现在无关。(1)在表示某人过去未曾完成的“心愿，打算；计划；想法；许诺”等时，hope，mean，plan，want，promise，intend等谓语动词必须用过去完成时。I had planned to offer you some help in your shop，but suddenly my mother fell ill

5、 yesterday.昨天我原本计划在你店里帮一些忙的，但是我妈妈突然生病了。He had meant to spend the important day with us last Sunday，but he was too busy then.上星期日他原本打算与我们一起度过这个重要的日子的，可是他当时实在太忙了。(2)如果句中出现了表示过去的具体时间状语，句子的内容为过去的实际情况或为历史事实时，句中的动词时态只能用一般过去时。The teacher said that it was Columbus who first discovered the American continent

6、.老师说是哥伦布最早发现了美洲大陆。My parents told me that I was born on May 16th,1990.我的父母告诉我，我是1990年5月16日出生的。(3)如果两个动作紧接着发生时，常常不用过去完成时，而用一般过去时，特别是在包含before和after的复合句中。After we said goodbye to the Smiths，we left their home.在我们和史密斯夫妇告别了之后，我们就离开了他们家。Just before I left Guangzhou，I sent my friend an email.在离开广州前，我给我的朋友
