新概念英语第一册第117课视频-新概念英语第一册第117-118课重点语法

第117-118课的内容：

　　一、重要句型或语法

　　1、过去进行时

　　过去进行时表示过去某个时刻或时段正在发生的事情，其形式为was/were doing。课文里出现了when和while引导的时间状语从句和并列句的用法。如：

　　When my husband was going into the dining room this morning, he dropped some coins on the floor.

　　While we were having breakfast, our little boy, Tommy, found two small coins on the floor.

　　二、课文主要语言点

　　When my husband was going into the dining room this morning,

　　he dropped some coins on the floor.

　　1)注意when后面的谓语动词一般都用did，此处when的用法与while相同。 2)drop，落下。

　　There were coins everywhere. everywhere，到处。

　　We looked for them, but we could not find them all. 1)注意look for与find的区别，look for强调过程，find强调结果。 2)all在此表示全部的硬币，用在句末，强调的是还有一些硬币没找到。

　　While we were having breakfast, our little boy, Tommy,

　　found two small coins on the floor.

　　while引导的是并列句，其谓语动词一定要用进行时。

　　He put them both into his mouth. 1)put...into...，放入。 2)both在此起强调作用。

　　We both tried to get the coins, but it was too late. both放在代词主语we后面，起到强调作用，强调我们两个人同时都想从Tommy手里抢回硬币。

　　Tommy had already swallowed them! 1)本句话的动词采用了过去完成时的时态，可在下一次课里学习。 2)swallow，吞咽。

　　Later that morning, when I was doing the housework,

　　my husband phoned me from the office.

　　1)later，后来。 2)do one's housework，做家务。 3)phone，打电话，相当于call或telephone。

　　Tommy's been to the toilet three times this morning,

　　but I haven't had any change yet!'

　　1)句中的three times是完成时的标志，所以谓语动词采用了has been to的完成时态。 2)change在此有双关的含义，一是表示零钱，二是表示变化。。

　　三、双课补充内容

　　操练过去进行时的用法，尤其是when和while的用法。
