  第7课的内容:

  一、重要句型或语法

  1、过去进行时

  表示过去某个时刻或某段时间正在发生的动作或行为。如:They were expecting a valuable parcel of diamonds from South Africa.

  2、短语动词中宾语的位置

  1)当短语动词中的小品词是介词时,无论宾语是名词及其短语或是代词,都要放在介词后面。如:look for the key/look for it。

  2)当短语动词中的小品词既可以作介词,也可以作副词时:如果宾语是名词及其短语,则既可以放在动词和小品词之间,也可以放到小品词后面;如果宾语是代词,则必须放在动词和小品词之间。

  二、课文主要语言点

  The plane was late and detectives were waiting at the airport all morning. 1)注意detective(名词,表侦探)来源于动词detect(动词,表侦查)。以-ive结尾的单词大多是形容词,所以学生较容易混淆其词性。 2)注意机场是小地方,所以用in,而不是in。 3)all morning表示整个早上,也可以说all the morning。

  They were expecting a valuable parcel of diamonds from South Africa. 1)expect表示期待、期望,常用作:expect sth.或是expect to do sth.。 2)valuable表示贵重的,来源于value(价值)。 3)注意区分parcel(小包裹)和package(行李包裹,一般较大)。

  A few hours earlier, someone had told the police that thieves would try to steal the diamonds. 1)一段时间+earlier,表示多长时间之前。 2)可在此提问并解释为什么要用had told,而不是told。 3)注意对比区分thief/steal/theft与robber/rob/robbery。

  When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. 1)when与while的用法是过去进行时中较为核心的内容,老师可就此作详细解释。两者的基本区别是:when引导的句子中,when从句动词一般用一般过去时,而主句动词一般用过去进行时(如果该动词是瞬间动词,则也用一般过去时);while引导的句子中,前后两句话一般都用过去进行时(如果动词为瞬间动词,则用一般过去时)。如:When he came in, she was reading a novel. / While she was reading a novel, he came in. 2)some..., others...,表示“一些...,另一些...”,如:Some children are playing on the playground, while others are reading in the classroom.

  Two men took the parcel off the plane and carried it into the Customs House. 1)take...off....,表示从某处把某物拿下来。 2)the Customs House,表示海关大楼,注意首字母要大写。此外,custom复数时表海关,单数时一般表风俗习惯。

  While two detectives were keeping guard at the door, two others opened the parcel. 1)while引导的句子前后两句话的动词一般都用进行时,但因为open是瞬间动词,所以此处直接用了一般过去时。 2)keep guard,表示守卫、守护。

  To their surprise, the precisous parcel was full of stones and sand! 1)to ones surprise,表示令某人惊讶的是。 2)precious,相当于valuable,表示珍贵的。 3)be full of,表示充满,相当于be filled with。

  三、读写重点

  1、尾重句:A few hours earlier, someone had told the police that thieves would try to steal the diamonds.句中的a few hours earlier作为时间状语,既可以放在句首,也可以放在句末。该句放在句首,是为了突出几个小时前发生了什么事情。如果把a few hours earlier放到句末,整句话就侧重强调是什么时候有人告知警察有人试图偷钻石了。

  2、to one's surprise是固定搭配,英语里常用to one's+表示人的情感情绪的名词,表示令人怎么样。如:to his disappointment(令他失望的是)或是to their excitement(令他们兴奋的是)。
