接下去我们来看第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 sth./sb. 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)。
四、语用文化
可简单介绍钻石的基本知识。
五、教学建议
1、注意对比第一册第117-118课中的过去进行时的用法。在第117课中,when和while的用法有相同之处,但实际使用中,这种情况不多见。
2、短语动词中宾语的位置是较为容易出错的,需要提醒学生注意。
