第7課的內(nèi)容：
一、重要句型或語法
1、過去進行時
表示過去某個時刻或某段時間正在發(fā)生的動作或行為。如：They were expecting a valuable parcel of diamonds from South Africa.
2、短語動詞中賓語的位置
1)當短語動詞中的小品詞是介詞時，無論賓語是名詞及其短語或是代詞，都要放在介詞后面。如：look for the key/look for it。
2)當短語動詞中的小品詞既可以作介詞，也可以作副詞時：如果賓語是名詞及其短語，則既可以放在動詞和小品詞之間，也可以放到小品詞后面;如果賓語是代詞，則必須放在動詞和小品詞之間。
二、課文主要語言點
The plane was late and detectives were waiting at the airport all morning. 1)注意detective(名詞，表偵探)來源于動詞detect(動詞，表偵查)。以-ive結(jié)尾的單詞大多是形容詞，所以學生較容易混淆其詞性。 2)注意機場是小地方，所以用in，而不是in。 3)all morning表示整個早上，也可以說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表示貴重的，來源于value(價值)。 3)注意區(qū)分parcel(小包裹)和package(行李包裹，一般較大)。
A few hours earlier, someone had told the police that thieves would try to steal the diamonds. 1)一段時間+earlier，表示多長時間之前。 2)可在此提問并解釋為什么要用had told，而不是told。 3)注意對比區(qū)分thief/steal/theft與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與while的用法是過去進行時中較為核心的內(nèi)容，老師可就此作詳細解釋。兩者的基本區(qū)別是：when引導的句子中，when從句動詞一般用一般過去時，而主句動詞一般用過去進行時(如果該動詞是瞬間動詞，則也用一般過去時);while引導的句子中，前后兩句話一般都用過去進行時(如果動詞為瞬間動詞，則用一般過去時)。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....，表示從某處把某物拿下來。 2)the Customs House，表示海關(guān)大樓，注意首字母要大寫。此外，custom復數(shù)時表海關(guān)，單數(shù)時一般表風俗習慣。
While two detectives were keeping guard at the door, two others opened the parcel. 1)while引導的句子前后兩句話的動詞一般都用進行時，但因為open是瞬間動詞，所以此處直接用了一般過去時。 2)keep guard，表示守衛(wèi)、守護。
To their surprise, the precisous parcel was full of stones and sand! 1)to ones surprise，表示令某人驚訝的是。 2)precious，相當于valuable，表示珍貴的。 3)be full of，表示充滿，相當于be filled with。
三、讀寫重點
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作為時間狀語，既可以放在句首，也可以放在句末。該句放在句首，是為了突出幾個小時前發(fā)生了什么事情。如果把a few hours earlier放到句末，整句話就側(cè)重強調(diào)是什么時候有人告知警察有人試圖偷鉆石了。
2、to one's surprise是固定搭配，英語里常用to one's+表示人的情感情緒的名詞，表示令人怎么樣。如：to his disappointment(令他失望的是)或是to their excitement(令他們興奮的是)。
