Lesson 7 Too late
课文内容：
The plane was late and detectives were waiting at the airport all
morning. They were expecting a valuable parcel of diamond from South
Africa. A few hours earlier, someone had told the police that thieves
would try to steal the diamonds. When the plane arrived, some of the
detectives were waiting inside the main building while others were
waiting on the airfield. Two men took the parcel off the plane and
carried it into the Customs House. While two detectives were keeping
guard at the door, two others opened the parcel. To their surprise,
the precious parcel was full of stones and sand!
本文语法：一般过去时和过去进行时的区别
语法归纳：1)一般过去时：仅描述在过去某一时间发生的某一动作。
2)过去进行时：描述在过去的某一时间段内正在发生的事情。
3)一般过去时和过去进行时在时间状语行句中的应用：
1、动作可延续，用过去进行时;动作为瞬间性的，用一般过去时。
2、动作延续时间长，用过去进行时;动作延续时间短，用一般过去时。
