Lesson 7 Too late
The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamonds 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!

练习感悟：我突然在想我要是只写继续加油是不是有点敷衍？看着去年的笔记，detectives侦探，diamonds钻石，customs House海关，keep guard at守住，我依然没有记住，内心有点复杂呀。
