解答：

Yesterday, a businessman told me that he had bought some diamonds from South Africa. He said he wanted us to protect his diamonds, becuase the diamonds were very valuable. He was afraid of that they might be stolen.
The other day, my workmates and I went to the airport. The flight was late. We waited for the plane all the morning. At 11, the plane arrived. Five workmates and I waited inside the main building, and the others waited in the airfield. All of us were alert. We saw two men take the parcel off the plane and carry it to the Customs House.
While two of us were keeping guard near the door, the other two opened the parcel with the businessman standing near the parcel. He looked at the parcel and shouted 『Oh my God』 when the parcel was opened. We were all surprised because the strange thing, which the businessman worried about happened—the diamonds were stolen.
We contacted the airport staff as soon as possible. They provided us the record of video tape in which we found a suspicious man. And according to the information of his arrival, we got his name and address. We called the police and they went to house. The police searched his house and in a book case they found all the diamonds. This man was arrested.
