David will never forget what happened to him the day before yesterday. He (eat) something at home when he received a strange phone call from a hospital. The caller said that his son (fall) to the ground unconscious on the way to school. It was he took him to the hospital. David hung up his cellphone and rushed to his son's classroom, only to find him listening to the teacher attentively. He suddenly realized that he had been cheated, but he felt (relieve). Just at that time the phone rang again, saying, "Your son is in great danger and he needs immediate operation which costs 48,000 yuan. The doctors here say they will not operate your son until they receive the money." When (ask) from where the caller had taken his son to hospital, the caller rang off. David gave a big smile and said, "What a pity!"
If the cheater thought he could get money from David in such a(n)(honest) way, he was wrong. Such phone calls are common these days. A few of them might have fallen victims to such tricks. Most parents are sensitive to (they). It was really silly to cheat educated men like David.
Believe it or not, it's a true story. The (colleague) in his office can confirm it, such as Tom, Peter and so on.
