　　Somehow Tim managed to stop his car thirty metres beyond Dave’s burning machine. He climbed out. One of the firemen was running up the road, but he was more than a hundred metres away from the burning car. He would never get to Dave in time.

　　Tim’s racing suit would not burn for about a minute even in the hottest fire. He ran to the burning car. He could see Dave in his seat with his head on the wheel. Tim took a deep breath and stepped into the fire. He took hold of Dave’s arms, pulled him out of the car and put him on the grass. Before the fireman reached him, he had Dave’s helmet（头盔）off, but Dave was no longer breathing.

　　“We must get him away from here,” the fireman said. “It’s too dangerous.” He tried to push Tim to one side.

　　“Nobody’s moving him.” Tim said, and shook off the fireman’s hand 　　“Nobody’s moving him until a doctor comes.”
