第2题

Rather than be burned to death in his blazing shell-torn Lancaster on a bombing raid o

ver Germany in 1944, Royal Air Force Gunnery Sergeant Nicholas Alkemade jumped from 18, 000 feet without a parachute (降落伞), calculating that this would be a quicker and less painful death.Unbelievably, he suffered only slight injuries. The last part of his 122-mile-per-hour fall was broken by the branches of young pine trees, thick springy undergrowth, and finally deep snow. "It was rather like bouncing on a trampoline, " he recalled.Sergeant Alkemade's experience is a dramatic rebuttal of the idea that people falling from great heights are dead before they hit the ground. Asphyxia, brought about by the speed of the fall, and heart failure through shock were thought to occur long before the final impact.The fallacy of this belief has been amply (充分地) demonstrated by free-fall parachutists who regularly drop several miles before opening their parachutes. In 1960 Capt. Joseph Kittinger jumped from a balloon in the United States and fell 16 miles before opening his parachute. He landed conscious and unhurt.

第9题

By midday, the small party of boys, led by their schoolmaster, had reached a height of 2,

500 feet. At this point the party had to stop climbing because one of the boys became seriously ill. The only thing the master could do was to return to the mountain hut where they had spent the night. From there, he telephoned the police. As no rescue party could reach the boy quickly enough, the Royal Air Force Rescue Center sent a helicopter with a policeman and a doctor on board. The helicopter soon arrived on the scene, but the Sides of the mountain were so steep that it could not land. A helicopter usually lands on four wheels, but it can land on two. However, the slope was too steep even for that. The pilot, therefore, kept the helicopter in the air with only one wheel touching the mountainside while the party carried the boy on board.

The group of boys had to stop because ______.

A．they had reached the peak

B．one of the boys was badly injured

C．one of the boys was sick

D．they had to return to the hut
