阅读下面短文，从短文后所给各题的四个选项(A、B、C和D)中选出能填入相应空白处的最佳选项。 As she walked round the large shop, Edith realized how difficult it was to choose a suitable Christmas (36) for her father. She (37) that he were as easy to please as her mother, who was (38) satisfied with perfume. (39) , shopping at this time of the year was a most (40) job. People (41) on your feet, pushed you with their shoulders and almost (42) you over in their hurry in order to (43) something cheap ahead of you. Partly to have a rest, Edith paused in front of a counter, where some beautiful ties were on (44) . "They are (45) silk," the shop assistant told her with a smile trying to (46) her to buy one. But Edith knew from past (47) that her choice of ties hardly ever pleased her father. She moved on slowly and then, quite by chance, (48) where a small crowd of men had gathered round a counter. She found some fine pipes on sale and the (49) were very beautiful. Edith did not hesitate for long. Although her father (50) smoked a pipe once in a while, she believed this was (51) to please him. When she got home, with her small but (52) present hidden in her handbag, it was time for supper and her parents were already (53) table. Her mother was in great (54) . "Your father has at last decided to stop smoking," she told her daughter happily. Edith was so (55) that she could not say a single word.
The sudden up thrust of warm, moist air into the terrible cold of the frozen heights is what creates thunder. The sudden stronger rubbing together or two unlike forces (very warm air against very cold air) develops a kind of electricity called" static electricity". Its charges pro duce lightning and thunder. (46) Thus the violence of the thunderstorm is an almost direct result of millions of warm water drops being thrown into compatible masses of ice crystals--hitting them , rolling over them, melting them, or being frozen by them into snow or hail.Exactly how the electric charge is developed by the many, complex forces of this battle of heat and cold is still a matter of opinion. Some scientists think the action of wind against the rain is the principal factor. (47) These scientists believe the wind tears off the outer surface of each falling drops, like pulling a sweater over a child’s head, making a fine negative charge while leaving the main part of the rain drop positive. Other scientists believe that the friction of snow crystals breaking in the wind sets up the electrical charge. In reality it may well be all these factors--and more--that combine to do the work.(48) In any case, huge masses ’of electrically charged raindrops and hailstones become sorted into positive and negative reserves of electrical energy at different parts of the thundercloud, creating between them fields of very great extremes. When the resistance between these fields breaks down, the energy that is suddenly discharged is lightning.I do not know of any case of lightning directly causing an airplane accident, Cattle and sheep are more likely to be struck by lightning than are airplanes or houses. There is a recorded case that occurred on a mountainside in the western part of the United States in which one bolt of lightning killed 835 sheep. (49) Evidently the hard, dry earth offered more resistance to the lightning than the route of traveling from the ground, up one leg of an animal, through its moist’ body, and down another leg.A person’ s chances of being killed by a thunderstorm are not very great. In the United States an average of one person in 265000 dies as a result of a thunderstorm. Today houses, ships, airplanes, and electric power lines are well protected against lightning, and the. risk is de- creasing. Even a man whose work exposes him almost daily to lightning can do something about it. (50) Despite the saying that one never knows if lightning strikes him, a person can sometimes feel the bolt coming and, if quick enough take protective action in time. Evidently the hard, dry earth offered more resistance to the lightning than the route of traveling from the ground, up one leg of an animal, through its moist’ body, and down another leg.
