问题     It has been a hundred years since the last big one in California, the 1906 San Francisco earth quake, which helped give (1)_____ to modem earthquake science. A century later, we have a highly successful (2)_____, called plate tectonics, that explains why 1906-type earthquakes happen—along with why continents drift, mountains rise, and volcanoes (3)_____ the Pacific Rim. Plate tectonics may be one of the (4)_____ triumphs of the human mind, geology’s (5)_____ to biology’s theory of evolution. And yet scientists still can’t say when an earthquake will happen. They can’t even come (6)_____.
    What scientists can do right now is make good maps of fault zones and (7)_____ out which ones are probably due (8)_____ a rupture. And they can make forecasts. A forecast might say that, over a certain number of years, there is a certain (9)_____ of a certain magnitude earthquake in a (10)_____ spot. And that you should fix your house to its foundation and glue the water heater to the wall.
    Turning forecasts into predictions—"a magnitude 7 earthquake is (11)_____ here three days from now"—may be impossible, but scientists are doing everything they can to solve the (12)_____ of earth quakes. They break rocks in laboratories, studying how stone (13)_____ under stress. They hike (14)_____ ghost forests where dead trees (15)_____ of long-ago tsunamis. They make maps of unsecured, balanced rocks to see where the ground has (16)_____ in the past and how hard. They dig ditches across faults, searching for the active trace. They have wired up fault zones with so many sensors it is (17)_____ the Earth is a patient (18)_____ intensive care.
    (19)_____, we tell ourselves—trying hard to be persuasive—there must be some way to (20)_____ order and criterion on all that untrustworthy ground.


选项 A、quivered
B、shivered
C、trembled
D、shaken

答案D

解析 词汇辨析题。本句意为:科学家们绘制不稳定岩石群和稳定岩石群图,以探究过去什么地方发生过震颤,选shaken,意为"震动,震颤"。quiver,shiver,tremble,shake这些动词都表示不由自主的振动。其中shake是最普通的,表示"震动,抖动,晃动",例:The floor shook when she walked across the room.当她穿过房间时地板在晃动。quiver暗指轻微的、快速的、震颤的运动,如:Her lip quivered like that of a child about to cry.她的嘴唇抖动着,就象一个要哭的孩子。shiver指由于寒冷或恐惧身体瑟瑟发抖,如:He stood shivering in the cold air.他站在寒冷的微风中,冻得瑟瑟发抖。tremble意指迅速、相当轻微的运动,由于激动、虚弱或生气引起,如:I could feel the youngster’s hand tremble in mine.我能感到那个年轻人的手在我的手中颤抖。
