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、even if
B、as though
C、in general
D、so that

答案B

解析 逻辑衔接题。本句包括一个由so…that构成的结果状语从句,而且省略了that,完整的句子应该是:They have wired up fault zones with so many sensors that it is…,主句讲"科学家们用很多传感器将断层带连接起来",从句提到"接受精心照料的病人",显然,这是一个比喻的用法,因此选择连接词as though"好象,仿佛"。even if"即使";in general"通常,大体上,一般而言";so that"所以,因此";这三个短语均不合题意。
