问题 Which of the following is TRUE according to Para. 1?
Which of the following is most similar to medical tomography as it is described in the passage?

选项 A、The use of ocean-current meters to determine the direction and velocity of the ocean’s mesoscale fields.
B、The use of earthquake shock-wave data collected at several different locations and combined to create a three-dimensional image of the Earth’s interior.
C、The use of a grid-point sensory system to map global weather patterns.
D、The use of subsurface floats to map large-scale circulation in the ocean.

答案B

解析 由题干most similar to medical tomography定位到原文第三段第四、五句…transmitted through the body along many different paths,is recombined to form three-dimensional images of the body’s interior.It is primarily this multiplicative increase in data obtained from the multi-path transmission of signals.推断题。通过第三段中间部分的叙述可知,医学X线断层摄影术主要是通过由不同路径穿透人体的X射线所搜集的信息重组关于人体内部的三维结构,其特点在于利用射线的变化数据来重画一幅人体结构图,这和B)中所说“从不同地点搜集地震波数据,之后重组地球内部的三维结构”不谋而合。故选B)。[避错]A)使用洋流尺度来测定紊流的方向和速度、C)使用格点感知系统来绘制全球气象模式、D)使川水下漂浮物来绘制大规模的洋流。三个选项中专业的概念在文章中都有涉及,但每个句子中形成的N1 to do N2结构无法做到和原文意思一致,故错误。
