On the surface, Mars is the picture of desolation. A barren land remains【C1】______for hundreds of millions of years, motionless【C2】______the scattering of powdery dust by a faint breeze. But perhaps just【C3】______the Martian soil, the picture is very different.
New evidence suggests the presence of a lake one mile beneath the ice-coated surface of Mars’s south【C4】______, according to new research published Wednesday in Science. Scientists say the lake【C5】______20 kilometers across, and is one meter in【C6】______The findings, if【C7】______, would mark the detection of the largest body of【C8】______water on Mars today.
The data comes from Mars Express, a European spacecraft that【C9】______Mars for 15 years.【C10】______a high-resolution camera snapped stunning images of the surface, a radar instrument probed what was【C11】______underground.
The instrument—the Mars Advanced Radar for Subsurface and Ionosphere Sounding, or MARSIS【C12】______—emits radio waves toward the planet. The waves penetrate the Martian surface and bounce off【C13】______material they come in contact with, then reflect back to the spacecraft. MARSIS【C14】______the echoes of the radio waves, which scientists can then【C15】______to decipher the composition of the subsurface.
Starting in May 2012, MARSIS【C16】______more than three years pinging a region at Mars with radio waves.【C17】______helps to look at the data yourself. In addition to an illustration that shows how Mars Express【C18】______Mars, the image【C19】______what’s called a radargram, a picture of different materials, molded out of radio waves.

选项
A、length
B、width
C、depth
D、size
答案
C
解析
固定搭配题。前半句讲的是宽,该空所在句意为“长度是一米”,因此可以推测指的是深度,length和width表示长度和宽度,与前半句意思重复,可以排除,size表示“大小”,意思不当,只有[C]depth“深度”最为恰当。
