When Neil Armstrong and Buzz Aldrin returned from the moon, their cargo included nearly fifty pounds of rock and soil, which were packed in an aluminum box with seals designed to maintain the lunar surface’s low-pressure environment. But back at Johnson Space Center, in Houston, scientists discovered that the seals had been【C1】________—by moon dust.
Lunar dust is fine, like a powder,【C2】________it cuts like glass. It’s formed when shooting stars【C3】________on the moon’s surface, heating its rocks and dirt and reducing them to fine particles. Since there’s no wind or water to smooth【C4】________edges, the tiny grains are sharp and uneven, and【C5】________nearly everything.
"The intruding【C6】________of lunar dust represents a more challenging engineering design issue, as well as a【C7】________issue for settlers, than does radiation," wrote Harrison Schmitt, an Apollo 17 astronaut, in his 2006 book, "Return to the Moon." The dust damaged space-suits and ate away layers of moon boots. Over the【C8】________ of six Apollo missions, not one rock box【C9】________its vacuum seal. Dust followed the astronauts back into their ships, too. According to Schmitt, it smelled like gunpowder and made breathing【C10】________. No one knows precisely what the extremely small particles do to human lungs.
The dust not only【C11】________the moon’s surface, but floats up to sixty miles【C12】________it—as an outer part of its atmosphere, where particles【C13】________the moon by gravity, but are so thin that they【C14】________collide. In the nineteen-sixties, Surveyor probes filmed a glowing cloud floating just above the lunar surface during sunrise. Later, Apollo 17 astronaut Gene Cernan, while orbiting the moon, recorded a【C15】________phenomenon at the sharp line where lunar day meets night. Cernan【C16】________a series of pictures illustrating the changing【C17】________; streams of particles popped【C18】________the ground and hovered, and the resulting cloud came into sharper focus as the astronauts’ orbiter approached daylight. Since there’s no wind to form and【C19】________the clouds, their origin is something of a mystery. It’s【C20】________that they’re made of dust, but no one fully understands how or why they do their thing.
【C16】
选项
A、sketched
B、described
C、received
D、copied
答案
A
解析
上文的filmed和recorded都是“拍摄”,因此空格的宾语pictures此处应理解为图画而非照片。其状语illustrating意为“用图画……说明”。因此可以推测这些画是宇航员自己画的。A项sketched有“画素描、速写”之意,符合此处的语境。B项described意为“描述”,宇航员要描述的对象是他所发现的现象,而不是图片。C项received意为“收到”,上下文没有涉及pictures的来源。D项copied意为“复印”,关于发光云的图片没有现成的。无法复印;况且复印图片不能实现阐明该现象的目的。
