Space X launched a cheaper, partially-used rocket into orbit. That’s a stride toward 【C1】______the price tag of sending payload to space. Successfully flying reusable rockets is a 【C2】______step toward the dream of sending people to Mars. Until now, rockets have almost all been single-use. Once the fuel is【C3】______, a rocket stage plummets to Earth, resulting in the destruction of extremely expensive equipment that costs tens of millions of dollars to build.
Its founder has likened that to 【C4】______a 747 jet after one flight, which would make air travel impossibly expensive. He has suggested that rocket launches could 【C5】______be much cheaper since the cost of the rocket propellants are less than 1 percent of the full-price ticket for a launch. So, if a rocket could be simply refueled like a jetliner for another flight, the cost of space travel could drop to a 【C6】______of what it is now. The stresses of spaceflight on reused boosters, however, are much greater than those on jetliners. The economics will depend on how many times a booster can be flown, and how much the 【C7】______expense will be to repair the booster each time.
Reusable spaceships are not a new idea. NASA’s space shuttles were the first real 【C8】______at a reusable spaceship, but the shuttles proved more 【C9】______than hoped, requiring an army of technicians to 【C10】______them between flights. As a result, they ended up being more expensive than expendable rockets.
【C1】
选项
答案
N
解析
空格前是介词,因此空格处应为介词宾语;又由空格后的名词短语“the price tag of...”可知,空格处应填入一个动名词作介词的宾语,同时与后面的名词短语构成动宾结构。上文提到,一家太空运输公司将一枚价格较为低廉的部分用过的火箭发射进入轨道,由此可知,这一举动会减少太空酬载价格,故N项slashing“大幅度削减”为答案。
