单选题
Astronaut Jim Voss has enjoyed many memorable moments in
his career, including three space flights and one space walk. But he recalls
with special fondness a decidedly earthbound(只在地球上的)experience in the summer of
1980 when he participated in the NASA-ASEE Summer Faculty Fellowship Program.
Voss, then a science teacher at West Point was assigned to the Marshall Space
Flight Center's propulsion(推进)lab in Alabama to analyze why a hydraulic fuel
pump seal on the space shuttle was working so well when previous seals had
failed. It was a seemingly tiny problem among the vast complexities of running
the space program. Yet it was important to NASA because any crack in the seal
could have led to destructive results for the astronauts who relied on
them. "I worked abit with NASA engineers," says Voss, "but I
did it mostly by analysis. I used a handheld calculator, not a computer, to do a
thermodynamic(热力学的)analysis." At the end of the summer, he, like the other
NASA-ASEE fellows working at Marshall summarized his findings in a formal
presentation and detailed paper. It was a valuable moment for Voss because the
ASEE program gave him added understanding of NASA, deepened his desire to fly in
space, and intensified his application for astronaut status. It
was not an easy process. Voss was actually passed over when he first applied for
the astronaut program in 1987. Since then he has participated in three space
mission. The 50-year-old Army officer, who lives in Houston, is now in training
for a four-month mission as a crew member on the International Space Station
starting in July 2000. Voss says the ASEE program is wonderful
for all involved. "It brings in people from the academic world and gives NASA a
special property for a particular period of time. It brings some fresh eyes and
fresh ideas to NASA, and establishes a link with colleges and universities,"
Voss explains. "There is an exchange of information and an exchange of
perspectives that is very important." For the academic side,
Voss says, the ASEE program also "brings institutions of higher learning more
insight into new technology. We give them an opportunity to work on real-world
problems and take it back to the classroom."
单选题

A.Because previous seals all failed.
B.Because it was very complex in running the space program.
C.Because great care has to be taken of the hydraulic fuel pump
sealing.
D.Because any crack in the seals would cause disastrous results for
astronauts.
【正确答案】
D
【答案解析】[解析] 第一段最后一句“Yet it was important to NASA because any crack in the seal could have led to destructive results for the astronauts who relied on them.”说明了答案，意为“密封圈的裂缝给依靠它的宇航员带来毁灭性的后果”。
单选题
