Where did the damage happen?
In this image released by NASA TV, the space shuttle Discovery’s robotic arm gives NASA workers a close-up view of the damage to the thermal blanket. The U.S. space agency NASA has cleared the shuttle Discovery for re-entry Monday with no need for another repair spacewalk. The crew has finished most of its work at the International Space Station and took time Thursday to remember fallen astronauts and cosmonauts.
After a mission fraught with worries about problems with Discovery’s fragile heat shield, shuttle officials say the orbiter appears safe to come back to Earth.
The last issue engineers hurried to analyze was a loose piece of thermal blanket below the cockpit window, believed torn during Discovery’s launch by debris falling off its exterior fuel tank. NASA feared that if the fabric ripped away during the high-speed descent through the atmosphere, an impact could damage Discovery’s tail or braking rudder.
选项
A、Discovery’s tail or braking rudder would be damaged.
B、The thermal blanket could not be repaired.
C、The descent speed would be too fast.
D、The shuttle was too fragile to return to the earth.
答案
A
解析
NASA fear这一关键词出现在文章后面:NASA feared that if the fabric tipped away during the highspeed descent through the atmosphere,an impact could damage Discovery’s tail or braking rudder。虽然NASA fear后面直接连接下降速度加快,但是速度加快导致的问题damage Discovery’s tail or braking rudder才是NASA真正害怕之处。所以选A,而不选C,C是干扰项,只是现象,而非结果。
