Question

After an extra day in space,the crew of Discovery returned to Earth,landing at Edwards Air Force Base in California early on Tuesday morning.The shuttle and its crew spent two weeks in space,most of it aboard the International Space Station.It was the first flight of NASA's space?shuttle fleet since February 2003,when the shuttle Columbia came apart while re?entering Earth's atmosphere.?
NASA officials delayed Discovery's return for one day because of cloudy weather in Florida,where the shuttle was supposed to lanD. On Tuesday morning,mission controllers ?directed? Discovery to a landing site in California,where the skies were clear.The crew members will have to wait until Wednesday to see their families when they all meet together in Houston at the Johnson Space Center.?
Discovery had a very busy mission in space,compared to past missions.The space shuttle docked with the International Space Station most of the journey,delivering badly needed ?supplies? and repairing damaged parts.The crew spent a lot of time testing new repair techniques on their own shuttle,conducting three different spacewalks(where astronauts exit the space shuttle to do work outside).On the third spacewalk,astronaut Steve Robinson went underneath the shuttle to remove material sticking out from between the spacecraft's ?protective? tiles.?
There were concerns in the last remaining days of Discovery's mission that a torn heat blanket—another shield against overheating in the space shuttle—may pose a problem to crew members. NASA officials and technicians worked on ways that the crew could fix the problem, but later decided it was not a risk.?
With the shuttle and its crew safely back on firm ground, NASA is hailing this mission, labeled STS?114,as a huge success. “I hope this shows people that we're coming back,” NASA spaceflight chief Bill Readdy said after Discovery's successful landing. “We've got some more work to do. We know what we need to do and we'll do it.?

1.　细节归纳题。根据第三段第二句和第三句话可知:寻找“哥伦比亚号”航天飞机解体的原因不在其例。?
2.　推测题。根据第二段第一句反推可知:要不是天气原因,“发现号”航天飞机会早一天降落在佛罗里达州。?
3.推测题。根据短文第一段第二句话和第三段第二句话可知:“发现号”航天飞机此次飞行的两个星期中绝大部分时间是停靠在国际空间站上。由此推断“九天”最可能。?
4.主旨题。根据短文首句“the crew of Discovery returned to Earth”及全文意思用“Welcome Back, Discovery（发现号,欢迎你凯旋归来）”最能概括全文。
