问题    When Jack Davis, 9, looks up at the night sky, he doesn’ t see just the stars. He sees his future. The fourth grader from New Jersey has a deep interest in outer space and the alien (外星的) beings he thinks might live there.
   In July, Jack heard that NASA was looking for a new planetary protection officer and decided he was the right person for the job. The position, which focuses on preventing astronauts from accidentally bringing extremely small, potentially dangerous alien life-forms back to Earth and ensuring that astronauts do not take Earth-based germs with them into space, pays from $124, 406 to $187, 000 per year.
   Jack wrote a letter to NASA, noting his qualifications for the job. " My sister says I am an alien, " Jack wrote, pointing out that since he is young, he can "learn to think like an alien". He signed the letter "Jack Davis, Guardian of the Galaxy".
   Within days, Jack received a personal letter from NASA’ s planetary science director, James L. Green. "We are always looking for bright future scientists and engineers to help us, " Green wrote. "I hope you will study hard and do well in school. We hope to see you here at NASA one of these days!"
   Jack said he was "shocked" when Green’ s response arrived. "I shouted, I got a letter from NASA!"
   Green says he loves to answer letters from children. He calls his response a "gravity assist". Spacecraft use gravity assistance from objects like planets and moons to help power the craft toward another celestial(天上的)body. Green hopes a reply can influence a person’ s path in life in a similar way.
In his response to the boy, James Green______.
选项 A、encourages Jack to be a future NASA scientist
B、invites Jack to visit NASA as soon as possible
C、tells Jack NASA’ s requirements for scientists
D、offers to provide training for Jack at NASA
答案A
解析 细节题。根据文章第四段最后三句可知，格林的回信内容是，他们一直在寻找聪明的未来科学家和工程师来帮助他们，希望杰克能努力学习，在学校表现出色。希望有朝一日能在美国宇航局见到他。因此，选项A(鼓励杰克成为一名未来的美国宇航局科学家)符合文章意思。选项B(邀请杰克尽快参观美国宇航局)不符合文章意思。选项C(告诉杰克美国宇航局对科学家的要求)和选项D(为杰克在美国宇航局提供培训)文中均未提及。故本题选A。
