23、译大意星期二，美国航空航天局成功宣布，奥利安（猎户座）宇宙飞船发射中止系统能（使宇航 员乘员舱）超高速驶离超速行驶的火箭，并在发射出现紧急状况时，将宇航员拉回安全地点。我们也将研发出功能同等强大的发射中止系统。若火箭在升空早期出现故障，该系统就可以 让全体宇航员脱离险境。解析根据定位句中的“pull astronauts to safety”和“pull the crew away”可知，发射中止系统的最终目 的是在紧急情况时能让宇航员脱险，确保其安全。A选项意为“测试宇宙飞船是如何适应高压的”； B选项意为“从危险的飞行中拯救宇航员的生命” ;C选项意为“让火箭比之前飞得更快”；D选项意为
24、“研究奥利安（猎户座）的难度”。故选B。2D指代判断题。定位句Its location control motor turned the capsule over end-over-end to exactly point it, and then another motor fired, releasing the crew carriage for landing in the Adantic Ocean.（第二段第三句） 国窿大意系统定位马达将太空舱首尾倒置以精准定向，接着另一个马达点火启动，使宇航员乘员舱 脱离并降落在大西洋上。解析根据定位句中的“releasing the crew
25、carriage for landing in the Adantic Ocean”可推知，点火启动 该马达，使宇航员乘员舱分离,让其降落在大西洋。A选项意为“暂停马达” ;B选项意为“加速马达”； C选项意为“定位马达” ;D选项意为“（部件）分离马达”。故选D。3D推理判断题。定位句Today, the team confirmed our abort abilities under these demanding conditions and put us one huge step closer to the first flight carrying people to the Mo
26、on and the next American Moon walkers will leave Earth aboard Orion and begin a new time of exploration.（第四段第三句）翻译大意现如今，该项目团队证实了我们（系统）在严苛条件下的中止能力,并且使我们在首次载 人月球飞行（项目）上迈出了巨大的一步，离目标更接近了。接下来的美国月球漫步者将乘坐奥利安 驶离地球,开启航天探索的新时代。解析根据第三段内容以及定位句可知，有了这项高新技术,Mark Kirasich对人类探索月球充满希 望，乐观地认为美国即将开启航天新时代。A选项意为“太空飞行既难又危险”；B选项意为“奥利安 计划不便于实施”；C选项意为“中止系统非常值得研究”；D选项意为“对月球和火星的探索即将开 始”。故选D。
