[1]画线部分在句中作状语。其中“how arduous...it was”为宾语从句，作第一个of的宾语；“that could go wrong”为that引导的定语从句，修饰the many things。 [2]画线部分为what引导的主语从句，what在从句中作主语。 [3]画线部分为过去分词结构作让步状语。其中“that was...school students”为that引导的定语从句；much修饰形容词的比较级。“used by...students”为过去分词短语作后置定语，修饰the ones。 2 Following the Moon landings, space travel rapidly became unexceptional⑩ to the public, as innovations⑪ succeeded each other⑫. [4]By the early 1980s, the great rockets previously used in the American space programme had been replaced by the space shuttle⑬.When the Challenger space shuttle took off on 28 January 1986, the world seemed to have lost its wonder at the amazing achievements of the astronauts involved.But this was going to be no ordinary excursion⑭， and millions of people tuned in ⑮to witness⑯ the take­off on TV.It was special because Christa McAuliffe aged 37, an ordinary teacher and mother, was about to become the first civilian⑰ in space. She planned to give two 15­minute lessons from orbit: the first to demonstrate⑱ the controls of the spacecraft and explain how gravity⑲ worked，and the second to describe the objectives ⑳of the Challenger programme[5]．Christa hoped to communicateeq \o(○,\s\up3(21)) a sense of excitement and rekindleeq \o(○,\s\up3(22)) interest in the space programme.With the eyes of students across the nation upon her, she might have inspired [6]an entirely new generation of astronauts and space scientists. [4]本句为主从复合句。“Following the Moon landings”为现在分词短语作状语；as引导原因状语从句，as意为“因为，由于”。 [5]画线部分中的“to demonstrate...worked”和“to describe programme”均为不定式短语作后置定语，分别修饰the first和the second。 [6]画线部分属于“might have done”结构，用于表示过去应该做而没做的事。 3 Tragicallyeq \o(○,\s\up3(23))， she never returned to her classroom as the shuttle exploded just over a minute after taking off in Florida, and all seven astronauts on board were killed.The world went into shockeq \o(○,\s\up3(24))， most people having assumedeq \o(○,\s\up3(25)) that this space flight would be no more dangerous than travelling in an aeroplane[7]．How wrong they had been! Instantaneouslyeq \o(○,\s\up3(26))， excitement and optimism turned into terroreq \o(○,\s\up3(27)) and failure.It was the most disastrous space accident ever，and it cast a shadow oneq \o(○,\s\up3(28)) people's hearts. [7]画线部分为独立主格结构，在句中作状语，most people是其逻辑主语。 4 “I can remember that day so clearly, watching the take­off on TV at school，”said one student.“There was an ordinary teacher on the Challenger，and we were all very excited.We didn't have much patience waiting for the launch.We had seen the smiling faces of the astronauts waving to the world as they stepped into the shuttle. [8]Then, little more than a minute after take­off, we saw a strange red and orange light in the sky, followed by a cloud ofeq \o(○,\s\up3(29)) white smoke.The Challenger had exploded in mid­aireq \o(○,\s\up3(30)) and we all started screamingeq \o(○,\s\up3(31)).” [8]本句为主从复合句。as引导时间状语从句，“waving to the world”为现在分词短语作后置定语，修饰the astronauts。 5 Following the shock of the Challenger disaster, space shuttle flights were suspendedeq \o(○,\s\up3(32)) for nearly three years while the cause of the disaster was investigated, and some of the shuttle's componentseq \o(○,\s\up3(33)) were redesigned.But there was never any doubt that [9]manned flights would continue，and on 29 September 1988, the space shuttle programme resumedeq \o(○,\s\up3(34)) with the successful launch of Discovery. [9]画线部分属于“there is/was no doubt that...”句型，意为“毫无疑问……”。 6 It has now been over 30 years since the loss of Challenger and although the lives of its creweq \o(○,\s\up3(35)) were cut tragically shorteq \o(○,\s\up3(36))， they take their placeeq \o(○,\s\up3(37)) alongside the other heroes of space exploration, such as Gagarin, Tereshkova, Armstrong and Yang Liwei.The memory of those seven will live forever, written in the stars, inspiring us to join them in humanity's greatest journey of exploration and discovery.The sacrificeeq \o(○,\s\up3(38)) of the Challenger calls to us, reminding us that we must continue to reach for the stars, no matter how distant they might seem[10]． [10]画线部分为现在分词结构作状语。其中that引导宾语从句，在从句中no matter how引导让步状语从句。 参考译文 “挑战者”的呼唤 1．自从1969年7月20日尼尔·阿姆斯特朗首次登月以来，人们已习惯于太空旅行这个概念。数百万人在黑白电视机前观看了首次登月，为此激动得心都跳到了嗓子眼儿，因为大家都明白这是一项多么艰难、多么危险的任务，许多地方都可能出错。伴随着阿姆斯特朗说出那句名言——“这是个人的一小步，却是人类的一大步”，曾被认为是不可能的事情如今已经实现了。执行“阿波罗 11”号任务的三位宇航员在一台计算机的指导下都安全返回地球，这台计算机远不如当今普通学校的学生使用的计算机功能强大。 2．登月后，随着新事物接连出现，宇宙航行迅速成为公众眼中的寻常之事。20世纪80年代早期，美国太空计划中使用的大型火箭已被航天飞机所代替。当“挑战者”号航天飞机于1986年1月28日发射时，对于宇航员所获得的令人惊叹的成就，全世界似乎已经失去了新鲜感。然而这将不是一次普通的航行，数百万人打开电视，共同见证这次发射。这次航行的特殊之处在于一位37岁名为克丽斯塔·麦考利夫的普通教师兼母亲将会成为第一位到访太空的普通公民。她计划在“挑战者”号沿轨道运行时讲两节课，每节15分钟。第一节课要展示航天器的操控装置，并解释一下引力是如何发挥作用的； 第二节课要讲述“挑战者”号太空计划的目的。克丽斯塔希望借此传达她的激动之情，重新燃起人们对太空计划的兴趣。当全国学生的目光都聚集在她身上时，她或许能激发他们成为新一代宇航员和太空科学家的理想。 3．令人悲痛的是，她再也没能回到她的课堂。航天飞机在佛罗里达州发射仅一分多钟后就发生了爆炸，机上七名宇航员全部牺牲。全世界都震惊了！大多数人本以为这次太空航行不会比乘飞机旅行更加危险，但是所有人都大错特错了！激动和乐观瞬间化为恐惧和挫败，这是有史以来最惨烈的航天事故，给人们心里蒙上了阴影。 4．一个学生回忆道∶“我非常清楚地记得那天，我在学校通过电视观看发射场景。有位普通教师在‘挑战者’号上，我们都非常激动，迫不及待地等着发射。我们看到宇航员笑容满面，向世界挥手致意，步入航天飞机。然后，发射仅仅一分多钟后，我们就看到空中奇异的红色和橙色的光芒，紧接着是一大团白烟。‘挑战者’号在半空中爆炸了，我们都开始尖叫。” 5．“挑战者”号令人震惊的灾难发生后，航天飞机航行中止了近三年时间，同时调查事故原因，重新设计飞行器的部分零件。但是毫无疑问，载人飞行绝不会就此停止。1988年9月29日，随着“发现”号的成功发射，航天飞机项目重新启动。 6．“挑战者”号失事至今已有30多年了。虽然“挑战者”号的机组人员英年早逝，但他们与加加林、捷列什科娃、阿姆斯特朗和杨利伟等进行太空探索的英雄们一道，都在历史上占有一席之地。他们七位的事迹将永存于世，书写在漫天星辰中，激励我们加入他们，共向致力于人类最伟大的探索发现之旅。“挑战者”号的牺牲召唤着、提醒着我们，不管星空看起来多么遥不可及，我们都要持之以恒地去探索。 Ⅰ.Reading for main idea Read the passage quickly and choose the best answer.
