2010年9月高口上半场阅读第三篇解析

上半场阅读第三篇

第三篇文章与2004年9月S2第四篇文章非常相似。但是这两篇文章虽然题材类似（科技大类，航空航天类题材），但是今年这篇的考点却非常简单（考察的全部是factual information）！下面，让我们来看看原文，选自newscientist ,全文868字）

LIKE the space telescope he championed, astronomer Lyman Spitzer faced some perilous moments in his career. Most notably, on a July day in 1945, he happened to be in the Empire State building when a B-25 Mitchell bomber lost its way in fog and crashed into the skyscraper 14 floors above him. Seeing debris falling past the window, his curiosity got the better of him, as Robert Zimmerman recounts in his Hubble history, The Universe in a Mirror. Spitzer tried to poke his head out the window to see what was going on, but others quickly convinced him it was too dangerous.

开头讲了一则趣闻，可以直接跳过，以第二段首句的转折作为文章的第一个重点。下面的第一个题目即有关这则趣闻说明的问题。关于答案，我们要读完第二段的大致结构才会清楚。

Spitzer was not the first astronomer to dream of sending a telescope above the distorting effects of the atmosphere, but it was his tireless advocacy, in part, that led NASA to launch the Hubble Space Telescope in 1990. Initially jubilant, astronomers were soon horrified to discover that Hubble\'s 2.4-metre main mirror had been ground to the wrong shape. Although it was only off by 2.2 micrometres, this badly blurred the telescope\'s vision and made the scientists who had promised the world new images and science in exchange for $1.5 billion of public money the butt of jokes. The fiasco, inevitably dubbed "Hubble Trouble" by the press, wasn\'t helped when even the limited science the crippled Hubble could do was threatened as its gyroscopes, needed to control the orientation of the telescope, started to fail one by one.

第二段中，有一对颇有深意的文字：initially jubilant…The fiasco 从中我们可以看出本文的话题是哈勃望远镜，文章主题是通过第一段的例证反映出来的，科学家们艰苦探索不畏艰难的精神。

By 1993, as NASA prepared to launch a rescue mission, the situation looked bleak. The telescope "probably wouldn\'t have gone on for more than a year or two" without repairs, says John Grunsfeld, an astronaut who flew on the most recent Hubble servicing mission. Happily, the rescue mission was a success. Shuttle astronauts installed new instruments that corrected for the flawed mirror, and replaced the gyroscopes. Two years later, Hubble gave us the deepest ever view of the universe, peering back to an era just 1 billion years after the big bang to see the primordial building blocks that aggregated to form galaxies like our own.

第三段按照时间顺序进行了描写，黑体字部分为重点阅读处。值得注意的是，其中划线部分有一个非常细节的考点：John Grunsfeld 在这一篇文章中是一个关键人物，题中问到他参加了第几次太空任务。

The success of the 1993 servicing mission encouraged NASA to mount three more (in 1997, 1999 and 2002). Far from merely keeping the observatory alive, astronauts installed updated instruments on these missions that dramatically improved Hubble\'s power. It was "as if you took in your Chevy Nova [for repairs] and they gave you back a Lear jet," says Steven Beckwith, who from 1998 to 2005 headed the Space Telescope Science Institute (STScI) in Baltimore, Maryland, where Hubble\'s observations are planned. Along the way, in 1998, Hubble\'s measurements of supernovas in distant galaxies unexpectedly revealed that the universe is expanding at an ever-increasing pace, propelled by a mysterious entity now known as dark energy. In 2001 the space observatory also managed to make the first measurement of a chemical in the atmosphere of a planet in an alien solar system.

第四段首句明确指出The success of the 1993 servicing mission encouraged NASA to mount three more (in 1997, 1999 and 2002). 段落中按照时间顺序分别叙述了三次后续任务。在这段中，划线部分考了一个例子理解题，相当简单！答案就在上面一句话里面。

Despite its successes, Hubble\'s life looked like it would be cut short when in 2004, NASA\'s then administrator Sean O\'Keefe announced the agency would send no more servicing missions to Hubble, citing unacceptable risks to astronauts in the wake of the Columbia shuttle disaster of 2003, in which the craft exploded on re-entry, killing its crew. By this time, three of Hubble\'s gyroscopes were already broken or ailing and no one was sure how long the other three would last. Citizen petitions and an outcry among astronomers put pressure on NASA, and after a high-level panel of experts declared that another mission to Hubble would not be exceptionally risky, the agency reversed course, leading to the most recent servicing mission, in May 2009.

第五段也是要关注段首句，despite 结构既让我们回忆上文，进一步巩固了上一段一系列successes的印象，而且还将话题扭转到looked like it would be cut short。此段没有考点。

No more are planned. The remainder of the shuttle fleet that astronauts used to reach Hubble is scheduled to retire by the year\'s end. And in 2014, NASA plans to launch Hubble\'s successor, an infrared observatory called the James Webb Space Telescope, which will probe galaxies even further away and make more measurements of exoplanet atmospheres.

这一段开头讲到，没有后续任务了——即最后一个任务就是2009年五月那次。

According to Grunsfeld, now STScI\'s deputy director, plans are afoot for a robotic mission to grab Hubble when it reaches the end of its useful life, nudging it into Earth\'s atmosphere where most of it would be incinerated. Only the mirror is sturdy enough to survive the fall into an empty patch of ocean.

But let\'s not get ahead of ourselves - Hubble is far from finished. The instruments installed in May 2009, including the Wide Field Camera 3, which took this image of the Butterfly nebula, 3800 light years away, have boosted its powers yet again. It might have as much as a decade of life left even without more servicing. "It really is only reaching its full stride now, after 20 years," says Grunsfeld.

A key priority for Hubble will be to explore the origin of dark energy by probing for it at earlier times in the universe\'s history. Hubble scientist Malcolm Niedner of NASA\'s Goddard Space Flight Center in Greenbelt, Maryland, is not willing to bet on what its most important discovery will be. "More than half of the most amazing textbook-changing science to emerge from this telescope occurred in areas we couldn\'t even have dreamed of," he says. "Expect the unexpected."

文章末端末句成为最后一个题目考点，答案也很简单：哈勃望远镜的前途不可限量。
