  • 第3题:

    We live in a moment packed with new possibilities,and we've never been better equipped to seize them.The problem is that many of us don't feel it.If this is the best time to be alive,it certainly hasn't becn the easiest.This upheaval has created winners:among owners ofcapital;among entrepreneurs who have grown into new markets;and among individuals whose skills,acumen or luck helps them to navigate this tangle.But it has also created losers:among pensioners and homeowners whose savings were destroyed by unforeseen financial risks;among workers whose jobs are now being done overseas by people escaping from poverty;among those whose jobs stayed onshore but are being replaced by machines;among farmers whose crops are failing because of climate change;among citizens in countries where a small elite are siphoning the benefits of global integration into offshore bank accounts.


    答案:
    解析:
    我们生活的当下充满新的可能性,我们也拥有前所未有的能力去把握这种可能性,问题是我们很多人并没有感受到它。如果说当下是最美好的时代,那一定还不是最轻松的时代。这场变革创造了成功者:有的是资本所有者;有的是开拓新市场的企业家;有的是技艺超群、机敏精干,或者好运加身的弄潮儿。但这场变革也产生了失败者:有的退休者和房主突遭金融风险,积蓄毁于一旦;有的人被国外脱贫者所取代,工作流出了国门;有的人的工作虽未流出国门,却被机器取而代之;有的农民因气候变化收成惨淡;有的人生活的国家,全球一体化的收益被少数精英收入囊中转至境外的银行账户。

    Where did Columbus first set foot on the New Continent?
    A

    Watling Island.

    B

    At the spot where a carved stone was erected to mark the event.

    C

    Somewhere in eastern Bahamas.

    D

    No consensus has been reached on the event among historians.


    正确答案: A
    解析:
    观点态度的找寻和判断。关于哥伦布于何时首次踏上新大陆,录音中首先指出历史学家Samuel Elliot Morrison已对此做出定论,但接着讲话者表示对于Morrison教授来说这个问题是解决了,“it was not for numerous other people on nautical history”,可知对于其他一些研究航海史的学者们来说,情况并非如此。由此可见,历史学家们并未就该事件达成一致意见。因此选项D为正确答案。
    【录音原文】
    The orthodox explanation of where Columbus first landed was carved in textbook stone more than 40 years ago by the dean of Columbus historians, Samuel Elliot Morrison. Morrison declared incontrovertible the evidence that Columbus first set foot on Watling Island in the eastern Bahamas. But if the question were closed for Professor Morrison, now dead, it was not for numerous other people on nautical history.

  • 第18题:

    问答题
    The approximately 65,000 images the Surveyor orbiter has beamed home in the nearly three years it has been circling Mars are full of this kind of expected hydro-scarring. But some of the pictures took scientists by surprise. The older a formation is, the more likely it is to have been distorted over the eons--smoothed by periodic windstorms or gouged by the occasional incoming meteor. However, a few of the newly discovered water channels look flesh. That discovery has lead astonished researchers to conclude that these channels may have been recently formed. Paleontologists have long assumed that if underground water was going to bubble up on Mars, it would have to be somewhere in the balmy equatorial zones, where temperatures at noon in midsummer may reach 68 degrees Fahrenheit (20 degrees Centigrade). Almost all the new channels, however, were discovered at the planet’s relative extremes--north of 30 degrees north latitude and south of 30 degrees south latitude--and all were carved on the cold, shaded sides of slopes.

    正确答案:
    “探测者号”飞船在环绕火星飞行的近三年时间里传回了大约65000张图片,这些图片上满是人们预想的那种水痕。但有些图片着实让科学家们吃了一惊。一种构造越是古老,就越有可能经过了亘古岁月的扭曲——或者被周期性而来的风暴抚平,或者被偶尔从天而降的流星凿成一个个深洞。然而,有几个新发现的水渠看起来像是新近形成的。这一发现导致惊愕不已的研究人员因此得出结论:这沟渠可能是最近形成的。行星研究科学家们一直认为,如果地下水是从火星的地表下冒出来的,它可能是在温暖潮湿的赤道地区,那里的气温在仲夏正午时候能高达华氏68度(摄氏20度)。然而,几乎所有这些新的沟渠都是在火星偏向两极的地方发现的——北纬30度以北,南纬30度以南——而且所有这些痕迹都刻在寒冷的山坡背阴处。
