  Answer Keys and Explanations

  1.  T   见第一段。“give sth the thumbs up”为“接受“的意思。

  2.  F   见第三段。“That's still some way from proving that the theory, proposed in the mid-1990s by biophysicist Luca Turin, is correct.”意即“现在尚无法证实生物物理学家Luca在九十年代中期提出的理论是否正确。”

  3.  NG

  4.  T  见第六段“Molecules that look almost identical can smell very different — such as alcohols, which smell like spirits, and thiols, which smell like rotten eggs.”“identical”一词是“完全相同”的意思。这句话是说alcohols和thiols的分子结构看起来一样,但是它们的味道却相去甚远。

  5.  Luca Turin      文章第二,三和七段均可看出Luca的理论即人类的鼻子是通过感觉气味分子的震动来分辨气味的。

  6.  Virginia     见第四段。

  7.  tongue     见第五段“This molecular 'lock and key' process is thought to lie behind a wide range of the body's detection systems: it is how some parts of the immune system recognise invaders, for example, and how the tongue recognizes some tastes.”

  8.  the atoms       见第八段“This would explain why isotopes can smell different: their vibration frequencies are changed if the atoms are heavier.”

  9.  vibration-assisted electron tunneling     见第九段“"The question is whether this is possible in the nose," says Stoneham's colleague, Andrew Horsfield.”句中的代词“this”指句首的“vibration-assisted electron tunneling”。

  10. Andrew Horsfield 见第九段结尾。

  11.proper experimental verification 见第十三段。

  12.their computed vibrations  见第十四段。
