　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外语学习网

　　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。

　　14.Meanwhile，Turin is pressing ahead with his hypothesis."At Flexitral we have been designing odorants exclusively on the basis of their computed vibrations，" he says."Our success rate at odorant discovery is two orders of magnitude better than the competition." At the very least，he is putting his money where his nose is.
