" [& T5 e: c& `0 i- p' z 1. T 见第一段。“give sth the thumbs up”为“接受“的意思。 / z3 N( B3 A( h1 w6 l* z
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。”

# F; k. ~8 Y6 z2 C3 r4 r 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。

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.” ' d4 E4 e4 J. W" ]
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 Y$ ?( D2 F* `- c& j2 i/ F
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”。 3 i( r/ W7 p ?0 \: W( q+ s
