　　由于雅思阅读是整项考试中考察面面的一项，所以北京新航道建议“烤鸭”童鞋们引起重视。除了做真题，还要掌握的技巧和方法。下面请看小编为同学们整理的备考材料，希望对大家有所帮助。

　　Answer Keys and Explanations

　　1.T 见段。“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。

　　学会拓展思维，让自己的雅思阅读范围在有限的材料中可以无限的扩大，不拘泥于书本，这才是制胜的法宝。北京新航道预祝大家顺利取得佳绩!
