雅思阅读练习及答案：

Rogue theory of smell gets a boost（2）

11. The UCL team calculated the rates of electron hopping in a nose receptor that has anodorant molecule bound to it. This rate depends on various properties of the biomolecularsystem that are not known, but the researchers could estimate these parameters based ontypical values for molecules of this sort.

12. The key issue is whether the hopping rate with the odorant in place is significantlygreater than that without it. The calculations show that it is — which means that odouridentification in this way seems theoretically possible.

13. But Horsfield stresses that that’s different from a proof of Turin’s idea. "So far thingslook plausible, but we need proper experimental verification. We’re beginning to think aboutwhat experiments could be performed."

14. Meanwhile, Turin is pressing ahead with his hypothesis. "At Flexitral we have beendesigning odorants exclusively on the basis of their computed vibrations," he says. "Oursuccess 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.

Questions 1-4

Do the following statements agree with theinformation given in the passage? Please write

TRUE if the statement agrees with the writer

FALSE if the statement does not agree with thewriter

NOT GIVEN if there is no information about thisin the passage

1. The result of the study at UCL agrees withTurin’s theory.

2. The study at UCL could conclusively prove what Luca Turin has hypothesized.

3. Turin left his post at UCL and started his own business because his theory was ignored.

4. The molecules of alcohols and those of thiols look alike.

Questions 5-9

Complete the sentences below with words from the passage. Use NO MORE THAN THREEWORDS for each answer.

5. The hypothesis that we smell by sensing the molecular vibration was made by ______.

6. Turin’s company is based in ______.

7. Most scientists believed that our nose works in the same way as our ______.

8. Different isotopes can smell different when ______ weigh differently.

9. According to Audrew Horsfield, it is still to be proved that ______ could really occur inhuman nose.

Question 10-12

Answer the questions below using NO MORE THAN THREE WORDS from the passage foreach answer.

10. What’s the name of the researcher who collaborated with Stoneham?

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 fromproving that the theory, proposed in the mid-1990sby 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 almostidentical can smell very different — such as alcohols, which smell like spirits, and thiols, whichsmell 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 widerange of the body’s detection systems: it is how some parts of the immune system recogniseinvaders, 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 vibrationfrequencies are changed if the atoms are heavier.”

9. vibration-assisted electron tunneling 见第九段“"The question is whether this is possible inthe 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。
