雅思閱讀三大難點(diǎn)及其攻破策略

雅思考試的四大科目，容易拿分的其實(shí)應(yīng)該是閱讀部分。今天小編給大家?guī)砹搜潘奸喿x三大難點(diǎn)及其攻破策略,希望能夠幫助到大家，下面小編就和大家分享，來欣賞一下吧

雅思閱讀三大難點(diǎn)及其攻破策略

單詞難點(diǎn)

閱讀文章中涉及詞匯7000左右，但具備4000左右即可應(yīng)考。單詞量不夠的考生，應(yīng)在短期內(nèi)迅速擴(kuò)充認(rèn)知詞匯，為看文章做題打下一個良好的基礎(chǔ)。有些考生脫離語境孤立地背單詞，這樣容易遺忘或混淆單詞的意義。記憶單詞，考生可以通過制作單詞卡片，正面寫英文拼寫，背面寫中文釋義的方法來記憶。每天背一定量的生詞，并不斷補(bǔ)充，而且還可以打亂次序。當(dāng)然，最有效的是在上下文，即文章當(dāng)中記憶單詞，在文章中，每個單詞都是有語境的，在一定的語境下記單詞會更牢固，而且也知道如何用單詞。

長句難點(diǎn)

雅思閱讀考試中，有的題目考的是對于文章中某一句子的理解，若考生領(lǐng)會有偏差，就容易失分。另一方面，雅思閱讀文章中有許多長難句，考生對此不理解，導(dǎo)致考生對全篇文章的理解有誤，那么幾個小題的錯誤率將大大提高。生應(yīng)對一些復(fù)合句，尤其是雙重否定句、比較句、指代句等有一定的了解。在遇到比較復(fù)雜的句子的時候，應(yīng)靜下心來，從把握句子主干一一主謂結(jié)構(gòu)著手來分析句子結(jié)構(gòu)。一個再難的句子，將其除主干部分剔除，把握主干部分表意，那么理解文章就不成問題了。但是，如何把握長難句主干，確實(shí)需要考生練習(xí)的，考生可以從語法方面下手。

速度難點(diǎn)

雅思閱讀部分，時間到底有多緊迫，相信各位考生是有所體會的。提高閱讀速度是每一位考生必須要做的。但是，閱讀速度的改善不容易一蹴而就，需要大量的練習(xí)和長時間的努力?？忌荒芮笏俣刃那卸プ呤裁赐衢T邪道，最后成績反倒更低?？忌莆找恍╅喿x技巧，革除一些壞習(xí)慣，例如邊看文章邊讀出聲來、一次只看一個單詞、遇生詞就停下去查字典等，將有助于看文章時加快速度，快速閱讀最關(guān)鍵的是在掃描文章的時候把握段落的主旨，并做出標(biāo)記，并且在看完文章后對文章的結(jié)構(gòu)有大致的了解。

How shops can exploit people’s herd mentality to increase sales

1. A TRIP to the supermarket may not seem like an exercise in psychological warfare—but it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (that is， how ants， bees or any social animal， including humans， behave in a crowd) can be used to influence what people buy.

2. At a recent conference on the simulation of adaptive behaviour in Rome， Zeeshan-ul-hassan Usmani， a computer scientist from the Florida Institute of Technology， described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted： for instance， by placing everyday items such as milk and eggs at the back of the store， forcing shoppers to walk past other tempting goods to reach them. Mr Usmani and Ronaldo Menezes， also of the Florida Institute of Technology， set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that， if a certain product is seen to be popular， shoppers are likely to choose it too. The challenge is to keep customers informed about what others are buying.

3. Enter smart-cart technology. In Mr Usmani’s supermarket every product has a radio frequency identification tag， a sort of barcode that uses radio waves to transmit information， and every trolley has a scanner that reads this information and relays it to a central computer. As a customer walks past a shelf of goods， a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high， he is more likely to select it too.

4. Mr Usmani’s “swarm-moves” model appeals to supermarkets because it increases sales without the need to give people discounts. And it gives shoppers the satisfaction of knowing that they bought the “right” product—that is， the one everyone else bought. The model has not yet been tested widely in the real world， mainly because radio frequency identification technology is new and has only been installed experimentally in some supermarkets. But Mr Usmani says that both Wal-Mart in America and Tesco in Britain are interested in his work， and testing will get under way in the spring.

5. Another recent study on the power of social influence indicates that sales could， indeed， be boosted in this way. Matthew Salganik of Columbia University in New York and his colleagues have described creating an artificial music market in which some 14，000 people downloaded previously unknown songs. The researchers found that when people could see the songs ranked by how many times they had been downloaded， they followed the crowd. When the songs were not ordered by rank， but the number of times they had been downloaded was displayed， the effect of social influence was still there but was less pronounced. People thus follow the herd when it is easy for them to do so.

6. In Japan a chain of convenience shops called RanKing RanQueen has been ordering its products according to sales data from department stores and research companies. The shops sell only the most popular items in each product category， and the rankings are updated weekly. Icosystem， a company in Cambridge， Massachusetts， also aims to exploit knowledge of social networking to improve sales.

7. And the psychology that works in physical stores is just as potent on the internet. Online retailers such as Amazon are adept at telling shoppers which products are popular with like-minded consumers. Even in the privacy of your home， you can still be part of the swarm.

ogue theory of smell gets a boost

1.　　A controversial theory of how we smell, which claims that our fine sense of odour depends on quantum mechanics, has been given the thumbs up by a team of physicists.

2.　　Calculations by researchers at University College London (UCL) show that the idea that we smell odour molecules by sensing their molecular vibrations makes sense in terms of the physics involved.

3.　　That's still some way from proving that the theory, proposed in the mid-1990s by biophysicist Luca Turin, is correct. But it should make other scientists take the idea more seriously.

4.　　"This is a big step forward," says Turin, who has now set up his own perfume company Flexitral in Virginia. He says that since he published his theory, "it has been ignored rather than criticized."

5.　　Most scientists have assumed that our sense of smell depends on receptors in the nose detecting the shape of incoming molecules, which triggers a signal to the brain. 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.

6.　　But Turin argued that smell doesn't seem to fit this picture very well. Molecules that look almost identical can smell very different — such as alcohols, which smell like spirits, and thiols, which smell like rotten eggs. And molecules with very different structures can smell similar. Most strikingly, some molecules can smell different — to animals, if not necessarily to humans — simply because they contain different isotopes (atoms that are chemically identical but have a different mass).

7.　　Turin's explanation for these smelly facts invokes the idea that the smell signal in olfactory receptor proteins is triggered not by an odour molecule's shape, but by its vibrations, which can enourage an electron to jump between two parts of the receptor in a quantum-mechanical process called tunnelling. This electron movement could initiate the smell signal being sent to the brain.

8.　　This would explain why isotopes can smell different: their vibration frequencies are changed if the atoms are heavier. Turin's mechanism, says Marshall Stoneham of the UCL team, is more like swipe-card identification than a key fitting a lock.

9.　　Vibration-assisted electron tunnelling can undoubtedly occur — it is used in an experimental technique for measuring molecular vibrations. "The question is whether this is possible in the nose," says Stoneham's colleague, Andrew Horsfield.

10.　Stoneham says that when he first heard about Turin's idea, while Turin was himself based at UCL, "I didn't believe it". But, he adds, "because it was an interesting idea, I thought I should prove it couldn't work. I did some simple calculations, and only then began to feel Luca could be right." Now Stoneham and his co-workers have done the job more thoroughly, in a paper soon to be published in Physical Review Letters.

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

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

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

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.
