The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, __1__ this is largely because, __2__ animals, we stand upright. This means that our noses are __3__ to perceiving those smells which float through the air, __4__ the majority of smells which stick to surfaces. In fact, __5__, we are extremely sensitive to smells, __6__ we do not generally realize it. Our noses are capable of __7__ human smells even when these are __8__ to far below one part in one million.Strangely, some people find that they can smell one type of flower but not another, __9__ others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate __10__ smell receptors in the nose. These receptors are the cells which sense smells and send __11__ to the brain. However, it has been found that even people insensitive to a certain smell __12__ can suddenly become sensitive to it when __13__ to it often enough.The explanation for insensitivity to smell seems to be that brain finds it __14__ to keep all smell receptors working all the time but can __15__ new receptors if necessary. This may __16__ explain why we are not usually sensitive to our own smells we simply do not need to be. We are not __17__ of the usual smell of our own house but we __18__ new smells when we visit someone else’s. The brain finds it best to keep smell receptors __19__ for unfamiliar and emergency signals __20__ the smell of smoke, which might indicate the danger of fire.1________________[A] although[B] as[C] but[D] while

Primer on Smell In addition to bringing out1 the flavor of food, what does the sense of smell do for us ? Smell “gives us information about place, about where we are,” says Randall Reed, a Johns Hopkins University professor whose specialty is the sense of smell. ___1___ “Whether we realize it or not, we collect a lot of information about who is around us based on smell,” says Reed. Even at a distance, odors can warn us of2 trouble — spoiled food, leaking gas, or fire. “It’s a great alert,” offers Donald Leopold, a doctor at Johns Hopkins. For example, if something in the oven is burning, everyone in the house knows it. With just a simple scent, smell can also evoke very intense emotion. Let’s say, for example, that the smell is purple petunias. ___2___ Now let’s imagine that your mother died when you were three, and she used to have a flower garden. You wouldn’t need to identify the smell or to have conscious memories of your mother or her garden. You would feel sad as soon as you smelled that spicy odor. Compared with3 animals, how well do people detect smelts ? That depends on what you mean by “how well”. We are low on receptor cells : current estimates say that humans have roughly five million smell-receptor cells, about as many as a mouse. ___3___ Reed says that, across species, there is a relatively good correlation between the number of receptor cells and how strong the sense of smell is. “You can hardly find the olfactory bulb in a human brain —— it’s a pea-sized object. In a mouse, it’s a little bigger. It’s bean-sized in a rat, about the size of your little finger in a rabbit, and the size of your thumb in a bloodhound.” Does that mean that our sense of smell is not very acute ? Not exactly. While we may not have the olfactory range of other creatures, the receptors we do have are as sensitive as those of any animal. ___4___ A trained “nose”, such as that of a professional in the perfume business, can name and distinguish about 10,000 odors. Reed says that a perfume expert can sniff a modem scent that has a hundred different odorants in it, go into the lab, and list the ingredients. “In a modest amount of time, he comes back with what to you or me would smell like a perfect imitation of that perfume. It’s amazing.” What happens to4 our sense of smell as we age ? Many people continue to have good olfactory function as they get older. ___5___ Leopold says that smell is generally highest in childhood, stays the same from the teens through the 50s, and drops starting at about 60 for women and 65 for men. “The average 80-year-old is only able to smell things half as well as the average 20-year-old,” says Leopold.词汇: scent /sent/ n. 气味,香味petunia /p 'tju:ni / n. 喇叭花olfactory / l'f kt( )ri/ adj. 嗔觉的,味道的sniff /snif/ v. 嗅,闻,用力吸注释:1. bring out:使……显出,使……变得明显2. warn of:发出关于……的警告。warn sb. of sth.:警告某人某事3. compare with:与……相比4. happen to:发生于,发生在练习:A These flowers have a rich spiciness that no other petunia has.B Odors, or smells, can warn us about trouble.C That’s not the rule, however.D And smell tells us about people.E We can also think, and we make conscious (and successful) efforts to tell the difference between one smell and another.F A rat has some 10 million, a rabbit 20 million, and a bloodhound 100 million.

《Men Smell of Cheese Women of Onions》Little girls may be made of sugar all things nice, but their armpits smell of onions. ______ (1) That’s the conclusion of research in Switzerl that involved taking armpit sweat samples from 24 men 25 women after he had spent time in a sauna ridden an exercise bike f 15 minute. ______ (2) “Men smell of cheese, women of grapefruit onion,” says Christian Starkenmann of Firmenich, a company in Geneva that researches flavours perfumes f food cosmetics companies. The team found that the women's armpit sweat constrained relatively high levels of an odourless sulphur-containning compound – 5 milligrams per milliliter of sweat versus 0.5 milligrams in men. When the researchers mixed this compound in the lab with bacteria commonly found in the armpit, the bugs turned it into a thiol - a previously discovered odour from armpits that is akin to onion. “The me sulphur precurs we added, the me intense was the malodour,” says Starkenmann, whose team’s results appear in Chemical Senses. ______ (3) The men, meanwhile, had relatively high levels of an odourless fatty acid which turned into a cheesy odour when exposed to the same types of bacteria. The balance of oniony to cheesy precurss in women’s sweat made it smell wse than men’s as rated by independent smell assesss. ______ (4) “We could make inhibits that neutralise the precurss, block the bacterial enzymes that do the conversion,” says Starkenmann. Some researchers are sceptical that gender is the main deciding fact, arguing that the patterns found in Swiss volunteers might not apply to other populations with different diets genetic background. ______ (5) 词汇: armpit n. 腋(部) malodour n.难闻的气味,恶臭 grapefruit n.葡萄柚 neutralize v.中和,抵消 sulphur n.硫 enzyme n.酶 thiol n.硫醇 注释: 1. smell of onions:.....闻起来像洋葱 2. ... is akin to onion:......近似于洋葱 练习: A Bacterial enzymes turn the otherwise odourless precurs into the malodour. B And while free of slug snail odours, men’s armpits pack a powerful cheesy whiff. C Most cases of skin od is associated with break down of the compounds found in sweat by bacteria that live on the skin. D Nest; the team hope to develop new ingredients f deodants that fight the smells. E The researchers found marked differences in the sweat from men women. F “Other facts include what you eat. what you wash with, what you weat what genes you inherit,” says Tim Jacob of Cardiff University in the UK.
共用题干第一篇The Smell of MoneyFor many years large supermarkets have been encouraging us to spend money by pumping the smell of freshly-baked bread into their stores. Now Dale Air, a leading firm of aroma(香气)consultants, has been approached by Barclay's Bank to develop suitable artificial smells for their banks.Researchers have suggested that surrounding customers with the"smell of money"will encourage them to feel relaxed and optimistic and give them added confidence in the bank's security and professionalism.But before a smell can be manufactured and introduced into banks' air conditioning systems,it must be identified and chemically analyzed,and this has proved to be difficult.The problem is that banknotes and coins tend to pick up the smell of their surroundings.So cash that has been sitting in a cash register at a fishmonger's(鱼贩)will smell of fish,and banknotes used to pay for meals in restaurants will tend to smellof food.It may be a challenge,but aroma experts have little doubt that the use of artificial smells can be an effective form of subconscious advertising. Lunn Poly,a British travel company,introduced the smell of coconuts(椰 子)into its travel agencies and saw a big increase in spending by holiday makers.Many cafs now have elec-tric dispensers(自动售货机)that release the smell of freshly roasted coffee near their entrances, subtly encouraging customers to come in and have a drink or snack. Even prestigious car maker Rolls-Royce has been spraying the inside of its cars to enhance the smell of the leather seats."The sense of smell is probably the most basic and primitive of all human senses,"explains researcher Jim O'Riordan. "There is a direct pathway from the olfactory(嗅觉的)organs in the nose to the brain."It is certainly true that most people find certain smells incredibly strong,stirring memories and feelings in a way that few other stimulants(刺激物)can rival. It is a phenomenon marketing consultants have long recog- nized,but until recently have been unable to harness."We've made great progress but the technology of odour production is still in its infancy,"says O'Riordan."Who knows where it will take us."Researchers believe that introducing the"smell of money"into banks will encourage people_________.A:to spend moneyB:to feel confident about banksC:to earn more moneyD:to withdraw money from banks
