2015年考研英语完型填空练习：human nose
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.
