The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, 【C1】______this is largely because, 【C2】______animals, we stand upright. This means that our noses are【C3】______to perceiving those smells which float through the air,【C4】______the majority of smells which stick to surfaces. In fact,【C5】______, we are extremely sensitive to smells, 【C6】______we do not generally realize it. Our noses are capable of 【C7】______human smells even when these are【C8】______to far below one part in one million.
Strangely, some people find that they can smell one type of flower but not another, 【C9】______others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate【C10】______smell receptors in the nose. These receptors are the cells which sense smells and send【C11】______to the brain. However, it has been found that even people insensitive to a certain smell【C12】______can suddenly become sensitive to it when【C13】______to it often enough.
The explanation for insensitivity to smell seems to be that the brain finds it【C14】______to keep all smell receptors working all the time but can【C15】______new receptors if necessary. This may【C16】______explain why we are not usually sensitive to our own smells—we simply do not need to be. We are not【C17】______of the usual smell of our own house, but we【C18】______new smells when we visit someone else’ s. The brain finds it best to keep smell receptors【C19】______for unfamiliar and emergency signals【C20】______the smell of smoke, which might indicate the danger of fire.
【C18】
选项
A、tolerate
B、repel
C、neglect
D、notice
答案
D
解析
考查动词辨析。空格所在部分讲的是“我们察觉不到自己家里惯有的气味,但是当我们拜访其他人的家时,就会______到不熟悉的气味”。句中的“但是”告诉我们这是转折关系,因此,空格处应该填和“察觉不到”相反的词。D.notice“注意到”,符合文意。
