世界節(jié)假日博覽 第83期:全國(guó)嗅覺日

National Sense of Smell Day is an annual event sponsored by the Sense of Smell Institute. It is an American holiday that takes place every year on the last Saturday of April. Many different events are organized at children’s museums and science centers across the country. There are usually many hands-on (or nose-on) activities for children to do to learn about the sense of smell. Activities can include finding out about different smells from around the world and remembering the smells from your childhood. The aim of the day is to raise awareness of how important the sense of smell is. We rarely think about how useful it is to be able to smell, and how it helps us survive in our lives.
每年，全國(guó)都會(huì)舉辦“嗅覺日”活動(dòng)，“全國(guó)嗅覺日”由嗅覺協(xié)會(huì)發(fā)起。每年4月份的最后一個(gè)周六為美國(guó)嗅覺日。各地兒童博物館，科技中心都會(huì)舉辦活動(dòng)。兒童通常能夠親自動(dòng)手，或是直接用鼻子來(lái)感受嗅覺?；顒?dòng)包含發(fā)現(xiàn)世界的不同味道，回憶兒時(shí)味道。該節(jié)日的設(shè)立目的是讓人們提高對(duì)嗅覺的重視程度。對(duì)于嗅覺的有用性，對(duì)人類生存的重要性，我們卻從未想過。


How important is your sense of smell to you? Most people say it is the least important of our five senses. Humans generally have a poor sense of smell. Dogs have noses that are up to one-hundred-million times more sensitive than ours. However, we can smell thousands of different things, whereas we can only separate taste into five different tastes. Most of us have a normal sense of smell, but some people have problems smelling. People who suffer from anosmia cannot smell at all, while people who have hyperosmia are very, very sensitive to smells. An unusual disorder is dysosmia things smell differently than they should. Perhaps chocolate smells like gasoline and roses smell like the sea.
嗅覺到底有多重要？絕大多數(shù)人認(rèn)為，它是五感中最不起眼的一個(gè)。通常，人類的嗅覺靈敏度不高。狗的嗅覺靈敏度是人的100萬(wàn)倍。然而，人類仍然可以通過嗅覺來(lái)判斷數(shù)千種物品，但我們只把味道分為5種。多數(shù)人的嗅覺水平正常，但還有一些人存在嗅覺障礙。患有嗅覺缺失癥的患者無(wú)法對(duì)味道做出判斷，而對(duì)于患有嗅覺過敏癥的患者，他們對(duì)嗅覺卻異常敏感。還有嗅覺障礙癥患者，他們對(duì)味道的感知異于常人?；蛟S巧克力聞起來(lái)像汽油，玫瑰聞起來(lái)像茶葉。
