2015年新版职称英语教材新增文章系列之综合类 补全短文 第十二篇Men Smell of Cheese and Women of Onions 　　Little girls may be made of sugar and all things nice, but their armpits smell of onions. ____1____ That’s the conclusion of research in Switzerland that involved taking armpit sweat samples from 24 men and 25 women after he had spent time in a sauna or ridden an exercise bike for 15 minute. 　　____2____ “Men smell of cheese, and women of grapefruit or onion,” says Christian Starkenmann of Firmenich, a company in Geneva that researches flavours and perfumes for food and cosmetics companies. 　　The team found that the womens 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 more sulphur precursor we added, the more 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 precursors in women’s sweat made it smell worse than men’s as rated by independent smell assessors. 　　____4____ “We could make inhibitors that neutralise the precursors, or block the bacterial enzymes that do the conversion,” says Starkenmann. 　　Some researchers are sceptical that gender is the main deciding factor, arguing that the patterns found in Swiss volunteers might not apply to other populations with different diets and 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 othe
