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：
