REALLY? The Claim: Mosquitoes Are Attracted to Women More Than to Men
通常的看法:女性比男性招蚊子。真的是这样吗?
THE FACTS
事实
Mosquitoes find some people tastier than others. But a widespread notion is that women, to mosquitoes at least, are the sweeter sex, supposedly because estrogen is a strong attractant.
蚊子发觉一些人比其他人好吃。但是一个普遍认同的观念是:至少对蚊子来说,吸女性的血更甜,一般认为是因为雌性激素是很强的引诱物。
In reality, gender does play a role, but not in the way most people think. As one report in the Annals of Internal Medicine pointed out, men are more likely to be attacked, primarily because of their greater body size.
短语:play a role起作用,扮演角色
事实上,性别确实有关系,但是并不是以大多数人认为的方式。《内科医学年报》的一篇报告指出,男性更容易受到蚊子攻击,主要是因为男性的体型更大。
“Larger persons tend to attract more mosquitoes,” the study said, “perhaps because of their greater relative heat or carbon dioxide.”
短语:tend to 倾向做某事
这项研究显示,“体型较大的人容易招惹更多的蚊子,可能是因为体型大的人释放出相对更多的热量或二氧化碳。”
A similar effect can be seen among women. When scientists compared pregnant women with their nonpregnant counterparts in a Lancet study in 2000, they found that the pregnant women attracted twice as many mosquitoes. The study noted that the pregnant women exhaled more carbon dioxide and had higher body temperatures, allowing mosquitoes to detect them more easily.
短语:compare A with B 与..进行比较
在女性之间也能看到相似的结果。2000年进行Lancet研究时,科学家对怀孕女性和未怀孕女性进行了比较研究。科学家们发现怀孕女性吸引的蚊子是未怀孕女性的两倍。研究特别指出怀孕女性发散出更多二氧化碳且体温也更高,这使得蚊子更容易发现她们。
In addition to carbon dioxide, lactic acid is strong attractant, which is why people are attacked more when they are outside and sweating, said Dr. Clifford W. Bassett of Allergy and Asthma Care of New York.
短语:in addition to 除…之外
纽约过敏症和哮喘护理中心的Clifford W. Bassett博士说,除了二氧化碳外,乳酸也是一个很强的引诱物。这便是为什么当人们在户外和流汗的时候容易遭蚊子攻击。
“Mosquitoes can sense these chemicals off the skin from up to 30 meters away,” Dr. Bassett said. For people who react strongly to bites, he recommends insect repellent and taking a non-sedating oral antihistamine — which can lessen the itch after a bite — before spending time outdoors.
Bassett博士说:“蚊子能在30米外的地方感觉到皮肤释放出的这些化学物质。”他建议那些对蚊子叮咬反应剧烈的人们在外出前使用驱虫剂和非镇静作用的口服抗组织胺药----这可以减轻蚊虫叮咬的瘙痒感。
THE BOTTOM LINE 结论
Research suggests that men are more likely to be attacked by mosquitoes than are women.
研究表明男性比女性更容易受到蚊子的攻击。
