By "some people" I mean me. Why is it that an evening stroll(散步)leaves me feeling eaten alive while my companions are left blissfully un-bitten?
Studies suggest that about 20 percent of people are "high attractor types" who are especially appealing to the female mosquitoes(蚊子)seeking out blood for the extra protein(蛋白质)they need to lay eggs. Of course, not all mosquitoes are the same. But let’ s consider some of the more general properties that affect your mosquito appeal.
Clothing Color
It’s true, mosquitoes have discerning(有辨识能力的)fashion taste. Or at least, they’re more likely to spot you as a target if you stand out from your environment. Dark colors, especially, will attract more of the insect.
Body Heat
Visual clues allow the mosquito to locate you from relatively far away, but as she approaches, it’ s your body heat that draws her in. This puts pregnant women, who average about 1.26 degrees Fahrenheit(华氏温度)warmer than others, at a particular risk—a fact which has been substantiated(证实)by a number of studies.
Carbon Dioxide
This is another reason pregnant women are at a disadvantage. Mosquitoes can detect carbon dioxide using a special organ called a maxillary palp(下颚须)from as far as 164 feet away. Unfortunately for mothers-to-be, pregnancy causes women to emit 21 percent more CO
2
. This is also why kids are often safe from bites, when bigger, more CO
2
-emitting adults are around.
Alcohol Intake
On the flip side(另一方面), pregnant women are(presumably)avoiding another mosquito attractor: alcohol. Although it’ s unclear how mosquitoes go about detecting the presence of ethanol(乙醇), studies show that drinking even just 12 ounces of beer will significantly increase the attention you receive from the pests.
The Properties of Your Skin and Sweat
(71)
Up to 85 percent of your susceptibility(敏感性)to mosquito bites has nothing to do with what you’ re drinking, wearing or how much heat your body emits—it’ s just genetic. Specifically, the composition of your skin bacteria—the kind that naturally and healthily exists there—can serve as an attractor.
Blood Type
Another factor you can’ t control? Your blood type. And it stands to reason that, if the mosquito is there to suck your blood, she cares what kind she’ s getting. People with blood type O are more prone to mosquito bites than those with type B, with type A folks bringing up the rear.
Which statement is NOT true according to the author?
选项
A、People with blood type A are more attractive than those with type O.
B、Take baths more often lower the risks of mosquito biting.
C、Kids get less bites because they emit less CO
2
.
D、The author is among the "high attractor types".
答案
A
解析
事实细节题。由皮肤和汗的特性影响对蚊子的吸引可以看出,洗澡会影响皮肤的环境,从而影响对蚊子的吸引,故B项正确。从第五段末句“This is also why kids are often safe from bites,when bigger,more CO
2
-emitting adults are around.”可知,C项正确。从开头的表述可以看出作者比其他人更容易被蚊子咬,故D项正确。由最后一段可知,O型血的人比A型或B型血的人更易受蚊虫叮咬,故A项错误。故选A。
