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

. 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.
What is false about the "clothing color" and "body heat" factors?
选项
A、The heat surrounding you helps to attract the mosquito far away.
B、The mosquito easily detects people who wear different colors from others.
C、Mosquitos like warm places.
D、The pregnant women get bitten much easier because they are warmer.
答案
A
解析
事实细节题。根据文章第四段第一句“Visual clues allow the mosquito to locate you from relatirely far away,but as she approaches,it’s your body heat that draws her in.”可知,视觉线索帮助蚊子从远处定位,但当它靠近你之后,是你的体温吸引了它。由此可知,A项错误。
