Which of these animals hibernates in winter? Tree squirrel, mosquito, monarch butterfly or silverfish. Mosquitoes are the only animals on this list that enter diapause, a hibernation-like period of shutting down for the cold winter months.

下列哪种动物会在冬天冬眠?松鼠、蚊子、帝王蝶还是衣鱼?蚊子是上述名单中唯一会进入滞育期的动物,滞育期与冬眠类似,即在寒冷的冬季停止活动。

So that explains why the pesky pests always come back in the summer, and when they do, why do they always seem to bite some people more often than others? Scientists say there are a number of things mosquitoes are attracted to. Strongly scented soaps are believed to get their attention along with certain deodorants and perfume. The increased carbon dioxide we give off when we're exercising can create a buzz among the insects, as well as our sweat. As far as clothing goes, researchers are divided over whether it's bright or dark clothes that make us easier for mosquitoes to spot but a recent study has found that different types of body odor could make some people more prone to mosquito bites than others.

这也解释了这种令人讨厌的害虫总是在夏季出现的原因,而那时,为什么与其他人相比,有些人总是更容易被蚊子叮咬?科学家表示,蚊子会被一些事情吸引。据信,香味浓郁的香皂、某些除臭剂和香水会引来蚊子。我们在锻炼时会释放出更多的二氧化碳,增加的二氧化碳和我们的汗水也会吸引蚊子。至于亮色衣服还是深色衣服会使我们更容易成为蚊子的目标,研究人员意见不一,不过最近的一项研究发现,不同类型的狐臭可能令一些人比他人更易被蚊子叮咬。

Is there anything that could be done about that? Maybe one day if a drug is designed that can change those odors. Could that have side effects of its own? Yes, but because of the diseases they carry mosquitoes are responsible for more human deaths than any other animal.

有没有解决方法?也许有一天会有药物能改变这些臭味。这是否会有副作用?会,但由于蚊子会携带疾病,因此其引发的死亡人数比其他任何动物都要多。
