14.You know the sound-that high-pitched noise in your ear that tells you a mosquito(蚊子)is looking for meal.Rather than donating blood to her cause,you wave the insect away.But that rarely works.Your body usually ends up with one or more itchy(痒的)red welts somewhere.Are there better ways to drive the annoying insects away?Yes,indeed!Preventing mosquito bites can also stop infections with dangerous illness.Mosquito-borne disease such as the Zika virus or malaria have terrible results.Several million people worldwide die from disease carried by mosquitoes each year,adding urgency to the battle.
Studies have shown that certain groups of people are easy to be bitten by mosquitoes.These include those who are pregnant,have a higher-than-normal boy temperature or have type O blood.These groups should be aware they are more attractive to mosquitoes and stay inside whenever possible,especially at dawn and dusk.Many breeds of mosquitoes are more likely to bite at these times.People should also wear light,bright colors as dark colors attract the insects.
Rubbing mosquito repellents(驱蚊剂)on exposed skin keeps the insects away for a time.Studies show that those containing DEET are most effective.Depending on the brand of repellent,the chemical keeps mosquitoes away for 5to 13hours.Some plant oils can be used instead of DEET,but they require more frequent application-every two hours-and in greater concentrations.Oils such as lemon eucalyptus or citronella are two possibilities.
Another chemical,permethrin,can be applied to clothing to ward off mosquitoes.The chemical sticks to the fabric and will last through a few washings.Clothing that has been factory-treated with the chemical is also available.The manufactures say that it will remain the permethrin for about 70 washings.
Mosquito coil(圈,卷)also keep mosquitoes away.However,the smoke from them pollutes and can damage the lungs,so they should be used with care.
When you're inside,simply plugging in some fans will keep mosquitoes away as they are weak fliers.
Everyone wants to avoid mosquito bites,so try several methods to see what works for you.

解答 56-59 CABD
56.C 考查细节理解.根据"Depending on the brand of repellent,the chemical keeps mosquitoes away for 5to 13hours"可知,化学驱虫剂可以避免蚊子叮咬5到13个小时,再根据"Some plant oils can be used instead of DEET,but they require more frequent application-every two hours-and in greater concentrations"可知,一些植物油可以使用避蚊胺,但是它们需要更频繁的使用,通常是两小时之内,且需要更大的浓度.通过对比,可以看出化学驱虫剂持续时间更长,所以去除一些化学物质是不容易的.故选C.
57.A 考查词意猜测.A.prevent from 阻止 B.take in吸收 C.break away逃跑 D.turn out结果是.本文介绍的是避免蚊子叮咬的几种方法,所以这里提到这种化学物质"permethrin氯菊酯"也是为了说明它的驱蚊效果,它可以阻止蚊子叮咬.故选A.
58.B 考查主旨大意.根据文章的结尾"Everyone wants to avoid mosquito bites,so try several methods to see what works for you",句意:每个人都想避免蚊虫叮咬,所以尝试几种方法,看看哪个适合你.可知本文讲述的是如何避免蚊虫叮咬.故选B.
59.D 考查推理判断.根据文章最后一句话"so try several methods to see what works for you",作者建议尝试几种驱蚊方法,看看适合你.可推断出,每个人所适合的驱蚊方法不一样,不同的人应该选择不同的方法来避免蚊子.故选D.
