9.Flying is the safest way to travel…or is it?Some doctors think the aeroplane is a dangerous place,especially for the old and the unhealthy.
Although the aeroplane is the pressurized,there is less oxygen than on the ground.Anyone with heart disease or a lung problem notices the difference much sooner.Even the healthy people find it difficult to concentrate after hours of breathing less oxygen than usual.So anyone who has had a heart attack should not fly for at least two weeks after the attack.
Because of changes of pressure,pregnant women shouldn't take a flight lasting four hours after their thirty-fifth week or a short flight after 36weeks.People with bad colds will probably get earache during take-off and landing.
Even if you feel well when you get on the plane,you will possibly feel ill when you get off.Sitting on the plane for hours-especially in economy class where there isn't very much leg room-gives anyone aches and pains.Most of the air you breathe is recycled so you will possibly catch a cold or flu from one of the other passengers.
Flying also causes dehydration.Everyone needs to drink more in the air,but you shouldn't drink alcohol because it makes you even more thirsty.
The most common problem is jet lag.But there isn't much you can do to prevent it.You should change to your new time zones as soon as possible and you shouldn't sleep if it's still daylight.
Crowded airport,long queues and delays cause stress and high blood pressure.So,be careful!Flying is the safest way to travel,but is it the healthiest?

分析 本文屬于說(shuō)明文閱讀,作者通過(guò)這篇文章主要向我們描述了飛行雖然是最安全的旅行方式,但不是最健康的,病人不適合飛行,健康人在長(zhǎng)時(shí)間飛行中也會(huì)感到不適.
解答 63.B.詞義猜測(cè)題.根據(jù)第四段"Flying also causes dehydration.Everyone needs to drink more in the air"飛行也會(huì)導(dǎo)致脫水,每個(gè)人都需要在空氣中多喝水;可知意為脫水;故選B.
64.C.細(xì)節(jié)理解題.根據(jù)第二段:Anyone with heart disease or a lung problem notices the difference much sooner可知航班上患有心臟病的乘客比健康人更早感到壓力;故選C.
65.A.細(xì)節(jié)理解題.根據(jù)第二段第三段可知坐在飛機(jī)上,你可能有呼吸不暢,耳痛,口渴等癥狀;故選A.
