　　托福考試閱讀：A Pain in Third Class

　　有一種叫“經濟艙綜合癥”的病，估計很多人第一次聽說。如果人在狹窄的空間長時間坐著不動，比如乘坐飛機時，腿一直彎曲著，結果會使腿部后側靜脈的血流速度降低，并在小腿深靜脈中形成血凝，如血凝塊脫落，順著血流到達肺部，并在肺部形成栓塞即肺栓塞，可能會引起猝死，這就是“經濟艙綜合癥”：一種久坐不動能致人命的病。據世界衛生組織估計，長途飛行旅客中此危險發生的幾率為1/6000，這就意味著1個運載300名乘客的航班，每長途飛行20次就會有1位乘客發生“經濟艙綜合癥”。實際上，專家認為，只要保持一個坐勢，腿一直彎曲著，不活動超過4個小時，那么，發生深靜脈血栓栓塞即“經濟艙綜合癥”的危險將會明顯增加。而現在，坐車的人，長時間坐著工作的人，在電腦前一坐就是半天的人，比乘坐飛機的人要多得多，“經濟艙綜合癥”將會威脅著更多久坐的人。

　　It seems the more (1)cramped(狹窄的，擁擠的) your airplane seat is, the longer the flight always takes. Some folks handle this situation by just sitting tight(繃緊的) for the entire duration(持續，期間), dreaming of the hour when the plane finally lands and they get to stretch.

　　That may be adding danger to discomfort, studies have found. The discomfort part you already know about. The danger is that when your body is left in a cramped position for too long, blood clots(血塊) can form in your feet and legs. That’s dangerous, because a blood clot that (2)dislodges(移動，逐出) will travel in the blood stream. And that’s nothing to play around with. If it reaches your lungs, it could even kill you!

　　Now, of course not every hurting leg is indication of a blood clot. For the most part it’s just cramped(抽筋的) muscle. But research conducted at Tripler Army Medical Center in Honolulu showed that a surprising one out of four patients in a study group being treated for blood clots in the lower legs had been on airplanes within the past month. And a (3)whopping(巨大的) eighty-two percent still had symptoms(癥候，癥狀) two weeks after their flight!

　　The problem is that sitting for four hours or more reduces blood (4)circulation(循環) in the legs, especially if you are cramped up. So, to keep the old juices flowing, and to help lower the chance of blood clots forming during a long flight, get up and walk a little in the aisle(通道，走廊).
