What caused their sickness？The sick rescuers had altitude sickness（高原反應(yīng)）．
The higher a place is above sea level，the less oxygen there is in the air．This causes problems for people who live in lower place．These bodies aren't used to working on so little oxygen．
All kinds of people can get altitude sickness．But some people get altitude sickness easier than others．Most people can go up 2，483 meters without getting altitude sickness．
How to deal with altitude sickness？Some of the first signs of altitude sickness are headache，weakness，trouble sleeping and stomachache．Some people may have trouble breathing．

Answer 1

分析 本文是一篇人物故事類短文，主要介紹了玉樹發(fā)生地震的時候，很多參加救援的人員覺得頭暈，呼吸困難，睡不著覺，原來他們患了高原反應(yīng)，最后不得不離開了玉樹．高原反應(yīng)怎么發(fā)生的呢？由于在海拔高度地方，氧氣含量比較少．在海拔比較低的地方的人受不了在氧氣稀薄的狀況下工作，很多人都會患高原反應(yīng)，有的人會更容易患高原反應(yīng)，高原反應(yīng)的表現(xiàn)主要有頭痛，虛弱，睡不著，肚子疼，得了高原反應(yīng)之后要盡快到一個比較低的地方，不是很嚴(yán)重的話，你可以待在那里，讓你的身體適應(yīng)一下，但是不能鍛煉．

解答 56．C．細節(jié)理解題．根據(jù)"Some rescuers were seriously ill．At least 200 sick rescuers had to leave Yushu．"可知一些救援者離開玉樹的原因是由于患了嚴(yán)重的疾病，不得不離開玉樹，故選C．

57．D．細節(jié)理解題．根據(jù)"The higher a place is above sea level，the less oxygen there is in the air．"可知由于海拔高的地方，氧氣含量少，導(dǎo)致的高原反應(yīng)，故選D．

58．B．細節(jié)理解題．根據(jù)"Some of the first signs of altitude sickness are headache，weakness，trouble sleeping and stomachache．"高原反應(yīng)的表現(xiàn)主要有頭痛，虛弱，睡不著，肚子疼，可知除了感冒之外，其他幾項都是高原反應(yīng)的表現(xiàn)，故選B．

59．D．細節(jié)理解題．根據(jù)"The best treatment for altitude sickness is to go down to a lower place right away．If it isn't serious，you can stay there and let your body adjust（適應(yīng)）．But you should not exercise at all．"可知得了高原反應(yīng)之后要盡快到一個比較低的地方，不是很嚴(yán)重的話，你可以待在那里，讓你的身體適應(yīng)一下，但是不能鍛煉，所以跑步是不正確的，故選D．

60．C．主旨大意題．本文主要敘述了參加玉樹地震救援的人員有些患了高原反應(yīng)，不得不離開玉樹，然后分析了高原反應(yīng)的原因，癥狀，以及應(yīng)對措施．根據(jù)"The sick rescuers had altitude sickness"可知本文主要介紹了高原反應(yīng)的有關(guān)內(nèi)容，故選C．

點評 首先仔細閱讀短文，掌握大意，然后結(jié)合具體的題目再讀短文，從中找出相關(guān)信息，就可以確定正確答案．
