     A mountain climbing fan died of altitude disease (高山病) on Tuesday on his return trip from the

Mount Qomolangma. Wu Wenhong, from east China's Jiangsu Province, died at around 4 a.m. at 8,750

meters of the world's tallest peak (山峰), said sources with the mountaineering association in southwest

China's Tibet Autonomous Region. Wu reached the peak of Qomolangma on Monday moming, but on

the retum trip the part-time climber was hit by bad altitude disease which put his life in serious danger.

The 8,300-meter camp sent a rescue (急救) team that had three professional (专业的) mountaineers for

help,  but Wu failed to become well after a night's rescue efforts. "It happened at a high altitude with quite

cold and hard path, so our rescue work was met with a lot of trouble.  We sent professional mountaineers with oxygen, tent and camp stove (炉) , but it all proved (证明) useless," said Nima Ciren, head of the

Tibet Mountaineering Team.

     A total of 24 Chinese part-time climbers were interested in climbing the Mt. Qomolangma this

season. The first team that has eight climbing fans,  reached the top on Sunday and came back safely.

The second team of 12 climbers got to the 8844.43-meter peak on Monday morning.  All the other

climbers returned safely.

根据短文内容判断正(A)误( B)。
