    A 13yearold American boy on Saturday became the youngest climber to conquer Mount Everest,

the world's highest mountain.

     Jordan Romero from Big  Bear, California, climbed up the 8,850 meter summit (峰顶) from the

Tibetan side.On the same day, a Nepali (尼泊尔的)  man, Apa Sherpa, broke his own world record

of climbing Everest when he reached the summit for the  twentieth time.Apa Sherpa's team set off from

Nepal's  capital, Kathmandu, last month, heading for the base camp  (大本营) on the Chinese side of

the mountain.

     "The team has just called in and believe that they are standing on top of Mt.Everest, " Romero's blog

and needs to climb only Vinson Massif, the highest peak in Antarctica, to hit his goal.

    While Nepal insists that anyone planning to climb Mount Everest must be 16, China does not have any

age restrictions  (限制). Some mountain climbers haven't agreed with the Romero family for letting him try

it but his father said the climbing from the Chinese side is less dangerous.
