33-year-old spacewoman Wang Yaping made history----she is China's first teacher in space.
Wang Yaping taught Chinese primary and middle school students on Earth physics problems in the zero-gravity environment(失重环境).
She prepared for the lecture for a long time. Wang. born in January 1980, is from east China's Shandong Province. She was a pilot in the People's Liberation Army Air Force (空军)with experience of 1,600 hours of flying.
The world's first teacher in space was Christa McAuliffe, a 37-year-old middle school teacher from the United States, but the Space Shuttle Challenger(挑战者号)disintegrated(崩裂) after 73 seconds into flight on Jan.28, 1986. McAuliffe and other six members were killed.
"Wang's lecture was a pleasant surprise,”said Zhang Xiaoguang, an astronaut(宇航员) in the three members of Shenzhou-10 spacecraft. “                  (她无论做什么从不放弃). Sometimes we'd like to give her a helping hand, but she just would not take the handin help," said Nie Haisheng.
Like many young Chinese people, Wang likes photography, music and basketball. She said," We are all students in facing the university（宇宙）.We are looking forward to joining our young friends to learn and explore the mystical(神秘的)and beautiful universe."
