    Chinese astronaut Yang Liwei said that he had heard a mysterious knock
during his flight in space, China Central Television reported.
    中央电视台最近报道，中国宇航员杨利伟称在太空飞行期间，他听到了一种神秘的敲击声。
    Yang, born in June 1965 in northeastern Liaoning Province, is China’s first
astronaut and now a major general. On Oct. 16, 2003, he stepped out of his
re-entry module after a 21-hour flying in space, making him the 241st human
being worldwide to visit outer space.
    杨利伟于1965年6月出生在辽宁省，是中国第一位宇航员，目前是一名少将。2003年10月16日，经过21小时的太空飞行后杨利伟走出了太空舱，成为了世界上第241个造访太空的人类。
    When he recalled his experience in space during a recent interview, he
said, "A non-causal situation I have met in space is a knock that appeared from
time to time."
    在最近一次采访中，杨利伟回忆起了他在太空中的经历，说道：“我在太空中遇到的一种非因果常识情况就是时不时会出现一种敲击声。”
    He explained that the sound suddenly appeared without any rhyme or reason.
"It neither came from outside nor inside the spaceship, but sounded like someone
is knocking the body of the spaceship just as knocking an iron bucket with a
wooden hammer," Yang said.
    他解释说这种声音是突然出现的，没有任何韵律、也没有任何原因。杨利伟说道：“那个声音既不是来自飞船外也不是来自飞船内，但是听起来好像是某人在敲击飞船船体，就好像用木锤子敲铁桶一样。”
    Yang said he was very nervous when he heard the sound, and moved close to
the porthole to try to find out the cause. However, nothing out of the ordinary
appeared both inside and outside.
    杨利伟说当他听到这种声音时他非常紧张，靠近舷窗试图找出原因。但是，舱内舱外都没有什么异常情况出现。
    After returning to earth, he told technicians about the mysterious sound,
and tried to imitate it with some instruments, so as to solve the mystery. But
Yang said he had never heard the exact sound again.
    在返回地球之后，为了解决这个谜团，他把有关这种神秘声音的事情告诉了技术人员，并且试图用一些乐器来模仿这种声音。但是杨利伟表示说他再也没有听到过一模一样的声音。
    The sound has also been heard by Shenzhou 6 and Shenzhou 7 astronauts. Yang
said, "Before entering space, I have told them that the sound is a normal
phenomenon, so there is no need to worry."
    神舟六号和神舟七号的宇航员们也听到过这种声音。杨利伟说道：“在进入太空之前，我告诉他们这种声音是自然现象，所以没必要担心。”
