      China will remember the great moment. At 9: 00 a.m. on October 15th, 2003, the country sent up its first

manned spacecraft, ShenzhouⅤ, into space at Jiuquan Satellite Launch Center in Gansu Province.

      Now China has become the third country in the world to send a person into orbit (运行轨道) after the

former Soviet Union (前苏联) and the United States. Yang Liwei, 38, is China's first spaceman.

      Yang sent a message back to the earth, "I'm feeling very good in space, and it looks wonderful here." Yang

then told his wife and son, "I have looked at our beautiful earth and recorded all that I have seen here."

      It was planned that ShenzhouⅤwould circle the earth 14 times in about 20 hours.

      What did the spaceship take with? Flags and seeds (种子): a national flag, a United Nations flag, the Olympic

flag and one kilogram of seeds for experiments.

      Yang, who comes from Liaoning Province, has been an air force pilot since 1987. He was chosen from 14

pilots after many difficult tests.
