But after three months' professional（专业的）training, she changed her mind. She went to Stanford University and started to study science. She studied stars and planets. She did researches at the university and got her PhD in astrophysics（天体物理学博士学位）after several years' hard work.

    In 1977, she took a test to become an astronaut. And then she was picked up from over 8, 000 people. In order to realize her dream of going into space, she had to get different kinds of special and difficult training.
