                           ★★★☆☆

    When I was a child,space was all I dreamt and talked about. My parents thought it was just a phase(階段) ，but as I grew up I became greatfy interested in science. I never doubted that one day I'd be an astronaut(宇航員) .” As an adult,Anousheh Ansari left her home country Iran,settled in the USA and started a company. The company was so successful that she was finally able to sell it for $750 million. uThe first thing that crossed my mind was that my life's goal might now be within reach and I signed up to become the first female(女性的) private space explorer at a cost of around $20 million."

    Anousheh set on on September 18th along with two astronauts. On the space station,each member of a space crew  crew(全體機(jī)組人員) ，tourist or not,is expected to carry out important siuuymg uiiy me luims umi uaii uaiiy uibcascs uu

board the station. Many people might have considered this “working holiday” bad、but Anousheh loved it.

that in the end it was hard to go back to normWify."
