In 1962, John Glenn, at the age of forty, took a history-making ride aboard Friendship 7 to become the first man to orbit (绕轨道运行) the earth and to walk in space. He did it for science and for his country. Then in 1999, at the age of seventy-seven, Glenn made history again to take the flight back into space.
   When asked for comments on his trip, Glenn said, "Old folks have ambitions (志向) and dreams, too, like everybody else and why don’t they work for them? Why don’t they go for it? Don’t sit on a couch (长沙发) someplace, that’s my attitude."
