     Want to be an astronaut? Then "study hard, stay healthy and have perseverance (毅力)

      This is what Chinese astronauts Fei Junlong and Nie Haisheng said in a talk with some students.

      Students were interested in the astronauts' space lives. They asked questions like"Did you see the Great

Wall from space?" Fei and Nie said they didn't see the Great Wall. But they felt excited when they passed

over China, including Taiwan. The island "looked very beautiful, like a jade (翡翠)".

     Speaking of their lives beyond (在……之外) the earth, the two astronauts said cooperation (合作) with

each other was most important."We are like the left and right hands," they said.

      Young people wanted to know how the astronauts developed their careers (事业).
