     Sarah left school at eighteen, went to collage and then worked at a computer company. Four years later,

she got a new job as a manager in British Airways (英国航空公司). This is what she told us about her job:

     "My office is at Heathrow Airport, but I spend 60% of my time in the air. I teach air-hostesses (空姐) and

help them with any problems I also go to lots of meetings.

     My hours are usually form 8 a.m. to 4 p.m. but sometimes I work from 1 p.m. to 9 p.m. At work, the first

thing I do is check plane times on my computer and then I speak with some of the air-hostesses.

     Sometimes I go on long flights (飞行) to check how the air-hostesses are doing. That's my favourite part

of the job, but I like office work, too. Travelling can be hard work. When I get back from a long trip, all I can

do is eat something and then go to bed! I don't make much money, but I'm happy with British Airways and

want to stay there and continue to travel."
