阅读理解。

     Margaret, married with two small children, has been working for the last seven years as a night

cleaner, cleaning offices in a big building.

     She trained as a nurse, but had to give it up when her elder child became seriously ill. "I would have

liked to go back to it, but the shifts (工作班次) are all wrong for me, as I have to be home to get the

children up and off to school."

     So she works as a cleaner instead, from 9 p.m. till 6 a.m. five nights a week for just ￡90, before tax

and insurance. "It's better than it was last year, but I still think that people who work 'unsocial hours'

should get a bit extra."

     The hours she' s chosen to work meant that she sees plenty of the children, but very little of her

husband. However, she doesn't think that puts any pressure on their relationship.

     Her work isn't physically very hard, but it's not exactly pleasant, either. "I do get angry with people

who leave their offices like a place for raising pigs. If they realized people like me have to do it, perhaps

they'd be a bit more careful."

     The fact that she's working all night doesn't worry Margaret at all. Unlike some dark buildings at night

, the building where she works is fully lit, and the women work in groups of three. "Since I've got to be

here, I try to enjoy myself-and I usually do, because of the other girls. We all have a good laugh, so the

time never drags."

     Another challenge Margaret has to face is the reaction of other people when she tells them what she

does for a living. "They think you're a cleaner because you don't know how to read and write," said

Margaret. "I used to think what my parents would say if they knew what I'd been doing, but I don't think

that way any more. I don't dislike the work though I can't say I'm mad about it."
