He is an a_________ member of this club and takes part in every performance organized by the club.

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 mean 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.”
