Get a reward for every bug you bring to live in new science museum exhibit.

In a city with trillions of American cockroaches(蟑螂), the Houston Museum of Natural Science has agreed to pay a quarter per bug－up to 1,000－as it seeks to populate a new insect exhibit alongside its Cockrell Butterfly Center.

Nancy Greig, the museum’s director insists the public payday for roaches isn’t just a marketing ploy(炒作).

“Absolutely, this wasn’t devised as a joke,” Greig said. “We needed more roaches for the exhibit, so I sent this message out to everyone in the museum asking people to bring them in. Well, someone decided to tell the press, and all hell has broken loose.”

“But we really do need cockroaches.”

“One might be forgiven for never considering how to catch a live cockroach. But it’s simple enough to fool them,” Greig said, “and even easier to catch them.” American cockroaches are the most common kind in Texas, measuring up to 2 inches long and invading homes.

Despite their less-than-attractive reputation, cockroaches actually aren’t that dirty. Greig even went so far as to call them “fastidious” saying they don’t enjoy rooting(用嘴拱食) in waste. They’re only dirty if, say, they used a sewer(下水道)line to gain access into a home.

The roaches collected by the museum will become part of a display in a new exhibit that showcases insects such as cockroaches, dung beetles and termites.

There’s more to like about roaches, too. They don’t bite, and they don’t carry diseases like a mosquito, so they’re generally safe to handle.

56．For what does the museum pay for cockroaches?

       A．For a marketing ploy.              B． It’s devised to make fun.

57．The underlined word “fastidious” probably means extremely ________.

       A．clean           B．dirty            C．unpleasant           D．fast  

58．What do we know about American roaches?

       A．It’s not easy for people in Houston to collect roaches.

       B．They all measure 2 inches and are often found in homes

       C．They don’t bite and they are free of disease.

       D．We have reasons to like them.

59．Which of the following can serve as the best title for the passage?

       A．The Houston Museum of Natural Science

       B．A new exhibit

       C．Quarters for cockroaches

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 a.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.”
