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."

American black bears appear in a variety of colors despite(尽管) their name. In the eastern part, most of these bears have shiny black fur, but in the west they grow brown, red, or even yellow coats. To the north, the black bear is actually gray or white in color. Even in the same litter(胎), both brown and black furred bears may be born.
Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is timid and rarely dangerous, but if attacked, most can climb trees or cover ground at great speed. When angry or frightened, they are formidable(可怕的) enemies.
Black bears feed on leaves, roots, fruit, insects, fish, and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike squirrels and many other woodland animals, bears do not actually sleep through the winter months. Although the bear does not eat during the winter months, sustaining(维持) itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute.
Most black bears live alone, except during the mating(交配) season. They prefer to live in caves. Baby black bears are born in January or February after a gestation(怀孕) period of six to nine months, and they stay with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild, and even longer in some nature reserves.
【小题1】American black bears may have ___________ colours according to the passage.

When women sit together to watch a movie on TV, at the same time they usually talk about a lot of subjects, including children, men, careers and what’s happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen---they can’t do both---and they don’t understand that women can. Besides(此外), women think that the point of all getting together is to have a good time and develop relationships--not just to sit there like couch potatoes staring (盯着) at the screen.
During the ad breaks, a man often asks a woman to explain the plot(the story that is told in a novel or play or movie etc.) and tell him where the relationship between the characters is going. He is unable, unlike women, to read the small body language signals that show how the characters are feeling emotionally(情绪上). Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully because they want to keep relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to connect to the facts.
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a way of keeping relationship. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.
There is no convincing(令人信服的)evidence that social conditioning, the fact that girls’ mothers talked them more, is the reason why girls talk more than boys. Psychiatrist Dr. Michael Lewis, author of Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at baby girls more often than baby boys. Scientific evidence shows parents reply to the brain differences of their children. Since a girl’s brain is better organized to send and receive speech, we talk to them more. As a result, mothers who try to talk to their sons are usually pointed to receive only short complaints in reply.
【小题1】While watching TV with others, women usually talk a lot because they ___________.
