Marjorie Baer used to joke about her retirement plans.She wasn't married and had no kids, but she didn't intend to be alone--she and all her single friends would move into a fictional home she called Casa de Biddies.Instead, Baer developed terminal brain cancer when she was 52.But just as she'd hoped, her friends and family provided her with love and care to the end. Ballance was only the first of Baer's friends who became her unofficial caregivers.With her brother Phil Baer from Los Angeles, they worked out a system to watch over their friend and allow her to keep some of the privacy and independence she cherished. Baer's good friend Ruth Henrich took Baer to doctors' appointments and helped her deal with all the aspects of life --answering machines, TV controls, and even phone numbers.After Henrich sent out an e-mail request, a group of volunteers signed up to ferry Baer back and forth to radiation therapy .Others in Baer's circle offered up particular talents: A nurse friend helped Baer figure out how to get what she was due from Social Security and her disability insurance; a lawyer pal helped Baer with her will; a partner who was an accountant took over her bills when she could no longer manage them."There was this odd sense that the right person always showed up," says Ballance.Their arrangement worked remarkably well. Unmarried women are one of the fastest-growing groups in America; experts are concerned about how care-giving will be managed for them as they age.If the experience of Baer's friends is a guide, _ .It's already making it possible to create communities of caregivers who may have only one thing in common: the person who needs their help.On personal "care pages" set up through services such as Lotsa Helping Hands, friends and family members can post a list of tasks that need to be done, volunteer to do them, and keep updated on the person's condition.As Baer's cancer progressed, for example, her friends set up a page on Yahoo! where people could sign up to deliver meals or do errands... The writer tells us the story of Marjorie Baer for the purpose of   _  . A) reminding us to be kind and make as many friends as we can B) informing that there will be a new trend of care-giving for the single elderly C) persuading us that we can enjoy our retirement even if we don't have a child D) introducing the convenience that will be brought by the Internet after we retire

Why do our eyes open wide when we feel fear? And why do our eyes become narrow when we express disgust  ? According to a new research, it has something to do with survival. In a recently published paper, researchers concluded that expressions of fear and disgust changed the way human eyes gather and focus light. They argued that these changes were the result of evolutionary development and were intended to help humans survive, or at least discover, very different dangers. In order to test their hypothesis  ,researchers examined two dozen volunteer college students with standard eye-exam equipment, and asked them to show expressions of fear and dislike. It was found that when the students widened their eyes, more light was admitted and their field of vision was expanded. When they wrinkled their noses in disgust, their eyes narrowed. This had the effect of blocking out more light but focusing on a specific point. Although some scientists have admitted that emotional expressions are intended primarily to communicate information, expressions of fear and disgust seem to perform different visual functions. "Eye widening may help to find a potential danger that requires much attention. And this would agree with the hypothesized function of fear," said researchers. "On the other hand, eye narrowing may help to distinguish and avoid different kinds of dangers, such as disease carriers and dirty foods. And this would agree with the hypothesized function of disgust." These findings supported naturalist Charles Darwin's view that expressions are not necessarily for communication and are not arbitrary  ."If our expressions were arbitrary, they would show little cross-cultural relationship." researchers said. "But actually, our expressions probably have some universal   functional principles." The main idea of the text is that   _  . A) emotional expressions change with cultures B) expressions of fear and disgust aid human survival C) evolutionary development causes changes of human eyes D) evolutionary development results in emotional expressions

Ques:The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on well with their parents, which is the opposite of the popularly-held image of unhappy teenagers locked in their room after endless family quarrels. An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past. "We were surprised by just how positive today's young people seem to be about their families," said one number of the research team. "They're expected to be rebellious and selfish but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat." So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. "My parents are happy to discuss things with me and willing to listen to me," says 17-year-old Daniel Lazall. "I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with me." Susan Crome, who is now 21, agrees. "Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that." Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, "Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really happened during that one time in the 1960s when everyone rebelled. The normal... Compared with parents of 30 years ago, today's parents   _  . A) go to clubs more often with their children B) are much stricter with their children C) give their children more freedom D) care less about their children's life
