单选题Over the past few years, a growing number of America's parentless children have found homes. In 2008 there were 463,000 children in foster care, a system where the government places orphans and children with parents who are abusive or unable to take care of them in the care of guardians. That is 11% down since 2002, and great news. But experts worry the trend might now go into reverse. Some welfare advocates fear that the bad economy may cause parents with frayed nerves to abuse and neglect their children, and even cause some to abandon them. Already, several hospitals across the country have reported an increase in the frequency and severity of injuries from child abuse. The most recent national data on child welfare available dates from September 2008, before the recession was in lull throttle; data from 2009 won't be reported until later this year. But there is some question about whether the data, when reported, will even be accurate. Many states and counties, in an attempt to cope with their fiscal straits, are considering cutting down on child-welfare services, such as benefits for foster parents and the number of social workers they employ. The average workload of caseworkers had already increased by 7% between 2006 and 2007, says Mary Hansen, of American University in Washington, DC. With more budget cuts, there will be fewer caseworkers to take notice of abuse and neglect, she says, and it will be more difficult to find someone to report problems to, potentially affecting the collection data. In the meantime, more parents are trying to keep their families intact. New York Foundling, an agency in New York, runs a crisis centre, where parents can leave their children tot up to three weeks. Requests for beds increased 20% in the last year. Safe Families, a non-profit outfit that places children in temporary homes with volunteer families until jobless parents can get back on their feet, saw the number of children it serviced triple in 2009, and it expects that number to double again in 2010. Most people are asking ['or help from Safe Families, says the organization's founder, David Anderson, because they don't want to risk losing custody, as they would if they put their kids into foster care. Thankfully, the recession has actually spurred more volunteers to come forward, says Mr. Anderson.

单选题Even at the Vatican. not all sacred beliefs are absolute: Thou shalt not kill, but war can be just. Now, behind the quiet walls, a clash is shaping up involving two poles of near certainty: the church's long-held ban on condoms and its advocacy of human life. The issue is AIDS. Church officials recently confirmed that Pope Benedict XVI had requested a report on whether it might be acceptable for Catholics to use condoms in one narrow circumstance: to protect life inside a marriage when one partner is infected with H.I.V. or is sick with AIDS. Whatever the pope decides, church officials and other experts broadly agree that it is remarkable that so delicate an issue is being taken up. But they also agree that such an inquiry is logical, and particularly significant from this pope, who was Pope John Paul II’s strict enforcer of church doctrine. "In some ways, maybe he has got the greatest capacity to do it because there is no doubt about his orthodoxy," said the. Rev. Jon Fuller, a Jesuit physician who runs an AIDS clinic at the Boston Medical Center. The issue has surfaced repeatedly as one of the most complicated and delicate facing the church. For years, some influential cardinals and theologians have argued for a change for couples affected by AIDS in the name of protecting life, while others have fiercely attacked the possibility as demoting the church's long advocacy of abstinence and marital fidelity to fight the disease. The news broke just after Benedict celebrated his first anniversary as pope, a relatively quiet papal year. But he devoted his first encyclical to love, specifically between a man and a woman in marriage. Indeed, with regard to condoms, the only change apparently being considered is in the specific case of married couples. But any change would be unpopular with conservative Catholics, some of whom have expressed disappointment that Benedict has displayed a softer face now as defender of the faith than he did when he was still Cardinal Joseph Ratzinger, the papal adviser. "It's just hard to imagine that any pope—and this pope—would change the teaching," said Austin Ruse, president of the Culture of Life Foundation, a Catholic-oriented advocacy group in Washington that opposes abortion and contraception. It is too soon to know where the pope is heading. Far less contentious issues can take years to inch through the Vatican's nexus of belief and bureaucracy, prayer and politics, and Cardinal Javier Lozano Barragan, the pope's top aide on health care issues, and other officials declined requests for interviews.

单选题Researchers have found that REM (rapid eye movement)sleep is important to human beings. This type of sleep generally occurs four or five times during one night of sleep lasting five minutes to forty minutes for each occurrence. The deeper a person's sleep becomes, the longer the periods of rapid eye movement. There are physical changes in the body to show that a person has changed from NREM (non-rapid eye movement)to REM sleep. Breathing becomes faster, the heart rate increases, and, as the name implies, the eyes begin to move quickly. Accompanying these physical changes in the body there is a very important characteristic of REM sleep. It is during REM sleep that a person dreams.

单选题In 1965, the United States made important changes in its immigration laws, allowing many more immigrants to come and entirely eliminating the older laws' bias (偏见, 偏向) in favor of white European immigrants. As a result, the United States is now confronted with a new challenge—taking in large numbers of new immigrants who are nonwhite and non-European. About 90 percent are from Asia, Latin America, and the Caribbean. In addition to the large numbers of legal immigrants, for the first time the United States has significant numbers of illegal immigrants. Many worry about what the impact will be on the American society. Can the American economy expand enough to offer these new immigrants the same opportunities that others have had? What will be the effect on the traditional value system that has defined the United States for over 200 years? Many Americans see wonderful benefits for their country. Ben Wattenberg, a respected expert on American culture, believes that the "new immigration" will be of great help to the nation. According to Wattenberg, something very important is happening to the United States: It is becoming the first universal nation in history. Wattenberg believes that the United States will be the first nation where large numbers of people from every region on earth live in freedom under one government. This diversity, he says, will give the nation great influence and appeal to the rest of the world during the 21st century. Perhaps the United States will be described not as a "melting pot" or a "salad bowl" but as a "mosaic"—a picture made up of many tiny pieces of different colors. If one looks closely at the nation, the individuals of different colors and ethnic groups are still distinct and recognizable, but together they create a picture that is uniquely American. "E Pluribus Unum" —the motto of the United States from its beginning—means one composed of many. "Out of many, one. /
