填空题Do In-Class Exams Make Students Study Harder? Research suggests they may study more broadly for the unexpected rather than search for answers. A. I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question. B. Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly. C. As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. "That way they socialize over history outside the class, which wouldn"t happen without the pressure of an in-class exam," he explained. "Furthermore, in-class exams force students to learn how to perform under pressure, an essential work skill." D. He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled "Introduction To Congress." Some colleges have what they call an "honor code," though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn"t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going. E. Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school"s professors to refrain from take-home exams. "Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries," she told me. "Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention." F. Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches "History of Broadcast Journalism" at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. "In my field, it"s not what you know—it"s what you know how to find out," says Koch. "There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them." G. Students" test-form preferences vary, too, often depending on the subject and course difficulty. "I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research," says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, "I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up." Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. "If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze." H. How students ultimately handle tests may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there are those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions. I. Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, "We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school." J. If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, "I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test." It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class with the ticking clock overhead. K. Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, "It is going to be a piece of cake." When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.

填空题Caring for Elderly Parents Catches Many Unprepared A．Last July, Julie Baldocchi's mother had a massive stroke and was paralyzed. Baldocchi suddenly had to become a family caregiver, something that she wasn't prepared for. "I was flying by the seat of my pants," says Baldocchi, an employment specialist in San Francisco. Both of her parents are 83, and she knew her father couldn't handle her mother's care. The hospital recommended putting her mother in a nursing home. Baldocchi wasn't willing to do that. But moving her back into her parents' home created other problems. Baldocchi, 48, is married and lives about a mile away from her parents. She has a full-time job and has back problems that make it difficult for her to lift her mother. "I couldn't do it all," she says. "But I didn't even know how to find help." B．With help from the Family Caregiver Alliance, she eventually hired a live-in caregiver. "But even if you plan intellectually and legally, you're never ready for the emotional impact," Baldocchi says. In the first two months after her mother's stroke, she lost about 30 pounds as stress mounted. More than 42 million Americans provide family caregiving for an adult who needs help with daily activities, according to a 2009 survey by the AARP. An additional 61.6 million provided at least some care during the year. And many are unprepared. C．While many parents lack an advance care directive, it's the most basic and important step they can take. The directive includes several parts, including: a durable power of attorney, which gives someone legal authority to make financial decisions on another's behalf; a health care proxy, which is similar to the power of attorney, except it allows someone to make decisions regarding medical treatment; and a living will that outlines instructions for end-of-life care. (For example, parents can say if they want to be kept alive by artificial measures.) "It's invaluable for the kids, because it's hard to make those decisions for a parent," says Jennifer Cona, an elder-law attorney at Genser Dubow Genser & Cona in Melville, N.Y. An advance care directive is the first line of defense if a situation arises, says Kathleen Kelly, executive director of the Family Caregiver Alliance, which supports and educates caregivers. Without an advance directive, the family will have to petition the court to be appointed the parent's legal guardian, says AgingCare.com. D．It's important for families to talk about long-term care so the adult children know their parents' preferences, wishes and goals, says Lynn Feinberg, a caregiving expert at AARP. But it's not an easy conversation. Elderly parents are sometimes suspicious of their children's financial motives, says Susan John, a financial planner at Financial Focus in Wolfeboro, N.H. One client asked John to hold a family meeting because they needed an intermediary to talk about financial issues, she says. And when there are many siblings, the family decisions can become a three-ring circus with much acrimony, says Ann-Margaret Carrozza, an elder-law attorney in Glen Cove, N.Y. Families who need information and help sorting out disagreements can call on elder-law attorneys, financial planners, geriatric care managers and caregiver support groups. In February, AARP said it will offer its members a new caregiving support service through financial services firm Genworth. E．Many families are unprepared for quick decisions, especially when they find out that Medicare doesn't pay for long-term care, Feinberg says. The median cost of a year in a private room at a nursing home in 2011 was ＄77,745, according to Genworth. And only those who have spent most of their assets can qualify for Medicaid to pay for the nursing home. F．Assisted living is another option. Residents can have their own apartment to maintain some independence. But the facilities generally provide personal care services, such as meals, housekeeping and assistance with activities. Still, it's not cheap: The national median cost in 2011 was $39,135, according to Genworth. Assisted living isn't covered by Medicaid. G．If they have a choice, at least 90% of elderly parents prefer to stay at home as long as they can, according to AARP research. But if the parents can no longer safely live at home, it can be hard for children to move them into an adult care facility. There may be another option. Sometimes the home can be modified so a parent can stay there. For example, Baldocchi put in a chair lift for her mother. She also arranged for a home caregiver. H．Family caregivers take over many responsibilities. One might manage a parent's finances, while another sibling will take the parent to doctors' appointments and shopping. Those who move in with a parent take on a significant and sustained burden of care. Jan Walker moved into her mother's home in Leesburg, Fla. After her mother, who is 83, had fallen, she wasn't able to get around as well. Walker, 55, has three brothers. But she is the only daughter, is divorced and has no children. "I always knew that this was the role that I would have, and I guess my mind was prepared for it," says Walker, who now is a full-time caregiver and works from home as a tutorial instructor for a digital scrapbooking website. "When you get into the trenches, it's literally baptism by fire," she says. "New things come up. It's not just about advance planning for finances or medical care. It's everything," she says. I．Caregivers need to also watch their own health. "There is such a thing as caregiver burnout," Cona says. Among female caregivers 50 and older, 20% reported symptoms of depression, according to a 2010 study on working caregivers by MetLife. "It's a hard job," Walker says. "But most worthwhile things are hard. She was always there for me when I needed a helping hand. It's only natural that I be here for her now./

填空题School Lunch A. Ryan moved silently through the lunch line. The cook put a cheeseburger (奶酪汉堡) and an applesauce cup on his tray. He grabbed a bottle of milk from the cooler at the end of the line and found a seat in the cafeteria (食堂). Ryan saw that his friend Tyler had brought lunch from home. "What did you bring today, Tyler?" he asked. Tyler pulled his meal out of its brown paper sack. "I've got a ham sandwich, chips, two cupcakes, and a can of soda." Ryan's mouth started to water. "Uh, Tyler," he said. "If you don't want one of those cupcakes, I'll take it. They sure look good." Tyler handed Ryan his cupcake. "Sure," he said. "I won't eat all this." Lunch Requirements B. Is Ryan eating a healthy meal if he eats the school lunch? School lunch supporters say "Yes." Recent studies show that a government-approved school lunch has more variety and is more nutritious (有营养的) than most lunches brought from home. It's also lower in fat. C. The National School Lunch Act requires that school lunches go along with the Dietary Guidelines for Americans developed by the government. Meals must contain a variety of foods with plenty of grains and at least one fruit or vegetables each day. Foods must not contain too much sugar or salt. A hot lunch can contain up to 30% fat, but not more than 10% of its calories (卡路里) should come from saturated (饱和的) fat. In an average week, you should get one-third of the daily Recommended Dietary Allowances for protein, iron, calcium (钙), and vitamins A and C from your school lunch. Dare to Compare D. Let's compare Ryan's and Tyler's meals to see which is healthier. Ryan's hot lunch (without the cupcake from his friend) has 577 calories, 25 grams of total fat, and 12 grams of saturated fat. He had one serving of fruit, 26 grams of protein, and 483 milligrams of calcium. Ryan ate more total fat (39%) and saturated fat (19%) than the dietary guidelines recommend. However, schools can still meet the guidelines by having the numbers average out over a week of lunches. Tyler's lunch from home (this includes both cupcakes) had 1,014 calories, 45 grams (40%) of total fat, and 10 grams (9%) of saturated fat. He ate 21 grams of protein and 155 milligrams of calcium, but no fruits or vegetables. Tyler's meal met the saturated fat guidelines, but had too much total fat. Tyler ate more calories and total fat than Ryan did, Ryan ate more protein, calcium, and fruit than Tyler did. Which meal would you say is the healthier choice? à la Carte Options E. Federal standards and most school districts forbid selling food in the cafeteria that competes with the school lunch. Many programs do, however, offer à la carte choices for students who don't want the hot meal. Foods sold à la carte are separate from the main meal and are priced individually. These foods do not have to meet the same nutritional standards as the foods on the hot lunch menu. Neither do the foods sold at a snack-bar or those foods available elsewhere in the school. F. A study in one Texas school district compared the lunches of fourth graders who did not have food choices with those of fifth graders who could choose either a standard lunch or select from a snack-bar. The fourth graders ate 25% more fruits and vegetables than the fifth graders. G. Food sold as fund-raisers can also have an impact on school lunch. The money raised is important to provide needed funds for many after-class activities. But the meal's overall nutritional quality usually goes down. Many of these foods are high in fat, sugar, or both, and often come in extra large portions. Fund-raisers rarely sell fruits and vegetables. Choosing Wisely H. School food-service programs are trying to please students, and still offer quality, nutritious meals at low cost. That task isn't easy. One school district in New York decided to do something about it. A student advisory board kept the food-service director up-to-date on what the kids wanted. They also worked with school snack-bars to sell smaller servings of chips and candy. I. You can make healthy meal choices at school even when not-so-healthy choices are available. You can be sure to get a nutritious meal when you pick foods from the Food Guide Pyramid. For example, always drink milk or a calcium-rich juice for lunch. Even chocolate milk is more nutritious than soda or a sports drink. Stay away from snack foods offered à la carte. They may fill you up now, but the ones that contain a lot of fat and sugar will slow you down later. Always eat the fruits and vegetables offered at the meal. They help give you the energy and vitamins you need to get you through the rest of your school day. Some people like to make fun of school lunches, but good nutrition is no laughing matter. Your school's hot lunch is based on the Food Guide Pyramid, so it's full of nutrition. Give it a try. You might be pleasantly surprised. It's a Team Effort J. Team Nutrition is a program that gets schools excited about healthy eating. Schools across the nation pick a team leader who develops fun nutrition activities. The leader works with students, teachers, parents, food-service workers, and people from the community. Activities can range from running a school health fair to planting a garden. K. At the Jordan Community School in Chicago, Illinois, one group of fifth graders showed off their "pizza (披萨饼) garden" in a big, colorful poster showing vegetarian pizzas. The students and food-service staff planted and took care of the vegetables that they would later use as ingredients on their pizzas. The group started growing the plants in the school's cafeteria. Then they moved them outdoors to the students' demonstration garden. L. This is just one way to get everyone involved in making school lunch healthy and fun. Team up with your own group and see how creative you can get.
