Often considered a "modem" celebration, Mother’s Day dates back more than 400 years and, today, it’s celebrated on (26) dates in different countries. So, if you’re from the UK or Ireland and feel as though Mother’s Day has come around again (27) quickly this year, it’s because you already celebrated it on March 30. There are two main dates (28) Mother’s Day: in Britain and Ireland it’s the fourth Sunday of March and for the US, Hong Kong, Australia and most of the world, it’s the second Sunday in May. The reason for the discrepancy is a somewhat (29) history. Many believe the holiday’s English (30) can be found in the 16th century where, on Laetare Sunday (fourth Sunday in Lent), Christians would-visit the main church in their region: the "mother church". This was also an era when children working as (31) would go home to visit family, and so the holiday known as "Mothering Sunday" (32) . The American (33) finds its roots twisted around the country’s bloody civil war and the story of Ann Marie Jarvis and her daughter Anna. Born in 1832 in the US, Ann Marie spent her life working to help the local community, (34) women and mothers. Among other things, she set up "Mother’s Day Work Clubs" to help women suffering from tuberculosis. Eight of her 12 children died through illness, four during the US civil war, but Ann Marie (35) her work. She died at age 73 on the second Sunday in May, 1905. Three years later, her daughter Anna organized the first official Mother’s Day celebration to honor her mother’s life.

Meat eaters in developed countries will have to eat a lot less meat, cutting consumption by 50%, to avoid the worst consequences of future climate change, new research warns. The fertilizers used in farming are responsible for a significant share of the warming that causes climate change. A study published in Environmental Research Letters warns that drastic changes in food production and at the dinner table are needed by 2050 in order to prevent disastrous global warming. It’s probably the most difficult challenge in dealing with climate change: how to reduce emissions from food production while still producing enough to feed a global population projected to reach 9 billion by the middle of this century. The findings, by Eric Davidson, director of the Woods Hole Research Centre in Massachusetts, say the developed world will have to cut fertilizer use by 50% and persuade consumers in the developed world to stop eating so much meat. Davidson concedes it’s a hard sell. "I think there are huge challenges in convincing people in the west to reduce portion sizes or the frequency of eating meat. That is part of our culture right now," he said. Researchers have been paying closer attention in the past few years to the impact of agriculture on climate change, and the parallel problem of growing enough food for an expanding population. Some scientists are at work growing artificial meat which would avoid the fertilizers and manure (粪肥) responsible for climate change. Nitrous oxide (一氧化二氮), released by fertilizers and animal manure, is the most potent of the greenhouse gases that cause climate change. The UN’s climate body has called for deep cuts to those emissions. Growing feed crops, for cattle and pigs, produces more of those emissions than food crops that go directly into the human food chain. Eating less meat would reduce demand for fertilizers as well as reduce the amount of manure produced. Davidson also suggests changes in current farming practice. For example, such as growing winter ground cover crops would help absorb nitrogen (氮) and prevent its release into the atmosphere. In reaching his conclusion, Davidson draws on figures from the Food and Agricultural Organization suggesting the world population will reach 8.9 billion by 2050. Meat consumption is also projected to increase sharply to 89kg per person a year in rich countries. Such a trajectory (发展轨迹) would put the world on course to more severe consequences of climate change. Davidson is not suggesting people give up meat entirely. "The solution isn’t that everyone needs to become a vegetarian. Simply reducing portion sizes and frequency would go a long way," he said. So would switching from beef and pork, which have a high carbon footprint (碳排放量), to chicken or fish. Which of the following can be the best title of the passage
Protecting Student Privacy in the Data Age A. In Kentucky, parents, educators and policy makers can track how many students from a high school go to college, and once they are there, how many require remedial classes (补习班). Massachusetts is one of several states with an early warning indicator system, which notifies school officials when students appear to be at risk for dropping out of high school. And in Georgia, teachers can easily access years of test scores, class, grades and attendance rates for any student. B. Student data advocates argue that used correctly data, including student attendance, test scores and demographics (人口统计), can enrich education. Teachers can better personalize instruction for students, principals can view the academic records of students who move across school districts and parents can determine whether a child is on track for college, to name just a few examples. C. But that promise comes with threats to students’ privacy. Parents have expressed concerns that if teachers have easy access to students’ entire academic histories, they might write off those with poor records, or that student information might fall into the hands of sexual predators (侵害者). Those concerns have led to heated debates about how much data schools should be collecting, how it should be stored and who should have access to it. D. Over the past year, the Common Core State Standards have also triggered discussions about student data, although the standards do not call for the federal government to collect data. "There’s no denying that education technology has the potential to transform learning if it’s used wisely," said Joni Lupovitz, vice president of policy at Common Sense Media, which this fall launched a campaign to raise awareness about student privacy issues. "What we’re working to ensure is that as educators, parents and student embrace more and more education technology, (and) balance the equation by focusing on student privacy to help ensure that we’re creating an atmosphere where kids can learn and be engaged and thrive without putting their personal information at risk." Relying on a 1970s Law E. Until recently, most states weighing privacy questions relied on the federal Family Educational Rights and Privacy Act (FERPA), a 1974 law intended to protect student education records. But in recent years, the U.S. Department of Education has made regulatory changes to the law, creating many exceptions. For example, education records now may be shared with outside contractors, such as private companies that track grades or attendance on behalf of school systems. The changes have prompted some states to examine whether they should play a stronger role in protecting student data. F. Paige Kowalski, director of state policy and advocacy for the Data Quality Campaign, a nonprofit that advocates for the effective use of data to improve student achievement, said states are starting to realize they need more sophisticated and comprehensive policies, regulations and practices around student privacy, and that they can’t just rely on FERPA. G. "All states have privacy laws on the books, but a lot of them are old," Kowalski said. "A lot of them just don’t have modem policies that were written acknowledging that data is even at the state level, let alone stored electronically and because of technology is able to move." Kowalski added that states’ privacy policies might refer to outdated information practices, such as checking out paper documents, while failing to discuss modem needs like encryption (加密). H. Most school districts rely on cloud computing—meaning data are stored on servers that can be accessed through the Internet—for everything from cafeteria payments to attendance records. But a recent study by the Center on Law and Information Policy at Fordham Law School concluded that most cloud-based services are "poorly understood, nontransparent and weakly governed" by schools. Most school districts fail to inform parents that they are using cloud-based services, and many contracts with web-based vendors (供应商) fail to address privacy issues, the study found. Keeping Parents in the Dark I. The Electronic Privacy Information Center, a nonprofit research group in Washington, D.C., filed a lawsuit in February 2012 against the U.S. Department of Education challenging its FERPA changes, but a federal court dismissed the lawsuit for lack of standing. J. Khaliah Barnes, the center’s administrative law counsel, said many schools and states are doing a poor job of informing parents of the issues that can arise with technology. She said school districts should tell parents about the kinds of information they collect, to whom that information is disclosed and for what purposes. Parents should also have the right to opt out of disclosing certain types of information, she said, and should be informed how to access and change incorrect information. K. Barnes said schools are using new technology to collect information that goes far beyond attendance records and test scores. Schools have used palm scanners to help students speed through cafeteria lines, and GPS or microchip (微芯片) technology to tell schools when students get on the right school buses or arrive at school, for example. L. One state leading the conversation on student data privacy is Oklahoma, which in June adopted the Student Data Accessibility, Transparency and Accountability Act establishing roles for the collection and transfer of student data by the state. "It was designed as a system of safeguards to protect student privacy," said state representative David Brumbaugh, a Republican, who sponsored the legislation. "It stops the release of confidential (机密的) data to organizations outside of Oklahoma without written consent of parents or guardians." M. The law prohibits the state from releasing any student-level data without state approval, which means the education department can release only data that is aggregated and cannot be tied to any individual student. "To my knowledge, we’re the only state that doesn’t release student-level data," said Kim Richey, general counsel for the Oklahoma Department of Education. N. Brumbaugh said he’s heard from lawmakers around the country interested in proposing similar legislation for their states. The conservative American Legislative Exchange Council has also proposed model legislation similar to the Oklahoma bill. O. Other states also have taken action on student data privacy this year: In New York, where a handful of bills related to student data privacy have been introduced in the legislature, the Senate Education Committee held a series of public hearings (听证会) on topics including student privacy around a planned data collection system. Last week, state senator John Flanagan called for a one-year delay in the launch of the data collection system. The Long Island Republican urged lawmakers to strengthen protections for data on the statewide data portal (门户网站) and set civil and criminal penalties for violations. Georgia Governor Nathan Deal, a Republican, signed an executive order in May prohibiting the state from collecting or sharing personally identifiable data on students and prohibiting student data from being collected for the development of commercial products or services. In October, the Alabama State Board of Education adopted a new policy on student data that allows the state to share student data with the federal government only in aggregate. The policy also calls on school districts to adopt their own policies on the collection and sharing of student data. Republican Gov. Terry Branstad of Iowa signed an executive order in October reaffirming that student data should be collected in accordance with state and federal privacy laws and that only aggregate student data would be provided to the federal government. Some states follow Oklahoma and have taken some measures to deal with student data privacy.
