We may be wishing some memories could last a lifetime, but a large quantity of physical and emotional factors can have negative impact on our ability to keep the information throughout our whole life. A new study which had been published in the journal Psychological Science found that people who feel enthusiastic and cheerful—what psychologists call “positive effect”—are less likely to experience memory decline as they get older. This result adds to a growing body of research on the role of positive effect on healthy aging.
A team of researchers analyzed data from about 991 middle aged and elderly U.S. adults who participated in a national study conducted in three periods: between 1995 and 1996, 2004 and 2006, and
The researchers examined the association between positive effect and memory decline, which accounts for age, gender, education, depression, and negative effect.
“Our findings have clearly showed that memory declined with people becoming older,” said Claudia Haase, an associate professor at Northwestern University and senior author on the paper. “However, individuals with higher levels of positive effect had a less steep memory decline over the course of almost a decade,” added Emily Hittner, a PhD graduate of Northwester University and the paper’s lead author. Areas of future research might address the pathways that could connect positive effect and memory, such as physical health or social relationships.

Educators across the US are calling for major changes to the admission process in higher education. The National Center for Educational Statistics reported that U.S. colleges and universities received more than 9 million applications between
But a new report says that the problem is not about the number of students that are being admitted, but rather how students are selected. The Harvard School of Graduate Education, along with 80 other schools and organizations, released the report in January 2016, called “Turing the Tide---Making Caring Common”. The report argues that the process schools use to choose students causes major problems.
David Hawkins, the Executive Director for Educational Policy, says that most colleges and universities require many things from students when they apply. Schools usually ask for an essay describing a student’s interests or why they want to study at that school. The schools also ask for letters from teachers or other responsible adults describing why a student is a good candidate. But, Hawkins says, the area that schools are most concerned with a student’s high school grades and standardized test results.
The report suggests that paying attention to academic success over other qualities works well for some students but hurts others. In addition, academic success is not the most important quality a student should have. More attention should be paid to showing whether or not a student wants to do good in the world. The report also suggests that schools should ask for evidence that students care about other people. Moving attention away from academic ability will make process less about competition, the report says. Students will feel less stress about meeting higher and higher expectation.
But the report does have its critics. Bob Schaeffer, Public Education Director, said that every few years, someone makes the same argument for change. He said that no real change has happened yet and that even many of the schools that agree with the report still make no changes. “Many of the institutions that have supported the findings in the report are the very institutions that have the most competitive admission processes in the country," Schaeffer said.

The poaching, or illegal killing, of rhinos(犀牛) in South Africa is growing worse each year. The government recently reported that a record number of rhinos were poached in
The World Wildlife Fund, or WWF, says about 20,000 rhinos live in South Africa. That is more than 80 percent of the rhinos in the world. Edna Molewa, South Africa’s environmental issues minister, says, “During
The animals are hunted for their horns(犀牛角). Many people in Asia believe the horn has curing power, which drives poachers, at all costs, mad for more horns. But there is no scientific evidence for this belief. The horn is made of keratin. That is the same thing as human hair, fingernails and toenails.
Ms. Mo1ewa said 386 suspected poachers were arrested last year, an increase from the year before. But rhino protection workers say poachers often go unpunished after arrest. South Africa’s legal system is ineffective. Ms. Molewa said more needs to be done and South Africa is taking strong measures to protect rhinos. The efforts include moving some of the animals to secret places in neighboring countries. “Now approximately 100 rhinos have been moved to neighboring states in the SADC region during
Jo Shaw, the rhino program manager at the WWF, said, “we’re talking about a loss of a hundred rhinos a month. Or more than three a day. We really need to see effective action not just at a national level but internationally.” She says officials should find the criminal groups responsible for the poaching and punish them. Government officials are to meet in Botswana in March at the Inter-governmental Conference on Illegal Wildlife Trade.

We're so attached to plastic, but we're careless consumers. Waste plastic is entering our ecosystems and food chains with untold consequences. Cleaning up our polluted world of plastic may seem a noble, but thankless task. However, some people are seeing economic opportunity in the mission.
Plastic Bank, a social enterprise from Canada, is monetizing plastic recycling while empowering those most affected by the waste. It works to prevent waste plastic from entering oceans by encouraging people in developing countries to collect plastic from their communities in exchange for cash, food, clean water or school tuition for their children. After collection, plastic is weighed, sorted, chipped, melted into balls and sold on as“raw material”to be made into everything from bottles for cleaning products to clothing.
“I saw in large quantities; I saw an opportunity,”CEO David Katz told the audience at the Sustainable Brands Oceans conference in Porto, Portugal on November 14.“We reveal the value in this material,”he added.
Plastic Bank was founded in
The company says i has over 2,000 collectors working in the country, with its full- time collectors on average 63% above the poverty line thanks to the income they make from the project. Through its app based payment system, many collectors now have bank accounts for the first time, and are able to ultimately escape ultra poverty.
“Nothing we're doing is against the laws of physics,”said Katz. “All the technology exists for us to solve and save the world. It's only creative thought.”

In America,the number of people killed in car crashes in 2016 was above 40,000 for the first time in a decade,data released on Wednesday shows.
“Americans believe there is nothing we can do to stop crashes from happening,but that isn't true.We are behind the rest of the developed world in addressing highway fatalities(死亡).We just haven't been willing to do what needs to be done,”said Deborah A.P.Hersman,president of the National Safety Council.
The National Safety Council data shows a 6 percent increase in deaths in 2018 when compared with 2015 and a 3 percent increase in the number of miles Americana drove in 2016.
“Motor vehicle fatality numbers have been ringing the alarm for two years,”Hersman said.“Unfortunately,we have been blind to the data and the killings on our roadways.If we fail to take action,the death tell will continue to rise.”
“The trend is clear:After years of progress,highway deaths are heading in the wrong direction,”said Jonathan Adkins,a state safety official.
The number of people killed reached a record low of 32,675 in
Safety advances including increased seat-belt use,air bags,anti-lock braking,stability controls and electronic warnings and cameras.
The bad economy and high gas prices also influenced the reduction in deaths.Now,with unemployment and gas prices both low,more people are driving for work and pleasure trips.
“It’s not just that Americans drive more miles when the economy improves ;it’s the kind of miles they drive,”said Adrian Lund,president of the Insurance Institute for Highway Safety.
1. What’s Hersman’s attitude towards the present situation?A.It has been getting better. | B.It can hardly be improved. |

While many countries love their tea, UK citizens are particularly proud of being “tea people”. The average UK citizen consumes nearly 2 kilograms of tea each year.
Tea only made its way to England in large quantities in the first years of the 17th century. Tea from China and a few other Asian countries was being sold more widely in England at that time. Then tea was getting more and more popular among different social classes.
There are many varieties of tea. Black tea mixtures are still the most common type drunk in the UK. Black tea is dark in colour, because the leaves have been allowed to oxidize (氧化) before drying. This is why we usually serve it with milk, although it is not uncommon to drink it black or with lemon. You may still find tea made with loose tea leaves, served up in a pot, and poured into the best china cups with saucers (茶托) for visitors.
Tea is still a large part of daily life in the UK today, but it seems to be on the decrease. The amount of tea sold in the UK fell by more than 10% in the five years leading up to 2002, and has been dropping ever since. Tea sales fell by 6% in
