It is difficult to imagine what life would be like without memory. The meanings of the thousands of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.
Memory can be defined as the capacity to keep information available for later use. It includes not only “remembering” things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed (发觉) something suspicious in the grain pile. Memory is also involved when a sixyearold child learns to swing a baseball bat.
Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for strong data for later use. It is interesting to compare the memory storage capacity of a computer with that of a human being. The instantaccess memory of a large computer may hold up to 100,000 “words” —ready for instant use. An average US teenager probably recognises the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognise on sight.
The use of words is the basis of the advanced problemsolving intelligence of human beings. A large part of a person’s memory is in terms of words and combinations of words.

First, Facebook allows you to find and rediscover friends and then reminds you of these connections, so that you are less likely to fall out of touch with the long-lost school friend, or the family member in a different country. 'Second, Facebook creates an environment that allows you to interact easily with others : you can share your photos,videos,links and thoughts with your friends, and respond to what they share in turn. Third, Facebook’s unique technical system helps you to discover your friends,most valuable stories. These technologies allow people to keep and enrich friendships that they might otherwise have been unable to keep.
The effect of this is very great. A recent study by Keith Hampton for the Pew Internet and American Life Project discovered that users of social networking websites have larger, more diverse social circles, online and offline. This outcome comes at no cost to one’s closest relationships, which are kept in person and over the phone. Instead, the hour that the average user spends each day socializing on Facebook comes at the expense of less social activities, such as the three or so hours a day the average person spends watching television.
Time may limit our ability to keep social ties, but our desire for social communication is limitless. Just as boats have allowed us to cross oceans and vehicles have allowed us to move mountains, Facebook is a tool that allows us to stay more deeply connected with a larger and more diverse set of friends.

【推荐2】Teenagers are supposed to be moody, right? One moment they are happy and laughing the next they are slamming their door to their room and crying into their pillow. You tell yourself, “Its just hormones,” and try to brush it off. Chances are you are right.

The Wealthy Society is a modern classic because it helped describe a new moment in the human condition. For most of history, “hunger, sickness, and cold” threatened nearly everyone, Galbraith wrote. “Poverty (贫穷) was found everywhere in that world. Obviously it is not of ours.” After World War II, the fear of another Great Depression gave way to an economic growth. In the 1930s unemployment had averaged 18.2 percent; in the 1950s it was 4.5 percent.
To Galbraith, materialism (物质主义) had gone mad and would cause discontent. Through advertising, companies conditioned consumers to buy things they didn’t really want or need. Because so much spending was artificial, it would be unsatisfying. Meanwhile, government spending that would make everyone better off was being cut down because people wrongly considered government only as “a necessary bad.”
It’s often said that only the rich are getting ahead; everyone else is standing still or falling behind. Well, there are many undeserving rich — overpaid chief managers, for instance. But over any meaningful period, most people’s incomes are increasing. From 1995 to 2004, people feel “squeezed” because their rising incomes often don’t satisfy their rising wants — for bigger homes, more health care, more education, and faster Internet connections.
The other great disappointment is that it has not got rid of insecurity. People regard job stability as part of their standard of living. As company unemployment increased, that part has gradually become weaker. More workers fear they’ve become “
Because so much previous suffering and social conflict resulted from poverty, the arrival of widespread wealth suggested utopian (乌托邦式的) possibilities. Up to a point, wealth succeeds. There is much less physical suffering than before. People are better off. Unfortunately, wealth also creates new complaints.
Advanced societies need economic growth to satisfy the multiplying wants of their citizens. But the search for growth cause new anxieties and economic conflicts that disturb the social order. Wealth sets free the individual, promising that everyone can choose a unique way to self-accomplishment. But the promise is so unreasonable that it leads to many disappointments and sometimes inspires choices that have anti-social consequences, including family breakdown. Figures indicate that happiness has not risen with incomes.
Should we be surprised? Not really. We’ve simply confirmed an old truth: the seeking of wealth does not always end with happiness.

【推荐1】Past studies have found that youngsters are less good at identifying road dangers than adults, but Anat Meir wanted to discover exactly which behaviors lead to accidents, with the goal of finding ways to correct them.
In 2013, Meir simulated 18 typical streets and used an eye-tracking device to study how 46 adults and children evaluated when it was safe to cross. Children aged seven to nine exhibited the least caution when crossing, typically deciding to step into the virtual road with little or no hesitation, even when their field of vision was restricted. The older children did not perform much better, though for different reasons. They often stayed on the curb for an excessive amount of time—an indication that they are less able to distinguish between safe and dangerous situations than adults—and in interviews did not express an understanding of how factors such as car speed and field of vision affect crossing safety.
Interventions do seem to improve crossing success. In Meir's most recent study, two dozen seven-to nine-year-olds receive 40 minutes of danger-detection training. Afterwards, Meir compared trainees' and control kids' performances in the virtual road-crossing task. The children who received safety instructions were significantly better at crossing than the control subjects-to the point that their crossing skills resembled those of adults.
Next, Meir and policy makers aim to figure out how to translate these findings into the real world. “These kind of results are important because you cannot build interventions without an understanding of the problem,” says Joseph Kearney, a professor of computer science. “Now it's up to people with their feet on the ground to determine how they can develop training programs for children and for parents about good road-crossing habits.”

【推荐2】As sea levels climb, even Washington, D. C. could see more frequent and widespread flooding at high tide.
Strong storms and high winds sometimes bring floods to coastal areas. But cities and towns along the US East Coast are flooding even in calm and sunny weather. Among them is Maryland’s capital Annapolis. Tourists there must sometimes walk through water flooding downtown streets surrounding the harbor. Sometimes water covers roads in Atlantic City, N. J. Even the yards and basements of coastal homes near New York City sometimes flood.
All are suffering from this trend—normal high tides surpass (超过) a rising sea level.
Sea levels have climbed, on average, about 20 centimeters (8 inches) over the past 135 years. And a sharp increase in tide flooding is one of the more visible impacts affecting many coastal areas, notes William Sweet, an oceanographer.
Sweet and his co-workers recently analyzed data from 45 tide gauges (计量表) along the US coasts. These tools record the changing heights of tides as they rise and fall. From these data, Sweet’s team calculated the number of : “troublesome floods” in various coastal cities. These floods, Sweet explains, typically occur when water level is about 30 centimeters (1foot) above the historic level of the highest tides. In June 2014, the team reported finding a growing rise in these flooding events.
In Charleston, S.C. from 1957 to 1963, the city experienced troublesome floods an average of 4. 6 days per year. Bur from 2007 to 2013, the occurring rate of troublesome floods jumped five times. Annapolis city was even more serious. From1957 to 1963,troublesome floods were roughly 3. 8 days per year. From 2007 to 2013, the average was 10 times higher- 39. 3days a year.
“Over the next few decades, climate change probably drives sea levels even higher,” Sweet says. “So today’s flooding problems promise to become only more widespread and frequent.”

【推荐3】“Our research has shown that the No. 1 reason people become fans is that it's your connection to your first community,” said Adam Earnhardt, chairman of the communications department at Youngstown State University and co-author of Sports Fans, Identity and Socialization: Exploring the Fandemonium. “I don't care if a Seattle fan moves to China, he or she carries with them their love for the sports teams,” he said. “
“It's phenomenal,” said Simons. “We have this ability to understand other people so remarkably that their victories literally become ours. Our testosterone literally responds to their victory.
Professor Robert Cialdini at Arizona State University came up with the term BIRG— Basking In Reflected Glory—to describe the intense pride fans feel when their teams succeed. It can be used as a verb, as in, "Seahawks' fans are currently BIRGing up a storm." The counterpoint, as coined by researchers C. R. Snyder, Mary Anne Lassergard and Carol E. Ford, is the concept of CORFing—Cutting Off Reflected Failure.
This leads into another concept, that of cognitive bias, also known as confirmation bias, which causes fans to help explain away defeats by blaming outside factors, such as referees. I'm sure it would also help explain why Seahawks fans rallied around Richard Sherman after his postgame interview, rationalizing behavior that was widely criticized by many fans with no vested interest. It could also explain the notion of "eustress", invented by endocrinologist Hans Selye to refer to a combination of euphoria(极度愉快的心情)and stress, such as that resulting from watching tense sporting events. Indeed, it's much of the appeal.

NHS Responders
After asking retired medical professionals to return to work, the government has also put out a call for 250,000 volunteers to support the NHS (National Health System). You can apply to be a community response volunteer, collecting and delivering supplies for those in isolation; a patient transport volunteer, helping patients who are dismissed from hospital get home and settled; and an NHS transport volunteer, to assist with delivery of medical supplies.
GAIL'S Bakery
As well as baking breads and pastries for the general public, GAJL's is supplying front-line NHS teams with fresh food, and they need more help to get it where it needs to be. If you want to lend a hand, drop them an email.
Re-engage
Re-engage is a voluntary group that helps reduce loneliness among old people and given that so many people are isolated because of the virus outbreak, they need more volunteers to become call companions. If you want to join them in the telephone befriending service, contact them at 18112256.

【推荐2】In Western countries people have been using the installment plan since the first half of the twentieth century.Today, a large number of families in Great Britain buy furniture, household goods and cars by installments In the U.S.A, the figure is much higher than in Great Britain, and people there spend over 10 percent of their income on the installment plan.
The price of an article bought on installments is always higher than the price that would be paid by cash.There is a charge for interest.The buyer pays one quarter or one third of the price as a down payment when the goods are delivered to him.He then makes regular payments, weekly or monthly,until the full price is paid up.The legal ownership of the goods remains with the seller until the final payment has been made.
Installment buying has advantages and disadvantages. It can help couples with small incomes to fumish their homes and star housekeeping, It increases the demand for goods, and in this way helps business and employment .There is ,however, the danger that when business is bad, installment buying may end suddenly, making business much worse.This may result in a great increase in unemployment.If the people on the installment plan lose their jobs, they will probably not be able to make their payments.If great numbers of people are not able to pay their installment debts, there is a possibility that businessmen cannot collect their debts and will therefore lose money.If businessmen lose money or fail to make a satisfactory profit, it becomes more likely to have a depression .This is why, in some countries,the government controls the installment plan by fixing the amount of the down payment and installments to discourage people from buying more than they can pay for on the installment plan.

【推荐3】Before your puppy can start offering its tricks for a specific reward, it needs to learn them! When training is started at seven to eight weeks of age, use methods that rely on encouragement and gentle teaching. Puppies have short attention spans (持续时间), so training sessions should be brief, but should occur daily.
Puppies can be taught to sit, lie down, and stand using a method called food-lure (食物引诱) training. Small pieces of food or a favored toy can be used to motivate your puppy to perform most tasks. Provided the reward is appealing enough, the puppy can be encouraged to give the desired response by showing the puppy the reward, moving the reward to get the desired response and then after some time, pairing a cue (a verbal command) with the behavior.
You should only ask your puppy to perform a behavior with a verbal cue once you are sure the puppy knows it well. If the puppy does not immediately give the behavior on the first encouragement, then you are likely proceeding a little too quickly. If you keep repeating the cue, the puppy will learn that several repetitions are acceptable before it needs to respond.
You do not necessarily need to train in a set session daily. Rather, integrate these tasks throughout the day. A goal to strive for is at least 15 minutes of training every day. These can be short five-minute sessions spread throughout the day. Try to have all family members ask your puppy to do these tasks. Remember to try and train in every room of your house. You want your puppy to sit, lie down and stay everywhere, not just in the training location.
