A long-term American study shows the importance of early education for poor children. The study is known as the Abecedarian Project. It involved more than one-hundred young children from poor families in North Carolina.

    Half of the children attended an all-day program at a high-quality child-care center. The center offered educational, health and social programs. Children took part in games and activities to increase their thinking and language skills and social and emotional development. The program also included health foods for the children.

    The children attended the program from when they were a few weeks old until the age of five years. The other group of children did not attend the child-care center. After the age of five, both groups attended public school.

    Researchers compared the two groups of children. When they were babies, both groups had similar results in tests for mental and physical skills. However, from the age of eighteen months, the children in the educational child-care program did much better in tests.

    The researchers tested the children again when they were twelve and fifteen years old. The tests found that the children who had been in the child-care center continued to have higher average test results. These children did much better on tests of reading and mathematics.

    A few years ago, organizers of the Abecedarian Project tested the students again. At the time, each student was twenty-one years old. They were tested for thinking and educational ability, employment, parenting and social skills. The researchers found that the young adults who had the early education still did better in reading and mathematics tests. They were more than two times as likely to be attending college or to have completed college. In addition, the children who received early education were older on average, when their first child was born.

    The study offers more evidence that learning during the first months and years of life is important for all later development.

    The researchers of the Abecedarian Project believe their study shows a need for lawmakers to spend money on public early education. They believe these kinds of programs could reduce the number of children who do not complete school and are unemployed.

    Beneath the water in the China's Qiandao Lake lies a hidden treasure. The ancient city of Shi Cheng (also known as Lion City), located in the province of Zhejiang, has been submerged underwater for 53 years. Shi Cheng was founded about 1,300 years ago in a valley surrounded by the Five Lion Mountains. When the Chinese government decided they needed a new hydroelectric power station (水力发电站)， a dam and man-made lake were constructed and the city was left at the bottom of this new body of water. Now, it sits at depths ranging from 85 feet to about 103 feet.

    Much like the Machu Picchu ruins in Peru, this underwater city remained forgotten until some renewed interests lead to its rediscovery. Qiu Feng, a local official in charge of tourism thought about utilizing Shi Cheng for entertainment on the lake and as a destination for diving clubs. On September 18, 2001, scuba divers made their first attempt underwater. "We were lucky. As soon as we dived into the lake, we found the outside wall of the town and even picked up a brick, "Qiu told Guangzhou Daily in an interview. More research was conducted, and it was discovered that the entire town was intact (1881), including wooden beams and stairs. After the initial findings, international archaeologists and a film crew then recorded the preservation of the lost ruins.

    Looking at surface of the lake, dotted with over 1,000 islands, you'd never know that an entire city was below.

    It's incredible to think that after all this time, the structure still remains intact and we could one day visit it. Until then, Shi Cheng will continue to remain inconspicuously submerged.

    I've been really lucky this year. Not only did I have the opportunity to live in France, but I was able to see some other countries with my girlfriend. Now she is studying in Essen, a large city in Western Germany. I recently went to stay with her—it was my first visit to Germany! Essen is a very large city. It has all the conveniences of any large city so I felt immediately at home. I loved the variety of shops, restaurants, shopping malls, cocktail bars, nightclubs, parks and even a lake. There is also a city­wide network of trams, which makes getting around a piece of cake!

    I found the people to be really friendly, and most Germans speak very good English which made life easy for me. I was surprised by the casual attitude to alcohol in Germany, where it seems normal for people to drink beer on the street, or on the tram. My girlfriend and I visited two famous local cities, Düsseldorf and Cologne, which are both on the Rhine River. Düsseldorf is an urban metropolis with a great variety of restaurants. We took a boat tour on the river and went up the Rhine Tower, a really tall building which offers great views across the city. Cologne, as you might know, is world-famous for its perfumes. The cathedral there is an unmissable landmark. We made the effort to climb to the top of one of the cathedral's towers. The spiral (螺旋的) stairs seemed endless, but it was worthwhile for the impressive sights from the top.

    We also went in a cable car over the river and tasted a German delicacy called "Spaghettieis" which is ice cream with strawberry sauce! I also got to try the famous German sausage. I must admit, I really enjoyed the food! The only disappointment was the grey and rainy weather, which proves that Britain does not have the worst weather in Europe!

    Millions of Americans are living in areas at high-risk of river flooding, many of whom are completely unaware of the danger.

    While the risk of coastal flooding from extreme storms and rising seas rightly attracts plenty of attention, Americans are being urged to look inland for a similar threat receiving far less recognition: river flooding. New research conducted by the University of Bristol has shown that as many as 41 million Americans are highly at risk from river floods – more than three times the number previously estimated – with real estate (住宅区) in areas such as Louisiana, Florida, Arizona and West Virginia found to be especially at threat.

    For the first time, it has been possible to produce super quality flood risk maps that cover the whole United States, while previous Federal Emergency Management Agency (FEMA) flood maps cover no more than 60 per cent of the country. The fine details provided by these new maps also makes it possible to predict the powerful effects of flooding on many smaller streams than before, thus raising concerns about the increasing number of people potentially threatened.

    "We were all surprised by how many Americans we find are exposed to flooding from rivers," says Oliver Wing, from the University of Bristol's School of Geographical Sciences. "It's particularly worrisome considering that most of these people aren't even aware of the risk they face."

    Additionally, there is the possibility that this lack of awareness means construction in high-risk river flooding areas will continue to rise, despite the threats. Estimates (估量) suggest that projected population growth, continued urbanization trends (城市化趋势), and the unpredictable threats caused by climate change will leave over 60 million Americans vulnerable (易受攻击的) to a 100-year flood by the middle of the century. 'All of this highlights the urgent need for large areas of floodplain and flood risk management planning,' adds Wing.

There's a useful concept from psychology that helps explain why good people do things that harm the environment: the false consensus effect. That's where we overvalue how acceptable and prevalent（普遍的） our own behavior is in society. Put simply, if you're doing something （even if you secretly know you probably shouldn't）, you're more likely to think plenty of other people do it too. What's more, you likely overestimate how much other people think that behavior is broadly OK.

This bias（偏见） allows people to justify socially unacceptable or illegal behaviors. Researchers have observed the false consensus effect in drug use and illegal hunting. More recently, conservationists are beginning to reveal how this effect contributes to environmental damage.

In Australia, people who admitted to poaching（偷猎） thought it was much more prevalent in society than it really was, and had higher estimates than fishers who obeyed the law. They also believed others viewed poaching as socially acceptable; however, in reality, more than 90% of fishers held the opposite view. The false consensus effect has also shown up in studies examining support for nuclear energy and offshore wind farms.

Just as concepts from psychology can help explain some forms of environmental damage, so too can they help address it. For example, research shows people are more likely to litter in areas where there's already a-lot of trash scattered around; so making sure the ground around a bin is not covered in rubbish may help.

Factual information on how other people think and behave can be very powerful. Energy companies have substantially reduced energy consumption simply by showing people how their electricity use compares to their neighbors. Encouragingly, stimulating people's natural desire for status has also been successful in getting people to "go green to be seen", or to publicly buy eco-friendly products.

As the research evidence shows, social norms can be a powerful force in encouraging and popularizing environmentally friendly behaviors. Perhaps you can do your bit by sharing this article!
