    Money is the root of all evil (邪恶) and new study claims there may be some truth behind the saying. Scientists at the University of California Berkeley, US, announced on February 27 that rich people are more likely to do immoral things, such as lie or cheat, than poorer people. The scientists did a series of eight experiments. They published their findings online in the Proceedings of the National Academy of Sciences (PNA《美国国家科学院院刊》).

    They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut off other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive ears ignored a pedestrian compared with only 30 percent of people driving mow modest cars.

    In another experiment, a group of college students was asked if they would do immoral things in various everyday situations. Examples included taking printer paper from work and not telling a salesperson when he or she gave back more change. Students from higher — class families were more likely to act dishonestly.

    According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people's feelings.

    Finally, it just makes them greedier. “Higher wealth status seems to make you want even more, and that increased want leads you to bend the rules or break the rules to serve your self- interest,” said Paul Piff, lead scientist of the study.

    Piff pointed out that the findings don't mean that all rich people are untrustworthy or all poor people honest. He said the experiments were to show how people living in different social situations express their instincts（本能）and values in different ways.

福建省地处中国东南沿海，属于亚热带气候。森林覆盖率65.95%，继续位居全国首位，生态环境状况指数继续保持全国前列。福建全省环境质量持续保持优良，是水、大气、生态全优的省份之一。

    资料在2014年上海亚信峰会期间，中国石油与饿罗斯天然气工业股份公司签署了《中俄东线供气购销合同》，合同规定自签订合同的4-6年内，俄罗斯开始通过中俄天然气管道东线向中国供气，输气量逐年增长，最终达到每年380亿立方米，累计30年。半年之后，中俄双方签署了不具法律效力的西线合作备忘录和供气框架协议。协议显示，俄方将每年向中国供应300亿立方米天然气，为期30年。中俄东西两线在建成之后，向中国输入天然气680亿立方米／年，占到中国2020年天然气消费量的17%。

    Floods are second only to fire as the most common of all natural disasters.They occur almost everywhere in the world,resulting in widespread damage and even death.Consequently,scientists have long tried to perfect their ability to predict floods.So far,the best that scientists can do is to recognize the potential for flooding in certain conditions. There are a number of conditions,from deep snow on the ground to human error,which cause flooding.

    When deep snow melts it creates a large amount of water.Although deep snow alone rarely causes floods,when it occurs together with heavy rain and sudden warmer weather it can lead to serious flooding.If there is a fast snow melt on top of frozen or very wet ground,flooding is more likely to occur than when the ground is not frozen.Frozen ground or ground that is very wet cannot absorb the additional water created by the melting snow.Melting snow also contributes to high water levels in rivers and streams.

    Rivers that are covered in ice can also lead to flooding.When ice begins to melt,the surface of the ice cracks and breaks into large pieces.These pieces of ice move and float down the river,They can form a dam in the river,causing the water behind the dam to rise and flood the land upstream.If the dam breaks suddenly,then the large amount of water held behind the dam can flood the areas downstream too.

    Broken ice dams are not the only dam problems that can cause flooding.When a large human-made dam breaks or fails to hold the water collected behind it,the results can be devastating.Dams contain such huge amounts of water behind them that when sudden breaks occur,the great force of the water is like a great tidal wave.The dam waters can travel tens of kilometres,cover the ground in metres of mud and litter,and drown and crush every thing and creature in their path.

    Although scientists cannot always predict exactly when floods will occur,they do know a great deal about when floods are probably going to occur.Deep snow,ice-covered rivers,and weak dams are all strong conditions for potential flooding.
