6．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 habor．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 20centimeters（8inches） over the past 135years．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 45tide 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 30centimeters（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 1957to 1963，the city experienced troublesome floods an average of 4.6days per year．Bur from 2007to 2013，the occurring rate of troublesome floods jumped five times．Annapolis city was even more serious．From 1957to 1963，troublesome floods were roughly 3.8days per year．From 2007to 2013，the average was 10times 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．"

3．Quiet Virtue：The Conscientious
The everyday signs of conscientiousness （认真尽责）-being punctual，careful in doing work，self-disciplined，and scrupulous （一丝不苟的） in attending to responsibilities-are typical characteristics of the model organizational citizen，the people who keep things running as they should．They follow the rules，help out，and are concerned about the people they work with．It's the conscientious worker who helps newcomers or updates people who return after an absence，who gets to work on time and never abuses sick leaves，who always gets things done on deadline．
Conscientiousness is a key to success in any field．In studies of job performance，outstanding effectiveness for almost all jobs，from semi鄄skilled labor to sales and management，depends on conscientiousness．It is particularly important for outstanding performance in jobs at the lower levels of an organization：the secretary whose message taking is perfect，the delivery truck driver who is always on time．
Among sales representatives for a large American car manufacturer，those who were most conscientious had the largest volume of sales．Conscientiousness also offers a buffer （缓冲） against the threat of job loss in today's constantly changing market，because employees with this quality are among the most valued．For the sales representatives，their level of conscientiousness mattered almost as much as their sales in determining who stayed on．
There is an air around highly conscientious people that makes them seem even better than they actually are．Their reputation for dependability influences managers爷evaluations of their work，giving them higher evaluations than objective measures of their performance would predict．
But conscientiousness in the absence of social skills can lead to problems．Since conscientious people demand so much of themselves，they can hold other people to their own standards，and so be overly judgmental when others don爷t show the same high levels of model behavior．Factory workers in Great Britain and the United States who were extremely conscientious，for example，tended to criticize co-workers even about failures that seemed unimportant to those they criticized，which damaged their relationships．
When conscientiousness takes the form of living up to expectations，it can discourage creativity．In creative professions like art or advertising，openness to wild ideas and spontaneity （自发性） are scarce and in demand．Success in such occupations calls for a balance，however； without enough conscientiousness to follow through，people become mere dreamers，with nothing to show for their imaginativeness．
