Using a computer or smartphone at night can cause us to pile on the pounds，new research has revealed．
The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger．It found that exposure to blue light increases hunger levels for several houus and even increases hunger levels after eating a meal．Blue light exposure has also already been shown to cause decreased sleepiness in the evening，increasing the risk of sleeplessness．
The leading researcher，Ivy Cheung，from Northwestern University in Chicago，said，“A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism(新陈代谢)．These results are important because they suggest that controlling environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism．”
The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim(昏暗的)light conditions，which involved exposure to less than 20 lux(勒克斯，照明单位)during 16 hours awake and less than 3 lux during eight hours of sleep．On the third day they were exposed to three hours of 260 lux，blue-enriched light starting10.5 hours after waking up, and the effects were compared with dim light exposure.
Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure，hunger and metabolism．

Economists have studied how markets work for a long time．Generally，they work well．But markets do not always perform as expected．Jean Tirole of France won the Nobel Prize in Economics for studying why markets are imperfect，or inefficient，and what governments can do to regulate them．
The Nobel prize committee announced the $1．1 million prize in Stockholm to Jean Tirole．It called Mr.Tirole“one of the most influential economists of our time”．The organization said he had done important research in a number of areas．But it said，“most of all he has clarified how to understand and regulate industries with only a few powerful firms．”
Mr．Tiro1e works at the Toulouse School of Economics in Toulouse，France．He is 61 years old．For about 30 years，Mr．Tirole has researched periods when markets failed，that is，when they did not provide good results in price and competition．He looked at how a small number of large companies，or even a single company，can strongly influence industries. Banking and telecommunications were among the industries he studied．
The Nobel committee said that unregulated markets often produce socially undesirable results. They can result in higher prices or companies that use their market position to block others· The committee said it chose Mr．Timle because he thought about how best to regulate markets．For example，Tore Ellingsen，Chairman of the committee that awards the economics prize，says Mr·Tirole showed the need to develop better rules for the banking industry．This became urgent after the world financial crisis of 2008—2009．
The economics Drize is called the Bank of Sweden Prize in Economic Sciences in Memory of Alflred Nobel．Alfred Nobel did not establish the prize．It was first presented in 1969．

Ever feel like there aren’t enough hours in the day?A group of time-challenged Canadian women are wishing for a 25-hour clock．
Jessie Behan，president of the 25th Hour Coalition(联盟)which is a group of Canadian women who have changed to a longer day，said the struggle for women to maintain work-1ife balance motivated her to research the body’s natural clock．“Many of my girlfriends are having kids，getting married，and I see the sufferings of dealing all that when you’re a working woman，”she said．“Women like myself are sick of living their lives by a 24-hour clock．”
A 2007 study by Charles Czeisler found a switch to longer days could be beneficial，especially for frequent travelers，shift workers，astronauts and those who experience trouble sleeping or waking．
In a similar study，Czeisler showed the body’s natural clock averages 24 hours and 11 minutes in both young and older people．The current 360-degree clock has 720 minutes，giving each minute 0．5 degree．With the new 25-hour day，30 minutes is added to each 12-hour period making each minute 0.48 degree．
While still a relatively small movement—the 25th Hour Coalition has 160 Facebook members，Behan is hoping for large changes．“The goal is to get as many women on board；there’s no harm in just trying it out and seeing．If it gets big，maybe the government will decide to standardize it．”
A recent online survey by Reader's Digest，which included 150 people in each of the 13 countries，suggests it's not just Canadians looking for longer days．Readers were asked“what would you do with an extra hour”if given a choice between sleep，work，exercise and family time．In Spain，half of respondents(被访者)said they’d like an extra hour in the day to devote to family time．The same was found for respondents in Brazil，the US and Britain，who chose family time over sleep，which came in at a close second．Only in India did work top the list with 50 percent of respondents claiming they could use an extra hour at the office．
1.Some Canadian working women are campaigning for the 25-hour day in order to_______．
A．have more chances at work
B．keep a balance between life and work
C．experience something new
D．have a better sleep
2.Jessie Behan want more women to join the 25 th Hour Coalition because she________．
A．intends to make more Facebook friends
B．hopes to get benefits from more people
C．considers it is harmless to form such an organization
D．thinks it can help those women to realize their dreams
3.What is implied in the last paragraph?
A．Respondents from most nations want more family time．
B．Respondents from developed countries experience more stress．
C．Most Canadian respondents claim that they need more family time．
D．Indians are the most hardworking of the 13 nations．

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
THINK“ADDING VALUE”(and you’11 get more money)
Most people either“like”their job，“love”their job or“hate”their job．Everyone wants to make more money regardless of how they feel about their job．The secret to making more money is，focus on adding value．Think less of what you can have or acquire．1. You don’t always have to do more though we always can do more．What you might consider is“doing different”．Let me explain．
1．Do you choose to be happy at work?It’s a choice．And you can do it．It’s a lot of“mind over matter”．Mind what’s important and the rest doesn’t matter． 2. When you choose to be happy，you will affect others in the workplace．
2． 3. Michael’s definition of a“drag”is，a person who“drastically reduces all good．”Of course，they have a bad attitude．If you’re this kind of person，you can change．Start being positive．Start by giving subtle and honest praise to co-workers．Just start looking for authentic reasons to give others some praise．It will set you apart from everyone else．People will recognize you as being more caring and more interested in them．Your influence will skyrocket especially if you’re in an environment where there is little praise and encouragement．
3．CHOOSE what you are going to think．Most people have given in to CNN，ABC，NBC，“the way things are”，society，drama，negativity and the like．It’s time to take back charge of your brain．Get your focus directed．Like Paul said in the bible，“Think on these things．Things that are true，are of a good report，are honorable，are positive．” 4. If you have nothing to read that is positive，send me your email address and I'll send you a free copy of my‘Powerful Attitudes’ebook．Read a little every morning．It will positively and powerfully affect the rest of your day．
When you change yourself，you will add value in your workplace．Like the late great business philosopher，Jim Rohn said，“You can take out the garbage at McDonalds and earn minimum wage．But if you take out the garbage and whistle as you do it every day，you’re likely to earn 50 cents more per hour．”Add value to your workplace by controlling your own attitude． 5.
A．Start your day by reading something positive．
B．Think more of what you can do，produce or create．
C．Just be yourself and create a strong self image．
D．Are you a“drag”?
E．Your attitude and your happiness is important．
F．Fall in love with it．
G．You will advance faster and in time，make a lot more money．
