Eco City Farms(生态城市农场) are becoming more popular in cities and towns around the Unites States.
Eco City Farms in Edmonton, Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a working-class community(社区). People do not have very much money. And they have limited access to fresh food in markets.
Over the past two years, the farm has attracted volunteers from the community like Marcy Clark. She schools her four children at home. On a recent day she brought them to Eco City Farms for a lesson. Her son Alston Clark thinks his experience is very valuable.“I like coming out here,”he says,“You know, you connect with the earth, where your food comes from. You appreciate the food a little bit more.”
Margaret Morgan started Eco City Farms. She thinks of it as a place where people can learn to live healthier lives. “Growing food in a community brings people together,”she continues,“Every piece of what we do here is a demonstration(示范) to show people everything about how to have an eco-friendly community.”she says. From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees, but improving the soil with compost(肥料)made from food waste.
Eco City Farms is an experimental operation. The farm gets its power not from the local electricity networks, but from the sun with solar panels. In winter, the green house use a geothermal(地热)system.
Vegetables can be grown all year. So once a week, all winter long, neighbors like Chris Moss and her three children bike to the farm to pick up a share of the harvest.

Almost every day, we discuss the topic of health, especially for kids. But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Let's read the following rules. They can help you stay healthy.
① Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition(营养) we need by eating different kinds of food, especially fruit and vegetables.
② Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium(钙) to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important nutrition.

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．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 |
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 |
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． |

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．

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．What is Paragraph 2 mainly about?
| A．How blue light exposure affects hunger． |
| B．Why blue light exposure influences sleepiness． |
