On April 20,2013, a big and powerful earthquake attacked Ya’an, Sichuan Province. A great many buildings and houses collapsed, a lot of people were killed and even more people lost their homes in the earthquake .
Death toll from the 7.0-magnitude earthquake that hit Ya’an in southwestern China's Sichuan Province has risen to 188 (as of 18:00 pm, April 22, ), according to latest calculations by local Civil Affairs Bureau. At least 11,826 were reportedly injured in the quake while 25 are still missing, the bureau said.
Experts are anticipating much less casualties in the quake than that from the 8.0 magnitude quake hit Wenchuan on May 12, 2008, also in Sichuan Province, which killed more than 80,000 and injured over 300,000.
Energy released from Wenchuan earthquake would be 30 times of that from Ya’an quake, according to Zhang Xiaonan, an expert with China's Geophysical Union. Dai Junwu with Harbin-based seismological bureau expects the death toll at less than 1,000, and economic losses from the quake could reach up to 100 billion yuan.
Police and expert teams have already rushed for rescue in the quick stricken areas, and the State Council has banned unauthorized rescue efforts and individual vehicles from going to the quake zone to avoid congestion(交通阻塞).
Rescue efforts were carried “timely and orderly”, said Chinese Premier Li Keqiang who flew to the quicken-stricken area on Sunday, the second day of the quake. He was quoted as saying that “the current priority is to save lives”.When did Ya’an earthquake occur?

Children as young as ten are becoming dependent on social media for their sense of self﹣worth， a major study warned．
It found many youngsters（少年）now measure their status by how much public approval they get online， often through "like"． Some change their behavior in real life to improve their image on the web．
The report into youngsters aged from 8 to 12 was carried out by Children's Commissioner （专员）Anne Longfield． She said social media firms were exposing children to major emotional risks，with some youngsters starting secondary school ill﹣equipped to cope with the tremendous pressure they faced online．
Some social apps were popular among the children even though they supposedly require users to be at least 13．The youngsters admitted planning trips around potential photo﹣opportunities and then messaging friends﹣and friends of friends﹣to demand "likes" for their online posts．
The report found that youngsters felt their friendships could be at risk if they did not respond to social media posts quickly， and around the clock．
Children aged 8 to 10 were "starting to feel happy" when others liked their posts． However，those in the 10 to 12 age group were "concerned with how many people like their posts"， suggesting a "need" for social recognition that gets stronger the older they become．
Miss Longfield warned that a generation of children risked growing up "worried about their appearance and image as a result of the unrealistic lifestyles they follow on platforms， and increasingly anxious about switching off due to the constant demands of social media"．
She said： "Children are using social media with family and friends and to play games when they are in primary school． But what starts as fun usage of apps turns into tremendous pressure in real social media interaction at secondary school．"
As their world expanded． she said，children compared themselves to others online in a way that was "hugely damaging in terms of their self﹣identity， in terms of their confidence， but also in terms of their ability to develop themselves"．
Miss Longfield added： "Then there is this push to connect﹣if you go offline， will you miss something， will you miss out， will you show that you don't care about those people you are following，all of those come together in a huge way at once．"
"For children it is very， very difficult to cope with emotionally．" The Children's Commissioner for England's study﹣Life in Likes﹣found that children as young as 8 were using social media platforms largely for play．
However， the research﹣involving eight groups of 32 children aged 8 to 12﹣suggested that as they headed toward their teens， they became increasingly anxious online．
By the time they started secondary school﹣at age 11﹣children were already far more aware of their image online and felt under huge pressure to ensure their posts were popular， the report found．
However， they still did not know how to cope with mean﹣spirited jokes， or the sense of incompetence they might feel if they compared themselves to celebrities（名人）or more brilliant friends online． The report said they also faced pressure to respond to messages at all hours of the day﹣especially at secondary school when more youngsters have mobile phones．
The Children's Commissioner said schools and parents must now do more to prepare children for the emotional minefield（雷区）they faced online． And she said social media companies must also "take more responsibility"． They should either monitor their websites better so that children do not sign up too early， or they should adjust their websites to the needs of younger users．
Javed Khan， of children's charity Bamardo's， said： "It's vital that new compulsory age﹣appropriate relationship and sex education lessons in England should help equip children to deal with the growing demands of social media．
"It's also hugely important for parents to know which apps their children are using．"

If you want to disturb the car industry， you'd better have a few billion dollars： Mom﹣and﹣pop carmakers are unlikely to beat the biggest car companies． But in agriculture， small farmers can get the best of the major players． By connecting directly with customers， and by responding quickly to changes in the markets as well as in the ecosystems（生态系统）， small farmers can keep one step ahead of the big guys． As the co﹣founder of the National Young Farmers Coalition （NYFC， 美国青年农会）and a family farmer myself， I have a front﹣row seat to the innovations among small farmers that are transforming the industry．
For example， take the Quick Cut Greens Harvester， a tool developed just a couple of years ago by a young farmer， Jonathan Dysinger， in Tennessee， with a small loan from a local Slow Money group． It enables small﹣scale farmers to harvest 175 pounds of green vegetables per hour﹣a huge improvement over harvesting just a few dozen pounds by hand﹣suddenly making it possible for the little guys to compete with large farms of California． Before the tool came out， small farmers couldn't touch the price per pound offered by California farms． But now， with the combination of a better price point and a generally fresher product， they can stay in business．
The sustainable success of small farmers， though， won't happen without fundamental changes to the industry． One crucial factor is secure access to land． Competition from investors，developers， and established large farmers makes owning one's own land unattainable for many new farmers．From 2004 to 2013， agricultural land values doubled， and they continue to rise in many regions．
Another challenge for more than a million of the most qualified farm workers and managers is a non﹣existent path to citizenship ﹣ the greatest barrier to building a farm of their own． With farmers over the age of 65 outnumbering（多于）farmers younger than 35 by six to one， and with two﹣thirds of the nation's farmland in need of a new farmer， we must clear the path for talented people willing to grow the nation's food．
There are solutions that could light a path toward a more sustainable and fair farm economy，but farmers can't clumsily put them together before us． We at the NYFC need broad support as we urge Congress to increase farmland conservation， as we push for immigration reform， and as we seek policies that will ensure the success of a diverse and ambitious next generation of farmers from all backgrounds． With a new farm bill to be debated in Congress， consumers must take a stand with young farmers．

In the 1760s， Mathurin Roze opened a series of shops that boasted（享有）a special meat soup called consommé． Although the main attraction was the soup， Roze's chain shops also set a new standard for dining out， which helped to establish Roze as the inventor of the modern restaurant．
Today， scholars have generated large amounts of instructive research about restaurants． Take visual hints that influence what we eat： diners served themselves about 20 percent more pasta（意大利面食）when their plates matched their food． When a dark﹣colored cake was served on a black plate rather than a white one， customers recognized it as sweeter and more tasty．
Lighting matters， too． When Berlin restaurant customers ate in darkness， they couldn't tell how much they'd had： those given extra﹣large shares ate more than everyone else， but were none the wiser﹣they didn't feel fuller， and they were just as ready for dessert．
Time is money， but that principle means different things for different types of restaurants． Unlike fast﹣food places． fine dining shops prefer customers to stay longer and spend． One way to encourage customers to stay and order that extra round： put on some Mozart（莫扎特）．When classical， rather than pop， music was playing， diners spent more． Fast music hurried diners out．
Particular scents also have an effect： diners who got the scent of lavender（薰衣草）stayed longer and spent more than those who smelled lemon， or no scent．
Meanwhile， things that you might expect to discourage spending﹣"bad" tables， crowding．high prices﹣don't necessarily． Diners at bad tables﹣next to the kitchen door， say﹣spent nearly as much as others but soon fled． It can be concluded that restaurant keepers need not "be overly concerned about 'bad' tables，" given that they're profitable． As for crowds， a Hong Kong study found that they increased a restaurant's reputation， suggesting great food at fair prices． And doubling a buffet's price led customers to say that its pizza was 11 percent tastier．

| A． |

| B． |

Composite image of Europe and North Africa at night， 2016． Credit： NASA Earth Observatory images by Joshua Stevens， using Suomi NPP VIIRS data from Miguel Roman， NASA's Goddard Space Flight Center． Artificial light is often seen as a sign of progress： the march of civilization shines a light in the dark； it takes back the night； it illuminates． But a chorus of scientists and advocates argues that unnaturally bright nights are bad not just for astronomers but also for nocturnal （夜间活动的） animals and even for human health．
Now research shows the night is getting even brighter． From 2012 to 2016 the earth's artificially lit area expanded by an estimated 2.2 percent a year （map）， according to a study published last November in Science Advances． Even that increase may understate the problem， however． The measurement excludes light from most of the energy﹣efficient LED lamps that have been replacing sodium﹣vapor technology in cities all over the world， says lead study author Christopher Kyb， a postdoctoral researcher at the German Research Center for Geosciences in Potsdam．
The new data came from a NASA satellite instrument called the Visible Infrared Imaging Radiometer Suite （VIIRS）． It can measure long﹣wavelengths of light， such as those produced by traditional yellow﹣and﹣orange sodium﹣vapor street lamps． But VIRS cannot see the short﹣wavelength blue light produced by white LEDs． This light has been shown to disrupt human sleep cycles and nocturnal animals' behavior．
Credit： Mapping Specialists： Source： "Artificially Lit Surface of Earth at Night Increasing in Radiance and Extent．" by Christopher C． M． Kyba et al． in Science Advances， Vol． 3． No 11， Article No， E1701528； November 22， 2017．
The team believes the ongoing switch to LEDs caused already bright countries such as Italy， the Netherlands， Spain and the U． S． to register as having stable levels of illumination in the VIIRS data． In contrast， most nations in South America， Africa and Asia brightened， suggesting increases in the use of traditional lighting． Australia actually appeared to lose lit area but the researchers say that is because wildfires skewed the data．
"The fact that VIIRS finds an increase （in many countries）， despite its blindness in the part of the spectrum that increased more， is very sad，" says Fabiofalchi， a researcher at Italy's Light Pollution Science and Technology Institute， who did not participate in the study． In 2016 Falchi， along with Kyba and several other members of his research team， published a global atlas of artificial lighting that showed one third of the world's population currently lives under skies too bright to see the Milky Way at night．
The data also cast doubt on the idea that the LED lighting revolution will lead to energy cost savings． Between 2012 and 2016 the median nation pumped out 15 percent more long﹣wavelength light as its GDP increased by 13 percent． And overall， countries' total light production correlated with their GDP． In other words， Kyba says， "we buy as much light as we are willing to spend money on．"
