In beautiful rural Montana lies the town of Livingston. Around half the students in the Livingston School District qualify for free or reduced-price lunches, according to local educator Rachael Jones, known as “Farmer Jones”. She is the director of the Livingston Farm to School program, which uses the district’s two greenhouses and four gardens to grow food that supplements (补充) school meals while offering kids hands-on lessons. Jones said, “In many places around the country, if you can’t pay for your school meal, you don’t eat. Well, here, we don’t turn anyone away.”

The town’s school district and community members started the program eight years ago. It was part of the National Farm to School Network, which aims to increase access to local food and nutrition education across the country. Jones, who attended public school in Livingston as a kid, has headed up the local program since 2014. Farm to School enriches curriculums in all of the schools through garden lessons, cafeteria and kitchen lessons, and classroom lessons.

Research has shown that healthy school meals can better academic performance, including improved test scores. Though the Farm to School program is not aimed only at lower-income students, Jones said, “Such kids are more likely to eat lunch provided by the school.” Eventually she wants to get healthy, affordable meals on the plate of every child in Livingston.

It is important for kids to understand where their food comes from. That’s a life-changing experience for them. Jones said, “When I grew up a big force in my life was my grandma Ethel. She taught me from a really early age the value of growing my own food. I worked in her gardens with her and somehow, through all of those experiences—eating her tomatoes and canning pickles (泡菜) with her—it really built up my trust and knowledge in food systems. I’m so thankful to her!”

Cortana, Alexa ,Siri ,These are names of robotic voices that are often programmed on electronic tablets. They also become default (默认) identities for people with speech disorders who rely on technology to communicate. Now some speech scientists are developing personalized voices to reflect the broader diversity of the people who use them. To do it, they are tapping into a vast network of volunteers who are donating their voices to share with people who can’t speak.

The effort to build an international “Human Voicebank” has attracted more than 17,000 volunteers from 110 countries, including Priyanka Pandya, a 16-year-old from Columbia, Md., who plans to spend her winter vacation recording a string of sentences into her computer “To be able to give somebody the gift of voice, I think that’s really, really powerful,” she said.

“Everyone has a voice,” said Rupal Patel, founder of VocaliD, the company that started the voicebank. “Even people who are unable to speak have sounds that are unique to them.” Her company designs personalized voices by recording the unique sounds of the user, and then mixing them with 6 to 10 hours of recordings from a voice donor, matched by age, gender and region. The company is developing voices now for its first 100 customers.

Also, people’s voices change. The company is looking for donors who are willing to record their voices, and then record them again a few years later, as they get older.

Some of the first customers say they are happy with the results, John A. Gregoire was one of the first customers to receive a personalized voice from Vocalid last December. The voice came eight years after he developed ALS (肌萎缩侧索硬化症) and more than six years have passed since his voice became unintelligible to everyone except his wife and youngest son. “Having a distinctive voice is like getting something back that was stolen.” John said.

Pigeons in London have a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.

“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is, and how it actually affects their health.” London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing(引用)a report released by the city manager last year. If people were better informed about the pollution they’ re breathing, she says, they could pressure the government to do something about it.

Nearby, on a windy hill in London’s Regent’s Park, an experiment is underway that could help—the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, from France, chose the problem of air pollution.

“Basically, I realized how important the problem was,” he says.   “But also I realized that most of the people around me didn’t know anything about it.” Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.

“So”, he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones were his first thought. But it’s illegal to fly them over London. “But pigeons can fly above London, right?” he says. “They live—actually, they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low.”

So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city’s air.

Earlier this year I removed all Internet services from my home, which was very upsetting at first.     16    

I was not content with the time I was wasting—I felt I could spend it in doing more purposeful things than on the Internet. If there is something I want to research on the Internet, I write it down and use that list when I have access to the Internet.     17    . I’ll go to the office, the library, the coffee shop or some other places with free public Wi-Fi, and work on what I need to do online.

    18    . I use the Internet with the intention of doing things such as logging on to watch some You Tube videos or laughing at funny pictures. Whenever I’m on the Internet now, I use it in a deliberate way that benefits me and adds value.

    19    . I could focus on writing without being disturbed. I have more time to read, to write, to think, to exercise and to walk. Because I’m out of the house, I meet new people. Additionally, I have more time for friends and I feel less stressed and my thoughts are clearer. My mind is more focused on important things.     20    . Plus, I no longer long for the Internet like I once did.

The airplane maker Airbus has announced plans     41     (quit) making its famous A380 airplane. The A380 is the world’s largest passenger airplane and     42     (be) in service for 12 years.

Airbus decided to stop     44     (produce) of the 541-seat A380. The decision was due to sales that were not     45     satisfying as expected. Airbus said it would no longer build the A380 in 2021.

However, booming air travel brought the demand for twin-engine planes that can fly non-stop to     49     people want to travel. An Airbus spokesperson said the A380 was a “passenger magnet”, and he was     50     (disappoint) that airlines misunderstood and marketed it poorly.
