As health care costs continue to rise, a growing number of companies are working out programs designed to keep their employees healthy.

    Thomas Chapple is the senior vice president. “It's really important to us because medical costs are going up like crazy,” he says. “This company spends more than $ 200 million a year on medical costs for its employees around the country. The best thing we have seen as a way to control the medical cost is individual fitness.”

    “We have a fitness center,” Shawn Flaherty, director of public relations for Freddie Mac., says. “We have a health benefits plan that encourages people to work out three times a week, get cholesterol （胆固醇）checks, as well as 'do not smoke.' If they do that, it will cost them less for the health benefits.”

    Rachelle Clark works for Freddie Mac. “I feel great. You know the benefit is rewarding. I like to look good and feel healthy. I am just fortunate that I work for the company that provides some type of facility for the employees.”

    While on-site fitness centers are popular, some companies pay membership fees at local gyms for employees. The companies also offer classes such as boxing, yoga and dancing. Employees see those health programs as a valuable benefit.

    Tom Brook exercises five days a week. As a newspaper reporter he has a tight schedule, although Tom says it's not that difficult for him to make time for a workout. “It is great. It is right here where we work,” says Tom. “So everybody gets a chance to use it whenever they want to. I have lost weight and never been in better shape.”

    The programs may not be a magic cure for rising health costs, but they seem to have a positive impact on both employers and employees.

    Doctors in Britain are worried because British teenagers eat lots of fried potatoes, sweets and fat food. Most teenagers don't have enough fruit or vegetables and more than one million British school children are overweight.

    Some teenagers say that they don't have time to eat good food, but kids who have a poor diet often have health problems when they are older.

    Americans have been with fast food for a long time, and it was born there. American fast food is now a part of life far beyond the stores of the United States. McDonald's, Pizza Hut, and KFC have restaurants all over the world.

    No one can say no to the fact that fast food at a fair price has its place around the world. It is popular now, and it is giving a hand to a country's economy (经济).

    A diet of hamburgers, fries and soda may seem happy, but it won't give your body things you need to stay healthy. Fast food has little of many important things our bodies need.

    Some parents are saying no to the fast food restaurants where people eat junk food and doctors are giving young people books and games about a good diet. Having a healthy and well-balanced diet can help you feel better and live longer.

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an ID number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says "The two things that change your life are the people you meet and books you read. BookCrossing combines both."

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back the "real" and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    It is estimated that more than half the world's population is bilingual (双语的), and in an increasingly globalised world, there are obvious benefits of speaking more than one language. However, for many years, parents were advised not to teach their children to speak more than one language from birth. Learning two or more languages simultaneously (同时) was believed to cause confusion and slow down academic development. While it is certainly true that children who are learning to speak more than one language as their mother tongue will often mix the languages up or speak a little later, these are temporary problems, and there is no reason to avoid teaching a child more than one language.

    In fact, there are plenty of reasons to encourage your child to become bilingual from birth. As well as the obvious benefits of being able to communicate with more people, and the possibility of earning more money, children who speak more than one language have been shown to score more highly in achievement tests at school. This is true for mathematics as well as tests of verbal (言语的) skills.

    And in later life it has been found that bilinguals, on average, will tend to develop Alzheimer's disease five years later than monolingual speakers. Speaking three or more languages offers even more protection. It seems that the increased number of connections within the brain allows bilinguals to cope better with brain damage.

    But is it too late if you haven't already learned a second language in childhood? It used to be thought that the adult brain was very fixed, but recent research has shown that we continue to develop new connections in the brain throughout our lives, meaning that it's perfectly possible to learn another language to a high standard. Older learners are less likely to have native-like pronunciation, but they are better at learning vocabulary as they are able to use far more skills and strategies than children. And learning a language is like using a muscle – the more you use it, the stronger it gets, meaning that you will find your third language easier than your second, and so on.

    While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be "taught" by a digital teacher, Will. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar(化身) that turns up on the students' desktop, tablet, or smartphone screen when called.

    Thanks to a digital camera and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal signals. For example, if a student smiles at Will, he responds by smiling back. This two-way communication not only helps draw the students' attention, but also allows the program's developers to monitor their involvement(参与) and make changes if needed.

    Vector's Chief Digital Officer, Nikhil Ravishankar, believes that Will-like avatars could be a novel way to attract the attention of the next generation. He says, "Using a digital human is a very popular method to deliver new information to people, and I have a lot of hope in this technology as a means to deliver rich and educational experience in the future." Greg Cross, the Chief Business Officer for Soul Machines, states that kids who have grown up in this digital time adapt(适应) to new technology quickly, and he hopes to develop the idea of digital humans in the area of educate further.

    The program, in place since August 2018, has been a great success so far. However, no mater how popular it becomes, Will is unlikely to replace human educators any time soon. For one, the avatar's knowledge base is severely limited. But more importantly, even the smartest digital avatars could never predict and react to all the unexpected situations that educators have to deal with on a daily basis. However, it could come in handy as a "personal teacher", providing kids with one-on-one help on the subjects or even topics.

    At least 20 people died and hundreds were injured in a bridge collapse in the eastern Indian city of Kolkata Thursday. Witnesses said many people and vehicles, including two buses carrying more than 100 passengers, were under the bridge when it fell. They also said construction workers had set up camps near the bridge site where they would sleep and cook.

    Before rescue teams arrived, local residents and firefighters used their bare hands to try to rescue people trapped under the debris. The collapsed bridge is in a busy commercial area of Kolkata. Its location has made it difficult for rescue operations. Access to the area is blocked on both sides by buildings, and the streets are blocked with heavy traffic.

    Reuters (路透社) reports that the Chief Minister of West Bengal, Mamata Banerjee, rushed to the scene of the collapse. She said that rescuing those trapped is her “top priority”. Banerjee said those responsible for the disaster will be punished. Yet she faces questions about the safety of the construction project. The Telegraph newspaper reported last November that Banerjee wanted the bridge — already five years overdue — to be completed by February. Project engineers said they were concerned over whether this would be possible, the newspaper said at the time. Construction workers had been on a strict schedule to complete the bridge. The disaster could affect the West Bengal election next month. An Indian company, IVRCL, was building the 2­kilometer bridge, its website said. IVRCL's director of operations said the company was not sure of the cause of the disaster.
