China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

    Football, to me, is more than just a game. I have probably learned more than valuable lessons from it than from school.

    When I joined the team freshman year, I didn't realize what I was getting into. Even though I had been playing since fourth grade and knew it was hard work, nothing would prepare me for the effort I would put into football that year. We worked all summer in the weight room and ran on the track to get in physical and mental shape before the season.

    See, football is more of a mental sport than anything else, so running on the track wasn't only about getting in shape. We would push our minds by running as hard as we could even if we felt like we were going to pass out. At the beginning, I was immature（幼稚的）and only thought of myself, sometimes even giving up when I was tired or hurting. Then after the third game I had a season-ending injury. Imagine working all summer and then only being able to play three games! I needed an operation on my arm and at least five months to recover.

    After freshman year I decided that I would always give my best effort. Playing football in the college has taught me so much more than just what my tasks are on a particular play or how to block. I have learned to think about others first, and realized how important working hard is. Being with all my friends, even sweating and bleeding with them, really made us unite as a group of hard-working young men, who will succeed in life.

    Astronauts on shorter shuttle missions（使命）often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day's work.  This type of schedule is far too demanding for long missions on the International  Space Station（ISS）.  ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible . Weekends give the crew valuable.  Weekends give the crew valuable time to rest and do a few hours of  housework.  They can communicate with family and friends by email , internet phone and through Private video conferences.

    While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy . Before a mission. The family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for

    The astronauts to look at when they will be floating 370 kilometers above the Earth.  During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters . And as from early 2010, the internet became available on the ISS , giving astronauts the chance to do some “web surfing （冲浪）”in  their personal time.  Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.

    Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth's vast land mass and oceans.

    In the tenth grade, I began working for free at a vet's that was run by a friend. I wanted to get experience for what I thought would be my future job. However，on one particular Saturday morning I learnt something perhaps more important.

    The hospital was in the middle of one of the poorer sections of the city and some people could only pay for the most basic treatments. On this Saturday，a man and his young son，who was probably about 7 years old，walked in with a small cat in a cardboard box. There was something wrong with the cat's left eye. But the man could not afford to pay for the cost of the medicine. He kept quiet for a while，and then he asked where the nearest animal shelter was. Hearing this，his son cried and started to argue with him. All of a sudden，an older woman who was sitting in the waiting room stood up，walked up to the counter，and told the man that she would pay for the cost. The man thanked her and the son got to keep a healthy cat.

    I always thought it was the right thing to help out a needy person，but I only saw people do acts of kindness on TV or in movies. What the woman did made me believe that these things do happen in real life，and quite often.

    Now，when I can't decide whether to help someone who is in need，I remember this woman，and then I have the courage to step up to the plate. Sometimes other people follow.

    It is irrefutable: Parents, who talk to, read and engage with their very young children as often as possible, help them build literacy (读写能力) skills at an early age.

    Also certain: Parents of very young children usually have to do a lot of laundry. And low-income families tend to bring their kids with them to public laundromats (洗衣房).

    Those truths appear once a week at select neighborhood laundromats in Chicago. That's when librarians lay down colorful mats and oversized board books beside the industrial washing machines.

    Inside one of about 14 laundromats in the city's low-income neighborhoods, the librarians gather all available children for Laundromats Story Time (LST), a Chicago Public Library (CPL) program.

    With the noise of the washers and dryers, anywhere between a handful to more than a dozen children hear stories, sing songs and play games designed to help their brains develop. The event also aims to instruct parents on how to repeat the experience for their kids, working to raise poor literacy rates in underserved communities.

    "We read books, we sing songs, we do plays," says Becca Ruidl, the CPL's STEAM Team early learning manager, who runs the LST program. "We kind of keep it going so parents can walk in adn join in at any time. But a big part of what we do is model literacy skills for parents so they can do it at home with their kids."

    While a laundromat seems an unlikely place to engage with children, "we really wanted to meet people in the community where they're. "Ruidl says.

    And it clearly meets a need: Library officials say the program is in increasing demand, while Ruidl says families have adjusted their household's laundry day to suit the librarians' laundromat visits. At the same time, LST's co-sponsors—including a laundry industry trade group and Libraries Without Borders, an organization fighting poverty through literacy—have worked with the CPL to draft an instruction handbook to help expand the concept to other U.S. cities.
