Siri is an artificial intelligence (AI) that you can carry around in the pocket, where it waits patiently to be told what to do. In the week we spend together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop.

    A typical command might be: “Reserve a table for two at a good French restaurant in San Francisco.” Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger. In some ways Siri is just a fancy program to the 35 websites it can connect to, from taxi booking websites to movie review databases (数据库). But what's new is the way it can analyze the intentions of its users and use those sites to put them into action.

    Siri attaches possibilities to the explanation of each word and compare your location with other data, some of which you must provide yourself. To send email reminders, Siri obviously needs to know your email address. To “find me the flower shop closest to work”, it needs to know where you work. To pay bills or buy airline tickets, it would need to be linked to your credit card.

    That raises the question of how far we are willing to trust a piece of software that can go and do things for us based on what it “thinks” we mean. Siri may be simple, and always shows its explanation of a command before carrying it out. But it gives users a preview of a new balance between privacy, trust and convenience that the expansion of AI into everyday life is likely to develop.

    The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named “DriveLAB” in order to understand the challenges faced by older drivers and to discover where the key stress points are.

    Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated(隔绝) and inactive.

    Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.

    These include custom-made navigation(导航) tools, night vision systems and intelligent speed adaptations. Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.”

    “But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.”

    Dr Amy Guo, the leading researcher on the older driver study, explains, “The DriveLAB is helping us to understand what the key points and difficulties are for older drivers and how we might use technology to address these problems. “For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We're looking at the benefits of systems which control their speed as a way of preventing that.

    “We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel.”

    Can you imagine four hours of your day getting to and from work? For the last eight years, Jo Meade rode her bike each Sunday on a 16-mile round trip to her job washing dishes. It took more than an hour each way. Other days of the week she would spend two hours on three buses from her apartment to get to the other work, for a four-hour round trip.

    That was the “before” part of her life. The “after” part of her life was started by the community Police Officer Trevor Arnold, who delivered a used car to her with the help of a car dealer and other donors.

    Arnold, who spotted Meade, red and sweaty, riding her bike in the worst heat this summer, decided he would het her a car. He intended to quietly buy her a used car out of his own pocket so he turned to his friend Kody Slaght, a car salesman to ask about a car priced $1,000. That wasn't enough for a reliable ride, Slaght said, but the dealership said they would find a good car for her at a good price. Soon others were donating. Slaght and Arnold wouldn't say how much the car cost, but the value is about $4,000.

    Arnold said he was motivated by Meade's work ethic（职业道德）to help. “I see a lot of hardworking people nut that's when they are at work. Can you imagine spending four hours of your day getting to and from work?” he said.

    Meade's boss said she was awesome and really reliable when she worked and she got along with others. “She's willing to rise the three buses to get in here on her day off if we need her too.”

    Meade said she was planning to buy a car, “but I haven't been able to afford it,” she said. “Trevor, he is a very good guy. I did not expect this.”

    People need to relax and enjoy themselves. One way they can have a good time is to watch a baseball game or another sports event. Even thousands of years ago, groups of people gathered to watch skilled athletes (运动员).

    Over 2000 years ago in Greece, certain days in the year were festival days. These were holidays when people stopped work and enjoyed themselves. They liked to watch athletes take part in races and other games of skill.

The most important festival was held every four years at the town of Olympia. It was held in honor of the Greek god Zeus (宙斯). For five days, athletes from all parts of the Greek world took part in the Olympic Games. At the Olympic Games, people could watch them box, run, jump and so on. There was a relay race between two teams of men in which a lighted torch (火矩) was passed from runner to runner. The Olympic Games were thought to be so important that cities which were at war with one another had to stop fighting. People were allowed to travel to the games safely. Thousands of people came to Olympia from cities in Greece and from her colonies (殖民地) in Africa, Asia and Italy. They met as friends to cheer their favorite athletes and to enjoy themselves.
