For a long time, the traditional method of identifying liars was to watch their body language, including facial expressions.

    What if the person appears to be nervous? Is the person unable to look me in the eye? Is he or she look around the room? What about other nervous movements, such as fidgeting（坐立不安）or shifting from side to side? Many people—from parents to police officers and airport security personnel—depend on this method. But does a person's body and face reveal the truth? Not according to a new study.

    Talking, it seems, is the best way to smoke out a liar. That is what researchers in the United Kingdom found out recently. Their investigation took place at one place where lying can get you into big trouble—an airport.

    The researchers asked volunteers to pretend they were real passengers and then lie to airport security agents. Some of the agents used spoke conversation-based methods to question these make-believe passengers. Others depended instead on the person's body language, like lack of eye contact and showing signs of nervousness. The agents talking with the passengers were 20 times more likely to catch the liars. The study found that these conversation-based techniques can help you recognize when a person is lying to you. Like many methods, this conversation method has a name. It is called Controlled Cognitive Engagement or CCE, for short.

    The British government partly financed this study. The American Psychological (APA) published the findings. Body language cannot be trusted. Using body language and facial expressions to catch someone in a lie is really hard. And it only works, seemingly, by chance.

    Thomas Ormerod is the head of the School of Psychology at the University of Sussex in England. On the APA website, he reported that the “suspicious-signs method”—or using body language—“almost completely fails” in finding lies.

    One form of social prejudice against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games, going on the Net and downloading MP3s are only for the youngsters. Isn't it unfair that older people enjoying a computer game should be frowned（皱眉）upon by their children and grandchildren?

    Nowadays older people have more control over their lives and they play a full part in society. Moreover, better health care has left more people in their sixties and seventies feeling fit and active after retirement. Mental activity, as well as physical exercise, can contribute to better health. Playing computer games is a very effective way of exercising the brain.

    When personal computers were first introduced, most older people didn't believe they would ever familiarize themselves with it. Now computers have been around for a few generations and retired people have gradually become more relaxed about using them for fun. Gamers over 65 prefer playing puzzle games and card games. Kate Stevens, aged 72, says: 揑 find it very relaxing. It's not very demanding, but you still need to concentrate.”

    Another development that has favored 揼rey games? is a change in the type of videogames available on the market. There's a greater variety of games to choose from, including more intellectual and complex strategy（策略）and simulation（模拟）games. Internet Chess and Train Simulator are among the most popular of these. Train Simulator is based on real-world rail activities. Players can choose from a variety of challengers, such as keeping to a strict-timetable and using helper engines during a winter storm.

    Some people argue that 揼rey gamers? simply don't have the skills required for computer games, and that teenagers are better. This couldn't be further from the truth. Most computer games require the kind of analytical thinking that improves with practice, which means that the 揼rey gamers may well be far better than gamers half a century younger than them.

    Driving is absolutely a necessary skill in today's world. What you need before you master it is a driving license（驾驶执照）. {#blank#}1{#/blank#} But before it becomes a time saver, it is a very time-consuming （耗时的） thing. Without proper practice you cannot learn this skill.

    First of all, for lack of driving knowledge or skills, many people die of road accidents every year. {#blank#}2{#/blank#}If you are brave and scream “I would”, then I highly advise you to reconsider your attitude towards driving.

If you have enough money, you can take practical lessons or the ones that take place in a classroom. {#blank#}4{#/blank#} Free materials about driving are easy to find on the Internet. Remember that practical experience is a must if you are serious about your health and safety.

    Sports can help us a lot. Taking exercises can make us strong. In collective（集体的）sports like basketball, volleyball or football, we will learn the importance of cooperation(合作). And sports can also help us relax after work or study.

    However, as the saying goes, "there are two sides of everything." Sometimes we may hurt other players or ourselves if we are not careful enough when participating(参加) in sports activities. What's more, too much or hard practice can be bad for our health.

    Sports can make us healthy both physically and psychologically(心理地). It is also a good way for people to know each other and can improve friendship between people. So long as we are careful enough, sports can do us nothing but good.
