The American believe that anybody can become President of the United States. In a recent Hollyhood comedy(喜剧), that is exactly what happens.

    Dave Kovic, played by Kevin Kline, is a kind-hearted man who runs a business that finds people jobs. He leads a typical(典型的) American way of life, except for one thing— he looks exactly like the President, Bill Mitchell. In fact, the only thing that makes him different from the nation's leader is that he is very nice!

    The president has started using look-alikes during some public appearance. Dave is offered a chance to “serve his country” by becoming one. However, things go wrong. The President becomes very ill and Dave ends up acting as the President forever.

    Director Ivan Reitman, who made the popular and successful comedies like Twins, Ghostbusters and Legal Eagles, could have gone for easy laughs by making fun of the American government. Instead, Dave is an attractive comedy about an ordinary man in extraordinary situations. Kevin Kline gives a double performance as Dave and the President, and Sigourney Weaver is at her best as his First Lady. The love story that develops between her role and Dave is a real classic(经典).

    The film is 100% American. However, if you've ever felt that anybody could do a better job running the country than the people in power, then you'll enjoy Dave!

    For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).

    Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安装) a large number of internet-connected features in machines in an effort to make them “smart”.

    Last year, it was a refrigerator that tweeted. This year, it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.

    The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners are at work or on the bus.

    Samsung says it's not just something new — the app connection actually has some practical uses.

     “If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.

    The company also says that with electricity rate(电价)varying depending on the time of day, more control over when the machines are used can help save money.

    Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.

    It's common for children to grow up being told to minimize daydreaming, and instead to focus on lessons and class work. Historically, daydreaming students who go off on their own thoughts, rather than focusing on the teachers, the blackboard, or their class work, are often encouraged to stop allowing their attention to wander and to bring themselves back into the present moment. They're described as uninterested in school work and their future. Traditionally, daydreaming is seen as a practice that results in bad consequences.

    But recent studies are beginning to renounce those common beliefs by pointing out the potential benefits that daydreaming may provide. PsychCentral reports that Mary Smith, a psychological scientist and researcher, recently examined scientific writings and studies to gain a better understanding of the role of a reflective brain. These studies have shown that the brain has a network that is active when a person is daydreaming and that brain network can help memory and learning.

    Though paying attention in school is important, these results suggest that there should be time for students to daydream, too. Giving them the chance to reflect and daydream can help improve learning and development. Research also indicates that when students are permitted to daydream, they experience less anxiety and become more motivated. On the other hand, if students are warned against daydreaming, their knowledge of themselves and the world around them may suffer.

    As a result, educators are encouraged to promote a balance between outward and inward attention. A little bit of daydreaming to break up the hard focus on school activities can be beneficial, and it may help students become better, active learners.

    As for students, the lesson here is not to be afraid of doing some daydreaming. Sure, you want to pay attention to the vital information conveyed to you during your classes, but don't get discouraged if your mind wanders. A little bit of daydreaming is healthy.

    Justin Bieber is only fifteen years old and has become very popular already. He was raised (抚养) by his mother in Stratford, Ontario, Canada. When he was twelve he won second place in a local singing contest. He started posting (贴) videos of his contest performances on the Internet for his friends and family. Soon these videos had been seen more than ten million times.

    A music manager saw those videos and asked Justin to fly to Atlanta, Georgia, to meet the singer and songwriter Usher. A year later Justin released (发行) his first albumMy World. It sold over a million copies in the first two months. Four singles were released before the album. All became popular. This made Justin Bieber the only singer in the history of the Billboard magazine to have four singles from his first album among the most popular songs before the album's release.

    Justin Bieber performed for President Obama at the White House last December. He was part of a musical show that raised money for the National Children's Medical Center. He was also among the many singers who recorded the song We Are the World. The song was produced to raise money for Haiti. The video has been seen more than seven million times on the Internet. And it was shown during the opening ceremony of the 2010 Winter Olympics in Vancouver.

    Justin Bieber's family did not have much money when he was young. He did not have as much so other children did. Justin says he wants to influence young people in a good way. He believes that you can do anything if you put your mind to it.

Every profession or trade, every art, and every science has its technical vocabulary, the function of which is partly to name things, or processes which have no names in ordinary English, and partly to secure greater exactness in terminology (术语). Such special dialects are necessary in technical discussion of any kind. Being universally understood by those engaged or interested in the particular science or art, they have the accurateness of a mathematical formula (公式）. Besides，they save time in these kinds of discussions, for it is much more economical to name a process than to describe it. Thousands of these technical terms are very properly included in every large dictionary, yet, as a whole, they are rather in the suburbs of the English language.

Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other professions, like farming and fishery, which have occupied great numbers of men from remote times, the technical vocabulary is very old. It consists largely of native words, or of borrowed words that have worked themselves into the very central part of our language. Thus, though highly technical in many particulars, these vocabularies are more familiar in sound, and more generally understood, than most other technical terms. In law, medicine, and philosophy, the special dialects have also become pretty familiar to cultivated persons and have contributed much to the popular vocabulary. Yet among these professions, each one still possesses a large body of technical terms that remain essentially foreign, even to educated speech. And the proportion has increased in the last fifty years, particularly in the various departments of natural and political science and in the mechanic arts. Here new terms are coined with the greatest freedom, and abandoned when they have served their turn. Most of the newly-invented terms are restricted to special discussions, and seldom get into general literature or conversation.

Yet no profession is nowadays, as all professions once were, a close combination. Lawyers, doctors and men of science all communicate freely with others, not in a merely professional way. Furthermore, what is called "popular science" makes everybody familiar with modem views and recent discoveries. Any important experiment, though made in a remote or provincial laboratory, is at once reported online, and everybody is soon talking about it-as in the case of AI.
