Your smartphone(智能手机) can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little device（设备）of yours – it might also spread disease.

    “People are just as likely to get sick from their phones as from handles of the bathroom,” Jeffrey Cain, the president of the American Academy of Family Physicians, told The Wall Street Journal.

    This may be hard to believe, but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms(大肠菌), a kind of bacteria found in excrement(粪便)，with about 2,700 to 4,200 units of the bacteria on each phone. In drinking water, the healthy limit is less than 1 unit per 100 ml of water. This bacteria can cause flu, pinkeye（红眼病）and diarrhea(腹泻).

    Although computers, keys and pens all carry germs(细菌), our smartphones get far dirtier. They touch a lot of stuff, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn't played Angry Birds of Fruit Ninja while sitting on the toilet?

    “Some things that we think are personal are actually more public than we imagine,” Cain said.

    What's even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don't think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease（油脂）, an environment that germs really like.

    Compared to traditional keypads（键盘）, touch screens transmit（传播）germs more easily to hands. According to Time magazine's website, an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.

    So how do you keep your smartphone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone's surface: wash your hands regularly.

Pride and Prejudice for the Modern Woman

    Let us imagine how Pride and Prejudice, Jane Austen's most famous work, might be updated, 200 years on.

    Austen's popularity is rooted in her intelligence. But today she would certainly have had a very different life, as would her characters. Here's my own suggestion.

    It is a truth finally and universally acknowledged that a single woman with brains deserves to have equal opportunities to men, however disadvantaged she may feel by sexism.

    " My dear husband," said his hopeful wife one day, " have you heard that the local store, standing empty for so long, is taken over by a bright young businesswoman?"

    Her dull and indifferent (漠不关心的) husband replied that he had not. "But it is, it is," she replied excitedly. Mr Dull-Husband made no reply.

    "Don't you want to know her plans?" she cried with some impatience.

    "Well, clearly you think it matters to your silly little head. .. so I'd better listen. "

    "Well, my dear, the rumour (传言) is that she has already set up a string of successful businesses in northern England, though how a woman can know anything about that is beyond me. She will move in herself next month. " "What is her name?" "Bingley. "

    "Is she married or single?"

    "What a question! And none of your business. But her coming will be a fine thing for our five boys. " "How so? How can it possibly affect them? "

    "My dear love; those lazy boys need something to wake them up. There are bound to be jobs going. "

    " Is that her point in settling here? Surely as a woman she has simply taken a fancy to the place. "

    " Nonsense, my love, how little you've noticed the world has changed. She's got a first-rate degree and some sort of business qualification, I'm told. She surely needs one of our boys! Perhaps you might give her a call. "

    " Me? No. Perhaps you can take an interest. You still have your looks, after all. She may even offer you a job. " "Oh, that's not likely. These new chances belong to the younger generation. But now you mention it, I think I'll go along all the same. "

    And Mrs Bennet went along. That was 10 years ago. She is now managing director of a FTSE-listed company.

     It would remain the case, of course, that Mrs Bennet would be one of very few women on the company board, that her salary would be lower than her male colleagues, her bonus of a more "female" dimension and her lifespan (年限) among the city's business leaders shorter than theirs. Still, she'd no doubt have enjoyed Davos—and might even have hobnobbed (攀谈) with influential figures.

    Which tablet computer should YOU be buying: They are this year's must have ... and there's a style to suit everyone.

    We've all heard the saying: practice makes prefect! In other words, acquiring skills takes time and effort. But how exactly does one go about learning a complex subject such as tennis, calculus, or even how to play the violin? An age-old answer is: practice one skill at a time. A beginning pianist might rehearse scales(音阶) before chords(和弦). A young tennis player practices the forehand before the backhand. Learning researchers call this “blocking”， and because it is common and easy to schedule, blocking is dominant in schools, training programs, and other settings.

    However another strategy promises improved results. Enter “interleaving”， a largely unheard-of technique that is catching the attention of  cognitive(认知) psychologists and neuroscientists. Blocking involves practicing one skill at a time before the next (for example, “skill A” before “skill B” and so on, forming the pattern “AAABBBCCC”), while in interleaving one mixes practice on several related skills together (forming for example the pattern “ABCABCABC”).

    Over the past four decades, a small but growing body of research has found that interleaving often outperforms blocking for a variety of subjects, including sports and category learning. Yet there have been almost no studies of the technique in unplanned, real world settings-until recently. New research in schools finds that interleaving produces dramatic and long-lasting benefits for an essential skill: math. Not only does this finding have the potential to transform how math is taught, it may also change how people learn more generally.

    Researches are now working to understand why interleaving produces such impressive results. One important explanation is that it improves the brain's ability to tell apart between concepts. With blocking, once you know what solution to use, or movement to do, the hard part is over. With interleaving, each practice attempt is different from the last, so rote(死记硬背) responses don't work. Instead, your brain must continuously focus on searching for different solutions. That process can improve your ability to learn critical features of skills and concepts, which then better enables you to select and produce the correct response.

    A second explanation is that interleaving strengthens memory associations. With blocking, a single strategy，temporarily held in short-term memory, is sufficient. That's not the case with interleaving-the correct solution changes from one practice attempt to the next. As a result, your brain is continually engaged at regaining different responses and bringing them into short-term memory. Repeating that process can strengthen neural connections between different tasks and correct responses, which improves learning.

    Both of these accounts imply that increased effort during training, either to discriminate correct responses or to strengthen them, is needed when interleaving is used. This corresponds to a potential drawback of the technique, namely that the learning process often feels more gradual and difficult in the beginning. However, that added effort can have better, longer-lasting results.

    Mr. Bean is an internationally recognized comedy character on TV and in films. He constantly gets into awkward and absurd situations, which greatly amuses audiences regardless of their nationalities or culture. The humour is always made clear through a series of simple and funny acts that rely purely on body language, which is universal.

    One of my favourite shows is that Mr. Bean has a meal in a fancy restaurant. After being seated at his table, Mr. Bean takes out a card, writes a few words on it, seals (密封) it in an envelope and places it on the table. After a moment, he looks back at the envelope but this time he looks surprised, as if he did not know it was there. He opens it to find a birthday card and delightedly puts it on the table for everyone to see.

    When he looks at the menu, an astonished look swiftly appears on his face. He takes all the money out of his wallet, counts it and puts it in a saucer (茶托). He then looks from the menu to the money with concern until he finds one thing that makes him smile. Then he orders a dish called "steak tartare". When the dish arrives, he is shocked to discover that "steak tartare" is actually raw hamburger. He makes an attempt to eat it, but it is clear from the look on his face that he finds the taste truly disgusting. He cannot hide his feelings, except when the waiter asks if everything is all right. When this happens, he smiles and nods, indicating that everything is fine. When the waiter is not looking, however, he busies himself hiding the raw meat anywhere he can reach-the sugar bowl, the tiny flower vase, inside a bun (小圆面包) and under a plate. He becomes so desperate in the end that he even hides some inside the purse of a woman sitting near him and throws some down the trousers of the restaurant's violinist!

    I like to watch Mr. Bean on TV, but I wouldn't like to meet someone like him in real life and I certainly wouldn't like to have dinner with him!
