    People often ask which is the most difficult language to learn, and it is not easy to answer because there are many factors to take into consideration. Firstly, in a first language the differences are unimportant as people learn their mother tongue naturally, so the question of how hard a language is to learn is only relevant when learning a second language.

    A native speaker of Spanish, for example, will find Portuguese much easier to learn than a native speaker of Chinese, for example, because Portuguese is very similar to Spanish, while Chinese is very different, so first language can affect learning a second language. The greater the differences between the second language and our first, the harder it will be for most people to learn.

    Many people answer that Chinese is the hardest language to learn, possibly influenced by the thought of learning the Chinese writing system, and the pronunciation of Chinese does appear to be very difficult for many foreign learners. However, for Japanese speakers, who already use Chinese characters in their own language, learning writing will be less difficult than for speakers of languages using the Roman alphabet.

    Different cultures and individuals will find different languages more difficult. In the case of Hungarian for British learners, it is not a question of the writing system, which uses a similar alphabet, but the grammatical complexity, though native speakers may find it easier, struggling with languages that the British find relatively hard.

    No language is easy to learn well, though languages which are related to our first language are easier. Learning a completely different writing system is a huge challenge, but that does not necessarily make a language more difficult than another. In the end, it is impossible to say that one language that is the most difficult language in the world.

    Most of us will be familiar with the traditional talent show set-up: thousands of hopefuls line up outside the audition（试音）room, wait for hours to go in and perform for a group of judges. Then these potential pop stars could be lucky and get through to the next round, or they might hear the command, "Sorry, it's a no from me. But what do the judges actually bring to a talent show?

    Music talent show judges attract millions of viewers each week to their programs. As public figures, they play an important part in advertising campaigns for these programs. They often receive high salaries and can be moody. Are they really worth the expenses and difficulties that they cause? One solution might be to replace them with computers.

    Can computers really match human judges? Scientist Dr Nick Collins and his team at the University of Sussex think they can. Dr Collins has been working on a project that involves programming three computerized judges that he says would be far more consistent in their judgment of musical performances. Employing a special programming language, Dr Collins's digital judges can be trained up by "listening" to particular musical styles. After they have been listening for a while, the programming language allows these judges to spot the specific features of the music, including the voice quality, the rhythm etc. Collins says, “The judges' listening capacity is not yet as good as a human ear, but they won't be as moody as some human reality TV show judges.”

    Maybe that is the problem with this electronic musical innovation. Real human judges on talent shows interest us with their personality, decisions and catchy phrases. Will a computer program be able to do the same?

    Poet William Stafford once said that we are defined more by the detours(绕行路) in life than by the narrow road toward goals. I like this image. But it was quite by accident that I discovered the deep meaning of his words.

    For years we made the long drive from our home in Seattle to my parents' home in Boise in nine hours. We traveled the way most people do: the fastest, shortest, easiest road, especially when I was alone with four noisy, restless kids who hate confinement(限制) and have strong opinions about everything.

    Road trips felt risky, so I would drive fast, stopping only when I had to. We would stick to the freeways and arrive tired.

    But then Banner, our lamb was born. He was rejected by his mama days before our planned trip to Boise. I had two choices: leave Banner with my husband, or take him with me. My husband made the decision for me.

    That is how I found myself on the road with four kids, a baby lamb and nothing but my everlasting optimism to see me through. We took the country roads out of necessity. We had to stop every hour, let Banner shake out his legs and feed him. The kids chased him and one another. They'd get back in the car breathless and energized, smelling fresh from the cold air.

    We explored side roads, catching grasshopper in waist-high grass. Even if we simply looked out of the car window, at baby pigs following their mother, or fish leaping out of the water, it was better than the best ride down the freeway. Here was life. And new horizons(见识).

    We eventually arrived at my parents' doorstep astonishingly fresh and full of stories.

    I grew brave with the trip back home and creative with my disciplining technique.

    On an empty section of road, everyone started quarreling. I stopped the car, ordered all kids out and told them to meet me up ahead. I parked my car half a mile away and read my book in sweet silence.

    Some road trips are by necessity fast and straight. But that trip with Banner opened our eyes to a world available to anyone adventurous enough to wander around and made me realize that a detour may uncover the best part of a journey-and the best part of yourself.
