Every year in America, high-school students who want to go to college take a national examination called the Scholastic Aptitude Test, or SAT in a shortened way. Their score is an important factor in determining which colleges will admit them or whether any will be admitted at all. The Scholastic Aptitude Test measures one's mathematical ability and use of the English language. Traditionally, the English part involved grammatical questions and paragraphs that test reading comprehension.

    But the SAT folks have added a single question, to be answered in an essay, hand-written on the spot. That's an interesting way to test writing ability, but content aside, have you ever seen young people's handwriting lately? Or anyone's for that matter, in this age of computer keyboards? Students write numbers and sign their names on bank checks. They scribble class notes in what can generously be described as the written word.

    Yet today's kids are asked to write, thoughtfully and clearly, for several minutes on this SAT Test. Good luck to the text scorers who must work out difficultly the scrawl (潦草的字迹) of young people who've been typing on computers since the age of three! Teachers insist that good handwriting can not only help one's score on the SAT, but also, later on in life, impress potential employers. And don't forget, we all have to turn to handwriting from time to time, as computers go down when power goes out.

    Then how to improve the handwriting? Well, with a few simple steps you can improve your hand writing.

    Position the pen. You should hold the pen between the forefinger and the thumb, then rest it near the first knuckle (指节) of the middle finger. The rest of your fingers should be curled (卷曲) under your hand and your hand should remain relaxed.

    Evaluate your writing. Make changes to your letters till you like how they look.

    Take your time. Speed is bound to make your writing messy-looking.

    Practice. Practice it a lot; it's not enough to do it once and hope for the best. It has to be something you work at to make great improvements.

    Planning a visit to the UK? Here we help with ways to cut your costs.

    AVOID BIG EVENTS  Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival (19 Oct.) cost £169.15 at Booking.com. A week later, the same room cost £118.15.

    If you can be flexible and want to know dates to avoid—or you're looking for a big event to pass your time—check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category.

    STAYAWAY FROM THE STATION If traveling to your destination by train, you may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday.

    Don't be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge's Central Euston hotel in London for Saturday 22 September was £95.95. A room just a tube journey away at its Covent Garden hotel was £75.75. And at Farringdon, a double room cost just £62.95.

    LOOK AFTER YOURSELF Really central hotels in cities such as London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. As an alternative consider checking into a self-catering flat with its own kitchen. Often these flats are hidden away on the top floors of city centre buildings. A great example is the historic O'Neill Flat on Edinburgh's Royal Mile, available for £420 for five days in late September, with room for four adults.

    GET ON A BIKE London's ‘Boris bikes' have attracted the most attention, but other cities also have similar programmes that let you rent a bicycle and explore at your own pace, saving you on public transport or car parking costs.

    Among the smaller cities with their own programmes are Newcastle (casual members pay around £1.50 for two hours) and Cardiff (free for up to 30 minutes, or £5 per day).  (358 words)

    Dodder is an unusual and unwanted plant that attacks other plants. Except for its flowers, the plant looks like spaghetti, a kind of noodles in the shape of long thin pieces that look like string when they are cooked. It's almost leafless, thread-like stems hang down on top of other plants that dodder needs to stay alive. Dodder does not produce its own food. Instead, it steals food from other plants. It feeds by sucking juices from the plant which is wrapped around, often making its host very weak or even killing it.

    Dodder can find other plants by their smell. When a young dodder plant starts growing, it follows the smell of plants it prefers, like tomato plants, potato plants, or other farm crops. Unlike most plants that usually grow in the direction of light or warmth, a dodder plant will grow in the direction of, for example, tomato smell—if a tomato happens to be growing nearby.

    However, a young dodder plant must find a host plant quickly. It no longer needs its root once it is attached to the host and wrapped around it. If it cannot catch a smell of a potential host within a few days, it will dry up and vanish even if there is plenty of water around. Once it finds a host, the young dodder plant will attach itself to it and start growing faster. At that point the dodder plant will drop its root.

    Dodder is thus a difficult weed to manage and a real headache for farmers. When it does get out of hand, dodder can greatly reduce a farmer's harvest or even destroy crops completely. Before sowing their produce, especially farmers in warm parts of the world often check to make sure no unwanted dodder seeds have mixed with their crop seeds. This is a good way to stop dodder plants from making their way to a crop field secretly.

    Do you think horseback riding is easy? Well, you are wrong. Horseback riding is one of the most challenging sports in the world today.

    As you know, a horse has the instinct to run away when afraid. When he becomes puzzled, he becomes afraid. When your silent communication is confusing, he does not ask you to repeat what you have said. Instead, he runs forward, he jumps to the side, he kicks out, or he freezes in place. Most of the time, however, you won't know your communication is confusing until it is too late. When he runs forward, you will fall back. When he jumps to side, you will fall the other way. When he kicks out or freezes in place, you will fly over his head.

    If you want to be good at horseback riding, you must practice. Being ridden does not come naturally to horses. They have to be trained. For example, to ask them to go forward, you usually tap them with your heels. But, if you get on untrained horses, they won't know that a tap means go. Instead, they will most likely run around like a wild animal out of fear.

    Contrary to popular belief, horseback riding does take skill. If you believe horseback riding doesn't take skill, you most likely have only ridden at a farm that provides a well-trained horse. To me, that is not actual riding. And although it may seem easy to you, you were not the person to teach that horse that a saddle is not frightening. You were not the person to fall off that same horse at the beginning of his training. When horses are first taught to be ridden, all they do is run, kick out, and rear, which is the act of standing on their back legs only.

    Dogs are our best friends. That's especially true after a disaster, such as an earthquake. When buildings fall down, search and rescue dogs help find trapped people. Dogs' amazing noses can pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. It's taking smell detection(探测) to a whole new level.

    The new invention is a sort of electronic nose, which can detect extremely low levels of many compounds(化合物) from people's skin. This isn't the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and small enough to fit inside hand-held equipment.

    The electronic nose can detect extremely slight smell of more than one compound at the same time. "Being able to do this, in such a small object, is the significant discovery," says Sotiris E. Pratsinis, Professor of Process Engineering&Materials Science at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels.

The results were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. "Ideally, this technology could replace search and rescue dogs," Pratsinis says.

    Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, "I foresee that such an object could add to the fine work done by the dogs." Taylor also pointed out some potential limitations of the new invention. "E-noses are useful, but can be very likely to be affected by unstable readings and interruption," he says.
