A chip inserted in a young quadriplegic's (四肢麻痹患者) brain is already improving his quality of life. Soon the benefits may be more widespread.

    A 25-year-old man unable to move from the neck down recently did what many assumed impossible. After a knife attack that had left him paralyzed, all he could move was his head, which he used to push a switch and call for a nurse. And he could turn his wheelchair by blowing into a straw near his face. That was it.

    Then last June, a Foxborough (Mass.) company called Cyber Kinetics opened the man's skull and inserted a special chip no larger than a baby aspirin. That insert has given him a few additional and precious abilities. When connected to a special computer via a cable, the chip translates the young man's thoughts into commands that let him move a cursor across a PC screen and open e-mail. He can draw a circle with a computer painting program. And he can use a robotic hook(钩) to perform simple tasks like picking up a candy and sliding it across a table.

    All he has to do is to think.

    Several new studies have begun or been completed in the past year. In fact, more than half of the scientific papers in this field, called brain-to-computer interaction (BCI), have been published in the past two years, notes Jonathan Wolpaw, a research physician at Wadsworth Center, the New York State Health Dept.'s research laboratory.

    Brain surgeries (手术) are no longer rare: Thousands of Parkinson's disease patients have had special devices inserted in their brains to ease uncontrollable shaking and other symptoms. The inserts themselves have improved, so the body doesn't reject them as furiously(猛烈地). And significant development has been achieved in software used to interpret the brain's signals and change them into commands understood by computers.

    But increased demand for thought technology remains the biggest reason for the field's progress. Today, 4 million Americans live with paralysis according to the Christopher Reeve Paralysis Foundation.

    Scientists hope that thought technology will reduce the impact of such disabilities. People with spinal-cord injuries, for example, often lose their ability to walk because the communications network between their brain and their legs has been interrupted. The brain still commands the leg muscles to move, but they don't hear its orders.

    Thought technology, scientists hope, will bridge this communications gap. "Our goal is for you to see paralyzed people eating at a restaurant and for you not to know that they are paralyzed," says John Donoghue, founder and chief scientific officer at Cyber Kinetics.

    Proper diet and regular exercise seem to be the only methods for losing weight.However,the importance of water should be added in the process.While medical science has proven the positive effects of water,most people still do not drink enough each day.

    The reason why water is so important for weight loss has something to do with metabolism（新陈代谢）of fat. The liver（肝脏）is in charge of this process when it comes to turning stored fat in-to energy.However,the liver is also responsible for helping the kidneys（肾脏）that need enough water in order to function properly.The liver has to perform all the functions of the kidneys on its own when they are short of water.This means the liver doesn't have enough energy to metabolize fat.So,drinking water allows the kidneys to focus on their job and the liver to focus on its job.

    Also,studies have shown that water can make us feel full when drunk before meals.Without even making an effort,most people who drink a glass of water before a meal will eat 33% less.This is due in part to the fact that they simply get fuller quicker because the water is taking up space.The other reason is that the food will expand as soon as it hits the water-filled stomach.

    Water is important for every aspect of the health of the human body.By drinking more water and improving the health of the body,weight loss goals can be achieved with greater ease.

    Hobbs was an orphan(孤儿). He worked in a factory and every day he got a little money. Hard work changed him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts.

   One day the lawyer said to him, "One thousand dollars, and here is the money." As Hobbs took the package of notes, he was very dumbfounded (惊呆的). He didn't know where the money came from and how to spend it. He said to himself, "I could go to find a hotel and live like a rich man for a few days; or I give up my work in the factory and do what I'd like to do: painting pictures I could do that for a few weeks, but what would I do after that? I should have lost my place of the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting pictures. But it's too much for one and too little for the other."

    "Here is the reading of your uncle's will," said the lawyer, "telling what is to be done with this money after his death. I must ask you to remember one point. Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it."

    "Yes, I see. I'll do that." said the young man.

    Fantasy as a genre is often unfairly wronged. While there are plenty of authors who seem to be paid by the word and are only concerned with expanding volume, there are many authors producing fantastic works that are worthy of the word literature. While there were many worthy competitors, here are what we consider to be the great work of the greatest fantasy series of all time.

    ①The Dark Tower by Stephen King

    The Dark Tower actually shares some similarities with The Wheel of Time. In both series the first four books are the strongest, and you also get the sense with both Robert Jordan and Stephen King that they didn't quite know how to end their creation, which led to a very controversial ending in The Dark Tower's case along with some questionable decisions by King like his self-insertion in the story.

    King has created one of the most iconic fantasy characters of all time in the Gunslinger Roland and the world he creates, with all of its similarities to our reality, is a prosperous one. It's too bad that Stephen King doesn't dabble(涉猎) more in fantasy, because he clearly has a talent for world building. Not to mention everything he writes seems to be phone book sized, which would fit right in with the fantasy genre.

    ②Harry Potter by J.K. Rowling

    When considering a ranking of the greatest fantasy series of all time, the question of Harry Potter is a tricky one. There's inevitably opposition when something is as popular as Rowling's work, and add to that the fact that the series is seemingly meant for children and you have a case that naturally inspires a lot of debate. I'm not sure I believe Rowling did anything particularly new with Harry Potter, but a work doesn't necessarily have to be innovative for it to be great. Nearly every fantasy series owes a debt to Tolkien for instance, but that doesn't mean Tolkien has written the only work of fantasy that matters. Rowling didn't really come up with anything new, but the connection she made with tens of millions of readers is praiseworthy. People will be reading Harry Potter for decades to come, and I'm not sure a better introduction to fantasy could be found.

    Universities and colleges in the United States are trying new programs for international students to increase enrollment and income. Some universities are experimenting with bringing international high school students to their campuses. These programs permit students to complete their high school diploma while earning college credit at the same time.

    One example of this model is at the University of Southern Maine, or USM. The program is called the "International Academy". The school is expecting its first class of international high school students this fall. Joanna Evans is the director for the academy. The program is officially a "boarding school on a university campus" that serves 11th and 12th grade international high school students only.

    The students will take classes at the University of Southern Maine to complete their high school diploma. However, because the classes are university-level, the students will receive college credit at the same time.

    According to Evans, the students they admit will have to be very strong. Their course schedule will be the same as taking only advanced-placement courses. The goal is that, by the time they complete their high school diploma at the academy, they will be ready to start college as a third-year college student.

    Their English language skills also must be strong. The Academy looks for students with a minimum Test of English as a Foreign Language, or TOEFL score of 79,or a 6.5 on the International English Testing System, or EELTS. However, there are classes available to provide additional English language training when the students arrive if they need it.

    All incoming students at the academy are required to take a college writing class in their first term. If English is not their first language, they will take a class taught by teachers with a background in teaching students who speak English as a foreign language.

    Although they are only high school students, the expectations are the same as college students. "Students need to be ready to take university classes, and that is the deal" Evans said.

    If you rent an apartment in Beijing, you also rent the landlord or landlady for at least a year. It's important you find a good match because you have to deal with them in the long term. For me, it was love at first sight with the elderly couple who owns my apartment.

    It was quite a tough trying to find the right apartment when I first arrived in Beijing. The apartments were either unsuitable or I find fault with the owners who looked indifferent at best and unfriendly at worst. But that all changed when the renting agent's car stopped in front of a hutong house in the heart of the capital.

    I saw an elderly couple, in their 70s perhaps, waving to me. They were warm and welcoming at first glance, and when I saw them attentively hanging up the curtains in what would become my bedroom, I was just about sold on the place and the owners!

    Chinese people talk about yuanfen, meaning fate that brings people together. Before I met my current landlords, I thought the concept of yuanfen was overrated. A generous landlady who liked me and wanted me to move into her apartment had used the term in reference to me. But it was this lovely couple that changed my mind about the concept.

    We have become accustomed to visiting each other at home. The couple's apartment is lovingly decorated, boasting a recent wedding photo of themselves taken in bridal wear. The landlord likes to smoke and sip tea, while the landlady takes great pride in her appearance.

    After three years, I dare say they treat me a bit like a "daughter", despite having two grown sons, one of them close by. They give me gifts of tea or clothes, and I bring them souvenirs from my trips. A match made in heaven, indeed!
