    Dictionaries are not closed books. There is still plenty of room for more words in these great vocabulary authorities. New words are continually being created and added to our language. And many of today's word experts can credit a famous mathematician with the creation of the method by which they develop many new words. The mathematician was an Englishman named Charles L. Dodgson. In addition to working with figures, Dodgson wrote books. His imaginative stories and poems have made Dodgson beloved to generations of readers. We know him, however, not by the name of Dodgson but by his pen name, Lewis Carroll.

    Lewis Carroll has delighted countless readers, young and old, with Alice in Wonderland, Through the Looking Glass, and numerous poems. In these works, Carroll developed dozens of nonsensical words such as "chortle" and "galumph". Many of these words are combined naturally with more common words in the English language. Carroll referred to his made-up words as "portmanteau" words, named after a kind of leather suitcase that opens into two compartments. The name was well suited, because most of Carroll's words had two compartments. Rather than being entirely fabricated（虚构）, they were usually made from the combined parts of two different words. A "snark", for example, clearly came from a snake and a shark.

    Although Carroll died long ago, his technique continues to be used today. We clearly see his influence in such words as smog, brunch, and guesstimate.

    Many kids don't drink enough water daily, according to a new study. The study's lead author, Erica Kenney, at first planned to look into the amount of sugary drinks kids were drinking in schools. However, during her research she found that many kids were simply not drinking enough water.

    Kenney and her team examined data from a group of 4,000 children, aged 6 to19. The data was taken from the National Health and Nutrition Survey, a study on the health of children in the United States done each year by the Center for Disease Control and Prevention.

    While looking through the survey results, she noticed that more than half of the kids who took part in the study were dehydrated (脱水的). Of that group, boys were 76% more likely than girls not to have enough water in their system. Nearly one quarter of the kids in the survey reported drinking no plain water at all.

    “These findings highlight (突出) a possible health issue that wasn't given a lot of attention in the past,” Kenney said in a statement. “Even though for most of these kids this is not an immediate and great health risk, this is an issue that could really be reducing quality of life and well-being for many children and youth.”

    The United States-National Agriculture Library says average kids need between 10 to 14 cups of water every day. This water can come from a mix of drinks and foods that contain high amounts of water, such as celery, melons or tomatoes. It is also suggested that fluids (液体) come from water instead of sugary drinks that are high in calories and can lead to weight problems.

    I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St, Lucie just minutes from the ocean, an un-controllable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida's mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.

    I'm like a migratory bird (候鸟) that has lost its sense of timing and direction, my wings flapping against season.

    So what makes me fly against the tide of snowbirds? The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display of colors-first in the fall trees, and then in the lights around homes and at Rockefeller Center. Floridians decorate too, but can't create the special feel of a New England winter.

    I suppose the biggest reason why I return is to celebrate the holidays with people I haven't seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors children excitedly open gifts on Christmas? Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch. (My wife and I spend winters at a retirement community in Ridge, and I'm grateful that I don't have to shovel.)

    While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can't go home?

    It is becoming increasingly important for researchers to closely monitor our ocean life. However, observing sea creatures up close is almost impossible since human presence scares them. Now, thanks to The Soft Robotic Fish, also known as SoFi, researchers may be able to keep a close eye on the sea creatures.

    Built by MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), the white re- mote-controlled robot resembles the real fish, complete with a tail that waves from side to side. Though not the first autonomous underwater vehicle (AUV) created to monitor the ocean, SoFi settles many of the problems that have blocked the usefulness of the previous robot fish.

    Previous AUVs have had to be linked to boats because radio frequency communications don't work well underwater. To overcome the problem, Director of the CSALL Daniela Rus and her team used sound waves. The technology can travel greater distances allowing divers to pilot SoFi from up to 50 feet away.

    Also limiting the usefulness of traditional AUVs is the risk of collision. With the outside made of soft silicone (硅树脂) rubber and flexible plastic that keeps its inbuilt electronics dry, SoFi poses no such danger. "Collision avoidance often leads to unnecessary movement, since the robot has to settle for a collision-free path", says Rus. "In contrast, a SoFi robot is not only more likely to survive a collision but also could use it as information to form a more workable movement plan next time around."

    During test dives, SoFi moved alongside the ocean life at depths of 50 feet for up to 40 minutes at a time, taking photos and making videos. The researchers say sometimes the fish would swim a- longside the strange-looking robot-fish out of curiosity, while at other times they took no notice of its existence.

    While SoFi presently only records video, future versions will include sensors. The researchers also hope to make it more autonomous. "We imagine someday it might help us uncover more secrets from the amazing underwater world that we know so little about," says Rus.
