    For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).

    Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安装) a large number of internet-connected features in machines in an effort to make them “smart”.

    Last year, it was a refrigerator that tweeted. This year, it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.

    The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners are at work or on the bus.

    Samsung says it's not just something new — the app connection actually has some practical uses.

     “If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.

    The company also says that with electricity rate(电价)varying depending on the time of day, more control over when the machines are used can help save money.

    Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.

    American schools do not have separate classes for boys and girls. If boys want to cook or to sew, they can learn these things in classes that are no longer just for girls. If girls want to repair cars, they can now learn this in school. Most students like to have boys and girls on the same baseball team.

    Many boys and girls dress alike in school. They wear blue jeans and sport shirts. Some have long hair and some have short hair. Sometimes a boy has longer hair than a girl.

    Even the language is different. Students learn to say fire fighter instead of fireman, police officer instead of policeman, and letter carrier instead of mailman. A person does not need to be a man to fight a fire or to deliver the mail.

    Most people think that these changes are great. They give all people an equal chance to be happy and to do what they want to do with their lives. Fathers like to tell their sons that they can grow up to be president. Today, mothers can tell the same things to their daughters.

    Can you remember the day when you spoke your first word? If you can, you are unusual. Try to imagine what first few months of your life were like. I am sure you just spent most of your time eating, sleeping and crying. As you grew older, you were awake more of the time. It took your parents more time to play with you and talk to you. You watched and listened curiously (好奇). You began to know that people made certain sounds to go with certain things.

    Then you began to try making the sounds you heard. And step by step you were able to make the right sound for one thing. On that day you came to understand the secret of language. The secret is that a certain sound means a certain thing. One sound might be as good as another. But it is no good as a word unless everybody agrees on its meaning. Only when a group of people use the same set of sounds of things, can they understand each other. Then, and only then do these people have a LANGUAGE.

    After you found the secret of language, you learned words. Some of the words meant things, such as BOOKS, CHAIRS and SHOES. Some words meant doing things, such as GO and SWIM, and other words describe things, such as GOOD and DIRTY. Soon you learned to put words together to express your idea, such as “I want to go out and play with my friends.” This is language. By means of language people can communicate. So we say languages are means of communication.

    When we do the same movements with our bodies over and over again, we overuse some muscles. And that overuse can lead to strain(紧张)and injury. Sometimes those problems can come from doing sports. But exercise experts say they are now seeing another cause for muscle problems: hand-held technology devices(设备).

    Staring down at your phone or tablet for long periods of time puts great tension on your neck and spine(脊椎). Many people who use tech devices also bend their shoulders forward. Experts say this posture(姿势)puts strain on the entire upper body. Muscle strain linked to hand-held technology has become such a common condition that it now has a name: tech neck.

    Kimberly Fielding, an exercise teacher in New York City, explains that constantly looking down at our devices creates an unnatural bend in our spine. This can cause nerve pain and other problems. “A lot of the curves of the neck can change, so instead of the neck spine going inward, the curve can be a little bit different and it causes nerve pain and disc herniation(椎间盘突出)and different muscle tension headaches — different things that really can reduce quality of life.”

    Fielding created a class to directly solve the problem of tech neck. The class uses different exercises to release tension in the upper body and strengthen back and neck muscles. Fielding says these exercises may feel uncomfortable in the beginning because the neck muscles may have become weak.

    However, you don't need to take a class like Fielding's. You can take simple steps to improve tech neck. For a quick fix, hold your phone at eye level. At the same time, take breaks from using your technology by standing up and stretching your legs often. Also, give your eyes a break by closing them throughout the day.
