阅读理解     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. （1） What does the underlined phrase “tech neck” in Paragraph 2 refer to? A . The painful neck caused by electronic devices. B . The strong neck after technical physical exercises. C . The decoration on the neck with hand-held devices. D . The cell phone or iPad frequently hung on the neck. （2） What can we learn from Kimberly Fielding's findings? A . Muscle tension can lead to spine curving and headaches. B . Nerve pain and other problems are caused by disc herniation. C . Staring down at your smartphone does great harm to your neck spine. D . Quality of life depends in a large part on the condition of neck spine. （3） Why did Kimberly Fielding start the class? A . To introduce her newly-invented devices. B . To help those suffering from tech neck. C . To further study the causes of tech neck. D . To stress the danger of hand-held devices. （4） What is the purpose of the last paragraph? A .
