【题目】

“Text Neck is not just a texting problem,” said Dr. Dean Fishman. “Text Neck is a gaming problem. Text Neck is an e-mailing problem.”

Fishman made up the term “Text Neck” in 2008 while examining a 17-year-old patient. The teen came in complaining of neck pain. Fishman noticed that the teen was sitting in a chair, bending (弯曲) over her smartphone, texting away. “I knew I had something,” Fishman said.

A recent study published in Surgical Technology International’s 25th edition says texting may be hurting your back. The study found that bending your head to look at your mobile phone held in your hands can put up to 60 pounds of pressure (压力) on your neck. The average human head weighs 10 pounds in a right position – when your ears are over your shoulders. For every inch you bend your head forward, the pressure on your back doubles.

Staying in the “forward head posture” can lead to many problems. Over time, it can even change the natural curve (曲线) of your neck.

Dr. Michelle Collie, director of Performance Physical Therapy in Rhode Island, recently says Text Neck has increased very quickly, especially among her younger patients. According to the Kaiser Family Foundation, 8- to 18-year-olds spend almost seven and a half hours using mobile device or desktop computer for fun every day.

So what’s a smartphone-texting, laptop-loving guy to do?

First, Collie said, is to pay attention to your body. Keep your feet flat on the floor, roll your shoulders back and keep your ears directly over them so your head isn’t bent forward. And use something to support the weight of a mobile device.

Fishman’s Text Neck Institute created a mobile app to help you remember to avoid forward head posture. When your phone is held at a safe point, a green light shines. When you’re at risk for Text Neck, a red light appears.

Most important is taking breaks from time to time while using any mobile device or desktop computer. About every 20 minutes, stand up, roll your shoulders and neck or go for a short walk to have a break.

1What might Fishman mean by saying “I knew I had something”?

A. He had the same smartphone as the patient.

B. He got a new name for the patient’s pain.

C. He wanted to play a joke on the patient.

D. He had the same idea with the patient.
