(C)
Scientists say that smartphones are changing the shape of people's skulls（头骨）. Some people are spending so long looking at smartphones that a small bony bump（骨头突起）is appearing above their neck. Doctors say the bump is large enough to feel by pressing the bottom of the skull, just above the neck. Dr. David Shahar, a health scientist at the University of the Sunshine Coast in Australia, spoke to the BBC about the discovery. He said,“I have been a doctor for 20 years, and only in the last ten years, increasingly, I have been discovering that my patients have this growth on the skull.”The bump is being more commonly seen among 18 to 30 - year - olds who spend many hours a day over their smartphone.
A study led by Dr. Shahar looked at the smartphone use of 1,200 people aged 18 to 86. Shahar said 18 to 30 - year - olds were more likely to have the skull bumps than older generations（一代人）. He said the bumps would probably be more common as we spend longer bending（弯曲）our necks while looking at their phones. Doctors say the bump could come from bending the neck at unnatural angles（角度）to look at smartphones. Our head weighs about 4.5 kilograms and bending our head at the same angle for a long time can hurt the neck. Doctors are calling this hurt “text neck”. They advised people to change their posture if their neck becomes sore.
