If you feel a small bony bump (突起), you will find evidence of human evolution: it could be your body responding to common smartphone use in the 21st century.According to a recent study, published in Scientific Reports, young people increasingly have bony bumps at the base of their skulls (颅骨) right above the neck. Medical professionals call them enlarged external occipital protuberances(EEOPs, 枕外隆突).Australian health scientist David Shahar, author of the study told the BBC that over the past 10 years, he’s seen more and more patients with EEOPs. Together with other researchers from the University of the Sunshine Coast, Australia, they examined 1200 skulls x-rays from people aged 18 to 30. They also measured the bumps and noted each person’s posture (坐姿).They found that one in four people have developed these growths. This led to their theory that smartphones are the cause.According to their research, looking down at their phones adds the stress onto the top of our spines (脊柱). To prevent damage to our spines, Shahar believes our bodies add fresh bony bumps to help reduce the extra stress.Most of the EEOPs measurea just a few millimeters. However, several subjects were found with EEOPs as large as 30 mm.In his report, Shahar said the results “highlighted the need” for prevention. In other words, we need to change our posture while using our phones.Many people assume our bones are solid and are unmoving once we reach adulthood. In reality, they are alive and covered with blood vessels (血管), which allows them to develop in unique ways for each person.Aside from EEOPs, other noticeable recent changes in human bodies include smaller jaws, elbows and skeletons (骨格). The human body is changing with modern life. So who knows what people in the future might look like?【1】What did the recent study find about EEPOs?A.They grow on one’s neck.B.They could lead to many mental problems.C.They increasingly occur among young people.D.They may stop growing when they reach 30.【2】What is the main cause of EEPOs?A.Gene problems.B.Cellphone use.C.Blood vessels.D.Extra stress.【3】Which of the following would Shahar probably agree with?A.EEPOs increase the stress on our spines.B.Young people’s bones develop in similar ways.C.EEPOs are actually beneficial to our spines.D.Young people should exercise to improve their posture.【4】What’s the main purpose of the text?A.To persuade readers to protect their spines.B.To recommend some healthy habits of using phones.C.To show some recent changes in human bodies.D.To explain why human bodies develop EEPOs.
