（二）Electric Scooter injuries rising, one-third involve the head
As 1_____________(report) in JAMA Surgery, the researchers discovered that e-scooter injury rates had increased dramatically(急剧地) in just four years: the incidence more than doubled during those years, 2___________(rise) from 6 percent 100,000 in the population to 19 per 100,000. of the estimated 14,651 e-scooter-related 3______________(injury) in 2018, 4,658 or 32%, involved the head.  
Dr. Benjamin Breyer of the University of California, Los Angeles, points to a 2019 analysis of data from two hospitals in Southern California, 4_____________ found just 4.8% of injured e-scooter riders 5____________(wear) helmets. Dr. Joann Elmore, a professor of medicine at the University of California, Los Angels, believed that most e-scooter 6___________(use) are probably unaware of the risks. 7____________(make) the point, she described a photo taken by a colleague. “There were two riders on an e-scooter,” she said. “No one had shoes on. There were no 8_____________(helmet). and the woman in front had a baby in a Baby Bjorn.”
The new report 9_______________(highlight) the need for more research on new technologies, said Dr. Guohua Li, a professor of epidemilogy(流行病学) at Columbia University’s Mailman School of Public Health in New York City. Just as there is 10____________(globe) work of experts working on infectious diseases, there needs 11___________(be) “a similar program 12______________(devote) to the surveillance(监管) and prevention of injuries 13_____________(cause) by emerging(新兴的) technologies, products and lifestyles, such as e-scooters, e-sports, etc.” Li said in 14_________ email. “The challenge for researchers and policy-makers is to keep up with the ever-changing society and protect the pubic from 15______________(necessary) harms caused by new technologies and products without hindering(阻碍) innovation.” he 16___________(add).
