5 . As reported in JAMA Surgery, the researchers discovered that e-scooter(电动摩托车) injury rates had increased dramatically in just four years, rising from 6 per 100,000 in the population to 19 per 100,000. Of the estimated 14,651 e-scooter-related injuries in 2018, 4,658, or 32%, involved the head. “While most people recover from head injuries, there is going to be a subset with long-term disability and life changes,” said Dr. Benjamin Breyer.

Dr. Benjamin Breyer of the University of California, Los Angeles, pointed to a 2019 analysis of the data from two hospitals in Southern California, which found just 4.8% of injured e-scooter riders were wearing helmets.

Dr. Joann Elmore, a professor of medicine at the University of California, Los Angeles, believed that most e-scooter users are probably unaware of the risks. To 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 helmets. And the woman in front had a baby in a baby carrier.”

The new report highlights the need for more research on new technologies, said Dr. Guohua Li, a professor of epidemiology(流行病学).

“Just as there is a global network of experts working on infectious diseases, there needs to be a similar program devoted to the surveillance(监视，监察) and prevention of injuries caused by merging technologies products and lifestyles, such as e-scooters, e-sports, etc.,” Li said in an email.

“The challenge for researchers and policymakers is to keep up with the ever-changing society and protect the public from unnecessary harm caused by new technologies and products without hindering innovation,” he added.

6 . Joanne was stuck in a traffic jam in central Birmingham at 5:30, and at 6:30 she was expected to be chairing a meeting of the tennis club. At last, the traffic was moving. She swung quickly racing to her house. As she opened the door, she nearly tripped over Sheba.

“Hey, Sheba,” she said, “I’ve got no time for you now, but I’ll take you out as soon as I get back from tennis club.” Then she noticed Sheba seemed to be coughing or choking. Obviously, she could hardly breathe. Immediately, Joanne realized she would have to take her to the vet (兽医). When she got there, the vet was just about to close for the day. Seeing the state of Sheba, Dr. Sterne brought her quickly into his office.

“Listen, doctor, I’m really in a rush to get to a meeting-can I leave her with you, and go and get changed? I’ll be back in ten minutes to pick her up, and then I’ll take her on to the meeting with me. Is that OK?”

“Sure,” said the doctor.

Joanne made the quick trip back to her house in a couple of minutes. As she was once more entering the hallway, the phone by the door began to ring.

“This is Dr. Sterne,” said an anxious voice. “I want you to get out of that house immediately,” said the doctor’s voice. “I’m coming round fight away, and the police will be there any time now. Wait outside!”

At that moment, a police car screeched to a stop outside the house. Two policemen got out and ran into the house. Joanne was by now completely confused and very frightened. Then the doctor arrived.

“Where’s Sheba? Is she OK?” shouted Joanne.

“She’s free, Joanne. I took out the thing which was choking her, and she’s OK now.”

Just then, the two policemen reappeared from the house, half-carrying a white-faced man, who could hardly walk. There was blood all over him.

“My God,” said Joanne, “how did he get in there? And how did you know he was there?”

“I think he must be a burglar,” said the doctor. “I knew he was there because when I finally removed what was stuck in Sheba’s throat; it turned out to be three human fingers.”
