Ju Wenxuan is a 14-year-old teenager from Shanghai Yangpu Bilingual School. She made a device (装置) to help stop these accidents. “During busy times when I was in the back of a car, it was hard to see if it was safe to open the door,” Ju said. Ju saw that some devices can help with this problem, but they are usually only in newer smart cars. People can’t use them in their older cars. So Ju made a new tool. People can put it on the car’s rearview mirror (后视镜). When people or cars get close, it sounds an alarm (警报) if someone pulls the door handle (把手). Ju also asked people what price they would pay for this tool. Most wanted it to be between 100 and 300 yuan. So she worked hard to lower the cost. She used as few parts as possible to make it cheaper. “If my invention becomes popular, it can stop accidents. It could also help keep kids safe by sounding an alarm if a stranger (陌生人) gets close,” Ju said. ( )1. Ju Wenxuan made a device to help people not hit others when opening the car doors. A. Right. B.
