Passage Three
Texting while driving was listed as a major cause of road deaths among young Americans back in 2013.

A recent study said that 40% of American teens claim to have been in a car when the driver used a cell phone in a way that put people in danger.
最近的一项研究表明，40%的美国青少年声称，都乘坐过用手机将他们置于危险中的司机的车。
This sounds like a widespread disease，but it's one that technology may now help to cure.
这听起来像一个通病，但现代技术却可以帮助治愈这种通病。
T. J. Evarts, a 20-year-old inventor, has come up with a novel solution that could easily put texting drivers on notice.
20岁的T. J. Evarts是一名发明家，想出了一个很容易让发短信的司机注意到的新奇法子。
It's called Smart Wheel, and it's designed to fit over the steering wheel of most standard vehicles

to track whether or not the driver has two hands on the wheel at all times.
以跟踪司机是否在任何时候都有两只手在方向盘上。
Evarts'invention warns the drivers with a light and a sound when they hold the wheel with one hand only,
这是Evarts公司的发明，当驾驶员单手驾驶时，“智能方向盘” 就会亮灯并发出声音以示警告，
but as soon as they place the other hand back on the wheel, the light turns back to green and the sound stops.
但一旦他们把另一只手放回方向盘上，灯光就会变回绿色，声音也会停止。
It also watches for what's called "close-by hands," where both hands are close together near the top of the wheel,
在双手靠近“智能方向盘”顶部的地方，方向盘套还会监视所谓的“附近的手”，
so the driver can type with both thumbs and drive at the same time.
这样司机就可以用两个大拇指打字的同时开车了。
All the data Smart Wheel collects is also sent to a connected app.
“智能方向盘”收集的所有数据都会传到连接的应用程序。
So any parents who install Smart Wheel can keep track of the teen's driving habits.
