Could your smartphone prevent a car from hitting you? General Motors and other researchers think that’s a possibility【C1】________an emerging wireless standard works its way into the latest smartphones and new cars.
First seen in 2010, Wi-Fi Direct【C2】________ultrafast device-to-device connections over the same radio waves that smartphones, computers and other electronics currently use to connect to routers and home networks. The【C3】________here is that unlike your application-enabled television, Wi-Fi Direct doesn’t【C4】________the Internet. Rather, it’s【C5】________connect local devices directly to each other【C6】________as little as a second, and unlike Bluetooth, the connection doesn’t require special pass keys and works at more than double the【C7】________, at about 656 feet apart. GM says future cars could【C8】________pedestrians carrying Wi-Fi Direct smartphones, gather their【C9】________locations and warn the driver through existing active safety systems such as forward collision【C10】________and auto-braking.
Wi-Fi Direct is one part of GM’s research on vehicle-to-vehicle and vehicle-to-infrastructure【C11】________in which both cars and roadways become【C12】________aware and adaptive to real-time information. More and more automakers, such as BMW and Hyundai, use a subscription-based 3G cell network to connect a car’s information & entertainment system to the Web for things such as【C13】________searches. A few automakers, such as Ford and Audi,【C14】________wireless hotspots that allow full【C15】________to the Internet from any mobile device. By 2015, Ford said it【C16】________80 percent of the vehicles it sells in North America to have a Wi-Fi connection.
Wi-Fi Direct currently allows file【C17】________between two electronic devices【C18】________having to pair them. If the technology becomes popular and【C19】________it could pull the market away from Bluetooth, the short-range wireless standard for in-car telephone calls and portable audio. With Bluetooth, there isn’t one【C20】________way to connect a device—and many times, as we’ve often found, it still doesn’t work. According to data from the National Highway Traffic Safety Administration, nearly 4,900 pedestrians and cyclists were killed by cars last year, for which data were available.
【C20】
选项
A、clear
B、unique
C、complex
D、simple
答案
D
解析
上文提到Wi-Fi Direct的优势:不用密码、不用配对,可见其优势是操作简单。因此可推测文章认为蓝牙技术连接方式趋于复杂。句中谓语isn’t含有否定意义,故空格处应是与“复杂”意义相反的词,用D项simple“简单的”。蓝牙技术需要配对,它的连接方式显然是“明确的”,因此排除A项clear。对于蓝牙技术而言,其关键是要能让设备间实现相互连接和数据传递,而不能要求它必须是“独一无二的”,因此B项unique不对。C项complex“复杂的”与isn’t搭配后与文意相反。
