问题     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.
【C13】
选项 A、parking
B、restaurant
C、hotel
D、destination
答案D
解析 connect…to the Web表明汽车联网能搜寻相关信息。such as后则举例说明是何种信息。D项destination“目的地”符合语义要求，指汽车具备了目的地搜寻功能，也能对应上文infrastructure(基础设施)和roadways(道路)等词。A项parking“停车场”、B项restaurant“餐馆”和C项hotel“酒店”都表示具体的地点。可归属于destination范畴。此处的语境没有具体指向某一地点。
