A Positive Example

　　Early this year, owners of the Tesla Models electric car received a recall notice alerting them to a charger plug needing to be fixed. Amazingly, owners of the Models sat back while the company performed an “over the air” wireless update. Customers confirmed the update by tapping on the car’s touchscreen console to see that the Models was running the latest software version. No trip to the dealer was required!

　　Perhaps Tesla’s remote fix is a sign of things to come. Someday soon, people’s lives might become a lot more efficient and convenient thanks to the IOT.

　　【文章大意】本文介绍什么是物联网以及物联网的缺点和优点。

　　1. How do researchers get everything and everyone talking?

　　A. By establishing the IOT and launching a handful of sensors.

　　B. By connecting sensors with them and appointing them unique IP addresses.

　　C. By communicating with them all the time through the IOT.

　　D. By sending people to track them day and night and collect useful data.

　　【解析】选B。细节理解题。根据第一段提到Attaching sensors to“things”, such as cows, cars and refrigerators, and then assigning them unique IP addresses allow them to “talk” to the Internet. 可知传感器与东西联系在一起, 分配给它们IP地址, 这样就能让它们通过网络对话, 故选B项。
