The Internet of Things is opportunistic in that it will use the network infrastructures that are available without prejudice.,12,Text A: The Internet of Things,Whats the point of all this new
8、 object data from the Internet of Things? As well as the new types of functionalities it will enable, the sheer amount of new data about an object should lead to better quality goods and better decision-making by consumers. For example when you buy a loaf of bread from the grocery store, it will hav

10、angers), and much more information.,13,Text A: The Internet of Things,With all objects in the world equipped with minuscule identifying devices, daily life on Earth would undergo a transformation. Companies would not run out of stock or waste products, as all involved parties would know exactly whic

Mislaid and stolen items would be easily tracked and located.,14,Text A: The Internet of Things,What is important is that the term Internet in Internet of Thing is used in a different way then it is when speaking of the Internet qua Internet.

What is importan
16、t is that the term Internet in Internet of Thing is used in a different way then it is when speaking of the Internet qua Internet. 译文：值得一提的是，物联网中的网络和我们平时提到的互联网是不同的。 句中，“What is important”为主语从句，做这句话的主语。 4.
