What if those new jeans you've just bought start tweeting(吱吱地叫)about your location as you cross London Bridge?
It sounds far-fetched, but it's possible－if one of your coats is equipped with a tiny radio-frequency identification device(RFID), your location could be revealed without you knowing about it．
RFIDs are chips that use radio waves to send data to a reader－which in turn can be connected to the web．
This technology is just one of the current ways of allowing physical objects to go online－a concept called the “Internet of things”, which industry insiders have shortened to IoT．
This is when not only your PC, tablet and smartphone can connect to the web, but also your car, your home, your baseball cap and even the sheep and cows on a farm．
Smart buildings and intelligent cars with assigned IP addresses are already making cities smarter－and soon enough, the entire planet may follow．
“A typical city of the future in a full IoT situation could be a place with smart cameras everywhere, neurosensors(神经监测系统)scanning your brain for over-activity in every street,” says Rob van Kranenburg, a member of the European Commission's IoT expert group．
This vision might still be years off, but one by one, “smarter” cities are beginning to crop up around our landscape．
IoT advocates claim that overall interconnectivity would allow us to locate and monitor everything, everywhere and at any time．
“Imagine a smart building where a manager can know how many people are inside just by which rooms are reflecting motion－for instance, via motion-sensitive lights,” says Constantine Valhouli from the Hammersmith Group, a strategy consulting firm．
“This could help save lives in an emergency．”
But as more objects go into the digital world, the fine line that separates the benefits of increasingly smart technology and possible privacy concerns becomes really blurred．
“The IoT challenge is likely to grow both in scale and complexity as seven billion humans are expected to coexist with 70 billion machines and perhaps 70,000 billion ‘smart things', with numbers invading the last fences of personal life,” says Gerald Santucci, head of the networked enterprise and RFID unit at the European Commission．
“In such a new context, the worries increase：to what extent can monitoring of people be accepted? Which principles should govern the deployment of the IoT?”

To take the apple as a forbidden fruit is the most unlikely strory the Christians(基督教徒)ever cooked up．For them, the forbidden fruit from Eden is evil(邪恶的)．So when Colu brought the tomato back from South America, a land mistakenly considered to be eden, ever jumped to be the obvious conclusion．Wrongly taken as the apple of Eden, the tomato was shut o the door of Europeans．

But in the end tomatoes carried the day．The hero of the tomato was an American named R Johnson, and when he was publicly going to eat the tomato in 1820, people journeyed for hun of miles to watch him drop dead．”Wha are you afraid of?”he shouted．”I'll show you fools these things are good to eat!” Then he bit into the tomato．Some people fainted．But he sur and, according to a local story, set up a tomato-canning factory．
