Online security cameras, intelligent lighting and a wealth of sensors that control both tempera ture and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business or managing a large building.
We can expect that the ever-growing list of devices, systems and environments remain connected,always online and talking to each other. the big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.
The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.
The good news is that most of this technology is already invented. let\'s face it, it wasn\'t too long ago that the idea of working from anywhere and at anytime was some form of a distant wtopim(乌托邦式的) dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.
It\'s time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.

Section C
Passage One
Question 46 to 50 are based on the following passage.
At the base of a mountain in Tanzania\'s Gregory Rift, Lake Natron burns bright red, surrounded by the remains of animals that were unfortunate enough to fall into the salty water. Bats, swallows and more are chemically preserved in the pose in which they perished, sealed in the deposits of sodium carbonate in the water. The lake\'s landscape is bizarre and deadly- and made even more so by the fact that it\'s the place where nearly 75percent of the world\'s flamingos(火烈鸟) are born.
The water is so corrosive that it can burn the skin and eyes of unadapted animals. Flamingos, however, are the only species that actually makes life in the midst of all that death. Once every three or four years, when conditions are right, the lake is covered with the pink birds as they stop flight to breed. Three –quarters of the world\'s flamingos fly over from other salt lakes in the Rift Valley and nest on salt- crystal islands that appear when the water is at specific level- too high and the birds can\'t build their nests, too low and predators can more briskly across the lake bed and attack. When the water hits the right level. The baby birds are kept safe form predators by a corrosive ditch.
