【 The Internet ofthings (IoT) is the inter-networking ofphysical devices，vehicles ，buildings ，and other items embedded with electronics ，software，sensors，actuators，and network connectivity which enable these objects to collect and exchange data. In 2013 the Global Standards Initiative on Internet ofThings (IoT-GSI) defined the 10T as " a global infrastructure for the information society， enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable information and communication technologies" and for these purposes a "thing" is "an object ofthe physical world (physical things) or the information world (virtual things). which is capable ofbeing identified and integrated into communication networks". The 10T allows objects to be sensed or controlled remotely across existing network infrastructure ，creating opportunities for more direct integration of the physical world into computer - based systems，and resulting in improved efficiency. Accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators，the technology becomes an instance of the more general class of cyber physical systems，which also encompasses technologies such as smart grids，virtual power plants ，smart homes ，intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Intemet infrastructure. Experts estimate that the 10T wi l1 consist of about 30 bi l1ion objects by 2020. 】 Based on the paragraph above，we know that the applications ofthe 10T include (98) . RFID technology makes it possible to automatically (99) every object on the Internet ofthings，and is the foundation ofnetworking. From the industry point of view，IoT is mainly involved in industries including (100).
A. environmental monitoring B.intelligent transportation C.energy management D.all ofthe above A. identify B.find C. track D. encrypt A. electronics B.communication C. software D. all of the above
This survey has presented the arguments for more private funding and for fairer pensions. Such changes will create motives for individuals to take charge of their own retirement needs rather than leaving the task to the state. This, in turn, will make the provision of public pensions more afford- able.
Even so, the state will continue to play a leading role in pensions. At a minimum, governments must offer a safety net, probably in the form. of a defined benefit financed through taxation, for people who for some reason have not been able to provide for themselves and who would otherwise be miserable in old age. More broadly, there is a case for the state to offer a slimmed-down pay-as-you-go pension system, although as far as possible this should be organized along defined-contributions lines. Such provision widens the range of assets to include human capital because the effective return comes from total wages, and offers a safe if low return.
Governments also have to create a suitable framework for effective private pensions. Administrative(行政的)expenses have to be tightly controlled, and appropriate tax motives have
to be offered to encourage voluntary pension saving. Where the state provides a generous safety net, private-pension saving may have to be made mandatory(强制的) , otherwise many people will not bother.
So much for the developed countries, but what of the more youthful populations of tile rest of the world？ In 1994, the World Bank came down heavily in favor of more funding in private accounts. It thought the state's role should be to provide a smallish first pillar with the limited task of providing protection against old-age poverty, and to command a privately-funded second pillar to provide the bulk of pensions.
More private funding and fairer pensions______.
A．can urge people to save more private-pensions
B．may be financed through tax
C．can lessen the burden of the state
D．can provide more public pensions
