Looking back, for example, to the twenties and thirties, we can see that circulation managers unerringly diagnosed the twin obsessions which dominated that era of mass unemployment -- economic insecurity and a passionate concern for the next generation. Thus it was that readers were recruited with offers of free insurance policies for the one, and free instant education for the other. The family whose breadwinner lost an eye in a double railway derailment, or an arm in a flood, could confidently expect to collect several hundred pounds from the Daily This or the Evening That. The family who could not afford to send their son to grammar school could find consolation in equipping him with the complete works of Shakespeare in one magnificent, easy-to-read volume.
After the war the need to fall into step with the new consumer society was soon realized. If you were flanked by neighbors who, unlike you, could afford a holiday abroad, then winning an easy competition could set you up with a fortnight in an exotic sunspot. Dishwashers, washing machines, slow-cookers and deep-fat-friers were -- and still are -- available by the same means.
The writer finds the study of gifts and prizes interesting because it______
A.reveals social trends
B.exposes journalistic dishonesty
C.confirms his view of human nature
D.shows the power of the popular press

A public good is one that a person can use without reducing the use of it for another person. One of the best examples of a public good is national defense. One person can benefit from our national defense without reducing another person's benefits. In fact, it is difficult to keep any person in our society from enjoying the benefits of national defense.
The market system does not work well in producing public goods. This is because a person who refuses to pay for a public good can not be kept from using it. Suppose that the neighbors in a high crime area decide to hire a police force. Each neighbor, except Mrs. Smith, agrees to pay $100 a year for it. Mrs. Smith refuses to pay because she knows that if all the others pay the $100, the police will guard the area anyway. So Mrs. Smith can enjoy the services of the police force without paying $100. The market system has no way to deal with this type of problem. For this reason, we can not ask each person to make a direct payment in the form. of product price. Therefore, we collect money for public goods by using taxes.
According to the passage, public goods are______.
A.services enjoyed by all people
B.what we can buy and sell in public
C.products that we make for national defense
D.taxes paid by the people involved

【 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
