[单项选择]Students graduating from colleges today are not fully prepared to deal with the" real world". It is my belief that college students need to be taught more skills and information to enable them to meet the challenges that face everyone in daily life. The areas in which students need training are playing the credit game, planning their personal financial strategy, and consumer awareness.
Learning how to obtain and use credit, cardsis probably the most valuable knowledge a young person can have. Credit card is a dangerous tool that can be of tremendous help if it is handled with caution. Having credit cards can enable people to obtain material necessities before they have the money to purchase them. But unfortunately, many young people get carried away with their handy plastic credit cards and awake one day to find they are in serious financial debt. Learning how to use credit cards properly can be a very difficult and painful lesson indeed.
Of equal importance is learning h
A. handle their credit cards with caution
B. control their money carefully so that they don’t go broke
C. make wise purchasing decisions and be informed about consumer services
D. cope with serious financial problems
[单选题]Text 3 In his book The Tipping Point,Malcolm Gladwell argues that social epidemics are driven in large part by the acting of a tiny minority of special individuals,often called influentials,who are unusually informed,persuasive,or well-connected.The idea is intuitively compelling,but it doesn't explain how ideas actually spread.The supposed importance of influentials derives from a plausible sounding but largely untested theory called the"two step flow of communication":Information flows from the media to the influentials and from them to everyone else.Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influentials,those selected people will do most of the work for them.The theory also seems to explain the sudden and unexpected popularity of certain looks,brands,or neighborhoods.In many such cases,a cursory search for causes finds that some small group of people was wearing,promoting,or developing whatever it is before anyone else paid attention.Anecdotal evidence of this kind fits nicely with the idea that only certain special people can drive trends In their recent work,however,some researchers have come up with the finding that influentials have far less impact on social epidemics than is generally supposed.In fact,they don't seem to be required of all.The researchers'argument stems from a simple observing about social influence,with the exception of a few celebrities like Oprah Winfrey—whose outsize presence is primarily a function of media,not interpersonal,influence—even the most influential members of a population simply don't interact with that many others.Yet it is precisely these non-celebrity influentials who,according to the two-step-flow theory,are supposed to drive social epidemics by influencing their friends and colleagues directly.For a social epidemic to occur,however,each person so affected,must then influence his or her own acquaintances,who must in turn influence theirs,and so on;and just how many others pay attention to each of these people has little to do with the initial influential.If people in the network just two degrees removed from the initial influential prove resistant,for example,the cascade of change won't propagate very far or affect many people.Building on the basic truth about interpersonal influence,the researchers studied the dynamics of populations manipulating a number of variables relating of populations,manipulating a number of variables relating to people's ability to influence others and their tendency to be influenced.Our work shows that the principal requirement for what we call"global cascades"–the widespread propagation of influence through networks–is the presence not of a few influentials but,rather,of a critical mass of easily influenced people.34.The underlined phrase"these people"in paragraph 4 refers to the ones who
A.stay outside the network of social influence
B.have little contact with the source of influence
C.are influenced and then influence others
D.are influenced by the initial influential
