1、大学英语四级模拟试卷 1008(无答案)一、Part I Writing (30 minutes)1 For this part, you are allowed 30 minutes to write a short essay entitled Is It Necessary to Continue Military Training for Freshmen? You should write at least 120 words following the outline given below.1目前,各高校均对大一新生进行军训2有人赞成,有人反对3我的观点Is It Necessa
2、ry to Continue Military Training for Freshmen?二、Part II Reading Comprehension (Skimming and Scanning) (15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-7, mark:Y (for YES) if the statement a
3、grees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage;NG (for NOT GIVEN) if the information is not given in the passage.1 Googles Google problemGoogle is killing Google Reader. Use of Google Reader, a tool, by the way, for readin
4、g online content via RSS was concentrated among a small group of relatively intense users. As it happens, that small group includes quite a lot of people who write for or as part of their living. And so Google Reader has been mourned over, angrily at times, a bit more than the many other Google serv
5、ices that have come and gone.It isnt that hard to imagine what Google was thinking when it made this decision. Its a big company, but even big companies have finite resources, and devoting those precious resources to something that isnt making money and isnt judged to have much in the way of develop
6、ment potential is not an attractive option. Dropping Reader isnt going to hurt the companys business.Yet this little contretemps(令人尴尬的事)may suggest bigger trouble ahead for Google and big changes for the internet. One immediate effect is relatively easy to anticipate. John Hempton makes a nice point
7、 here: Google is in the process of abandoning its mission. Googles stated mission is to organize all the worlds information and make it universally accessible and useful. Google no longer cares. It seems what they care about is mass-markets.Google has asked us to build our lives around it: to use it
8、s e-mail system, its search engines, its maps, its calendars, its cloud-based apps and storage services, its video- and photo-hosting services, and on and on and on. Google wants us to use its services in ways that provide it with interesting and valuable information, and eyeballs. If a particular G
9、oogle experiment isnt cutting it in that category, then Google may feel justified in axing it.But that makes it increasingly difficult for Google to have success with new services. Why commit to using and coming to rely on something new if it might be pulled away at some future date? This is especia
10、lly problematic for “ social“ apps that rely on network effects. Even a bad social service may thrive if it obtains a critical mass. Yanking away services beloved by early adopters almost guarantees that critical masses cant be obtained: not, at any rate, without the provision of an incentive or com
11、mitment mechanism to protect the would-be users from the risk of losing a vital service.There may be bigger implications still, however. As I said, Google has asked us to build our lives around it, and we have responded. This response entails(势必导致)a powerful self-reinforcement mechanism: both provid
12、ers and users of information and other services change their behaviour as a result of the availability of a Google product. You can see this on a small scale with Reader. People design their websites and content based on the assumption that others, via an RSS reader, will come across and read that c
13、ontent in a certain way. And readers structure their reading habits, and ultimately their mental models of what information is available and where, based on the existence of this tool. If you then pull away the product at the heart of that system, you end up causing significant disruption(混乱), assum
14、ing there arent good alternatives available.The issue becomes a bit more obvious when you think about something like search. Many of us now operate under the assumption that if we want to find something we will be able to do so quickly and easily via Google search. If I want an idea for a unique gif
15、t for someone, I can put in related search terms and feel pretty confident that Ill get back store websites and blogs and Pinterest pages and newspaper stories and pictures all providing possible matches.If Im a researcher, I know I can quickly find relevant academic papers, data, newspaper accounts
16、, expert analysis, and who knows what else related to an enormous range of topics. Once we all become comfortable with that state of affairs we quickly begin optimising(优化)the physical and digital resources around us. And once we all become comfortable with that, we begin rearranging our mental arch
17、itecture. We stop memorising key data points and start learning how to ask the right questions. We begin to think differently. We stop keeping a mental model of the physical geography of the world around us, because why bother? We can call up an incredibly detailed and accurate map of the world, com
18、plete with satellite and street-level images, whenever we want. The bottom line is that the more we all participate in this world, the more we come to depend on it.What Google has actually done is create a powerful infrastructure(基础设施). The shape of that infrastructure influences everything that goe
19、s online. And it influences the allocation of mental resources of everyone who interacts with the online world. But there isnt much to the real human world that isnt shaped by the mental activity of the people in it!Thats a lot of power to put in the hands of a company that now seems interested, mos
20、tly, in identifying core mass-market services it can use to maximise its return on investment. Now in the short run, that may mostly be a problem for all of us. To the extent that we become worried about this phenomenon, we may go out and find back-up services or other alternatives. This will be les
21、s convenient and more costly, in terms of time and money, but those sufficiently foresighted(预见的)might feel its a better option than opening up gmail one day to read that the email service, and the 10-years worth of communication it holds, will soon be gone.But in the long run thats a problem for Go
22、ogle. Because we tend not to entrust(委托)this sort of critical public infrastructure to the private sector. Network externalities are all fine and good to ignore so long as they mainly apply to the sharing of news and pictures from a weekend trip with college friends. Once they concern large amount o
23、f economic output and the cognitive activity of millions of people, it is difficult to keep the government out. Maybe that obstacle will be sufficient to keep Google providing its most heavily used products. But maybe not.I find myself thinking again of the brave new world of the industrial city, wh
24、en new patterns of interaction led to enormous changes in economic activity, in culture and personal behaviour, and in the way we think. We upgraded ourselves, in terms of education and social norms, to maximise the return to urban life. I think we, meaning users of the web and the companies that pr
