问题 单项选择题 案例分析题

到2010年底,我国投入运营的高速铁路约7500千米,下图显示我国某段高速铁路景观。据此完成下列各题。

我国高速铁路网建成后,下列区段中,民航客运业受冲击最大的是()

A.武汉──广州

B.杭州──上海

C.成都──上海

D.兰州──北京

答案

参考答案:A

解析:

在不同交通方式中,高铁在中途客运中有优势,航空在长途优势明显,公路运输在短途有优势。武汉-广州、成都-上海、兰州-北京在修高速铁路之前几个城市之间的交通都是以民航为主,民航压力都是巨大的。修高速铁路之后,由于铁路速度加快,价格又低,所以,民航受到的冲击就最大,武汉——广州,距离属于中途,所以冲击最大,A对。而上海到杭州距离属于近途,只有200千米左右,以短途的公路、铁路运输为主,B错。成都——上海,兰州——北京属于远途,受影响小,C、D错。

考点:交通线路选线的原则,交通方式变化的影响。

"The imperative to self-knowledge has always been at the heart of philosophical inquiry," wrote MIT professor Sherry Turkle in the insightful book about the web and the self, Life on the Screen: Identity in the Age of the Internet. Published in 1995 as the second part of a trilogy that examined our relationships with technology, it looked at how we are who we are in online spaces. And what that means for us offline.

The good news is that the results are positive: "Play has always been an important aspect of our individual efforts to build identity," she said, referencing developmental psychologist Erik Erikson, and nodding to the theories of psychoanalysts Freud, Lacan and Jung. "In terms of our views of the self," she wrote, "new images of multiplicity, heterogeneity, flexibility, and fragmentation dominate current thinking about human identity. "

At the time Life on the Screen was released, most of the visitors were college students and their professors from a remarkably small talent pool, and a surprisingly small geography. They were tech-savvy, and generically open-minded about the new fields of virtual exploration that lay within the networks of this new communication platform. They were, in other words, liberal, enlightened types who were more willing to embrace the unprecedented fluidity of self-expression that this new technology uniquely afforded.

As a psychoanalyst and a web user herself, Turkle spent much of the book explaining why the articulation of multiple personalities wasn’t pathological. Contrary to its Latin root, identity need not mean "the same", she argued. "No one aspect can be claimed as the absolute, true self", she wrote, maintaining that the web allowed us the opportunity to get to know our "inner diversity". In the great psychoanalytic tradition, she said that self-actualisation meant coming to terms with who we are, and integrating each aspect of it into a coherent and well-integrated us.

Almost everyone has experienced this kind of identity play. Even if you’ve never ventured into an online game or been a signed-up member of a web community, you’ve probably developed a profile for a social network, written a blog, styled a website, commented on an article. But things are different from the time when Turkle was writing Life on the Screen. Nowadays, our virtual social lives are increasingly integrated. with our offline social lives. The freedom of expression is curtailed by the threat of offline consequences from online actions. Today, your reputation offline is far more closely tied to your reputation online than before. In fact, our experience of contemporary identity online is disarmingly similar to offline.

However, I still subscribe to the old Turkle. Consequence-free online environments allow us to practise and play without fear of offline effect, and offer an extraordinary place to experience the fluidity of our selves: I can be anyone, even a dog. As Tom MacMaster found, there still are places online where this is possible.

It is implied in the second paragraph that()

A. Erikson also explores the role of play in shaping identity

B. modern society takes a positive attitude to psychoanalysis

C. Freud’s psychoanalysis has lost its value in modern society

D. psychologists themselves are confused about human identity
