Can privacy be preserved (2) bringing safety and security to a world that seems increasingly (3) ?
Last month, Howard Schmidt, the nation's cyber-czar, offered the federal government a (4) to make the Web a safer place a "voluntary trusted identity" system that would be the high-tech (5) of a physical key, a fingerprint and a photo ID card, all rolled (6) one. The system might use a smart identity card, or a digital credential (7) to a specific computer, and would authenticate users at a range of online services.
The idea is to (8) a federation of private online identity systems. User could (9) which system to join, and only registered users whose identities have been authenticated could navigate those systems. The approach contrasts with one that would require an Internet driver's license (10) by the government.
Google and Microsoft are among companies that already have these "single sign-on" systems that make it possible for users to (11) just once but use many different services.
(12) , the approach would create a "walled garden" cyberspace, with safe "neighborhoods" and bright "streetlights" to establish a sense of a (13) community.
Mr. Schmidt described it as a "voluntary ecosystem" in which "individuals and organizations can complete online transactions with (14) ,trusting the identities of each other and the identities of the infrastructrue (15) which the transaction runs".
Still, the administration's plan has (16) privacy rights activists. Some applaud the approach; others are concerned. It seems clear that such a scheme is an initiative push toward what would (17) be a compulsory Internet "drive's license" mentality.
The plan has also been greeted with (18) by some computer security experts, who worry that the "voluntary ecosystem" envisioned by Mr. Schmidt would still leave much of the Internet (19) . They argue that all Internet users should be (20) to register and identify themselves, in the same way that drivers must be licensed to drive on public roads.

A second aspect of the Web is that it is the first medium that honors the notion of multiple intelligences. This past century's concept of literacy grew out of our intense belief in text, a focus enhanced by the power of one particular technology-the typewriter. It became a great tool for writers but a terrible one for other creative activities such as sketching, painting, notating music, or even mathematics. The typewriter prized one particular kind of intelligence, but with the Web, we suddenly have a medium that honors multiple forms of intelligence—abstract, textual, visual, musical, social, and kinesthetic. As educators, we now have a chance to construct a medium that enables all young people to become engaged in their ideal way of learning. The Web affords the match we need between a medium and how a particular person learns.
A third and unusual aspect of the Web is that it leverages (起杠杆作用) the small efforts of the many with the large efforts of the few. For example, researchers in the Maricopa County Community College system in Phoenix have found a way to link a set of senior citizens with pupils in the Longview Elementary School, as helper-mentors (顾问). It's wonderful to sec-kids listen to these grandparents better than they do to their own parents, the mentoring really helps their teachers, and the seniors create a sense of meaning for themselves. Thus, the small efforts of the man—the seniors—complement the large efforts of the few—the teachers. The same thing can be found in operation at Hewlett-Packard, where engineers use the Web to help kids with science or math problems. Both of these examples barely scratch the surface as we think about what's possible when we start interlacing resources with needs across a whole region.
What does the word mind-stretching imply?
A.Obtaining one's mental power.
B.Strengthening one's power of thought.
C.Making great demands on one's mental power.
D.Exerting one's mental power as far as possible.
