71.What may eventually settle the “last mile problem? A.The broadband connection’s getting faster. B.More and more Internet users. C.more and more Internet connections. D.The rapid progress in cell phone technology. 答案:68-71 DDCD Passage 3 (河北省正定中学2010高三下学期第二次月考C篇) Our brains work in complex and strange ways. There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two. Others can perform complex classical piano pieces after hearing them once, but they cannot read or write. Dr.J.Langdon Down first described this condition in 1887.He called these people idiot savants. An idiot savant is a person who has significant mental impairment , such as in autism or retardation. At the same time, the person also exhibits some extraordinary skills, which are unusual for most people.The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory. One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr.Benjamin Rush, an American doctor.His patient, Thomas Fuller, was brought to Virginia as a slave in 1724. It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds.Despite this ability, he died in 1790 without ever learning to read or write. Another idiot savant slave became famous as a pianist in the 1860s. Blind Tom had a vocabulary of only 100 words, but he played 5 ,000 musical pieces beautifully. In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly. Today we more clearly recognize that the idiot savant is special because of brain impairment.Yet not all brain impairment leads to savant skills.Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills. However,few people wish to participate in such experiments. There are many excellent reasons for not undergoing unnecessary experimentation on one's brain. The term idiot savant is outdated and inappropriate. Virtually all savants have a high degree of intelligence and are thus not idiots. 查看更多

 

题目列表(包括答案和解析)

In the computer age, most of us take a broadband Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course. You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely(稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere. Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables(光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication(迹象), it may not be too long before an Internet connection simply follows you wherever you go.
【小题1】The underlined part “ a catch” (in Paragraph 2) probably means “________”.

A.a rare challengeB.a desirable plan
C.an efficient deviceD.a hidden problem
【小题2】What can we know from the third paragraph?
A.Internet connection has not been popular in most cities.
B.Internet service providers care about rural customers.
C.Computer is popular in developing countries.
D.It is hard to bring Internet access to users in remote areas.
【小题3】 Paragraph 4 mainly tells us that technological advancements ________.
A.make TV and telephone available everywhere
B.bring great change to people’s everyday life
C.make it possible for more people to use the Internet
D.bring faster Internet connections to users
【小题4】What may eventually settle the “last mile” problem?
A.The broadband connection’s getting faster.
B.More and more Internet users.
C.More and more Internet connections.
D.The rapid progress in cell phone technology.
