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.

1.The underlined part “ a catch” (in Paragraph 2) probably means “________”.

A. a rare challenge                         B. a desirable plan

C. an efficient device                       D. a hidden problem

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.

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

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.

Often we take for granted the many household items we use every day. It is difficult to imagine there was a time in the past when these inventions did not exist. Actually, several of the most common inventions have been with us for quite some time. Inventions like toothbrush, contact lenses（隐形眼镜）, and credit cards came into use long ago.

The first toothbrush was introduced in China in the late 1400s but it was only 300 years later that this simple tool came into common use in Europe. By the nineteenth century, a variety of paste and powder cleaners were available throughout Europe as dental(牙齿的) care became more widespread. The first tube of toothpaste hit the market in Great Britain in 1891.

There is evidence to show that the first contact lenses were actually suggested by an astronomer, Sir John Herschel, in 1827. However, SirJohn Herschel was never able to create a working model of his idea. It was not until 1887 that a Swiss doctor from Zurich, Dr. Eugen Frick, came up with a workable process for producing precision (精密)lenses. Dr. Frick designed a new method for producing contact lenses,and the Zeiss factory in Germany  began to produce contact lenses.

Credit cards have also been available for many years. They have been in use in the United States since the 1920s. At first, these cards were only used to buy gas in the quickly growing automobile service industry. Then, in the 1950s, Diners Club introduced the first general-purpose credit card. Today, credit cards such as Master Card, Visa, and American Express are commonly used by travelers around the world.

While it may be true that some of the greatest inventions and discoveries in history came about by chance, the majority of inventions that simplify our lives today came about through careful research and patient study. Of course, it still holds true that even with all the comforts of modern technology, inventors continue to search for ways of helping all of us get out of doing those necessary but tedious (乏味的) tasks which we still face. As the old saying goes, “Necessity is the mother of invention.”

1.From the second paragraph we can learn that _____.

A. toothbrushes came into common use in Europe in the 17th century

B. people could enjoy a variety of paste and powder cleaners in the 18th century

C. more and more people paid attention to dental care throughout Europe in the 19th century

D. the English could use different kinds of tubes of toothpaste in the early 19th century

2.All of the following made a contribution to the invention and use of contact lenses EXCEPT _______.

A. Diners Club                       B. Sir John Herschel

C. Dr Eugen Frick                    D. the Zeiss factory

3.Which of the following statements is TRUE according to the fourth paragraph?

A. Credit cards have a history of about two hundred years.

B. Three kinds of credit cards are being used in the USA.

C. The use of credit cards is closely related to the economic development.

D. American Express is only used by American travelers now.

4.The last paragraph mainly tells us that ______.

A. the greatest inventions came about by chance

B. inventions came about through careful research and patient study

C. inventors still continue to make inventions
