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.
68. 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
69. 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.
70. 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
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.

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.

"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

1.What can we learn from the first paragraph?

A．Bikes should be made more comfortable to ride.

B．You can improve your bicycle for science research.

C．Many inventions are connected with the bicycle.

D．Bicycles are the best way to go about

2.Which of the following is true according to the passage?

A．ISEF is an exhibiton displaying bicycle experiments designed by students.

B．Looking closely at things you are concerned about can lead to scientific research.

C．Renato’s improvement of the bicycle has solved the country’s great problem.

D．Renato’s special bicycle will soon be put into use in remote areas.’

3.The underlined word “address” in the third paragraph probably has the same meaning as _______.

A．make address written

B．give up

C．work at

D．speak at

4.Renato’s special Multibike has all the following EXCEPT ________.

A．making knives sharp	B．mixing any kind of drinks
C．producing electricity	D．operating a machine with its own electricity

5.It can be inferred that Renato’s special bicycle is mainly designed for ________.

A．distant areas in the rainforest without electricity.

B．the use of his own family to make life easier.

C．the competition of ISEF to win money to support remote rainforests

D．enough exercise by pedaling it

In most situations, light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution. It prevents our view of some of life’s most striking sights: stars, planets, and even galaxies.

“When I was a little boy, I loved the night sky. I remember looking up and the sky was filled with stars. I became an astronomer because I was amazed by their beauty,” says Robert gent, “Now in most big cities kids can’t see the stars like I did.”

Normally, about 2,500 individual stars are visible to the naked eye without using any special equipment. But because of light pollution, you actually see just 200 to 300 and fewer than a dozen from some cities. Only one in three Americans can see our own galaxy (星系) with the naked eye. Those people live far away from the lights of big cities, office building, and shopping malls.

Fortunately, there’s an inexpensive and useful way. If we shine lights down at the ground instead of up into the sky, and use lower brightness levels, we can save big amounts of energy and keep the beauty of the night skies. Many cities and towns have passed laws limiting lights at night, making sure enough shine for safety without creating much light pollution.

Light pollution affects more than our view of the heavens and can harm wildlife. Migrating (迁移) birds sometimes fly over cities and become confused by the brightness, flying in circles until they drop from exhaustion. Sea turtles need dark beaches for nesting and won’t approach bright lights. Too much light at night may even affect human health. For all these reasons, researchers are working on ways to use light only when and where they are truly needed. Everyone deserves to look up at the sky.

1.According to the text, using our naked eyes, ______________.

A．people in remote areas can see more stars than those in big cities

B．over one third Americans can see our own galaxy

C．about one in three Americans in big cities can see our own galaxy

D．Americans can only see 200 to 300 stars

2.Many cities and towns have passed laws limiting lights at night mainly to _________.

A．save the electricity	B．make sure of cities’ safety
C．let you count the number of stars	D．avoid much light pollution

3.In how many ways will the light pollution do harm?

A．One

B．Two

C．Three

D．Four

4.The underlined word “exhaustion” in the last paragraph means “_________”.

A．air pollution

B．tiredness

C．breath

D．brightness
