The Grand Canyon (峽谷) in Arizona extends four hundred fifty kilometers. The canyons look as if they formed as the earth split apart. They were actually cut by rivers.
Looking at the Grand Canyon is like looking back in time. Forty million years ago, the Colorado River began cutting through the area. At the same time, the surrounding land was pushed up by forces deep within the Earth. Rain, snow, ice, wind, and plant roots rubbed away at the top of the new canyon. Below, the flowing river continued to uncover more and more levels of ancient rock. Their appearance changes endlessly -- with the light, the time of year, and the weather.
The Grand Canyon has several weather environments. The top is often much different from the bottom. On some winter days, for example, you may find cold winds and snow at the top. But at the bottom, you may find warm winds and flowers.
The Grand Canyon is known as one of the seven wonders of the natural world. About five million people visit the canyon each year. Most visitors walk along paths part way down into the canyon. Some visitors ride mules to the bottom and back.
There are several other ways to visit the Grand Canyon. Hundreds of thousands of people see the canyon by air each year. They pay a helicopter or airplane pilot to fly them above and around the canyon.
About twenty thousand people a year see the Grand Canyon from the Colorado River itself. They ride boats over the rapid, rocky water. These trips last from one week to three weeks.
Visitors can see the Grand Canyon in still another way. A huge glass walkway, called the Skywalk, extends from the edge and is hanging above the bottom of the canyon.
Some people say the Skywalk is an engineering wonder. However, other people have criticized the Skywalk and future development. They say it harms a national treasure and reduces the enjoyment of nature in the Grand Canyon.

For many blind people, computers are inaccessible. It can cost $1,000 to purchase “screen reader” software, but two blind computer programmers from Australia have solved this problem.
Queensland University of Technology (QUT) graduate James Teh and business partner Michael Curran developed a free, open-source program, called NVDA, which provides a voice to read the words on a computer screen as the cursor(光標(biāo)) moves over them. NVDA won the blind inventors an award in the grand final program of the ABC’s New Inventors, which aired on September 23. They took home the award for an invention that “might make a real difference to people’s lives or the environment.”
“A sighted person takes for granted that they can sit down at any computer and use it,” Mr Teh said. “We really are in the information age — everything is online these days. So access to computers for the blind is very important, which is why we wanted our software to be free.”
Mr Teh, who majored in software engineering at QUT, said blind students typically didn’t have the money to purchase “screen reader” technology, at the time in their life when they most needed it. Now NVDA could be downloaded on to anyone’s personal computer free of charge.
“It can also be copied to a USB stick, which can be used on any PC at school or university, with no installation required,” he said.
Mr Teh and Mr Curran have drawn on their own experience as blind computer users to develop a product which has some unique features. For example, as the mouse moves up and down the screen, a sound becomes higher and lower to let you know where the cursor is located.
NVDA has been translated into 27 languages, thanks to volunteer translators. To date, there have been over 50,000 downloads.
Mr Teh and Mr Curran have been working on the project since 2006. They worked on their product without any pay for two years. When Mozilla offered some funding in 2008, Mr Teh was able to quit his day job and work full-time developing NVDA.
【小題1】NVDA won an award in the program of the ABC’s New Inventors because it _____.

A．causes no harm to the environmentB．influences people’ s lives
C．is aiming at blind peopleD．is easy to use
【小題2】Why did James Teh and Michael Curran want their software to be free?
A．They got funding from Mozilla.
B．They belonged to a volunteer group.
C．They wanted to help the blind.
D．They wanted people to give up “screen reader” software.
【小題3】What do we know about Teh and Curran?
A．They are studying at QUT.B．They are good at translating.
C．They know how the blind feel.D．They began to develop NVDA in 2008.

以下是旅游景點(diǎn)的信息：

A. Agra Fort

Near the gardens of the Taj Mahal stands the important 16th-century Mughal monument known as the Red Fort of Agra. This powerful fortress of red sandstone encompasses, within its 2.5-km-long enclosure walls, the imperial city of the Mughal rulers. It comprises many fairy-tale palaces, such as the Jahangir Palace and the Khas Mahal, built by Shah Jahan; audience halls, such as the Diwan-i-Khas; and two very beautiful mosques.

 

B. Taj Mahal

Taj Mahal is regarded as one of the eight wonders of the world, and some Western historians have noted that its architectural beauty has never been surpassed. The Taj is the most beautiful monument built by the Mughals, the Muslim rulers of India. Taj Mahal is built entirely of white marble. It was constructed over a period of twenty-two years, employing twenty thousand workers. It was completed in 1648 C.E. at a cost of 32 Million Rupees.

C. Keoladeo National Park

This former duck-hunting reserve of the Maharajas is one of the major wintering areas for large numbers of aquatic birds from Afghanistan, Turkmenistan, China and Siberia. Some 364 species of birds, including the rare Siberian crane, have been recorded in the park.

D. Humayun's Tomb, Delhi

This tomb, built in 1570, is of particular cultural significance as it was the first garden-tomb on the Indian subcontinent. It inspired several major architectural innovations, culminating in the construction of the Taj Mahal. The gardens also contain the red-and-white sandstone and black-and-yellow marble tomb of Humayun’s wife and the tomb of Humayun’s barber.

E. Grand Canyon National Park

The Grand Canyon is perhaps the most awesome sight in the United States--and one of the wonders of the world. Much of the park's beauty is related to its geology and ecology. Schmidt explores the shape of the land, its plants and animals, and its human history. A fascinating book that everyone visiting the Grand Canyon should read. The Skywalk at Grand Canyon West is really exciting.

F.Sundarbans National Park

The Sundarbans covers 10,000 sq. km of land and water (more than half of it in India, the rest in Bangladesh) in the Ganges delta. It contains the world's largest area of mangrove forests. A number of rare or endangered species live in the park, including tigers, aquatic mammals, birds and reptiles.
