Probably you have seen photographs of the Grand Canyon,the great valley in the desert country of Arizona.But you must go there yourself to feel its true size and beauty.The Grand Canyon is one of the greatest natural wonders of the world.
The Colorado River formed the Grand Canyon over millions of years.Slowly,the river cut down through hard rocks.At the same time,the land was rising.Today,the canyon is one and a half kilometers deep and 446 kilometers long.The oldest rocks at the bottom of the canyon are more than one billion years old.The width varies from about 200 meters to 29 kilometers across.The rim or top of the canyon is about 2,300 meters above sea level on the South Rim,and about 3,000 meters on the other side,the North Rim.As a result,there are different kinds of plants and animals on opposite sides of the canyon.The South Rim is a dry desert country.The North Rim has tall forests.
The canyon looks different at different times of a day,and in different seasons and weather.At sunrise and sunset the black,gold,brown,and orange colours of the rocks are especially clear and bright.In winter,the canyon is partly covered with snow.
The view from the South Rim of the Grand Canyon is the best.Most visitors come to the South Rim and stay in campgrounds or hotels.Every point along the canyon’s edge offers a different view.
The North Rim of the Canyon is quieter.It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River.On the way,you go through Navajo Indian lands,and a colourful pink desert called “The Painted Desert”.
You can walk down into the Grand Canyon,or you can go down on the back of a mule.You can also take a boat trip down the Colorado River,and camp on the beaches at night.But whether you see the Grand Canyon from the top or the bottom,it will be an experience that you will never forget.

How the Grand Canyon (大峡谷) was created remains one of the geology’s greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead.
Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam (堤坝) bursts.
Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava(熔岩) from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood that furthered the down-cutting process and deepened the canyon.
Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest that the process has happened there, too, say many other researchers.
The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon.
The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was once warm and wet.
1.In the past, deep canyons were believed to have formed _______.
A. as a result of a sudden break of volcanoes
B. due to river flows over millions of years
C. owing to the burst of artificial dams
D. thanks to our ancestors’ creative work
2.According to the passage, which of the following statements is TURE?
A. Several volcanoes broke out on Mars directly creating grand canyons.
B. Several great lakes existed on the upper parts of the Colorado River.
C. People built high dams on the upper parts of the Colorado River.
D. The Colorado River crossed the Grand Canyon to form down-cutting.
3.From the last three paragraphs we learn that _______.
A. there are great lakes on Mars
B. there are active volcanoes on Mars
C. there might be cities on Mars
D. there might be life on Mars
4.The passage can be titled as _______.
A. Lakes on Earth and Mars
B. The Cause of Lake Formation
C. The Force of Dam Breaking
D. Canyons—Results of Flood Cutting

When it comes to cultural heritage protection, the Grand Canal of China is probably the world’s greatest project of its kind. The big inland waterway system in the north-eastern and central eastern plains passes through eight of the country’s present-day provinces.
The Canal runs from Beijing in the north to Zhejiang Province in the south. Constructed in sections from the 5th century BC onwards, it was designed as a means of communication in the 7th century AD. The Canal is the world’s greatest civil engineering project before the Industrial Revolution.
The Grand Canal reached a peak in the 13th century, providing an inland navigation(航行) network consisting of more than 2,000 kilometers of artificial waterways, linking five of the most important river basins in China, including the Yellow River and the Yangtze. It entered a bid as a UNESCO(联合国教科文组织) cultural heritage site in 2008.
The Grand Canal cultural square is located in Beijing’s Tongzhou district. Ever since the Yuan dynasty 800 years ago, the Tongzhou section of the Grand Canal has been the life blood of Beijing. Grain and building materials were all transported to meet the endless demands of the big cities. Even today, the Grand Canal plays a major role in the lives of its citizens.
"I grew up near the Grand Canal. In the past the waterway was a lot narrower, but now it’s nice and wide and bridges are built over it. I think if the bid for world heritage status succeeds, it will greatly make Tongzhou more famous in the world, especially with Tongzhou aiming to be a sub-center of the capital Beijing," a citizen said.
The result of the bid is set to be released next week, and no doubt it will certainly make it into the history books if the Canal is listed as a world heritage site.
1.It can be concluded from the passage that .
A. The bid’s result of the Canal will be announced soon
B. the Canal is the UNESCO’s newest world heritage site
C. the Canal is to connect Tongzhou with Zhejiang Province
D. the Canal will be a bid for a UNESCO cultural heritage site
2.The Grand Canal was in the most glorious time .
A. when it was aimed as a means of communication
B. when it crossed the Yellow River and the Yangtze
C. when it was born about six hundred years later
D. when it was designed as an artificial waterway
3.What can we infer by reading the passage?
A. Tongzhou used to be the capital of the Yuan dynasty.
B. Most citizens living in Tongzhou depend on the Canal.
C. Tongzhou will benefit if the Canal is made a heritage site.
D. Some citizens think the Canal not to be a cultural heritage item.
