Probably you have seen photos of the Grand Canyon（峡谷）, 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 rock. At the same time, the land was rising. Today the canyon is 1.5 kilometers and 445 kilometers long. The oldest rocks at the bottom of the canyon are more than 1 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. As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Rim is dry desert country. The North Rim has tall forests.
The canyon looks different at different times of day, and in different seasons and weather. At sunrise and sunset the red, gold, brown and orange colors 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 here 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 Navado Indian lands, and a colorful pink desert called “The Painted Desert”.
60. The best way to feel the true beauty of the Grand Canyon is to________.
A. see its photographs B. listen to the report about it
C. watch its introduction on TV D. go there yourself and visit it
61. The scene of the canyon is ________.
A. various depending on different time and places
B.almost the same
C.various depending on different time
D. various depending on different places
62. If you want to visit the North Rim from the South Rim, you________.
A．can go there in many directions B．won’t spend much time on the way
C．can visit The Painted Desert on the way D．needn’t go across any bridges
63. If you want to have a visit to the Grand Canyon, you’d better go to _______.
A. the North Rim B. the South Rim C. the bottom D. Navado Indian Lands

阅读快车系列答案Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.
Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it，whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further： mirror neurons not only appear to explain physical actions y they also tell us that there is a biological basis for the way we understand other people.
Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example ："The hand took hold of the ball" ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).
Any problems with mirror neurons may well result in problems with behavior. Much researeh suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.
Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互动）.Indeed, it may turn out to be the equivalent (相等物）for ncurosciencc of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does--well，perhaps you'll understand why.

Three—quarters of a million tourists flock to the white beaches every year，but this booming industry has come at a price．Poisonous smoke rising from open fires，rubbish made up of plastic bottles，packets…it’S a far cry from the white sands，clear waters and palm trees that we associate with the Maldives(马尔代夫)，the paradise island holiday destination set in the Indian Ocean．
of its 200 inhabited islands，which are spread across an area of"35，000 square miles，99 are good resorts(旅游胜地)．So many tourists come every year，more than double the local population．Of these，over l 00，000 travel from the U K．The capital，Mal6，is four times more densely populated than London．Given these facts，it’S hardly surprising that the Maldives has a waste disposal problem．
Y ears a90，when the tourists left，the government had to deal with a stream of rubbish．Their solution was to turn one of the islands into a dumping ground．Four miles west of Mal6 is the country’s dumping ground，Thilafushi．What you are seeing here is a view of the Maldives on which no honeymooners will ever clap eyes．Each visitor produces 3．5 kg of waste per day．The country dumps more than 330 tons of rubbish on the island every day．
Now，since many waste boats，fed up with waiting seven hours or more，directly offload their goods into the sea，the government of the Maldives has banned the dumping of waste on the island．S0，the waste boats ship the rubbish to India instead．
【小题1】What is the main cause of the waste disposal problem?
| A．The big local population． | B．Too many waste boats． |
| C．The large number of tourists． | D．Open fires on the islands． |
| A．it’s quite similar to | B．it’S a long distance from |
| C．it’s a loud shout from | D．it’S totally different from |
| A．It iS much more crowded in Mal6 than in London． |
| B．Another island will be used as a dumping ground． |
| C．No honeymooners are willing to visit the Maldives． |
| D．Waste on islands will be offloaded directly into the sea． |
| A．To attract more tourists to the Maldives． |
| B．To state the waste disposal problem in the Maldives． |
| C．To call on us to protect the environment． |
| D．To explain the causes of pollution in the Maldives． |
A few months ago as I wandered through my parents’ house, the same house I grew up in, I had a sudden, scary realization. When my parents bought the house, in 1982, they were only two years older than I am now. I tried to imagine myself in two years, ready to settle down and buy the house I’d still be living in almost 30 years later.
It seemed ridiculous. On a practical level, there’s no way I could afford to buy a house anytime soon. More importantly, I wouldn’t want to. I’m not sure where I’ll be living in two years, or what kind of job I’ll have. And I don’t think I’ll be ready to settle down and stay in one place.
So this is probably the generation gap that divides my friends and me from our parents. When our parents were our age, they’d gotten their education, chosen a career, and were starting to settle into responsible adult lives.
My friends and I – “Generation Y” – still aren’t sure what we want to do with our lives. Whatever we end up doing, we want to make sure we’re happy doing it. We’d rather take risks first, try out different jobs, and move from one city to another until we find our favorite place. We’d rather spend our money on travel than put it in a savings account.
This casual attitude toward responsibility has caused some critics to call my generation “arrogant”, “impatient”, and “overprotected”. Some of these complaints have a point. As children we were encouraged to succeed in school, but also to have fun. We grew up in a world full of technological innovation: cellphones, the Internet, instant messaging, and video games.
Our parents looked to rise vertically(垂直的)--starting at the bottom of the ladder and slowly making their way to the top, on the same track, often for the same company. That doesn’t apply to my generation.
Because of that, it may take us longer than our parents to arrive at responsible, stable adulthood. But that’s not necessarily a bad thing. In our desire to find satisfaction, we will work harder, strive for ways to keep life interesting, and gain a broader set of experiences and knowledge than our parents’ generation did.
