閱讀簡答

  I had always planned to take a tour of Yosemite, and I finally fulfilled my dream last December.I cannot help but express how much I enjoyed my tour of Yosemite.

  As the best-known scenic spot, Yosemite National Park is actually a natural wonder.The park is located in the middle of the Nevada mountain range.It has huge rocks, great waterfalls and fantastic valleys.

  I really need to thank my tour guide, Tony.He was very helpful and he told me a lot of interesting facts about the scenic spots we saw.As I couldn't drive, the tour guide was also my driver.He picked me up at 8 o'clock in the morning.He was a professional and experienced tour guide, so he tried everything to make sure that I had an interesting and relaxing tour.As he was driving, he kept on telling me about the wildlife and the unique scenery in this surprising land.

  Bridalveil Fall was our first stop.The best time to see it is in summer, but I didn't go there in the hot season, so the waterfall was not as good as it could have been.I still took a photo of myself standing in front of this terrific waterfall before leaving for my next stop.When I first saw El Capitan, the largest standing sandstone structure in the world, I knew why it was called “El Capitan”.The huge structure dwarfed(使矮小)everything around it.Though I was used to seeing skyscrapers, nothing had prepared me for this.

  I felt so happy and excited after I came back from Yosemite.I haven't had this feeling for a very long time.Happiness usually comes when we do activities that accomplish something, which is a deep feeling of joy that often lasts a long time.So I decided to go out for a trip constantly to make myself happy and relaxed.

1.What is Yosemite National Park famous for?(No more than 7 words)

2.Why did the author think Tony was a professional and experienced guide?(No more than 11 words)

3.Why was the author shocked when he first saw El Capitan?(No more than 7 words)

4.According to the passage, what made the author so excited?(No more than 7 words)

C
Cancun is a seaside town in Mexico, where most tourists come here to enjoy the beach, water sports and night life. In fact, it is so modern and Americanized that you might think you were in southern California or Florida.
But just a short two-hour hike from the town lie the ruins of the city of Chichen-Itza, one of the capitals of the lost Maya(瑪雅)civilization. The center of the ruins of this city is the pyramid of El Castillo. The ancient Mayan religious people climbed this pyramid during festival to honor the Sun god. Tourists today climb it to view the architectural achievements of Chichen-Itza and to prove their fearlessness of heights and steep (陡峭的)climbs. There is a sign in Spanish, admonishing visitors “It’s dangerous to go up.” I gladly ignored it and started my climb.
The climbing was tough. The steps were higher than one might normally take., but the climb was not fearful at all. From the top of the pyramid, I had a wonderful view of the ruins of this Mayan city. What was most striking to me was that just beyond the ruins of splendid structures, gardens, temples and what looks like a modern sports stadium, you could only see forests for miles and miles. It was almost as if some race had mysteriously come out of nowhere, built it up and then suddenly disappeared from the planet, leaving only stones in its space.
The only remains on the top of the pyramid were the Temple of Kukulcan. During the festivals to worship the Sun god, only the high ranks would have the right to enter this temple.
After shooting a few pictures, I realized it was time to go down. Only then did I discover that what people fear about the climb is not the trip going up, but the way going down. I saw a few brave souls who were walking down as if they were in their own house. Looking down at the steepness of the pyramid, I desperately feared this great height. My first desire was to joke with a few people, “Where is the elevator(電梯)?” I figured that a civilization that was this advanced would have had the foresight(預見) to construct an elevator. Lacking such modern equipment, I had to use the chain provided by the Mexican tourist authorities and climb down on all fours.
My climb was complete eventually. I quickly got on the bus back to my comfortable hotel. Leaving the ruined city, I was still wondering what possibly happened long ago. But a few hours later, I was back in the modern world drinking cocktails on the beach, bathing in the sunshine before boarding the plane and waiting for my trip back home to the US, where all the modern things such as elevators are available!
57. Why did the writer pay a visit to the ruined city of Chichen-Itza?
A. He wanted to climb the pyramid of EL Castillo and know about the Mayan civilization.
B. He would got to the Temple of Kukulcan to attend a religious festival to honor the Sun god.
C. He thought the city of Chichen-Itza was quite different from the modern town of Cancun.
D. He was attracted by the ruined ancient buildings there and wanted to take some photos.
58. The underlined word “admonishing” in Paragraph 2 probably means “___________”.
A. urging          B. forcing          C. warning         D. frightening
59. Which of the following best shows climbing the pyramid of EL Castillo is a difficult task?
A. The steps are very high and it is much more scaring to climb to the top.
B. The climbing calls for courage and patience, and also takes a long time.
C. When tourist climb up to the top, there is no elevator to take them down.
D. The pyramid is high and steep, and climbing down is much more fearful.
60. From the last paragraph, we can infer that the writer ______________.
A. had a bad impression of the visit and decided to leave as soon as possible.
B. thought modernization could offer people comforts and conveniences.
C. got tired of the modern life and tried a different one in his own way.
D. enjoyed himself in the climb though it was very tiring and dangerous.

科目:高中英語 來源:2011-2012學年山西省山大附中高一5月月考英語試卷(帶解析) 題型:閱讀理解

There are two ways to save money traveling. The first way is to get the best deals on the specific things you want. There is a limitation to this type of approach (途徑,方法) though. If you find the lowest price on the best hotel in Honolulu at the height of the season, you will save money, but still have a very expensive vacation. Trying to get exactly what you want will generally be an expensive proposition, in travel and in life.
The other approach is to be a true opportunist. This will be difficult for some of you, and entirely unacceptable to others. Nonetheless (盡管如此),the travelers who get to travel the most, go to the widest variety of places, learn the most and do the most, are the opportunists. This will be true until you are so wealthy that you have no monetary (貨幣的;錢的)limits.
The first time I went to Ecuador, I went there because it was cheap. If it wasn’t, I would have had a great time—somewhere else. The trip lasted a month, and cost $1045, which included airfare and even the $130 fee for a guide to take me to the top or glacier (冰川) covered Mount Chimborazo.
I cut the cost by taking a bus from my home in Michigan to Miami, and back again when I returned from Ecuador. The round-trip ticket cost $158. The round-trip flight to Quito from Miami was only $256, because it was a courier (信使,通訊員) flight, which meant I signed for some luggage(car parts), and  could only take carry-on luggage.
Never did I feel deprived, or bored. I had a great time, eating wherever it was cheap and clean, doing all sorts of inexpensive, but interesting things, and traveling across the country to climb Chimborazo. I also met and fell in love with my wife Ana.
Being an opportunist means you’ll have just as much variety, and probably almost everything you want—eventually. You just have to stop trying to get exactly what you want exactly when you want it. If the guide that took me up Chimborazo hadn’t dropped his price from $200 to $130, I would have spent $2 for a bus and gone hiking on EI Altar, another great Andean mountain. That would have left me with enough money for several other minor adventures.
【小題1】The underlined phrase “the best deals” in the first paragraph probably refers to ______.

A.the best serviceB. the lowest price
C.the cheapest goodsD. the best approaches
【小題2】The return tickets from his hometown to Quito cost the author ______.
A.$128B. $256C. $207D. $414
【小題3】The last paragraph was to tell us how to ______.
A.save money for minor adventures
B.cut down traveling costs.
C.deal with different situations
D.become opportunist travelers
【小題4】It’s suggested that the author _____.
A.went hiking on El Altar
B.traveled with his wife in Ecuador
C.is an opportunist traveler
D.likes traveling around the world
【小題5】Which of the following can serve as the best title of the passage?
A.Cheap Travel SecretsB. Travel Secrets
C.A Travel OpportunistD. Travel Tips

It was early morning. Peter Corbett helped Mark Wellman out of his wheelchair and onto the ground. They stood before El Capitan, a huge mass of rock almost three-quarters of a mile high in California's beautiful Yosemite Valley. It had been Mark's dream to climb El Capitan for as long as he could remember. But how could a person without the use of his legs hope to try to climb it?

Mark knew he couldn't finish the climb alone, but his friend Peter, an expert rock climber, would be there to lend a helping hand. He and Mark thought that it would take seven days to reach the top.

Peter climbed about 100 feet up and hammered a piton (巖釘) into the rock. Fastening one end of a 165-foot rope to the piton, he let one end of the rope fall down. Mark caught the rope and fastened it to his belt with a special instrument. This instrument would allow Mark to move upward, but would prevent him from falling even as much as a single inch. He next reached above his head and fastened a T-shaped bar to the rope, using the same kind of instrument.

Mark took a deep breath, pushed the T-bar up almost as far as his arms could reach, and began the first of the 7,000 pull-ups needed to reach the top. High above, Peter let out a cheer. “You're on your way.”

Seven years before, at the age of twenty-one, he had fallen while mountain climbing, injuring his backbone. The fall cost him the use of his legs, but he never lost his love of adventure or his joyful spirit.

For the first four days the two men progressed steadily upward without incident. But on the fifth day an unbearably hot wind began to blow, and as time went by, it became stronger and stronger, causing Mark to sway (搖擺) violently on his rope. But Mark kept on determinedly pushing up the T-bar and pulling himself up. In spite of that, he had to admit that he felt a lot better when the wind finally died down and his body touched solid rock again.

It took them one day more than they had expected, but on July 26 at 1:45 in the afternoon, the crowd of people waiting on the top went wild with joy as the two heads appeared. Mark Wellman had shown that if you set your heart and mind on a goal, no wall is too high, no dream impossible.

1.What had Mark Wellman long desired to do?

A.To finish one of the most difficult rock climbs in the world.

B.To be the first to climb El Capitan.

C.To climb the highest mountain in California.

D.To help his friend Peter climb El Capitan.

2.How did Mark climb the mountain?

A.He fastened the rope to his wheelchair.

B.He hammered in pitons so that he had something to hold on to.

C.He held on to the T-bar and Peter pulled him up.

D.He pulled himself up using a T-bar and special equipment.

3.What was the worst problem Mark had during the climb?

A.He struck against the rock and hurt his arms.

B.A strong wind blew him away from the rock.

C.He kept falling several inches.

D.While swaying in space, he became terrified.

4.How did Mark react to difficulties during the climb?

A.He admitted that he was frightened.

B.He often worried about his friend's condition.

C.He was able to remain clam and determined.

D.He was joking to cheer himself up.
