A house of cards? Sounds unbelievable, doesn’t it? Not if the architect is 31-year-old Bryan Berg. He’s made a career out of building fantastic card houses, stadiums, capitols, castles — and the world’s tallest card tower. How does he do it?
Bryan’s structures are amazing because they are made entirely of perfectly balanced, freestanding playing cards. He never uses glue, tape, or anything else to hold the cards together. Nor does he fold the cards. He’s discovered another way to make a strong house of cards, using a trick from nature.
To make plants strong, nature builds them with cells that have tough walls. Rows and rows of these cells form a grid(格子) that helps leaves and stems keep their shape. Bees use the same kind of repeating pattern to create strong honeycombs, where they live and store honey. Bryan designs similar grids, using cards to create a repeating pattern of cells.
He begins with a single cell made by balancing four cards against one another to form a box. Then he repeats the cell over and over, expanding outward to form the grid, which makes a good foundation for a strong card structure. The larger the grid, the more weight it can carry. Sometimes Bryan uses several cards, instead of just one, to construct the cell walls, making the grid even stronger. The trick, he tells kids when he speaks in classrooms, is to place your cards as tightly together as possible when laying out your grid, making sure the cards are not leaning at all.
After building this solid base, Bryan lays cards across the top to make the floor for the next “story” of the building. He may add towers, columns, steeples, or domes. Using the principle of repeating cells, Bryan builds structures of amazing strength.
In the Cards
Not surprisingly, Bryan has always been interested in building things. Growing up on a “big, old farm” in rural Iowa, he had plenty of room to play. “We were in the middle of nowhere,” Bryan remembers, “with lots of space to do whatever we wanted. I was always making something, using things like sticks or bales of hay.”
Bryan’s grandfather taught him how to stack cards. Bryan’s two interests — building and card stacking — soon combined. But stacking in his family’s farmhouse was challenging. “Our old house had wood floors that weren’t all level,” he reports. “And they weren’t very firm. When people walked around, it was like ‘earthquake action.’ It was a challenge to build something that wouldn’t fall down immediately.”
Bryan constructed tower after tower; he went through a lot of trial and error before he built anything taller than himself. When he placed a few decks of cards on top of his grid, he discovered how strong it was. Bryan’s towers began to grow taller.
How Tall Is Too Tall?
Bryan’s first Guinness World Record for the world’s tallest card tower came in the spring of 1992, when he was in high school. Learning that the world record was 12 feet 10 inches, Bryan built a slim tower that topped out at 14 feet 6 inches. Done as a project for his geometry class, it took him 40 hours and 208 decks of cards. Since then he’s gone on to win world records for even taller buildings. His latest winner measured 25 feet 3.5 inches and used about 2,400 decks of cards. The building, which tapered to a high, narrow point, had 131 stories.
Why don’t these towers fall down? The key is in a good solid base, a repeating pattern of stories, and a tapering top. Bryan likes to point out how card buildings resemble real ones. They are built cell by cell, story by story. The separate parts make one strong whole. The heavier the building, the stronger and more stable it is. But the weight can’t all be at the top.
After spending so much time building something so cool, Bryan admits it’s sometimes painful to see his structures destroyed. But he compares his work to the building of a sandcastle or an ice sculpture.
“They wouldn’t be as special if they were permanent,” he points out. “My buildings are like snowdrifts, or clouds in the sky. They can’t last forever.

“Tell me again how you learned to ride a horse,” I would ask my father when I was a little girl in Denmark. I was no more than four years old—too little to learn to ride a horse by myself. But I liked to hear my father tell his story. And then he would begin.
“When I was a little boy, as little as you are now,” he would say, “I wanted to ride the horses. But I was too small to mount a horse. So I would slip into my father’s stables to be with the horses and admire them. Such big, powerful animals they were!
“The gentle workhorses stood quietly in their stalls, eating their hay. I would climb up the side of one of the stalls and slide over onto the horse’s back.
“Then I would hold its mane and imagine us running quickly over the grasslands, down to the shore, and even into the sea.
“When I grew tall enough to mount a horse,” he said, “my wish came true.”
“You swim with the horses now,” I said. “You even swim with Fiery. And he has spirit!”
Everybody knew about Fiery, the great black male horse with the fierce temper, and how he behaved when he first came to the stables. He raised itself on its back legs with the front legs in the air. He snorted and kicked. He rolled his eyes. And everyone was afraid of him. Everyone, except my father.
I wanted to hear more. “Now tell me how you made Fiery your friend,” I begged. This was my favorite story.
“Well, little Else,” my father went on, “I just talked to him. I talked as a friend. You must talk to a horse like Fiery.
“I’d say, ‘No, little horse. No, my friend. You can’t run free. You must learn to let me ride you.’
“And soon Fiery began to listen. He knew from my voice that I would be his friend.”
So Fiery let my father teach him to carry a rider. Then Fiery would take my father across the soft green grasslands or even into the lively waters of the northern sea. I loved to see Father riding Fiery without a saddle(马鞍) into the sea. There they swam, Father and Fiery, out in the cold, clear water.
Often I would watch them from the shore, holding tight to my mother’s hand. They swam so bravely. I was so proud of them!
Then Father and Fiery would come splashing out of the water and run along the shore toward us. They made a fine stop—just in time!
Fiery towered over us. He tossed his head and shook sea water from his shining black coat.
Father was laughing and patting Fiery’s neck.
And I was making a wish.
I wished that someday I could have a horse, too . . . but a smaller one!

Many of our favorite travel destinations are in danger of being changed badly by increased temperatures and rising seas. The following are some of the places that may be in danger and some that are already experiencing the effects of global warming.
The Everglades, Florida: Perhaps no region of the country is as unprotected to climate change as Florida. Even a slight increase in temperature and water level could devastate popular destinations like the Everglades, Miami Beach and the Keys.
Australia’s Great Barrier Reef: One of the most impressive natural habitats in the world, the Great Barrier Reef could be killed by increased water temperatures and the resulting coral bleaching (漂白法). Australia is particularly easily damaged by global warming because of its large number of fragile (脆弱的) ecosystems, uncertain water sources and a large group of people gathering on the coast.
Dalian, China: Fast-growing China, shown here during a heat wave last year, is opening about one coal factory every day this year. Along with the U.S., China is one of the world's leading contributors to the greenhouse gases , which can lead to the increase in the Earth's temperature.
Venice, Italy: No stranger to flooding, Venice has invested $4.5 billion in a floodgate system that is due to open in 2012. But the frequent changing ocean levels have made people question the floodgates' ability to hold out the rising waters.
London, England: Designed to protect London from storms and extremely high tides, the Thames Barrier was opened in 1984. Some analysts fear that rising oceans will create conditions beyond the capabilities the barrier was designed to meet.
The word “devastate” in paragraph 2 means “_____________”.

A．protect

B．destroy

C．swallow

D．enlarge

What can endanger Great Barrier Reef directly?

A．Fragile ecosystem

B．Uncertain water sources.

Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people － up to 3 percent of the population － sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families － hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.
What caused the happening mentioned in the passage during Amanda’s running?

A．She couldn’t breathe in enough air in the race.

B．She didn’t eat anything before the race.

C．She had been running all summer without a rest.

D．She neither drank enough water nor ate enough of the right kind of foods.

What can we infer from Paragraph 4?

A．There is no need to worry when sweating too much, even in cold weather.

B．Hyperhidrosis may have a bad effect on your health.

C．Doctors have discovered why people get hyperhidrosis.

D．Hyperhidrosis is a serious disease and no treatment can help.

The purpose of writing this passage is to____________.

A．tell teens the proper ways to take exercise in summer.

B．tell teens not to run in hot summer.

C．tell teens to pay attention to hyperhidrosis in the summer exercise

D．tell teens how to keep healthy.
