Wheelchairs had never seemed like scary objects to me before I had to sit in one. A tight knot grabbed hold in my stomach when I first took a close look at what was to be my only means of getting around for several hours. I was stuck by the irrational thought, "once I am in this wheelchair, the handicap might become real, and I might never walk again." This thought, as ridiculous as it was, frightened me so much that I needed a large dose of courage just to sit down.
After I overcame my fear of the wheelchair, I had to learn how to cope with it. I wiggled around to find a comfortable position and thought I might even enjoy being pampered and wheeled around. I glanced over my shoulder to see who would be pushing me. It was only then that I realized I would have to navigate the contraption all by myself! My palms reddened and started to sting as I tugged at the heavy metal wheels. I could not seem to keep the chair on an even course or point the wheels in direction I wanted to go. I kept bumping into doors, pews, and other people. I felt as though everyone was staring at me and commenting on my clumsiness.
When the service started, more problems cropped up to frustrate me even further. Every time the congregation stood up, my view was blocked. I could not see the minister, the choir, or the altar. Also, as the church's aisles were narrow, I seemed to be in the way no matter where I parked myself. For instance, the ushers had to step around me in order to pass the collection plate. This Shade me feel like a nuisance. Thanks to a new building program, our church will soon have the wide aisles and well-spaced pews that will make life easier for the handicapped. Finally, if people stopped to talk to me, I had to strain my neck to look up at them. This made me feel like a little child being talked down to and added to my sense of helplessness.
My few hours as a disabled person left a deep impression on me. Now, I no longer feel resentment at large tax expenditures for ramp equipped buses, and I wouldn't dream of parking my car in a space marked "Handicapped Only." Although my close encounter with a handicap was short-lived, I can now understand the challenges, both physical and emotional, that wheelchair-bound people must over come.
To "adopt a handicap" the writer chose to ______.
A.be confined to wheelchairs
B.stuff cotton in his ears
C.hobble around on crutches
D.wear blindfolds

Construction of the bridge, including design and cornerstone, began in March 1991 and was completed in July 2000. Today, it is the longest stone-stayed road and rail bridge in the world. At approximately 10 miles (16 kilometers), including the tunnel, it is an engineering and architectural marvel. But as time has proven, the bridge is a cultural and economic boon as well. The sleek span of concrete whose design typifies Scandinavian minimalism has contributed greatly to the development of the Oresund region: the eastern part of Denmark, including Copenhagen, and the southwestern part of Sweden, including Malm?and Lund.
The level of commuting between Malm?and Copenhagen has quadrupled since the opening of the bridge in 2000, and the number of Danes moving to the south of Sweden has increased sixfold. The Oresund region has become a cultural and economic powerhouse, considered a model region by the European Union. Work on the bridge began in 1995, and was undertaken by a team of international consulting and construction companies.
From the beginning, construction of the bridge complied with some of the world? s toughest environmental regulations, as well as many advanced design and construction details. The Mexico-based CEMEX, one of the world? s largest producers of Cement and ready-mix concrete, was awarded a contract to deliver tons of high-quality cement to help build the main part of the bridge, the two approach bridges and the tunnel.
When it opened in July 2000, the Oresund Bridge consisted of a 3.5-kilometer immersed tunnel, the largest of its kind in the world, a 4-kilometer long artificial island (made from mud dug out from the bottom of strait to make space for the tunnel) and a 7.8-kilometer cable-stayed bridge, the world? s longest bridge including both a highway and a railroad.
Though just half of the total construction, the actual bridge span, is visible above water, the overall architecture was designed to please the eye from both the Danish and Swedish sides of the strait.
The four 204-meter (670 feet) tall pillars carrying the bridge have a simple Scandinavian design. To drivers and passengers crossing the bridge, the pillars provide a visual, as well as actual, impression of stability and calm.
The two-level structure is made of steel and concrete. Along tile two approach bridges, tracks are placed in concrete troughs that turn into steel decks on the bridge. The bridge? s upper deck carries cars and trucks, while the lower deck accommodates the railroad. The four pillars are grounded in giant cement boxes placed at the bottom of the strait, about 18 meters below sea level.
Last year, an average of 13,600 vehicles and 17,000 passengers crossed the bridge everyday, and traffic continues to increase by 10-20 percent every year.
Throughout the construction process, the Danish and Swedish environmental agencies have surveyed but found no changes in the wildlife, birds, fish and vegetation surrounding the bridge. In addition, the chemicals used in construction and the percentage of waste materials have been kept to a minimum, as required by both Danish and Swedish laws.
In 2003, the Oresund Bridge won the IABSE (International Association for Bridge and Structural Engineering) Outstanding Structural Award for its innovative design, planning and construction management, as well as its strict compliance with the time schedule, budget and environmental requirements.

Even ancient Egypt's mighty pyramid builders were powerless in the face of the famine that helped bring down their civilisation around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometres to the south was ultimately to blame -- and the same or worse could happen today.
The ancient Egyptians depended on the Nile's annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods.
Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablise the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile4.
The Blue Nile mud has a different isotope signature from that of the White Nile. So by analysing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.
Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river' would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt's Old Kingdom.
The weakened waters would have been catastrophic for the Egyptians. "Changes that affect food supply don't have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doherty Earth Observatory in New York.
Similar events today could be even more devastating, says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D.C. "Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically."
Why does the author mention "pyramid builders"?
A.Because they once worked miracles.
B.Because they were well-built.
C.Because they were actually very weak.
D.Because even they were unable to rescue their civilisation.
