The World&39;s Longest Bridge

Rumor &39;has it that a legendary six-headed monster lurks in the deep waters of the Tyrrhenian Sea between Italy and the island of Sicily.(46) When completed in 2010, the world&39;s longest bridge will weigh nearly 300,000 tons -- equivalent to the iceberg that sank the Titanic -- and stretch 5 kilometers long. "That&39;s nearly 50 percent longer than any other bridge ever built," says structural engineer Shane Rixon.

(47)They&39;re suspension bridges, massive structures, built to span vast water channels or gorges. A suspension bridge needs just two towers to shoulder the structure&39;s mammoth weight, thanks to hefty supporting cables slung between the towers and anchored firmly in deep pools of cement at each end of the bridge. The Messina Strait Bridge will have two 54,100-ton towers, which will support most of the bridge&39;s load. The beefy cables of the bridge, each 1.2 meter in diameter, will hold up the longest and widest bridge deck ever built.

When construction begins on the Messina Strait Bridge in 2005, the first job will be to erect two 370 meter-tall steel towers.(48)Getting these cables up will be something. It&39;s not just their length -- totally 5.3 kilometers -- but their weight.(49).

After lowering vertical "suspender" cables from the main cables, builders will erect a 60- meter-wide 54,630-ton steel roadway, or deck -- wide enough to accommodate 12 lanes of traffic. The deck&39;s weight will pull down on the cables with a force of 70,500 tons. In return, the cables yank up against their firmly rooted anchors with a force of 159,000 tons -- equivalent to the weight of about 100,000 cars. Those anchors are essential.(50).

A Some environmentalists are against the project on biological grounds.

B What do the world&39;s longest bridges have in common？

C If true, one day you might spy the beast while zipping (呼啸而过) across the Messina Strait Bridge.

D They&39;re what will keep the bridge from going anywhere.

E The second job will be to pull two sets of steel cables across the strait, each set being a bundle of 44,352 individual steel wires.

F They will tip up the scales at 166,500 tons -- more than half the bridge&39;s total mass.

Some Unusual Celebrations

Some holidays are well-known all around the world. Among them are New Year&39;s Eve celebra-tions. Also common are days in honor of love and friendship,like Valentine&39;s Day. Each country has itsown special holidays, too, often to mark important events in its history. Schools, banks, and govern-ment offices all close on days like these. (46)A few of them are really very strange.

Of course. they are not strange to the people who celebrate them. Perhaps that is because the cele-brations have long traditions. Consider April Fool&39;s Day,for example. No one knows when or why itbegan. Today it is celebrated in many countries-France, England, and Australia,among others. On thisday, people play practical jokes. _(47)The ones who laugh are the ones playing the jokes. Thepeople they fool often get angry. Does celebrating this day make sense to you？

Dyngus Day in Poland seems strange, too. On this day,it is traditional for boys to pour water overthe heads of girls. Here is the strangest part : They do it to girls they like.

Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is cel-ebrated in Bunol, Spain. Every year,in Jate August, big trucks carry more than 200, 000 pounds of to-matoes into this little town. (48)For two hours, people in the streets throw tomatoes at eachother. Everyone ends up red from head to toe.

August 10 marks the start of the Puck Fair,an Irish festival with a very unusual tradition. Peoplefrom the town of Killorglin go up into the mountains and catch a wild goat. (49)

There are also some celebrations that are really strange. In the United States, sometimes one per-son gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public SleepingDay？ That one is on February 28 It may seem strange, but it sounds like more fun than the one onFebruary (50)

Do you like the idea of inventing a new holiday？ If you do,then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day

？？A.Some of the days people celebrate, however,are less serious

B.That is supposed to be Toothache Day

C.Some people have fun imagining new holidays

Soot and Snow: a Hot Combination

1 New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow. According to a computer simulation, black soot may be responsible for 25 percent of observed global warming over the past century.

2 Soot in the higher latitudes of the Earth, where ice is more common, absorbs more of the sun&39;s energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while lighter colored ice reflects sunlight.

3 Soot in areas with snow and ice may play an important role in climate change. Also, if snow and ice covered areas begin melting, the warming effect increases, as the soot becomes more concentrated on the snow surface. "This provides a positive feedback, as glaciers and ice sheets melt, they tend to get even dirtier," said Dr. James Hansen, a researcher at NASA&39;s Goddard Institute for Space Studies, New York.

4 Hansen found soot&39;s effect on snow albedo (solar energy reflected back to space), which may be contributing m trends toward early springs in the Northern Hemisphere, such as thinning Arctic sea ice, melting glaciers and permafrost. Soot also is believed to play a role in changes in the atmosphere above the oceans and land.

5 "Black carbon reduces the amount of energy reflected by snow back into space, thus heating the snow surface more than if there were no black carbon," Hansen said. Soot&39;s increased absorption of solar energy is especially effective in warming the world&39;s climate. "This forcing is unusually effective, causing twice as much global warming as a carbon-dioxide forcing of the same magnitude," Hansen noted.

6 Hansen cautioned, although the role of soot in altering global climate is substantial, it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century, Such gases are expected to be the largest climate forcing for the rest of this century.

7 The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes. These observations were consistent with the researchers&39; climate model simulations, which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight.

Paragraph 3 ______

New Foods and the New World

In the last 500 years, nothing about people--not their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians. The Spanish introduced it to the rest of the world during the 1500&39;s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.

The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine" of 1845--1846, and thou-sands more Were forced to emigrate to America.

There are many other that that have traveled from South America to the Old World.. But some others went in the opposite direction. Brazil is now the world&39;s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400&39;s.

According to an Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the "wide-awake" feeling that one-third of the world&39;s population now starts the day with.

According to the passage， which of the following has changed the most in the last 500 years？ 查看材料

A.Food

Tony Huesman, a heart transplant recipient （接受者) who lived a record 31 years with a sin

Tony Huesman, a heart transplant recipient (接受者) who lived a record 31 years with a single donated organ has died at age 51 of leukemia (白血病), but his heart still going strong. "He had leukemia," his widow Carol Huesman said, "His heart—believe it or not—held out. His heart never gave up until the end, when it had to."

Huesman got a heart transplant in 1978 at Stanford University. That was just 11 years after the world&39;s first heart transplant was performed in South Africa. At his death, Huesman was listed as the world&39;s longest survivor of a single transplanted heart both by Stanford and the Richmond, Virginia-based United Network for Organ Sharing.

"I&39;m a living proof of a person who can go through a life-threatening illness, have the operation and return to a productive life," Huesman told the Dayton Daily News in 2006.

Huesman worked as marketing director at a sporting-goods store. He was found to have serious heart disease while in high school. His heart, attacked by a pneumonia (肺炎) virus, was almost four times its normal size from trying to pump blood with weakened muscles.

Huesman&39;s sister, Linda Huesman Lamb, also was stricken with the same problem and received a heart transplant in 1983. The two were the nation&39;s first brother and sister heart transplant recipients. She died in 1991 at age 29.

Huesman founded the Huesman Heart Foundation in Dayton, which seeks to reduce heart disease by educating children and offers a nursing scholarship in honor of his sister.

Tony Huesman died from ____________.

A.heart failure

B.heart transplant

C.pneumonia

D.non-heart-related disease

Rivers are one of our most important natural resources （资源). Many of the world&39;s grea

Rivers are one of our most important natural resources (资源). Many of the world&39;s great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.

Since the beginning of the history, people have used rivers for transportation(运输). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.

Besides transportation, rivers give food, water to drink, water for crops(庄稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大坝) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.

However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化学物质) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.

The greatest river for navigation is ___________.

A.the Amazon

B.the Nile

C.the Mekong

D.the Mississippi

From a dam, people can use the water for ___________.A.keeping the rivers clean

B.only making electricity

C.washing clothes

D.irrigation and making electricity

The water in the river is polluted because of _____________.A.people's drinking water too much

B.people's swimming in the river too much

C.chemicals and other materials

D.people's building a dam across a river

The best title of the passage is ___________.A.Rivers in Cities

B.The importance of Rivers

C.Transportation

D.Natural Resources

Early in the age of affluence（富裕）that followed World War II, an American retailing analy
st named Victor Lebow proclaimed, "Our enormously productive economy... demands that we make consumption our way of life, that we convert the buying and use of goods into rituals, that we seek our spiritual satisfaction, our ego satisfaction, in consumption...We need things consumed, burned up, worn out, replaced and discarded at an ever increasing rate."

Americans have responded to Lebow&39;s call, and much of the world has followed.

Consumption has become a central pillar of life in industrial lands and is even embedded in social values.

Opinion surveys in the world&39;s two largest economies-Japan and the United States-show consumerist definitions of success becoming ever more prevalent.

Overconsumption by the world&39;s fortunate is an environmental problem unmatched in severity by anything but perhaps population growth. Their surging exploitation of resources threatens to exhaust or unalterably spoil forests, soils, water, air and climate.

Ironically, high consumption may by a mixed blessing in human terms, too.

The time-honored values of integrity of character, good work, friendship, family and community have often been sacrificed in the rush to riches.

Thus many in the industrial lands have a sense that their world, of plenty is somehow hollow-that, misled by a consumerist culture, they have been fruitlessly attempting to satisfy what are essentially social. psychological and spiritual needs with material things.

Of course,. the opposite of overconsumption-poverty-is no solution to either environmental or human problems. It is infinitely worse for people and bad for the natural world too. Dispossessed(被剥夺得一无所有的) peasants slash-and-burn their way into the rain forests of Latin American, and hungry nomads (游牧民族) turn their herds out onto fragile African grassland, reducing it co desert.

If environmental destruction results when people have either too little or too much, we arc left to wonder how much is enough. What level of consumption can the earth support？ When does having more cease to add noticeably to human satisfaction？
