The Norwegian government is doing its best to keep the oil industry under control. A new l
aw limits exploration to an area south of the southern end of the long coastline, production limits have been laid down, and oil companies have not been allowed to employ more than a limited number of foreign workers. But the oil industry has a way of getting over such problems, and few people

believe that the government will be able to hold things back for long.

Ever since the war, the government has been carrying out a program of development in the area north of the Arctic Circle. During the past few years this program has had a great deal of success. Tromso has been built up into a local capital with a university, a large hospital and a healthy industry . But the oil industry has already started to draw people south, and within a few years the whole northern policy could be in ruins.

The effects of the oil industry would not be limited to the north, however. With nearly 100 per cent employment, everyone can see a situation developing in which the service industries and the tourist industry will lose most of their workers to the oil industry. Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.

The Norwegian government would prefer the oil industry to ______

A.provide more jobs for foreign workers

B.slow down the rate of its development

C.sell the oil it is producing abroad

D.develop more quickly than at present

Scientists Weigh Options for Rebuilding New OrleansAs experts ponder how best to rebuild t

Scientists Weigh Options for Rebuilding New Orleans

As experts ponder how best to rebuild the devastated(毁坏) city, one question is whether to wall off—or work with--the water.

Even before the death toll from Hurricane Katrina is tallied, scientists are cautiously beginning to discuss the future of New Orleans. Few seem to doubt that this vital heart of U.S. commerce and culture will be restored, but exactly how to rebuild the city and its defenses to avoid a repeat catastrophe is an open question. Plans for improving its levees and restoring the barrier of wetlands around New Orleans have been on the table since 1998, but federal dollars needed to implement them never arrived. After the tragedy, that's bound to change, says John Day, an ecologist at Louisiana State University (LSU) in Baton Rouge. And if there is an upside to the disaster, he says, it's that "now we've got a clean slate to start from."

Many are looking for guidance to the Netherlands, a country that, just like bowl-shaped New Orleans, sits mostly below sea level, keeping the water at bay with a construction of amazing scale and complexity. Others, pointing to Venice's long-standing adaptations, say it's best to let water flow through the city, depositing sediment to offset geologic subsidence---a model that would require a radical rethinking of architecture, Another idea is to let nature help by restoring the wetland buffers between sea and city.

But before the options can be weighed, several unknowns will have to be addressed. One in precisely how the current defenses failed. To answer that, LSU coastal scientists Paul Kemp and Hassan Mashriqui are picking their way through the destroyed city and surrounding region, reconstructing the size of water surges by measuring telltale marks left on the sides of buildings and highway structures. They are feeding these data into a simulation of the wind and water around New Orleans during its ordeal.

"We can't say fur sure until this job is done," says Day, "but the emerging picture is exactly what we've predicted for years." Namely, several canals--including the MRGO, which was built to speed shipping in the 1960s--have the combined effect of funneling surges from the Gulf of Mexico right to the city's eastern levees and the lake system to the north. Those surges are to blame for the flooding. "One of the first things we'll see done is the complete backfilling of the MRGO canal," predicts Day, "which could take a couple of years."

The levees, which have been provisionally repaired, wilt be shored up further in the months to come, although their long-term fate is unclear. Better levees would probably have prevented most of the flooding in the city center. To provide further protection, a mobile dam system, much like a storm surge barrier in the Netherlands, could be used to close off the mouth of Lake Pontchartrain. But most experts agree that these are short-term fixes.

The basic problem for New Orleans and the Louisiana coastline is that the entire Mississippi River delta is subsiding and eroding, plunging the city deeper below sea level and removing a thick cushion of wetlands that once buffered the coastline from wind and waves. Part of the subsidence is geologic and unavoidable, but the rest stems from the levees that have hemmed in the Mississippi all the way to its mouth for nearly a century to prevent floods and facilitate shipping. As a result, river sediment is no longer spread across the delta but dumped into the Gulf of Mexico. Without a constant stream of fresh sediment, the barrier islands and marshes are disappearing rapidly, with a quarter, roughly the size of Rhode Island, already gone.

After years of political wrangling, a broad group pulled together by the Louisiana government in 1998 proposed a massive $14 billion plan to save the Louisiana coasts, called Coast 2050 (now modified i

Mt. Desert IslandThe coast of the State of Maine is one of the most irregular in the world

Mt. Desert Island

The coast of the State of Maine is one of the most irregular in the world. A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is . the result of what is called a drowned coastline. ______【46】. At that time, the whole area that is now Maine was part of a mountain range that lowered above the sea. As the glacier (冰川) descended, however, it expended enormous force on those mountains, and they sank into the sea.

As the mountains sank, ocean water charged over the lowest arts of the remaining land, forming a series of twisting inlets and lagoons (咸水湖) . The highest parts of the former mountain range, nearest the shore, remained as islands. ______【47】Marine fossils found here were 225 feet above sea level, indicating the level of the shoreline prior to the glacier.

The 2, 500-mile-long rocky coastline of Maine keeps watch over nearly two thousand islands. Many of these islands are tiny and uninhabited, but many are home to thriving communities. Mt. Desert Island is one of the largest, most beautiful of the Maine coast islands. Measuring 16 miles by 12 miles, Mt. Desert Island was essentially formed as two distinct islands. ______【48】.

For years, Mt. Desert Island, particularly its major settlement, Bar Harbor, afforded summer homes for the wealthy. Recently though, Bar Harbor has become a rapidly growing arts community as well. But the best part of the island is the unspoiled forest land known as Acadia National Park. Because the island sits on the boundary line between the temperate (温带) and sub-Arctic zones, the island supports the plants and animals of both zones as well as beach, inland , and alpine (高山 的) plants. ______【49】The establishment of Acadia National Park in 1916 means that this natural reserve will be perpetually available to all people, not just the wealthy. Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping, cycling, and boating. Or they may choose to spend time at the archeological museum, learning about the Stone Age inhabitants of the island.

The best view on Mt. Desert Island is from the top of Cadillac Mountain. ______【50】. From the summit, you can gaze back toward the mainland or out over the Atlantic Ocean and contemplate the beauty created by a retreating glacier.

A. It also lies in a major bird migration lane and is a resting spot for many birds.

B. Mt. Desert Island is one of the most famous of all of the islands left behind by the glacier.

C. The wealthy residences of Mt. Desert Island selfishly keep it to themselves.

D. The term comes from the activity of the Ice Age.

E. This mountain rises 1, 532 feet, making it the highest mountain on the Atlantic seashore.

F. It is split almost in half by Somes Sound, a deep and narrow stretch of water seven miles long.
