Oil Industry in Norway
The Norwegian Government is doing its best to keep the oil industry under control.A new law limits exploration to an area south of the southern end of the long coastline;production limits have been laid down(though these have already been raised);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.
As an Norwegian politician said last week:"We will soon be changed beyond all recognition."
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 percent employment,everyone can see a situation developing in which the service industries and the tourist industry will lose more of their workers to the oil industry.Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.
The real argument over oil is its threat to the Norwegian way of life.Farmers and fishermen do not make up most of the population,but they are an important part of it,because Norwegians see in them many of the qualities that they regard with pride as essentially Norwegian.And it is the farmers and the fishermen who are most critical of the oil industry because of the damage that it might cause to the countryside and to the sea.
In the south,one effect to the development of the oil industry might be________.
A.a large reduction on unemployment
B.a growth in the tourist industry
C.a reduction in the number of existing industries
D.the development of a number of service industries

Oil and Economy
Could the bad old days of economic decline be about to return?Since OPEC agreed to supplycuts in March,the price of crude oil has jumped to almost $26 a barrel,up from less than$10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shock,when prices quadrupled,and 1979一1980,when they also almost tripled.Both previous shocks resulted in double一digit inflation and global economic decline.So where are the headlines warning of gloom and doom this time?
The oil price was given another push up this week when Iraq suspended oil exports.Strengthening economic growth,at the same time as winter grips the northern hemisphere,could push the price higher still in the short term.
Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s.In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s.In Europe,taxes account for up to four-fifths of the retail price,so even quite big changes in the price of crude oil have a more muted effect on pump prices than in the past.
Rich economies are also less dependent on oil than they were,and so less sensitive to swings in the oil price.Energy conservation,a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption.Software,consultancy and mobile telephones use far less oil than steel or car production.For each dollar of GDP(in constant prices)rich economies now use nearly 50%less oil than in 1973.The OECD estimates in its latest Economic Outlook that,if oil prices averaged $22 a barrel for a full year,compared with $13 in 1998,this would increase the oil import bill in rich economies by only 0.25-0.S%of GDP. That is less than one-quarter of the income loss in 1974 or 1980.On the other hand,oil-importing emerging economies一to which heavy industry has shifted一have become more energy一intensive,and so could be more seriously squeezed.
One more reason not to lose sleep over the rise in oil prices is that,unlike the rises in the 1970s,it has not occurred against the background of general commodity-price inflation and global excess demand.A sizable portion of the world is only just emerging from economic decline.The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%,and in 1979 by almost 30%.
From the text we can see that the writer seems______.
A.optimistic
B.sensitive
C.gloomy
D.scared

Ants Have Big Impact on Environment as " Ecosystem Engineers"
Research by the University of Exeter has revealed that ants have a big impact on their local environment
as a result of their activity as"ecosystem engineers"and predators.The study,published in the Journal of
Animal Ecology,found that ants have two distinct effects on their local environment?
Firstly.throuah moving the soil by nest building activity and by collecting food they affect the level of
nutrients in the soil.This can indirectly impact the local populations of many animal groups,from decomposers
to species much higher up the food chain.
Secondly,they prey on a wide range of other animals,including larger prey which can be attacked by
vast numbers of ant workers.
Dirk Sanders,an author of the study from the university's Centre for Ecology and Conservation,said,
"Ants are very effective predators which thrive in huge numbers.They're also very territorial and very ag-
gressive,defending their resources and territory against other predators.All of this means they have a strong
influence on their surrounding area."
"In this research,we studied for the first time how big this impact is and the subtleties of it.What we
found is that despite being predators,their presence can also lead to an increase in density and diversity of
other animal groups.They genuinely play a key role in the local environment,having a big influence on the
grassland food web,"Sanders said.
The study,carried out in Germany,studied the impact of the presence of different combinations and den-
sities of black garden ants and common red ants,both of which can be found across Europe,including the
UK. It found that a low density of ants in an area increased the diversity and density of other animals in the
local area,particularly the density of herbivores and decomposers.At higher densities ants had no or the op-
posite effect,the predation counteracting the positive influence.
Dr Frank van Veen,another author on the study,said:"What we find is that the impact of ants on soil
nutrient levels has a positive effect on animal groups at low levels,but as the number of ants increases,their
predatory impacts have the bigger effect一thereby counteracting the positive influence via ecosystem
engineering.
Ants are important components of the ecosystem not only because they constitute a great part of the ani--
mal biomass but also because they act as ecosystem engineers.Ant biodiversity is incredibly high and these
organisms are highly responsive to human impact,which obviously reduces its richness.However,it is not
clear how such disturbance damages the maintenance of ant services to the ecosystem.Ants are important in
below ground processes through the alteration of the physical and chemical environment and through their
effects on plants,microorganisms,and other soil organisms.
As predators,ants_________.
A.prey on small as well as large animals
B.collect nutritious food from the soil
C.collect food as decomposers
D.prey on species much higher up the food chain
