共用题干第二篇Research by the University of Exeter has revealed that ants have a big impact on their local en-vironment 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,through moving of 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 at-tacked 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 aggressive,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,haying 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 densities of black garden ants and common red ants,both species which can be found across Eurone.including in 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 opposite effect,showing that predation is 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 ecosystems not only because they constitute a great part of the animal 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.What does paragraph 6 tell us?A:Ants bring about a negative influence to an area when their population is small.B:Ants bring about a positive influence to an area when their population is small.C:Ants' predation counteracts the positive influence they may have on an area.D:At higher density,ants produce a positive influence on an area.

The Law to Keep the Oil Industry under Control 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 on Norwegian politician said last week:“We will soon be changed beyond all recognition.” Ever since the war,the Government has been carrying out a programme of development in the area north of the Arctic Circle.During the past few years this programme 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.Norwegian farmers and fishermen have an important influence because _______.A.they form such a large part of Norwegian ideal. B.their lives and values represent the Norwegian ideal. C.their work is so useful to the rest of Norwegian society. D.they regard as a threat to the Norwegian way of life.

共用题干 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,through moving of soil by nest building activity and by collecting food they af-fect 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 Con-servation,said:“Ants are very effective predators which thrive in huge numbers.
