[简答题]C国亚威集团是一家国际化矿业公司,其前身是主营五金矿产进出口业务的贸易公司。
2004年7月,亚威集团在“从贸易型企业向资源型企业转型”的战略目标指引下,对北美N矿业公司发起近60亿美元的收购。当时国际有色金属业正处于低潮,收购时机较好。2005年5月.虽然购并双方进行了多个回合沟通和交流,但N矿业公司所在国政府否决了该收购方案,否决的主要理由有两点:一是是亚威集团资产负债率高达69.82%,其收购资金中有40亿美元由C国国有银行贷款提供,质疑此项收购有C国政府支持;二是亚威集团在谈判过程中一直没有与工会接触,只与N矿业公司管理层谈判,这可能导致收购方案在管理与企业文化整合方面存在不足。
Z公司原是澳洲一家矿产上市公司,其控制的铜、锌、银、铅、金等资源储量非常可观。2008年,国际金融危机爆发,Z公司面临巨大的银行债务压力,于当年11月停牌。之后Z公司努力寻求包括出售股权在内的债务解决方案。亚威有色公司是亚威集团下属子公司,主营业务为生产经营铜、铅、锌、锡等金属产品。2009年6月,经过双方充分协商,亚威有色公司以70%的自有资金,成功完成对Z公司的收购,为获取Z公司低价格的有色金属资源奠定了重要条件。简要分析亚威集团和亚威有色公司通过跨国收购实现国际化经营的主要动机。

Where Have All the Frogs Gone?
In the 1980s,scientists around the world began to notice something strange:Frogs
were disappearing. More recent research has shown that many kinds of amphibians(两栖
动物)are declining or have become extinct. They have been around for a long time一over
350 million years.Why are they dying out now?
Scientists are seriously concerned about this question.First of all,amphibians are an
important source of scientific and medical knowledge.By studying amphibians,scientists
have learned about new substances that could be very useful for treating human diseases.
Further research could lead to many more discoveries,but that will be impossible if the
amphibians disappear.
The most serious aspect of amphibian loss,however,goes beyond the amphibians
themselves.Scientists are beginning to think about what amphibian decline means for the
planet as a whole.If the earth is becoming unlivable for amphibians,is it also becoming
unlivable for other kinds of animals and human beings as well?
Scientists now believe that amphibian decline is due to several environmental factors.
One of these factors is the destruction of habitat,the natural area where an animal lives.
Amphibians are very sensitive to changes in their habitat.If they cannot find the right
conditions,they will not lay their eggs一These days,as wild areas are covered with
houses,roads,farms,or factories,many kinds of amphibians are no longer laying eggs.
For example,the arroyo toad(蟾蜍)of southern California will only lay its eggs on the
sandy bottom of a slow-moving stream.There are very few streams left in southern
California,and those streams are often muddy because of building projects. Not
surprisingily,the arrovo toad is now in danaer of extinction.
There are a number of other factors in amphibian decline.Pollution is one of them.In
many industrial areas,air pollution has poisoned the rain,which then falls on ponds and
kills the frogs and toads that live there,In farming areas,the heavy use of chemicals on
crops has also killed off arrtphibians.Another factor is that air pollution has led to increased
levels of ultraviolet (UV) light. This endangers amphibians, which seem to be especially
sensitive to UV light. And finally, scientists have discovered a new disease that seems to
be killing many species of arnpttibians in different parts of the world.
All these reasons for the disappearance of amphibians are also good reasons for more
general concern. The destrriction of land, the pollcition of the air and the water, the
changes in our atmosphere, the spread of diseases-these factors affect human beings,
too. Amphibians are especially sensitive to environmental change. Perhaps they are like
the canary (金丝雀)bird that coal miners once used to take down into the mines to detect
poisonous gases. When the canary became ill or died,the miners knew that dangerous
gases were near and their own lives were in danger.
Coal miners once used the canary bird to detect
A.poisonous gases.
B.air pollution.
C.water leakage.
D.radiation.
