Passage Two

I was only eight years old when the Second World War ended, but I can still remember something about the victory celebrations in the small town where I lived on the day when the war in Europe ended. We had not suffered much from the war there. But both at home and at school I had become accustomed to the phrases "before the war" and "when the war's over". "Before the war", apparently, things had been better, though I was too young to understand why, except that there had been no bombs then, and people had eaten things like ice -cream and bananas, which I had only heard of . When the war was over we would go back to London, but this meant little to me. I did not remember what London was like.

What I remember now about VE (Victory in Europe) Day was the May evening. After dinner I said I wanted to see the bonfire (大火堆) , so when it got dark my father took me to the end of the street. The bonfire was very high, and somehow people had collected some old clothes to dress the un- mistakable figure with the moustache (胡子) they had to put on top of it. Just as we arrived, they set light to it. The flames rose and soon swallowed the "guy". Everyone was cheering and shouting, and an old woman came out of her house with two chairs and threw them on the fire to keep it going.

I stood beside my father until the fire started to go down, not knowing what to say. He said nothing, either. He had fought in the First World War and may have been remembering the end of that. At last he said, "Well, that's it, son. Let's hope that this time it really will be the last one."

40. Where did the author live before the Second World War?

A. In London.

B. In a small town.

C. In Europe.

D. In the countryside.


正确答案:A
40.文章第一段的最后两行,作者说战争结束他们就可以回到伦敦了。由此可见,他们在第二次世界大战前是住在伦敦的,而第二次世界大战期间是住在一个小镇。选项 A是正确的。

To Survive or to Vanish

1.Over 3.6 billion years ago,the first creature was born in the world.Since then,the earth started its era with life.The history of life on earth has been a history of interaction between living things and their surroundings.To a large extent,the physical form and the habits of the earth's vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time,the opposite effect,in which life actually modifies its surroundings,has been relatively slight. Only in the present century has one species一man acquired significant power to alter the nature of his world.
2.During the past 25 years,this power has not only become increasingly great but it has changed in character. The most alarming of all man's assaults upon the environment is the contamination of air,earth,rivers,and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable.In this now universal contamination of the environment,chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil,entering into living organisms, passing from one to another in a chain of poisoning and death.Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation,sicken cattle,and work unknown harm on those who drink from once pure wells."Man can hardly even recognize the devils of his own creation,"as a scientist has said.
3.Hundreds of millions of years have passed before the globe produced the life that now inhabits the earth.Given time not in years but in millennia life adjusts,and a balance has been reached.But in the modern world there is no time.
4.The quick steps of change follows the impetuous pace of man rather than the deliberate pace of nature.Radiation is now the unnatural creation of man's tampering with the atom.The chemicals are the synthetic creations of man's inventive mind,having no counterparts in nature.
5.To survive these chemicals would require not merely the years of one man's life but the life of generations.And even this,were it by some miracle possible,would be futile,for the new chemicals come from our laboratories in an endless stream;almost five hundred annually find their way into actual use in the United States alone.Among them are many that are used in man's war against nature.Since the mid l940's over 200 basic chemicals have been created for use in killing insects,weeds,and other organisms described as"pests".
6.It is not my contention that chemical insecticides must never he used.I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons,without their consent and often without their knowledge.I contend,furthermore,that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil,water,wildlife,and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.

The effect of life modifying its surroundings has been_______.
A:man's tampering with the atom
B:enormous numbers of people to contact with these poisons
C:the integrity of the natural world that supports all life
D:inventive
E:irrecoverable
F:relatively slight

答案:F

第5题:

Passage 2
If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for us to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan.
Sagan believes that before the earth's resources are completely exhausted it will be possible to change the atmosphere of Venus and so create a new world almost as large as earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.
Sagan proposes that algae organisms, which can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be bred in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.
When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for men to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.
CarlSagan believes that Venus might be colonized from earth because__________.

A. it might be possible to change its atmosphere
B. its atmosphere is the same as the earth's
C. there is a good supply of water on Venus
D. the days on Venus are long enough

答案:A
解析:
由第二段第一句中的“itwill be possible to change the atmosphere ofVenus and so create a new worl d”可知.so是表示因果的连接词,前因后果,所以正确答案A。

Text 4

Jill Ker Conway ,president of Smith ,echoes the prevailing view of contemporary technology when she says that " anyone in today's world who doesn't understand data processing is not educated. " But she insists that the mcreasing emphasis on these matters leave certain gaps. Says she: "The very strongly utilitarian emphasis in education ,which is an effect of man-made satellites and the cold war, has really removed from this culture something that was very profound in its 18th and 19th century roots ,which was a sense that literacy and learning were ends in themselves for a demo- cratic republic. "

In contrast to Plato's claim for the social value of education,a quite different idea of intellectu-al purposes was advocated by the Renaissance humanists. Ovejoyed with their rediscovery of the classical leaming that was thought to have disappeared during the Dark Ages,they argued that the imparting of knowledge needs no justification-religious ,social ,economic ,or political. Its purpose,to the extent that it has one ,is to pass on from generation to generation the corpus of knowledge that constitutes civilization. "What could man acquire ,by virtuous striving ,that is more valuable than knowledge?" asked Erasmus ,perhaps the greatest scholar of the early 16th century. That idea has acquired a tradition of its own. "The educational process has no end beyond itself," said John Dewey. "It is its own end. "

But what exactly is the corpus of knowledge to be passed on? In simpler times ,it was all included in the medieval universities' Quadrivium ( arithmetic, geometry, astronomy, music ) and Trivium( grammar, thetoric ,logic). As recently as the last century ,when less than 5% of Americans went to college at all, students in New England establishments were compelled mainly to memorize and recite various Latin texts,and crusty professors angrily opposed the introduction of any new scientific discoveries or modern European languages. "They felt," said regretfully Charles Francis Adams, Jr. ,the Union Pacific Railroad president who devoted his later years to writing history ,"that a classical education was the important distinction between a man who had been to college and a man who had not been to college ,and that anything that diminished the importance of this distinction was essentially revolutionary and tended to anarchy. "

56. The first paragraph shows that Jill Ker Conway accepts utilitarian emphasis in education

[A] wholeheartedly.

[B] with reservation.

[C] against her own will.

[D] with contempt.


正确答案:B
56.B【精析】该题为推理题。根据第一段第二句“But she insists that the increasing emphasis on these matters leave certain gaps.”我们知道,虽然吉尔-克尔·康维支持实用主义教育,但是她认为实用主义教育仍然有一些欠缺,故选择B项。

第7题:

(a) Kayte operates in the shipping industry and owns vessels for transportation. In June 2014, Kayte acquired Ceemone whose assets were entirely investments in small companies. The small companies each owned and operated one or two shipping vessels. There were no employees in Ceemone or the small companies. At the acquisition date, there were only limited activities related to managing the small companies as most activities were outsourced. All the personnel in Ceemone were employed by a separate management company. The companies owning the vessels had an agreement with the management company concerning assistance with chartering, purchase and sale of vessels and any technical management. The management company used a shipbroker to assist with some of these tasks.

Kayte accounted for the investment in Ceemone as an asset acquisition. The consideration paid and related transaction costs were recognised as the acquisition price of the vessels. Kayte argued that the vessels were only passive investments and that Ceemone did not own a business consisting of processes, since all activities regarding commercial and technical management were outsourced to the management company. As a result, the acquisition was accounted for as if the vessels were acquired on a stand-alone basis.

Additionally, Kayte had borrowed heavily to purchase some vessels and was struggling to meet its debt obligations. Kayte had sold some of these vessels but in some cases, the bank did not wish Kayte to sell the vessel. In these cases, the vessel was transferred to a new entity, in which the bank retained a variable interest based upon the level of the indebtedness. Kayte’s directors felt that the entity was a subsidiary of the bank and are uncertain as to whether they have complied with the requirements of IFRS 3 Business Combinations and IFRS 10 Consolidated Financial Statements as regards the above transactions. (12 marks)

(b) Kayte’s vessels constitute a material part of its total assets. The economic life of the vessels is estimated to be 30 years, but the useful life of some of the vessels is only 10 years because Kayte’s policy is to sell these vessels when they are 10 years old. Kayte estimated the residual value of these vessels at sale to be half of acquisition cost and this value was assumed to be constant during their useful life. Kayte argued that the estimates of residual value used were conservative in view of an immature market with a high degree of uncertainty and presented documentation which indicated some vessels were being sold for a price considerably above carrying value. Broker valuations of the residual value were considerably higher than those used by Kayte. Kayte argued against broker valuations on the grounds that it would result in greater volatility in reporting.

Kayte keeps some of the vessels for the whole 30 years and these vessels are required to undergo an engine overhaul in dry dock every 10 years to restore their service potential, hence the reason why some of the vessels are sold. The residual value of the vessels kept for 30 years is based upon the steel value of the vessel at the end of its economic life. At the time of purchase, the service potential which will be required to be restored by the engine overhaul is measured based on the cost as if it had been performed at the time of the purchase of the vessel. In the current period, one of the vessels had to have its engine totally replaced after only eight years. Normally, engines last for the 30-year economic life if overhauled every 10 years. Additionally, one type of vessel was having its funnels replaced after 15 years but the funnels had not been depreciated separately. (11 marks)

Required:

Discuss the accounting treatment of the above transactions in the financial statements of Kayte.

Note: The mark allocation is shown against each of the elements above.

Professional marks will be awarded in question 3 for clarity and quality of presentation. (2 marks)


正确答案:

(a) The accounting for the transaction as an asset acquisition does not comply with the requirements of IFRS 3 Business Combinations and should have been accounted as a business combination. This would mean that transaction costs would be expensed, the vessels recognised at fair value, any deferred tax recognised at nominal value and the difference between these amounts and the consideration paid to be recognised as goodwill.

In accordance with IFRS 3, an entity should determine whether a transaction is a business combination by applying the definition of a business in IFRS 3. A business is an integrated set of activities and assets which is capable of being conducted and managed for the purpose of providing a return in the form. of dividends, lower costs or other economic benefits directly to investors or other owners, members or participants. A business consists of inputs and processes applied to those inputs which have the ability to create outputs. Although businesses usually have outputs, outputs are not required to qualify as a business.

When analysing the transaction, the following elements are relevant:

(i) Inputs: Shares in vessel owning companies, charter arrangements, outsourcing arrangements with a management company, and relationships with a shipping broker.

(ii) Processes: Activities regarding chartering and operating the vessels, financing the business, purchase and sales of vessels.

(iii) Outputs: Ceemone would generate revenue from charter agreements and has the ability to gain economic benefit from the vessels.

IFRS 3 states that whether a seller operated a set of assets and activities as a business or intends to operate it as a business is not relevant in evaluating whether it is a business. It is not relevant therefore that some activities were outsourced as Ceemone could chose to conduct and manage the integrated set of assets and activities as a business. As a result, the acquisition included all the elements which constitute a business, in accordance with IFRS 3.

IFRS 10 Consolidated Financial Statements sets out the situation where an investor controls an investee. This is the case, if and only if, the investor has all of the following elements:

(i) power over the investee, that is, the investor has existing rights which give it the ability to direct the relevant activities (the activities which significantly affect the investee’s returns);

(ii) exposure, or rights, to variable returns from its involvement with the investee;

(iii) the ability to use its power over the investee to affect the amount of the investor’s returns.

Where a party has all three elements, then it is a parent; where at least one element is missing, then it is not. In every case, IFRS 10 looks to the substance of the arrangement and not just to its legal form. Each situation needs to be assessed individually. The question arises in this case as to whether the entities created are subsidiaries of the bank. The bank is likely to have power over the investee, may be exposed to variable returns and certainly may have the power to affect the amount of the returns. Thus the bank is likely to have a measure of control but the extent will depend on the constitution of the entity.

(b) Kayte’s calculation of the residual value of the vessels with a 10-year useful life is unacceptable under IAS 16 Property, Plant and Equipment because estimating residual value based on acquisition cost does not comply with the requirements of IAS 16. Kayte should prepare a new model to determine residual value which would take account of broker valuations at the end of each reporting period and which would produce zero depreciation charge when estimated residual value was higher than the carrying amount.

IAS 16 paragraph 6 defines residual value as the estimated amount which an entity would currently obtain from disposal of the asset, after deducting the estimated costs of disposal, if the asset were already at the age and in the condition expected at the end of its useful life.

IAS 16 requires the residual value to be reviewed at least at the end of each financial year end with the depreciable amount of an asset allocated on a systematic basis over its useful life. IAS 16 specifies that the depreciable amount of an asset is determined after deducting its residual value.

Kayte’s original model implied that the residual value was constant for the vessel’s entire useful life. The residual value has to be adjusted especially when an expected sale approaches, and the residual value has to come closer to disposal proceeds minus disposal costs at the end of the useful life. IAS 16 says that in cases when the residual value is greater than the asset’s carrying amount, the depreciation charge is zero unless and until its residual value subsequently decreases to an amount below the asset’s carrying amount. The residual value should be the value at the reporting date as if the vessel were already of the age and in the condition expected at the end of its useful life. An increase in the expected residual value of an asset because of past events will affect the depreciable amount, while expectation of future changes in residual value other than the effects of expected wear and tear will not. There is no guidance in IAS 16 on how to estimate residual value when the useful life is considered to be shorter than the economic life. Undesirable volatility is not a convincing argument to support the accounting treatment, and broker valuations could be a useful starting point to estimate residual value.

As regards the vessels which are kept for the whole of their economic life, a residual value based upon the scrap value of steel is acceptable. Therefore the vessels should be depreciated based upon the cost less the scrap value of steel over the 30-year period. The engine need not be componentised as it will have the same 30-year life if maintained every 10 years. It is likely that the cost of major planned maintenance will increase over the life of a vessel due to inflation and the age of the vessel. This additional cost will be capitalised when incurred and therefore the depreciation charge on these components may be greater in the later stages of a vessel’s life.

When major planned maintenance work is to be undertaken, the cost should be capitalised. The engine overhaul will be capitalised as a new asset which will then be depreciated over the 10-year period to the next overhaul. The depreciation of the original capitalised amount will typically be calculated such that it had a net book value of nil when the overhaul is undertaken.

This is not the case with one vessel, because work was required earlier than expected. In this case, any remaining net book value of the old engine and overhaul cost should be expensed immediately.

The initial carve out of components should include all major maintenance events which are likely to occur over the economic life of the vessel. Sometimes, it may subsequently be found that the initial allocation was insufficiently detailed, in that not all components were identified. This is the case with the funnels. In this situation it is necessary to determine what the net book value of the component would currently be had it been initially identified. This will sometimes require the initial cost to be determined by reference to the replacement cost and the associated accumulated depreciation charge determined using the rate used for the vessel. This is likely to leave a significant net book value in the component being replaced, which will need to be written off at the time the replacement is capitalised.

Passage Three

Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form. a crust of rock that was many miles thick.

Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.

In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.

The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.

41. This passage mainly talks about ______.

A. the origin of the earth

B. the origin of the ocean

C. the history of the earth

D. the forming of the earth's crust

Chemicals sprayed on croplands or forests or gardens lie long in soil,entering into living organisms, passing from one to another in a chain of poisoning and death.Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation,sicken cattle,and work unknown harm on those who drink from once pure wells."Man can hardly even recognize the devils of his own creation,"as a scientist has said.
3.Hundreds of millions of years have passed before the globe produced the life that now inhabits the earth.Given time not in years but in millennia life adjusts,and a balance has been reached.But in the modern world there is no time.
4.The quick steps of change follows the impetuous pace of man rather than the deliberate pace of nature.Radiation is now the unnatural creation of man's tampering with the atom.The chemicals are the synthetic creations of man's inventive mind,having no counterparts in nature.
5.To survive these chemicals would require not merely the years of one man's life but the life of generations.And even this,were it by some miracle possible,would be futile,for the new chemicals come from our laboratories in an endless stream;almost five hundred annually find their way into actual use in the United States alone.Among them are many that are used in man's war against nature.Since the mid l940's over 200 basic chemicals have been created for use in killing insects,weeds,and other organisms described as"pests".
6.It is not my contention that chemical insecticides must never he used.I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons,without their consent and often without their knowledge.I contend,furthermore,that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil,water,wildlife,and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.

Paragraph 1_______
A:Man should be cautious in chemical use.
B:It takes generations for mankind to adapt themselves to the chemicals.
C:Chemicals are human's invention
D:Human's power increases and has changed its character in the past quarter century.
E:The new change in the relationship between earth and its creature一human's power playing a greater role in changing the world
F: Modern world gives no time for nature to adjust to human.

答案:E
解析:
本题考查的是对所读材料大意与主旨的掌握。第一段前面大部分内容在说生物适应自然的内容,但最后一句用“only”引出本文要强调的新变化:人类对自然的影响。这与选项E中提到的:The new change in the relationship between earth and its creature一human's power playing a greater role in changing the world.地球与其生物之间关系的新变化——人类在改造世界的进程中起到更大的作用,意义相符,所以E是答案。
本题考查的是对所读材料大意与主旨的掌握。第二段第一句是本段的主旨句:"During the past 25 years,this power has not only become increasingly great but it has changed in character.”在过去的25年中,这种力量不仅日趋强大,而且其性质也发生了变化。其中,“这种力量指的是人改造自然的力量”,这与选项D中提到的:" Human's power increases and has changed its character in the past quarter century.”意思相符。所以D是答案。
本题考查的是对所读材料大意与主旨的掌握。第五段第一句是主旨句:"To survive these chemicals would require not merely the years of one man's life but the life of generations.”为了在这些化学制品中存活下来,人类需要付出的不只是一个人一生的时间,而是几代人的时间。选项B中提到:" It takes generations for mankind to adapt themselves to the chemicals.”概括了本段的大意,所以B是答案。
本题考查的是对所读材料大意与主旨的掌握。第六段通过两个“I (do) contend”引出对于人类错误使用化学物质并对此疏于监管表示担忧。选项A是答案,因为 " Man should be cautious in chemical use.”人类应该小心使用化学物质,概括了本段的大意。
本题考查的是对阐述文章的事实与细节的了解。依据是第一段倒数第二句:"Considering the whole span of earthly time,the opposite effect,in which life actually modifies its surroundings , has been relatively slight.”将地球上生命存在的整个时期加以考虑,相反作用,即生命对其周围环境的实际改变作用,却相对很小。题干出现:生命改变其环境的影响,选项 F是relatively slight相对较小,与原文意思一致,证明了选项F是正确的。
本题考查的是对阐述文章的事实与细节的了解。选E的依据是第二段第三句“This pollution is for the most part irrecoverable.”而这种污染在很大程度上是无法挽救的。而题目中:人类对于自然的污染是在很大程度上______,缺少的信息正是选项E irrecoverable无法挽救的。
本题考查的是对阐述文章的事实与细节的了解。选A的依据是第四段的第二句:" Radiation is now the unnatural creation of man's tampering with the atom.”辐射是当今人类通过支配原子而得到的一种非自然的创造物。而选项A与题干结合的意思与之一致,所以 A是答案。
本题考查的是对阐述文章的事实与细节的了解。选C的依据是全文的最后一句:" Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.”我们缺乏对万物赖以生存的自然界的生态完整性的关心,对此,后代是不可能原谅我们的。题干与选项C结合后与信息句意思一致。所以C是答案。
