The growth of population during the past few centuries is no proof that population will co

ntinue to grow straight upward' toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one million B. C. , followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either 'way contrary to popular belief in constant geometric growth--population can be expected in the long run to adjust to productivity.Which of the following is NOT TRUE according to the passage？A.Human population expands at a straight upward trend.B.Population growth has shown ups and downs in demographic history.C.Population growth can not be regarded as a social failure.D.Increase in population is related to productivity.

第4题

Ours has become a society of employees. A hundred years or so ago only one out of every fi

ve Americans at work was employed, i. e. , worked for somebody else. Today only one out of five is not employed but working for himself. And when fifty years ago "being employed" meant working as a factory laborer or as a farmhand, the employee of today is increasingly a middle-class person with a substantial formal education, holding a professional or management job requiring intellectual and technical skills. Indeed, two things have characterized American society during these last fifty years: middle-class and upper-class employees have been tile fastestgrowing groups in our working population—growing so fast that the industrial worker, that oldest child of the Industrial Revolution, has been losing in numerical importance despite the expansion of industrial production.

Yet you will find little if anything written on what it is to be an employee. You can find a great deal of very dubious advice on how to get a job or how to get a promotion. You can also find a good deal of work in a chosen field, whether it be the mechanist's trade or book-keeping(簿记). Every one of these trades requires different skills, sets different standards, and requires a different preparation. Yet they all have employeeship in common. And increasingly, especially in the large business or in government, employeeship is more important to success than the special professional knowledge or skill. Certainly more people fail because they do not know the requirements of being an employee than because they do not adequately possess the skills of their trade; the higher you climb the ladder, the more you get into administrative or executive work, the greater the emphasis on ability to work within the organization rather than on technical abilities or professional knowledge.

It is implied that fifty years ago _______.

A．eighty per cent of American working people were employed in factories

B．twenty per cent of American intellectuals were employees

C．the percentage of intellectuals in the total work force was almost the same as that of industrial workers

D．the percentage of intellectuals working as employees was not so large as that of industrial workers

第5题

In the opinion of many Americans and Europeans, we only began to really explore our world

in the sixteenth century. According to them, the sailors of the ancient world did not explore distant parts of the world; they did not have the necessary knowledge or skills for long sea journeys. However, the people who have this opinion are forgetting two important facts of history.

First, sometimes early scientists have an idea which is correct, but scientists in later centuries do not believe it. For example, about 270 B. C., a Greek scientist had an idea which we all believe today: The earth moves around the sun. But for the following 1,600 years scientists did not believe this. In their opinion, the sun clearly moved around the earth. They discovered the truth again only in the fifteenth century!

The second fact of history that many people forget is this: Ancient does not mean primitive. For example, the ancient Egyptians knew a great deal about the stars; they used this knowledge to find their way across the oceans. Two thousand years ago a Greek scientist who lived in Egypt calculated the distance around the earth. The results of his calculations were close to the real distance we know today! So the ancients had a great deal of scientific knowledge. They also had skills which equaled the skills of to- day. For example, 1,300 years ago and before, fishermen in Ireland built their boats of wood and leather. Today some fishermen in Ireland still make boats of the same de- sign. They use tools and materials which are not very different from the tools and materitals which their ancestors used. Why？ The ancient design of the boats was good, and with skillful sailors, these boats can sail in all kinds of weather.

Clearly long before the sixteenth century, people had the skill, the knowledge and the equipment which were necessary for long journeys by sea. The world did not have to wait until the sixteenth century for its first explorers!

Which of the following statements is consistent with the passage？

A．According to the writer, we only began to really explore the world in the sixteenth century.

B．In the history of science, people sometimes have to discover a fact a second time.

C．The ancient Egyptians had very little knowledge about the stars.

D．The writer agrees with many Americans and Europeans except for the two facts mentioned in the passage.

After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple of

Emperors of Successive Dynasties, was reopened to the public last weekend. Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors. It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School. The temple's Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The finzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the re-opening of the temple, finzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carded out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.What does the verb form. of the word "renovation" mean in Para.1？A.Reform. B.Rearrange. C.Retreat. D.Restore.

Section B – TWO questions ONLY to be attempted

Five years ago, George Woof was appointed chief executive offi cer (CEO) of Tomato Bank, one of the largest global banks. Mr Woof had a successful track record in senior management in America and his appointment was considered very fortunate for the company. Analysts rated him as one of the world’s best bankers and the other directors of Tomato Bank looked forward to his appointment and a signifi cant strengthening of the business.

One of the factors needed to secure Mr Woof’s services was his reward package. Prior to his acceptance of the position, Tomato Bank’s remuneration committee (comprised entirely of non-executives) received a letter from Mr Woof saying that because his track record was so strong, they could be assured of many years of sustained growth under his leadership. In discussions concerning his pension, however, he asked for a generous non-performance related pension settlement to be written into his contract so that it would be payable whenever he decided to leave the company (subject to a minimum term of two years) and regardless of his performance as CEO. Such was the euphoria about his appointment that his request was approved. Furthermore in the hasty manner in which Mr Woof’s reward package was agreed, the split of his package between basic and performance-related components was not carefully scrutinised. Everybody on the remuneration committee was so certain that he would bring success to Tomato Bank that the individual details of his reward package were not considered important.

In addition, the remuneration committee received several letters from Tomato Bank’s fi nance director, John Temba, saying, in direct terms, that they should offer Mr Woof ‘whatever he wants’ to ensure that he joins the company and that the balance of benefi ts was not important as long as he joined. Two of the non-executive directors on the remuneration committee were former colleagues of Mr Woof and told the fi nance director they would take his advice and make sure they put a package together that would ensure Mr Woof joined the company.

Once in post, Mr Woof led an excessively aggressive strategy that involved high growth in the loan and mortgage books fi nanced from a range of sources, some of which proved unreliable. In the fi fth year of his appointment, the failure of some of the sources of funds upon which the growth of the bank was based led to severe fi nancing diffi culties at Tomato Bank. Shareholders voted to replace George Woof as CEO. They said he had been reckless in exposing the company to so much risk in growing the loan book without adequately covering it with reliable sources of funds.

When he left, the press reported that despite his failure in the job, he would be leaving with what the newspapers referred to as an ‘obscenely large’ pension. Some shareholders were angry and said that Mr Woof was being ‘rewarded for failure’. When Mr Woof was asked if he might voluntarily forego some of his pension in recognition of his failure in the job, he refused, saying that he was contractually entitled to it and so would be keeping it all.

Required:

(a) Criticise the performance of Tomato Bank’s remuneration committee in agreeing Mr Woof’s reward package. (10 marks)

(b) Describe the components of an appropriately designed executive reward package and explain why a more balanced package of benefi ts should have been used to reward Mr Woof. (10 marks)

(c) Construct an ethical case for Mr Woof to voluntarily accept a reduction in his pension value in recognition of his failure as chief executive of Tomato Bank. (5 marks)

Millions of stars are traveling about in space. A few form. groups which journey together,

but most of them travel alone. And they travel through a universe so large that one star seldom comes near to another.

We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun. Just as the sun and the moon raise tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave' must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星).

Millions of stars are______.

A．following a regular path in space

B．always travelling together

C．seldom wandering about in the universe

D．moving about without a fixed course

Passage Two Modern humans emerged some 250,000 years ago, yet agriculture is a fairly

recent invention, only about 10,000 years old. Many crop plants are rather new additions to our diet: broccoli (a flowering mutant of kale) is thought to be only 500 years old. Most innovation is far more recent still. Although Austrian monk Gregor Mendel's pea plant experiments quietly laid the basic foundations of genetics in the mid-19th century, his work was rediscovered and applied to crop breeding only at the beginning of the 20th century. Further advances have steadily accumulated. The 1940s saw the identification of DNA as genetic material and the adoption, by commercial breeders, of genetic modification - typically by applying chemicals or radiation to DNA to try to make plants with advantageous characteristics. The modifications ultimately led to the green revolution of the 1960s and 1970s, during which time global wheat yields tripled. The 1980s and 1990s saw the commercial adoption of agricultural biotechnology, which has allowed breeders to introduce specific genes into crops from the same or different species. In 2004 the first plant genome was fully sequenced, and since then the number of plant gene sequences in GenBank, the public repository for gene sequence information, has been doubling every two years. Our knowledge is increasing exponentially, as it has been in other fields such as semiconductors and cellular telephony. Our challenge is to increase agricultural yields while decreasing the use of fertilizer, water, fossil fuels and other negative environmental inputs. Embracing human ingenuity and innovation seems the most likely path. Plants did not evolve to serve humans, and their sets of genes are incomplete for our purposes. The integral role of modifying genes is obvious to all breeders, though sometimes painfully absent from the public's understanding of how modern agriculture succeeds. All breeding techniques, from before Mendel's time until today, exploit modifications to plant DNA. These modifications can take the form. of mistakes or mutations that occur during natural cell division in the wild; the natural but random movement of DNA sequences from one part of a plant's genome to another; or the more precise insertion of known gene sequences using biotechnology. In all these cases, plant genes are moved within or across species, creating novel combinations. Hybrid genetics - the combination of different versions of the same gene – has resulted in spectacular yield increases. Largely as the consequence of using hybrid seed varieties, corn yields in the U.S. have increased more than 500 percent in the past 70 years. Questions 6-10 are based on Passage Two.

(1)Which statement is correct according to paragraph one？

A、Broccoli was first bred by Mendel

B、Broccoli wasn’t considered edible until 500 years ago

C、Mendel's work was considered most important in the history of genetics

D、Mendel’s study found its major application some 100 years ago

(2)What was cited as a result of the green revolution？

A、Sharp rise in worldwide wheat production

B、Extensive use of organic fertilizer

C、Large-scale adoption of genetic modification

D、Commercial success of genetically modified seeds.

(3)Which statement is true of GenBank according to the passage？

A、The number of gene sequences has doubled since its foundation
