B
One of the most difficult questions to answer is how much a job is worth. We naturally expect that a doctor’s salary will be higher than a bus conductor’s wage. But the question becomes much more difficult to answer when we compare, say, a miner with an engineer, or an unskilled man working on an oil-rig(钻油机) in the North Sea with a teacher in a secondary school. What the doctor, the engineer and teacher have is many years of training in order to obtain the necessary qualifications for their professions. We feel instinctively that these skills and these years, when they were studying instead of earning money, should be rewarded. At the same time we recognize that the work of the miner and the oil-rig laborer is both hard and dangerous, and that they must be highly paid for the risks they take.
Another factor we must take into consideration is how socially useful a man’s work is, regardless of the talents he may bring to it. Most people would agree that looking after the sick or teaching children is more important than, say, selling secondhand cars or improving the taste of toothpaste by adding a red stripe to it. Yet it is almost certain that the used car salesman earns more than the nurse, and that research chemist earns more than the school teacher.
Indeed, this whole question of just rewards can be turned on its head. You can argue that a man who does a job which brings him personal satisfaction is already receiving part of his reward in the form of a so-called “psychic(精神的) wage”, and that it is the man with the boring, repetitive job who needs more money to make up for the soul-destroying monotony(单调) of his work. It is significant that that those jobs which are traditionally regarded as “vocations” --- nursing, teaching and the Church, for example --- continue to be poorly paid, while others, such as those in the world of sport or entertainment, carry financial rewards out of all proportion to their social worth.
Although the amount of money that people earn is in reality largely determined by market forces, this should not prevent us from seeking some way to decide what is the right pay for the job. A starting point for such an investigation would be to try to decide the ratio which ought to exist between the highest and the lowest paid. The picture is made more complicate by two factors: firstly by the “social wage”, i.e, the welfare benefits which every citizen receives; and secondly, by the taxation system, which is often used as an instrument of social justice by taxing high incomes at a very high rate indeed. Allowing for these two things, most countries now regard a ratio of 7:1 as socially acceptable. If it is less, the highly-qualified people carrying heavy responsibilities become disillusioned, and might even end up by emigration(移民) (the so-called “brain-drain” is an evidence that this can happen). If it is more, the gap between rich and poor will be so great that it will lead social tensions and ultimately to violence.
74. The professional man, such as the doctor, should be well paid because ______.
A. he has spent several years learning how to do his job
B. his work involves much great intelligence than, say, a bus conductor’s
C. he has to work much harder than most other people
D. he knows more than other people about his subject
75. The “brain-drain” is an evidence that ______.
A. well-educated people are prepared to emigrate whenever they can get a better paid job
B. people with jobs or responsibility expect to be highly paid
C. high taxation is a useful and effective instrument of social justice
D. the poor are generally more patriotic(爱国的) than the rich
76. As far as rewarding people for their work is concerned, the writer, believes that ______.
A. we should pay for socially-useful work, regardless of the person’s talent
B. we should pay people according to their talents
C. market forces will determine how much a person is paid
D. qualified people should be the highest paid
77. The argument of the “psychic wage” is used to explain why ______.
A. people who do socially important work are not always well paid
B. people who do monotonous jobs are highly paid
C. you should not try to compare the pay of different professions
D. some professional people are paid more than others

PART THREE  READING COMPREHENSION

Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.

A previously unknown kind of human group disappeared from the world so completely that it has left behind the merest piece of evidence that it ever existed — a single bone from the little finger of a child, buried in a cave in the Altai Mountains of southern Siberia.

Researchers removed DNA from the bone and reported that it differed obviously from that of both modern humans and of Neanderthals(尼安德特人), living in Europe until the arrival of modern humans on the continent some 44,000 years ago.

The child carrying the DNA line was probably 5 to 7 years old, but it is not yet known if it was a boy or a girl. The finger bone was unearthed in 2008 from a place known as the Denisova cave.

Researchers are careful not to call the Denisova child a new human species, though it may prove to be so, because the evidence is initial.

But the genetic material removed from the bone, found in a layer laid down on the cave floor between 48,000 and 30,000 years ago, belonged to a distinct human line that traveled out of Africa at a different time from the two known ancient human species. Homo erectus(直立人), found in East Asia, left Africa two million years ago, and the ancestor of Neanderthals moved away some 500,000 years ago. The numbers of differences found in the child’s DNA indicate that its ancestors left Africa about one million years ago.

The region was inhabited by both Neanderthals and modern humans at that time. Counting the new human line, three human species may have lived together.

The standard view has long been that there were three human resettlements out of Africa — those of Homo erectus; of the ancestor of Neanderthals; and finally, some 50,000 years ago, of modern humans. But in 2004, archaeologists reported that they had found the bones of small humans who lived on the Indonesian island of Flores until 13,000 years ago, causing a serious problem to this view. The new line is the second such challenge.

If the nuclear DNA of the Denisova child should differ as much as its mitochondrial(线粒体) DNA does from that of Neanderthals and modern humans, the case for declaring it a new species would be strengthened. But it would be unusual for a new species to be recognized on the basis of DNA alone.

In new diggings starting this summer, archaeologists will look for remains more analytical than the finger bone. Researchers will also begin re-examining the fossil collections in museums to see if any wrongly assigned bones might belong instead to the new line.
