第3题
Britain's undeclared general election campaign has already seen the politicians trading nu
mbers as boxers trade punches. There is nothing new in such statistical slanging matches(相互谩骂). What is new is an underestimation of worry about what has been happening to official statistics under the Labour government.

One of the most important figures for Gordon Brown when presenting his pre-election budget on March 16th was the current-budget balance. This is the gap between current revenues and current spending. It matters to the chancellor of the exchequer(财政部长) because he is committed to meeting his own "golden rule" of borrowing only to invest, so he has to ensure that the current budget is in balance or surplus over the economic cycle.

Mr. Brown told MPs that he would meet the golden rule for the current cycle with & 6 billion ($11.4 billion) to spare—a respectable-sounding margin, though much less than in the past. However, the margin would have been halved but for an obscure technical change announced in February by the Office for National Statistics to the figures for road maintenance of major highways. The ONS said that the revision was necessary because it had been double-counting this spending within the current budget.

If this were an isolated incident, then it might be disregarded. But it is not the first time that the ONS has made decisions that appear rather convenient for the government. Mr. Brown aims to meet another fiscal rule, namely to keep pubic net debt below 40% of GDP, again over the economic cycle. At present he is meeting it but his comfort room would be reduced if the & 21 billion borrowings of Network Rail were included as part of public debt. They are not thanks to a controversial decision by the ONS to classify the rail-infrastructure corporation within the private sector, even though the National Audit Office, Parliament's watchdog, said its borrowings were in fact government liabilities.

This makes it particularly worrying that the official figures can show one thing, whereas the public experiences another. One of the highest-profile targets for the NHS is that no patient should spend more than four hours in a hospital accident and emergency department. Government figures show that by mid-2004, the target was being met for 96% of patients. But according to a survey of 55,000 patients by the Healthcare Commission, an independent body, only 77% of patients said they stayed no more than four hours in A&E.

One way to help restore public confidence in official statistics would be to make the ONS independent, as the Conservatives and Liberal Democrats have suggested. Another would be for the National Audit Office to assess how the government has been performing against targets, as the Public Administration Committee has recommended.

It can be inferred from the first paragraph that

A.the British politicians are often compared to boxers by the people.

B.it is a common practice that the government plays with figures.

C.people often overestimate the credibility of official statistics.

D.the Labor government usually underestimate its official figures.

Many IQ tests show that there are no significant differences in the mean, or average score

When a new IQ test, is being constructed, it is quite easy to find test(51)that are not answered correctly(52)the same proportions of men and women,(53)these are usually then eliminated from the test.

If we regard some arbitrary lower score on a test as a classification like "educational subnormal(智力上逊常的人)" (ESN) and some equally arbitrary(61)score as "gifted", we then find that there is higher ratio of ESN males to women and likewise we(62)that there are more gifted men than women, even though the average scores are the same.

Section B

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.

Though it now seems merely an episode in the last year of World War I, the influenza pandemic of the autumn of 1918 was one of the three greatest outbreaks of disease in history. Only the plague of Justinian and the Black Death compare with it. A quarter of the world's population was affected; all in all, it killed 22 million people, almost twice as many as were killed in the war itself. In India, more people died from influenza in a few months than had died from cholera in twenty years. In the United States, half a million people died.

Through centuries, the course of epidemics has run from east to west. The 1918 influenza epidemic followed this pattern, reaching America last. Traditionally, Asia has been the matrix of disease, almost as though there existed, in the vastness of Mongolia, a permanent focus of infection which would erupt periodically into the rest of the world. Some doctors maintained that the influenza was introduced by Chinese labor battalions that landed on the coast of France. Some attributed it to Russian soldiers arriving from Vladivostock. Others thought it might have developed in Spain from an earlier bronchitis which was so prevalent during the spring that the name "Spanish" was given to the autumn influenza. There was even one tenuous theory that the disease sprang into being in an isolated Georgia training camp during the winter of 1917 and migrated westward until it had circumnavigated the earth.

Influenza is still a mysterious disease. No one yet knows whether it is one virus or several, why it occurs in cycle, or how and where it lies dormant between epidemics. There are theories of weather, theories of the wearing off of group immunity, and even a theory of determination by economic circumstances. The most generally held current explanation is, however, that a pandemic like that of 1918 arises when a new and explosive strain of virus develops through a spontaneous process of mutation or renewal.

What is this article about?

A.The Black Plague.

B.The flu epidemic of 1918.

C.The Plague of Justinian.

D.All epidemics.
