单选题 Although we already know a great deal about influenza, and although the World Health Organization is constantly collecting detailed information from its chain of influenza reference laboratories throughout the world, it is extremely difficult for epidemiologists (流行病专家), who study infectious disease, to predict when and where the next flu epidemic will occur, and how severe it will be. There are three kinds of influenza virus, known as A, B and C. Influenza C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies which confer immunity to that strain of virus, but a virus with the capacity to change its character is able to by-pass this protection. Variability is less developed in the influenza B virus, which affects only human beings. An influenza B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The influenza A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the unparalleled pandemic, or world epidemic, of 1918-1919, when about half the world's population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complications(并发症) caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence, the ease with which it can be transmitted and the strength of the opposition it encounters. Scientists, however, have a reliable general picture of the world situation. Influenza A attacks us in waves every two or three years, while influenza B, which travels more slowly, launches its main assaults every three to six years. The outbreaks vary from isolated cases to epidemics involving a tenth or more of the population. We may confidently prophesy that sooner or later large numbers of people will be feeling the unpleasant effects of some kind of influenza virus.

单选题 The law says that women should have the chance of doing the same jobs as men and earn the same as them. The reality is very different. Women lose because, 25 years after the Equal Pay Act, many of them still get paid less than men. They lose because they do lower-paid jobs which men just won't consider. And they lose because they are the ones who interrupt a career to have children. All this is reported in an independent study ordered by the Government's Women's Unite. The biggest problem isn't equal pay in workplaces such as factories. It is a sort of work women do. Make a list of the low-paid jobs, then consider who does them. Try nurses, secretaries, cleaners, clerks, teachers in primary schools, dinner ladies, and child care helpers. Not a lot of men among that group, are there? Yet some of those jobs are really important. Surely no one would deny that about nurses and teachers, for a start. So why do we reward the people who do them so poorly? There can be only one answer——because they are women. This is not going to be put right overnight. But the Government which employs a lot of them, and other bosses have to make a start. It is disgraceful (可耻的) that we have gone into the 21st Century but still treat women as second-class citizens.

单选题With only about l，000 pandas left in the world，China is desperately trying to clone the animal and save the endangered species．That’s a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a proj ect called“Noah’sArk”． Dr．Duane Kraemer，a professor in Texas A&M’s College of Veterinary Medicine and a pioneer in embryo(~胎)transfer work and related procedures，says he salutes the Chinese effort and“1 wish them all the best success possible．It’S a worthwhile project，certainly not an easy one，and it’s very much like what we’re attempting here at Texas A&M—to save animals from extinction．” Noah’s Ark is aimed at collecting eggs，embryos，semen(精子)and DNA of endangered animals and storing them in liquid nitrogen．If certain species should become extinct，Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future． It is estimated that as many as 2，000 species of mammals，birds and reptiles will become extinct over the next 1 00 years．The panda，native only to China，is in danger of becoming extract In the next 25 years． This week，Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit．They are now trying to implant the embryo into a host animal． The entire procedure could take from three to five years tO complete． “The nuclear transfer of one species to another is not easy，and the lack of available panda eggs could be a major problem，”Kraemer believes．“They will probably have to do several hundred transfers to resuIt in one pregnancy．It take s a long time and it’s difficult，but this could be groundbreaking science if it works．They are certainly not putting any live pandas at risk，so it is worth the effort，”adds Kraemer，who is one of the leaders of the Missyplicity ProJect at Texas A&M，the first ever attempt at cloning a dog． “They are trying to do something that’s never been done，and this is very similar to our work in Noah’s Ark．We’re both trying to save animals that face extinction．I certainly applaud their effort and there’s a lot we can learn from what they are attempting to do．It’s a research that is very much needed．”

单选题When Liam McGee departed as president of Bank of America in August，his explanation was McGee says leaving without a position lined up gave him time to reflect on what kind of company he wanted to run．It also sent a clear message to the outside world about his aspirations．And McGee isn’t alone．In recent weeks the No．2 executives at Avon and American Express quit with the explanation that they were looking for a CEO post．As boards scrutinize succession plans in response to shareholder pressure，executives who don’t get the nod also may wish to move on．A turbulent business environment also has senior managers cautious of letting vague pronouncements cloud their reputations． As the first signs of recovery begin to take hold，deputy chiefs may be more willing to make the jump without a net．In the third quarter，CEO turnover was down 23％from a year ago as nervous boards stuck with the leaders they had。according to Liberum Research．As the economy picks up，opportunities will abound for aspiring leaders． The decision to quit a senior position to look for a better one is unconventional．For years executives and headhunters have adhered to the rule that the most attractive CEO candidates are the ones who must be poached．Says Korn Ferry，senior partner Dennis Carey：“I can’t think of a single search I’ve done where a board has not instructed me to look at sitting CEOs first．” Those who jumped without a job haven’t always landed in top positions quickly．Ellen Marram quit as chief of Tropicana when the business became part of PepsiCo(PEP)a decade ago，saying she wanted to be a CEO．It was a year before she became head of a tiny Internet-based commodities exchange．Robert Willumstad left Citigroup in 2005 with ambitions to be a CEO．He finally took that post at a major financial institution three years later． Many recruiters say the old disgrace is fading for top performers．The financial crisis has made it more acceptable to be between jobs or to leave a bad one．“The traditional rule was it’s safer to stay where you are。but that’s been fundamentally inverted，”says one headhunter．“The people who’ve been hurt the worst are those who’ve stayed too long．”

单选题__________，Mr．Smith is willing to give money to begger．

单选题G President Arling has put his long-awaited economic restructuring program before the Congress. It provides a coordinated program of investment credits, research grants, educational reforms, and tax changes designed to make American industry more competitive. This is necessary to reverse the economic slide into unemployment, lack of growth, and trade deficits that have plagued the economy for the past six years. The most liberal wing of the President's party has called for stronger and more direct action. They want an incomes policy to check inflation while Federal financing helps rebuild industry behind a wall of protective tariffs. The Republicans, however, decry even the modest, graduated tax increases in the President's program. They Want tax cuts and a more open market. They say if Federal money has to be injected into the economy, let it through defence spending. Both these alternatives ignore the unique nature of the economic problem before us. It is not simply a matter of markets or financing. The new technology allows vastly increased production for those able to master it. But it also threatens those who fail to adopt it with permanent second-class citizenship in the world economy. If an industry cannot lever itself up to the leading stage of technological advances, then it will not be able to compete effectively. I fit cannot do this, no amount of government protectionism or access to foreign markets can keep it profitable for long. Without the profits and experience of technological excellence to reinvest, that industry can only fall still further behind its foreign competitors. So the crux is the technology and that is where the President's program focused. The danger is not that a plan will not be passed, it is that the ideologues of right and left will distort the bill with amendments that will blur its focus on technology. The economic restructuring plan should be passed intact. If we fail to restructure our economy now, we may not get a second chance.
