第1题

Through a series of experiments, an American scientist has obtained an understanding of th

e social structure of the most complex of ant societies. The ants examined are the only creatures other than man to have given up hunting and collecting for a completely agricultural way of life. In their underground nests they cultivate gardens on soil made from finely chopped leaves. This is a complex operation requiring considerable division of labor. The workers of this type of ant can be divided into four groups according to size. Each of the groups performs a particular set of jobs.

The making and care of the gardens and the nursing of the young ants are done by the smallest workers. Slightly larger workers are responsible for chopping up leaves to make them suitable for use in the gardens and for cleaning the nest. A third group of still larger ants do the construction work and collect fresh leaves from outside the nest. The largest are the soldier ants, responsible for defending the nest.

To find out how good the various size-groups are at different tasks, the scientist measured the amount of work done by the ants against the amount of energy they used. He examined first the gathering and carrying of leaves. He selected one of the size-groups, and then measured how efficiently these ants could find leaves and run back to the nest. Then he repeated the experiment for each of the other size-groups. In this way he could see whether any group could do the job more efficiently than the group normally undertaking it.

The intermediate-sized ants that normally perform. this task proved to be the most efficient for their energy costs, but when the scientist examined the whole set of jobs performed by each group of ants it appeared that some sizes of worker ant were not ideally suited to the particular jobs they performed.

In which way are the ants different from other non-human societies？

A．They do not need to search for food.

B．They do not need to look for shelter.

C．Individuals vary in social status.

D．Individuals perform. different functions.

This was the capitals most anxious week since September 11th. On Monday the government i

ssued a red alert that terrorist attacks were likely in next week, either at home or against American【M1】______ interests abroad. John Ashcroft, the attorney - general, put the security force who guard nuclear power stations and other bits【M2】______ of critical infrastructure on high alert. The warning was grim because it was not issued seriously. Mr.【M3】______ Ashcrofts people are reluctant to worry about an already tense【M4】______ population unnecessarily, particularly as they have no answers to the three main questions: what, when and where They also fret about crying wolf too rarely. Two things persuaded them to go public: an unusual【M5】______ volume of talk about a forthcoming "big event" emanated from various【M6】______ terrorist enclaves, and the consistent use of an unrevealed codeword. The warning came amid yet more dire news about anthrax. A swathe of federal buildings and the Supreme Court have now infected【M7】______ with the stuff. On October 31, a New York hospital worker died for【M8】______ inhalation anthrax, bringing the number of deaths to four. She had had no contact with government or media post-rooms, so the disease seems to have infected the general mail. Anthrax has turned out in two local【M9】______ post offices in Washington. People have taken to tape up their letter【M10】______ boxes and asking postal workers to leave the letters outside. Add in the frustrating news from Afghanistan, and the exhilaration that swept through the capital after Americas decision to "strike back at terror" has now evaporated. Of course, reverses in any war are inevitable.

听力原文：In the high mountain country outside the city of Toluker, there stands a prison.

听力原文： In the high mountain country outside the city of Toluker, there stands a prison. This prison is quite different from other prisons in the world. The guards, except for two at the main gate, are not armed. There are many remarkable things about Toluker prison. For example, of the 15, 000 individuals who have been in prison at Toluker, less than two percent have got into trouble again with the law. Men in the open prison are free to find work on the outside but must go back to prison each night. On weekends they are allowed to go home. When most other prisons are still sending criminals back into society. Toluker is returning people who stand on their own feet and contribute to society. In 1970, a prisoner called Barb Crook moved to the open prison. A year later, he left Toluker for the last time. He was then nearly forty six and had been in prison for fourteen years. He got a job as construction worker in the city, remarried and was regarded as a useful person of his community, ff you ask Bob why Toluker works, he would say "Because they believed in me when I was at my worst."

(30)

A．The prison gates always open.

B．Its prisoner can work outside.

C．The prison has no armed guards.

D．The prison is open to the public.

第8题

Many American presidents in the 19th century were born in poor families. They spent their

childhood in little wooden rooms. They got little education. Washington and Lincoln, for example, never went to school and they taught themselves. Lincoln once did jobs of a worker, shopkeeper and postmaster in his early years.

A large number of American presidents had experiences in the army. The two best known were Ulysses Grant and Dwight Eisenhower. Grant was a general in the American Civil War and Eisenhower was a hero in the Second World War. It happened that they graduated from the same school— West Point Military Academy (西点军校). One may be surprised to learn that both of them did not do well in the school. Eisenhower, for example, was once fined because he broke the roles of the school.

The jobs of the US president are tiring. He must keep an eye on anything important which happens both at home and abroad. Every day, a lot of work waits for him to do and he has to make many important decisions. When Franklin Roosevelt was a child, he was once brought to visit President Taft. The old president said to him, "When you grow up you should not be the president. It's a tiring job."

According to the passage, who regarded the jobs of the US president as tiring ones？

A．Grant.

B．Taft.

C．Eisenhower.

D．Roosevelt.

第9题

Despite a cooling of the economy, high technology companies are still crying out for skill

ed workers. The Information Technology Association of America projects that more than 800,000 technology jobs will go unfilled next year. The lack of qualified workers poses a huge threat to the US economy.

The most commonly cited reason for this state of affairs is that the countrys agrarian-age education system, separated from the needs of the business world, fails to prepare students in the primary and secondary grades for twenty-first-century work. Yet an inadequate and outmoded education system is only part of the problem. A less tangible but equally powerful cause is an antique classification system that divides the workforce into two camps: white-collar knowledge workers and blue-collar manual labourers.

Blue-collar workers emerged in the United States during the Industrial Age as work migrated from farms to factories. White-collar office workers became a significant class in the twentieth century, outnumbering their blue-collar brethren by mid-century. But the white or blue paradigm has clearly outlived its utility. Corporations increasingly require a new layer of knowledge worker: a highly skilled multi-disciplinarian who combines the mind of the white-collar worker with the hands of the blue-collar employee. Armed with a solid grounding in mathematics and science(physics, chemistry, and biology), these "gold-collar" workers — so named for their contributions to their companies and to the economy, as well as for their personal earning ability — apply that knowledge to technology. Of course, the gold-collar worker already exists in a wide range of jobs across a wide range of businesses: think of the maintenance technician who tests and repairs aircraft systems at American Airlines; the network administrator who manages systems and network operations at P&G; the advanced-manufacturing technician at Intel.

But until American business recognises these people as a new class of worker, one whose collar is neither blue nor white, demands that schools do a better job of preparing employees for the twenty-first-century workforce will be futile.

What effects may the insufficiency of qualified workers have, according to the passage？

A．It decreases the costs of high technology companies.

B．It emphasises the importance of unfilled jobs.

C．It hinders the development of the US economy.

D．It accelerates the collapse of the old education system.
