第2题

Knowing that you are paid less than your peers has two effects on happiness. The well-know

n one is negative: a thinner pay packet harms self-esteem. The lesser-known one is called the " tunnel effect" : high incomes for peers are seen as improving your own chances of similar riches, especially if growth, inequality and mobility are high. A paper authored by Tom Dorson of the University of St Andrews separates the two effects using data from household surveys in Germany. Previous work showed that the income of others can have a small, or even positive, overall effect on peoples satisfaction in individual firms. But Mr. Dorsons team hypothesized that older workers, who largely know their lifetime incomes already, will enjoy a much smaller tunnel effect. The data confirm this hypothesis. The negative effect on reported levels of happiness of being paid less than your peers is not visible for people aged under 45. It is only those people over 45, when careers have "reached a stable position" , whose happiness is harmed by the success of others.

听力原文：The Great Fire of London started in the very early hours of September 2nd, 1666.

听力原文： The Great Fire of London started in the very early hours of September 2nd, 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.

The fire started on Sunday morning in the house of the King's baker in Pudding Lane. The baker, with his wife and family, was able to get through a window in the roof. A strong wind blew the fire from the bakery into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.

By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.

People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat. The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.

(33)

A．In a bakery.

B．In a hotel.

C．In a wooden house.

D．In old St Paul's church.

4. Cambridge When we first come across Cambridge in written records, it was already a considerable town. The bridge across the River Cam or Granta, from which the town took its name, had existed since at least 875. The town was an important trading centre before the Domesday survey was compiled in 1086, by which time a castle stood on the rising ground to the north of the bridge, and there were already substantial commercial and residential properties as well as several churches in the main settlement which lay south of the bridge. Within the town, or very close to it, there were a number of other religious institutions. There had been canons in the Church of St Giles below the castle before 1112, when they moved to a new site across the River Cam at Barnwell, and the Convent of St Radegund had existed since 1135 on the site which eventually became Jesus College. There were also two hospitals, one reserved for lepers at Stourbridge, and a second, founded for paupers and dedicated to St John, which after 1200 occupied the site where St John's College now stands. Seventeen miles north of the town was the great Benedictine house of Ely which, after 1109, was the seat of a Bishopric. There was thus much to bring clerks (clergymen) to the town, but traders were also attracted to it. After about 1100 they could reach Cambridge easily by the river systems which drained the whole of the East Midlands, and through Lynn and Ely they had access to the sea. Much wealth accumulated in the town, and the eleven surviving medieval parish churches and at least one handsome stone house remain as evidence of this. There were food markets before 1066, and during the twelfth century the nuns of St Radegund were allowed to set up a fair on their own land at Garlic Lane; the canons of Barnwell had a fair in June (later Midsummer Fair), and the leper hospital was granted the right to hold a fair which developed into the well-known and long-lasting Stourbridge Fair. By 1200, Cambridge was a thriving commercial community which was also a county town and had at least one school of some distinction. Then, in 1209, scholars taking refuge from hostile townsmen in Oxford migrated to Cambridge and settled there. At first they lived in lodgings in the town, but in time houses were hired as hostels with a Master in charge of the students. By 1226 the scholars were numerous enough to have set up an organization, represented by an official called a Chancellor, and seem to have arranged regular courses of study, taught by their own members. From the start there was friction between the town and the students. Students, usually aged about fourteen or fifteen, often caused disturbances; citizens of the town, on the other hand, were known to overcharge for rooms and food. King Henry III took the scholars under his protection as early as 1231 and arranged for them to be sheltered from exploitation by their landlords. At the same time he tried to ensure that they had a monopoly of teaching, by an order that only those enrolled under the tuition of a recognized master were to be allowed to remain in the town. 8. Which of the following is TRUE according to the passage？

A、Cambridge was a big castle in the past.

B、scholars in oxford despised the scholars in Cambridge.

C、King Henry III gave little support to the scholars.

D、There were food markets before 1066.

Visitors to St. Paul's Cathedral are sometimes astonished as they walk round the space und

er the arch to come upon a statue which would appear to be that of a retired armed man meditating upon a wasted life. They are still more astonished when they see under it an inscription indicating that it represents the English writer, Samuel Johnson. The statue is by Bacon, but it is not one of his best works. The figure is, as often in eighteenth-century sculpture, clothed only in a loose robe which leaves arms, legs and one shoulder bare. But the strangeness for us is not one of costume only. If we know anything of Johnson, we know that he was constantly ill all through his life; and whether we know anything of him or not we are apt to think of a literary man as a delicate, weakly, nervous sort of person. Nothing can be further from that than the muscular statue. And in this matter the statue is perfectly right. And the fact which it reports is far from being unimportant. The body and the mind are closely interwoven in all of us, and certainly in Johnson's case the influence of the body was extremely obvious. His melancholy, his constantly repeated conviction of the general unhappiness of human life, was certainly the result of his constitutional infirmities. On the other hand, his courage, and his entire indifference to pain, were partly due to his great bodily strength. Perhaps the vein of rudeness, almost of fierceness, which sometimes showed itself in his conversation, was the natural temper of an invalid and suffering giant. That at any rate is what he was. He was the victim from childhood of a disease which resembled St Vitus's Dance. He never knew the natural joy of a free and vigorous use of his limbs; when he walked it was like the struggling walk of one in irons. All accounts agree that his strange gestures and contortions were painful for his friends to witness and attracted crowds of starers in the streets. But Reynolds says that he could sit still for his portrait to be taken, and that when his mind was engaged by a conversation the convulsions ceased. In any case, it is certain that neither this perpetual misery, nor his constant fear of losing his reason, nor his many grave attacks of illness, ever induced him to surrender the privileges that belonged to his physical strength. He justly thought no character so disagreeable as that of a chronic invalid, and was determined not m be one himself. He had known what it was to live on four pence a day and scorned the life of sofa cushions and tea into which well-attended old gentlemen so easily slip.

Visitors to St Paul's Cathedral are surprised when they look at Johnson's statue because ______.

A．they don't expect it to be there

B．it's dressed in Roman costume

C．it's situated in the dome

D．it's dressed in eighteenth-century costume

How can a single postage stamp be worth $ 16,800？ Any mistake made in the printing of a st

How can a single postage stamp be worth $ 16,800？

Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value.

The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847, an order for stamps was sent to a London printer--Mauritius was to become the fourth country in the world to issue stamps.

(32) Before the order was filled and delivered, a ball was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the several hundred stamps that he printed.

Today there are only 26 of these misprinted stamps left-fourteen One-Penny OrangeReds and twelve Two-penny Blues. Because of the Two-penny Blues' rareness and age, collectors have paid as much as $ 16,800 for it.

A postage stamp's value to collectors is raised if______.

A．there are few others like it

B．there are errors on the stamp

C．a mistake is made in the printing

D．both A and C

听力原文：The Internet is regarded by many as the flagship of global English. According to

a recent survey, English is the medium for more than 80% of the information stored in the world's computers. In many countries, computers have become extensively networked and the networks themselves linked into the global structure of the Internet. The electronic media, such as the Internet, that bind the world together need a common standard to insure speed and proficiency. So the English language becomes the operating standard for global communication. But is it true that the Internet will remain a major driver of the English language？ At present, the language most widely used is English. But this only reflects the fact in the last century, i.e. 90% of the world's computers connected to the Internet are based in English-speaking countries. I think in the 21 st century, the overall shift in Internet use will be similar to that outlined for the economy and the number of computer hosts in Asia will eventually outstrip those in English-speaking countries. Furthermore, the Internet, which used to be a tool for international communication between a global academic elite, has been increasingly serving local, cultural, commercial and educational purposes. And as the Internet becomes more and more widely used, it is natural to expect that a wider range of languages will be employed.

Nowadays, Internet users may have a choice of "language preference" information when they contact a website. If a page is available in that language, it can be retrieved in preference to one in English. This means, for example, that the Web will appear to be in Spanish to a Spanish speaker and in Chinese to a Chinese speaker, provided, of course, the hosts contacted maintain pages in these languages.

What is considered to be the operating standard for global communication？

A．The Internet.

B．The English language.

C．The networked computer.

D．The electronic media.

听力原文： Everybody knows the hamburger is a very popular American food. However, people in the United States learned to make hamburgers from Germans, and Germans got the idea from Russia. In the thirteenth century the Tartar people from central Asia moved into Russia and parts of Europe. They fought the Russians and won. They ate something like hamburger meat but it was raw. This raw meat was beef, goat meat or horse meat. Soon the Russians started to eat raw meat too. Germans from Hamburg and other northern cities learned to eat this food from the Russians. However, they added pepper, a raw egg, and then cooked it. Between 1830 and 1900, thousands of Germans went to live in the United States. They took the hamburger with them. People called it hamburger steak.In 1904o at the World's Fair in St Louis, a city on the Mississippi River, a man from Texas sold hamburger steak in a roll. Then people could eat it with their hands, like a sandwich. This was the first real hamburger like the hamburgers we eat today.Today some people still like to eat raw beef. They call it "steak tartar".

According to the passage, who first had the idea of making hamburgers？

A．Germans.

B．Russians.

C．Americans.

D．Asians.

第11题

In many parts of the world cars play an essential role in daily life and many societies wo

uld cease to function without them. So, tile claim that in 20 years' time, no one will own cars may be hard to believe. But this is tile prediction made by a team of transport researchers who are taken seriously, not only by governments but also by car manufacturers.

The Human Science and Advanced Technology Institute at Loughborough in the U. K. is part of an international research program. The team there believes that by 2020 all cars will be computerized which will mean gigantic fuel savings, no accidents and better use of roads. The super-intelligent car of the 21 st century will drive itself, and it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.

According to Dr. David Davies, who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths' than both world wars put together. Davies says, cars will be fitted with intelligent cruise-con-trol devices to regulate the distance between one car and another. Brakes and accelerators will become redundant(多余的) because the car will automatically speed up, or slow down, to match the speed of the car in front. Computers are much safer drivers than people, so cars and trains will be able to drive much closer together than cars driven by people.

By 2010, David Davies maintains, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead onto the car's windscreen. And, by 2020, cars will travel in convoy, linked to each other electronically. Cars will be connected by an electronically bar to the car in front to form. "road-train". "The front vehicle in such a train," says Davies. "But all the others in the train would burn about ten percent of the normal amount, and so produce about ten percent of the poollution."

We know that governments and car manufacturers______.

A．don't believe the prediction that nobody will own cars by 2020

B．are devoted to the technological innovation in car industry

C．consider the predictions made by the researchers seriously

D．have put the super-intelligent car into mass production
