The Building of the Pyramids
The oldest stone buildings in the world are the pyramids.【46】 There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the "Step" pyramid and the "Bent" pyramid.
Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modem buildings.【47】. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever. 【48】. However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves.【49】. Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly cleat picture of them.
One thing is certain: there must have been months of careful planning before they could begin to build.【50】 You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome.
A. The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.
B. It is practically certain that plans were made for the building of the pyramid because the plans of other large works have fortunately been preserved.
C. The first thing they had to do was to choose a suitable place.
D. Consequently, we are only able to guess at the methods used.
E. Many people were killed while building the pyramids.
F. They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.

Benjamin Disraeli, the famous nineteenth century prime minister, said, "London is not a city, - it is a nation." Today this is an understatementLondon, with its vast range of different ethnic groups, is a world. Certainly, London is the most culturally diverse city in the world. The city was founded by the Romans and since then new arrivals have constantly added to its character and prosperity. Within 10 years 40% of Londoners will be from ethnic minority groups, including the growing number of Londoners of mixed ethnic origin, but most of them will have been born in Britain. Children of Caribbean-Chinese marriages will go to school with children of Russian-Irish couples. None of them will be English but all of them will be Londoners. Most of Britain's ethnic minority residents live in the capital, speaking over 300 languages. Nearly all of the African population and many of the Caribbean population of Britain live in London (83% and 58% respectively)39% of the Chinese population of Britain and 36% of the Asian population of Britain live in London. The largest migrant community is from the Irish Republic with 256,000 people, 3.8% of the total population of London. There are an estimated 330,000 refugees and asylum seekers living in London, with most recent arrivals coming from Eastern Europe, North Africa and Kurdistan. Young people, in particular, are skilled at dealing with a large number of different and hybrid cultures. They themselves often have several different ethnic identities since their parents and grandparents may come from several different backgrounds and their friends and partners do also. They are "skilled cross-cultural travelers" without leaving their home-town.1.Why does the writer think that Benjamin Disraeli's statement is an understatement? Because he thinks London is ().2.

Passage ThreeQuestions 31 to 35 are based on the following passage.One of the most exciting races ever run is now in progress between doctors fighting malaria(疟疾)and mosquitoes. According to the most recent counts 225 million people a year suffer attacks of malaria and more than two million die. Public health workers around the world are doing all t11ev can to destroy malaria before the mosquitoes that pass on the disease become resistant to the poisons now used against them. It's a race against time and against difficulties，with millions of lives in danger and the chances of winning not in man's favour.Malaria，it is true，has been practically wiped out in thirteen countries. including the United States，and is under attack in many others. But it is equally true that in some parts of the world certain types of malaria-carrying mosquitoes have already learned to resist some of the sprays that formerly killed them. Other types of mosquitoes are not killed as quickly by present sprays as they once were.The World Health Organization is helping national governments to get rid of malaria before resistance among the mosquito population becomes so great that new poisons will have to be found to replace those in use at present. Most of the countries in the world have started，or are planning，campaigns against mosquitoes. If the race against resistance is won by man，it is possible that ten years from now dais old evil will have disappeared completely from the America，perhaps from the world.Malaria has been successfully got. rid of in______.A. all countriesB. some countriesC. no countriesD. most countries

回答 68 ~ 71 题： D Liverpool, my hometown, is a unique city.It is so unique that in 2004 it became a World Heritage（遗产）Site.I recently returned to my home city and my first stop was at a museum on the River Mersey.Blanketed in mist（薄雾），Victorian architecture rose from the banks of the river, responded to the sounds of sea-birds, and appeared unbelievably charming.When I headed toward the centre, I found myself surrounded by buildings that mirror the best palaces of Europe.It is not hard to imagine why, on first seeing the city, most visitors would be overpowered by the beauty of the noble buildings, which are solid signs of Liverpool’s history.As if to stress its cultural role, Liverpool has more museums and galleries（美术馆）than most cities in Britain. At Walker Art Gallery, I was told that it has the best collections of Victorian paintings in the world, and is the home of modern art in the north of England． However, culture is more than galleries. Liverpool offers many music events. As Britain’s No.1 music city, it has the biggest city music festival in Europe, and its musicians are famous all over the world.Liverpool is also well-known for its football and other sports events． Every year, the Mersey River Festival attracts thousands of visitors, making the city a place of wonder.As you would expect from such a city, there are restaurants serving food from around the world． When my trip was about to complete, I chose to rest my legs in Liverpool’s famous Philharmonic pub（酒馆）. It is a monument to perfection, and a heritage attraction itself.Being a World Heritage Site , my home city is certainly a place of “outstanding universal value.It is a treasure nouse with plenty of secrets for the world to explore.第13题：Visitors who see the city for the first time would be deeply impressed by________A． its charming banksB． its famous museumsC． its wonderful palacesD． its attractive buildings

“Museum”is a slippery word.It first meant(in Greek)anything consecrated to the Muses:a hill,a shrine,a garden,a
festival or even a textbook.Both Plato’s Academy and Aristotle’s Lyceum had a mouseion,a muses shrine.Although the
Greeks already collected detached works of art,many temples—notably that of Hera at Olympia(before which the Olympic
flame is still lit)—had collections of objects,some of which were works of art by well-known masters,while paintings and sculptures in the Alexandrian Museum were incidental to its main purpose.
The Romans also collected and exhibited art from disbanded temples,as well as mineral specimens,exotic plants,
animals;and they plundered sculptures and paintings(mostly Greek)for exhibition.Meanwhile,the Greek word had slippeD.into Latin by transliteration(though not to signify picture galleries,which were called pinacothecae)and museum still more or
less meant“Muses-shrine”.
The inspirational collections of precious and semi-precious objects were kept in larger churches and monasteries—which
focused on the gold-enshrined,bejewelled relics of saints and martyrs.Princes,and later merchants,had similar collections,
which became the deposits of natural curiosities:large lumps of amber or coral,irregular pearls,unicorn horns,ostrich eggs,
fossil bones and so on.They also included coins and gems—often antique engraved ones—as well as,increasingly,paintings and sculptures.As they multiplied and expanded,to supplement them,the skill of the fakers grew increasingly refined.
At the same time,visitors could admire the very grandest paintings and sculptures in the churches,palaces and castles;
they were not“collected”either,but“site-specific”,and were considered an integral part both of the fabric of the buildings and of the way of life which went on inside them—and most of the buildings were public ones.However,during the revival of
antiquity in the fifteenth century,fragments of antique sculpture were given higher status than the work of any contemporary,
so that displays of antiquities would inspire artists to imitation,or even better,to emulation;and so could be considered Muses-shrines in the former sense.The Medici garden near San Marco in Florence,the Belvedere and the Capitol in Rome were
the most famous of such early“inspirational”collections.Soon they multiplied,and,gradually,exemplary“modern”works were also added to such galleries.
In the seventeenth century,scientific and prestige collecting became so widespread that three or four collectors independently published directories to museums all over the known world.But it was the age of revolutions and industry which produced the next sharp shift in the way the institution was perceived:the fury against royal and church monuments prompted antiquarians to shelter them in asylum-galleries,of which the Musee des Monuments Francais was the most famous.Then,in the first
half of the nineteenth century,museum funding took off,allied to the rise of new wealth:London acquired the National Gallery and the British Museum,the Louvre was organized,the Museum-Insel was begun in Berlin,and the Munich galleries were
built.In Vienna,the huge Kunsthistorisches and Naturhistorisches Museums took over much of the imperial treasure.
Meanwhile,the decline of craftsmanship(and of public taste with it)inspired the creation of“improving”collections.The
Victoria and Albert Museum in London was the most famous,as well as perhaps the largest of them.
The sentence “Museum is a slippery word” in the first paragraph means thatA.the meaning of the word didn’t change until after the 15th century.
B.the meaning of the word had changed over the years.
C.the Greeks held different concepts from the Romans.
D.princes and merchants added paintings to their collections.

Egypt Felled by FamineEven ancient Egypt's mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC.Now evidence gleaned（搜集）from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame-and the same or worse could happen today.The ancient Egyptians depended on the Nile's annual floods to irrigate their crops.But any change in climate that pushed the African monsoons（季风）southwards out of Ethiopia would have diminished these floods.Dwindling（使减少）rains in the Ethiopian highlands would have meant fewer plants to establish the soil.When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt,along with sediment（沉积物）from the White Nile.The Blue Nile mud has a different isotope（同位素）signature from that of the White Nile.So by analyzing isotope differences in mud deposited in the Nile Delta,Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.Krom reasons that during periods of drought,the amount of the Blue Nile mud in the river would be relatively high.He found that one of these periods,from 4,500 to 4,200 years ago,immediately predated the fall of the Egypt's old Kingdom.The weakened waters would have been catastrophic for the Egyptians."Changes that affect food supply don't have to be very large to have a ripple effect in societies,"says Bill Ryan of the Lamont Doherty Earth Observatory（天文台）in New York."Similar events today coald be even more devastating,"says team member Daniel Stanley,a geoarchaeologist from the Smithsonian Institution in Washington, D.0."Anything humans do to shift the climate belts woulld have an even worse effect along the Nile system because the populations have increased dramatically."Which of the following statements is true?A:The White Nile is the trunk of the River Nile.B:The White Nile is the trunk of the Blue Nile.C:The White Nile is a branch of the Blue Nile.D:The White Nile and the Blue Nile are branches of the River Nile.

Earthquake1.Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world.Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results from landslides or major fires which are initiated by the quake.2.There are about a million quakes a year. Fortunately,however,not all of them are destructive.The intensity of an earthquake is measured on the Richter Scale,which goes from 0 upward. The highest scale recorded to date is 8.9.Major damage generally occurs from quakes ranging upwards from 6.0.3.The actual cause of the quake itself is the breaking of rocks at or below the earth's surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth's crust and continental drift.4.In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction.Special instruments are used to help people record,for example,shaking of the earth.Scientists are trying to find methods that will enable them to indicate the exact time,location and size of an earthquake.5.Certain phenomena have been observed which are believed to be signs of imminent earth-quakes.These include strange behaviors of some animals,the changes in the content of mineral water,etc.The magnetic properties of rocks may also display special pattern before major earthquakes happen.Paragraph 2_______.A:Earthquakes forecastB:Historical records of earthquakesC:Intensities of earthquakesD:Cause of earthquakesE:Indications of earthquakes F: Damaging earthquakes

What Makes a Soccer Player Great?Soccer is played by millions of people all over the world,but there have only been few play-ers who were truly great.How did these players get that way—was it through training and prac- tice,or are great players“born,not made”?First,these players came from places that have had famous stars in the past-players that a young boy can look up to and try to imitate.In the history of soccer,only six countries have ever won the World Cup-three from South America and three from western Europe .There has never been a great national team-or a really great player-from North America or from Asia.Second,these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player,as was Pele.Most players begin playing the game at the age of three or four.Finally,many great players come from the same kind of neighborhood—a poor,crowded area where a boy's dream is not to be a doctor,lawyer,or businessman,but to become a rich,famous athlete or entertainer. For example,Liverpool,which produced the Beetles,had one of the bestEnglish soccer teams in recent years.Pele practiced in the street with a“ball”made of rags.And George Best learned the tricks that made him famous by bouncing the ball off a wall in the slums of Belfast.All great players have a lot in common,but that doesn't explain why they are great. Hundreds of boys played in those Brazilian streets,but only one became Pele.The greatest play-ers are born with some unique quality that sets them apart from all the others. According to the author,which of the following statements is true?A: Great soccer players are born,not made.B: Truly great players are rare.C: Only six countries have ever had famous soccer stars.D: Soccer is the least popular sport in North America and Asia.
