Section A

Scientists scanning and mapping the Giza pyramids say they&39;ve discovered that the Great Pyramid of Giza is not exactly even. But really not by much. This pyramid is the oldest of the world‘s Seven Wonders. The pyramid’s exact size has (26) puzzled experts for centuries, as the “more than 21 acres of hard, white casing stones” that originally covered it were (27) removed long ago.

Reporting in the most recent issue of the newsletter “AERAGRAM,” which (28) chronicles the work of the Ancient Egypt Research Associates, engineer Glen Dash says that by using a new measuring approach that involved finding any surviving (29) remnants of the casing in order to determine where the original edge was. They found the east side of the pyramid to be a (30)maximum of 5.55 inches shorter than the west side.

The question that most (31) fascinates him, however, isn&39;t how the Egyptians who designed and built the pyramid got it wrong 4,500 years ago, but how they got it so close to (32) perfect. “We can only speculate as to how the Egyptians could have laid out these lines with such (33) precision using only the tools they had,”Dash writes. He says his (34) hypothesis is that the Egyptians laid out their design on a grid, noting that the great pyramid is oriented only (35) slightly away from the cardinal directions (its north-south axis runs 3 minutes 54 seconds west of due north, while its east-west axis runs 3 minutes 51 seconds north of due east)—an amount that&39;s “tiny, but similar,” Atlas Obscura points out.

A)chronicles

B)complete

C)established

D)fascinates

E)hypothesis

F)maximum

G)momentum

H)mysteriously

I)perfect

J)precision

K)puzzled

L)remnants

M)removed

N)revelations

O)slightly

听力原文: The great advance in rocket theory 40 years ago showed that liquid-fuel rockets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large solid-fuel rockets with solid fuels about as powerful as liquid fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better". The question is meaningless; one might as well as ask whether a gasoline or a diesel engine is "better". It all depends on the purpose. A liquid-fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The burning of the rocket engine can be stopped completely; it can be reignited when desired. A solid-fuel rocket, on the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid-fuel rocket has to be fueled first and can not be held in readiness for very long after it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid-fuel rocket can be kept ready for a long time, most military missiles employ solid fuels, but manned space flight needs the fine adjustments that can only be provided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fuel rocket is, by comparison, cheap.

(33)

A.Neither of the two types of rockets is very economical.

B.The liquid-fuel rocket is best.

C.Each type of rocket has certain advantages.

D.The solid-fuel rocket is best.

第9题
A few years ago, Ann and Walter Taylor thought it might be time to move out of their New Y
ork City apartment to the suburbs. They had one young son and another child on the way. But after months of looking, they became discouraged and decided to buy an old townhouse right in the middle of Brooklyn, which is a part of New York City. To their delight, they discovered that they weren't the only young couple to have made such a decision. In fact, the entire area in Brooklyn had been settled by young families. And as a result, the neighborhood, which had been declining for years, was now being restored.

Brooklyn isn't the only city in the United States to experience this kind of renewal. So are Philadelphia and St. Louis. And Charleston, South Carolina, has so successfully rebuilt its old central area that it now ranks as one of America's most charming cities. The restoration of the old port city of Savannah, Georgia, is also living proof that downtown areas do not need to die. But encouraging as these developments may be, they are among the few bright spots in a mass of difficulties that today's cities face. Indeed, their woes are so many that it is fair to ask whether or not the inner city, the core of most urban areas will manage to survive at all.

In the 1940a, urban Americans began a mass move to the suburbs in search of fresh air, elbowroom, an d privacy. Suburbs began to sprawl out across the countryside. Since most of those making the move were middle-class, they took with them the tax money the cities needed to maintain the neighborhoods in which they had lived. The people left in the cities were often those who were too old or too poor to move. Thus, many cities began to fall into disrepair. Crime began to soar, and public transportation was neglected. (In the past sixty years San Francisco is the only city in the United States to have completed a new mass transit system.) Meanwhile, housing construction costs continued to rise higher and higher. Middle-class housing was allowed to decay, and little new housing was constructed.

Eventually, many downtown areas existed for business only. During the day they would be filled with people working in offices, and at night they would be deserted. Given these circumstances, some business executives began asking, "Why bother with going downtown at all? Why not move the offices to the suburbs so that we can live and work in the same area?" Gradually, some of the larger companies began moving out of the cites, with the result that urban centers declined even further and the suburbs expanded still more. This movement of businesses to the suburbs is not confined to the United States. Businesses have also been moving to the suburbs in Stockholm, Sweden, in Bonn, Germany, and in Brussels, Belgium, as well.

But it may well be that this movement to the suburbs has reached its peak. Some people may be tired of spending long hours commuting, and they may have begun to miss the advantages of culture and companionship provided by city life. Perhaps the decision made by the Taylors is a sign that people will return to the cities and begin to restore them. h begins to look as if suburban sprawl may not have been the answer to man's need to create an ideal environment in which to live and work.

The author of the passage suggests that ______.

A.moving to suburbs is not the answer to an ideal environment

B.cities are likely to be replaced by the suburbs

C.downtown areas are too crowded to live

D.American people moves lot in history

听力原文:Centuries ago, during the Middle Ages, most of the land in Europe was owned by ma

听力原文: Centuries ago, during the Middle Ages, most of the land in Europe was owned by many different kings and queens, princes and princesses, and lords and ladies. They did not all get along. They were always fighting. They all wanted to get more land. To protect themselves, they started building huge homes out of stone. They called their homes castles.

A castle was built behind a strong stonewall. The wall was five or six feet thick and ten to twenty feet high. A deep ditch called a moat was dug around the outside of the wall. It was often filled with water, and the only way anyone could enter the castle was to cross a drawbridge. The drawbridge could be raised or lowered over the moat from inside the castle walls. There was also a tunnel that began in the castle and ended at the moat. This was important in case the castle was captured. It allowed the king and queen to escape. They could swim across the moat and hide in the forest.

Living in a castle was not very comfortable. The rooms were cold and damp. Every room could have a fire burning in a great fireplace, but until the twelfth century castles did not have chimneys. The smoke from their fireplaces had to go out through open doors, and windows.

Meals often had ten or twelve courses. The meat might be wild bears or birds that were boiled or roasted over an open fire. All the food was highly seasoned. People even put pepper in their drinks!

The people sat at a long table and ate with their fingers and a knife, all picking their food from the same big dish. They had no napkins. Therefore, they often wiped their hands on pieces of bread. When their fingers were clean, they threw the bread to their hunting dogs.

(30)

A.Kings and queens, princes and princesses, and lords and ladies built castles in order to get more land.

B.Around the outside of a castle, a moat was dug, which was often filled with water.

C.A castle was built behind a thick and high stonewall, which was strong enough to stand the possible attack of enemies.

D.If a drawbridge was pulled up, there was no way for people to enter the castle.
