Until recently, the "science of the future" was supposed to be electronics and artificial intelligence．Today it seems more and more likely that me next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering．This combination is the science of biotechnology．

Organic chemistry enables us to produce marvelous synthetic（合成的）materials．However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture．Nothing mat we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects．

Nevertheless, scientists in the, laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin．The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings．These will not be rejected by the body, as is the case with organs from humans．

The application of biotechnology to energy production seems even more promising．In 1996 the famous science fiction writer, Arthur C．Clarice, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy．Some of these power sources will be biological．Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources．Coal, oil and gas are indeed convenient．However, using them also means creating dangerously high levels of pollution．It will be impossible to meet the growing demand for energy without increasing mat pollution to catastrophic levels unless we develop power sources that are both cheaper and cleaner．

It is attempting to think that biotechnology or some other "science of the future" can solve our problems．Before we surrender to（屈服于） mat temptation we should remember nuclear power．

Only a few generations ago it seemed to promise limitless, cheap and safe energy, today those promises lie buried in a concrete grave in a place called Chernobyl, in me Ukraine．Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way．

50．According to the passage, the science of the future is likely to be_____．

　　　 A．electronics　 　 　　　　　　　　　　　　　　　　　　　 B．biotechnology　 　

　　　 C．genetic engineering　 　　　　　　　　　　　 　　　 D．nuclear technology

51．Organic chemistry helps to produce materials mat are_____．

　　　 A．a(chǎn)s good as wool　　　　　　　 　　　　　　　 B．a(chǎn)s good as an insect's body

　　　 C．not as good as natural materials　　 　　　　　 D．better than natural material

52．According to the passage, it may soon be possible_____．

　　　 A．to make something as good as human skin 　 B．to produce drugs without side effects

　　　 C．to transplant human organs　　　　 　　　 D．to make artificial hearts and eyes

53．In 1996．Arthur C．Clarke predicted that _____．

　　　 A．biological power sources would be put into use soon

　　　 B．oil, gas and coal could be repeatedly used in the future

　　　 C．dependence on non-renewable power sources would be reduced soon

　　　 D．the Chemobyl disaster would happen in two years

54．What do we leam from the last paragraph?

　　　 A．Biotechnology can solve all our future energy problems．

　　　 B．Biological power is cheaper than nuclear power．

　　　 C．Biological power may not be as dangerous as nuclear power．

　　　 D．Biological power will keep all its promises．

At the bottom of the world lies a mighty continent still wrapped in the Ice Age and, until recent times, unknown to man. It is a great landmass with mountain ranges whose extent and elevation are still uncertain. Much of the continent is a complete blank on our maps. Man has explored, on foot, less than one percent of its area.

Antarctica differs fundamentally from the Arctic regions. The Arctic is an ocean, covered with drifting packed ice and hemmed in by the landmasses of Europe, Asia, and North America. The Antarctica is a continent almost as large as Europe and Australia combined, centered roughly on the South Pole and surrounded by the most unobstructed water areas of the world—the Atlantic, Pacific, and Indian Oceans.

The continental ice sheet is more than two miles high in its center; thus, the air over the Antarctica is far more iced than it is over the Arctic regions. This cold air current from the land is so forceful that it makes the nearby seas the stormiest in the world and makes unlivable those regions whose counterparts (配對物) at the opposite end of the globe are livable. Thus, more than a million persons live within 2, 000 miles of the North Pole in an area that includes most of Alaska, Siberia, and Scandinavia—a region rich in forest and mining industries. Apart from a handful of weather stations, within the same distance of the South Pole there is not a single tree, industry or settlement.

66. The best title for this passage would be________ .

A. Iceland

B. Land of Opportunity

C. Utopia at Last

D. The Unknown Continent

67. At the time this article was written, our knowledge about Antarctica was______.

A. very limited                                                 B. vast

C. fairly rich                                                    D. non-existent

68. What’s the fundamental difference between Antarctica and the Arctic?

A. The Arctic is an ocean while Antarctica is a continent.

B. The Arctic is inhabited by people while Antarctica is uninhabitable.

C. The Arctic is covered with ice while Antarctica is surrounded by water.

D. The Arctic is surrounded by continents while Antarctica is bordered by oceans.

69. The Antarctica is made uninhabitable primarily by________.

A. ice                                                                     B. calm seas

C. cold air                                                              D. lack of water

70. According to this article,________ .

A. 2, 000 people live on the Antarctica Continent

B. a million people live within 2, 000 miles of the South Pole

C. weather conditions make settlements impractical

D. only a handful of natives inhabit Antarctica

 Roman Pantheon （萬神殿） is one of the greatest achievements of the ancient Romans. The ancient Romans were good architects and they built many wonderful buildings. Another good example of a Roman architectural style is the Roman Coliseum, which is a large building used for public sports events or entertainment. The Roman architectural style has been borrowed by many of the western countries.
The architecture of Pantheon is unique to Rome. In Latin and Greek, pantheon means "Temple of all the Gods". Marcus Agrippa built the original Pantheon in 27 BC. But the Pantheon built by Agrippa was completely destroyed in 80 AD when a fire broke out. The Roman Pantheon that is visited by many tourists today was rebuilt in 125 AD by the Roman emperor Hadrian. Hadrian's architects followed the exact design of Marcus Agrippa. Historians believe that the Pantheon was a place of worship(崇拜) because it housed all the gods and goddesses of the ancient Romans.
The Pantheon of Rome is an amazing example of ancient Roman architecture. This building has been in use for over 2000 years. The Roman Pantheon is famous for its design, size. The most unbelievable feature of this building is its huge concrete dome(圓頂). The Pantheon’s dome was thought to be the largest, until recent times.
Phocas, the Byzantine Emperor presented the Roman Pantheon to Pope Boniface IV to save it from the destruction. In 609 AD, it was turned into a church. During Papal rule, it was used as a burial ground (墳場) for kings and other famous people. There are tombs of Raphael (a painter), King Victor Emmanuel II, King Umberto I and many more in the Pantheon.
Some of the buildings that were constructed on the model of the Roman Pantheon are The Rotunda - University of Virginia, Low Memorial Library - Columbia University, Grand Auditorium - Tsinghua University, Jefferson Memorial - Washington D.C. and Duomo - Florence.
