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．as good as wool B．as 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. The name England comes from the words “Angle land”．The Angles were people who came from northern Germany in the 5th and 6th centuries，after the Romans had left.The French name for England is Angleterre，which also means “Angle land”．There were also invasions (侵略) of southern England by Saxons and Jutes (people from another part of northern Germany)．English people are sometimes called AngloSaxons.The Celts who used to live in this area were forced to move back into Scotland，Ireland，Cornwall and into Western France (the area known as Brittany)．
England at first became a series of kingdoms，the strongest of which was Wessex (the name comes from WestSaxon)．The names of many of the areas in England come from this period—for example，the name Sussex comes from SouthSaxon，Essex from EastSaxon，and East Anglia from EastAngle.The Vikings then came from Denmark，and later the Normans invaded from France. Eventually England，Wales，Scotland and Northern Ireland were united，forming the United Kingdom.
The English language is the main language spoken throughout England，although there are many different accents.It can be difficult to know how to spell or to pronounce some English words，because the language has been influenced by Latin and Greek (languages used at the time of the Romans，and used in religion and education until recent times)，German (the language of the Angles，Saxons and Jutes)，French(the language of the Normans)，Gaelic/Scots (Celtic languages) and Danish (the language of the Vikings)．
There are now many people throughout the United Kingdom who speak a foreign language either as their first or second language；mainly due to immigration (移民) from Europe or the Commonwealth (countries which used to be part of the British Empire)．
【小题1】According to the first paragraph，which of the following statements is NOT true?
| A．The Romans were forced to leave England when the Jutes attacked there. |
| B．The Celts used to live in England but left for some reason. |
| C．Southern England once was attacked by Saxons and Jutes. |
| D．Angles and Saxons came from different parts of northern Germany. |
| A．Sussex | B．Wessex |
| C．Essex | D．East Anglia |
| A．English words are hard to spell and to pronounce. |
| B．England had been invaded by most of the countries of Europe. |
| C．The English language was influenced by several foreign languages. |
| D．It’s hard for people who have different English accents to communicate. |
| A．Because they are required to learn a foreign language at school. |
| B．Because they plan to live outside the UK in the future. |
| C．Because they have moved from other countries. |
| D．Because they have worked in other countries. |
| A．tell the history of England |
| B．tell how the United Kingdom was formed |
| C．introduce the main spoken language throughout England |
| D．tell the origin of the name of England |
Roman Pantheon （万神殿） 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(圆顶). 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 (坟场) 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.
