Until recently, the “science of the future” was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the 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 that 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. Clarke, 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 that pollution to catastrophic(灾难性的) 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 that 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(切尔诺贝利), in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.

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)．
