if i had a chance to go to london i'd like to see not only the places of interest but many other interesting things there. certainly everyone knows that the most famous sights of the capital of the great britain are tower bridge over the river themes, big ben, the houses of parliament, trafalgar square, saint paul's cathedral, the british museum, art gallery. it seems i know all these sights well because we have been getting acquainted with them since the 5-th form up to now. i think it will be enough one-day excursion to see all these sights with my own eyes. i'd better visit the one of the numerous english pubs- the local beer halls where englishmen like to spend their free time reading, talking, discussing traditional matters - political, sports and weather over the glass of beer. or i'll try to feel myself as a real englishman visiting a house of a common english family. i'd like to sit round the fire place which is traditional for every english house. if i were lucky i would visit one of the competition or a tournament where traditional english sport games are played - rugby or lawn tennis, horse racing or cricket. i'd like to walk among the students of cambridge or oxford university in their campus and to imagine that i am one of them. i believe my impression on london won't be full if i don't visit madam tussad's museum in baker street. i'm looking forward to seeing their life - size wax portraits of kings and queens, well - known writers, singers and even criminals one of my evenings in london i'd like to spend in a disco club to watch the way english teenagers and young people spare their time, to listen to their popular groups, to make friends and what not.

chemical pollution of atmosphere.the person pollutes atmosphere in the millenia, however consequences of the use of fire which it used all this period, were insignificant. it was necessary to be reconciled by that the smoke disturbed to breath and that soot laid down a black cover on a ceiling and walls of dwelling. received heat for the person was more important, than pure air and incomplete walls of a cave. this initial air pollution did not represent a problem for people lived then small groups, occupying unreasonably extensive untouched environment. and even the considerable concentration of people in rather small territory as it was in a classical antiquity, was not accompanied still by serious consequences.so was up to the beginning of the nineteenth century. only for last hundred years development of the industry "has presented" us with such productions which consequence in the beginning the person could not present itself yet. there were the cities-millionaires which growth it is impossible to stop. all is result of great inventions and gains of the person.the basic polluting substances.basically there are three basic sources of pollution of atmosphere: the industry, household boiler-houses, transport. the share of each of these sources in general, air pollution strongly differs depending on a place. now that most strongly pollutes air industrial production. sources of pollution - thermal power stations which together with a smoke throw out sulphurous and carbonic gas in air; the metallurgical enterprises, especially nonferrous metallurgy which throw out in air оксиды nitrogen, hydrogen sulphide, chlorine, fluorine, ammonia, connections of phosphorus, a particle and connection of mercury and arsenic; chemical and cement works. harmful gases get to air as a result of burning of fuel for needs of the industry, heating of dwellings, work of transport, burning and processing household and industrial wastes.
