  London Smog  For hundreds of years, the mists and fogs of Britain's major cities were

  all too often polluted and noxious, with London especially badly affected. The

  fogs endangered health and also posed a threat to travelers who lost their way

  and thus became an easy prey to robbers. Around 1807, the smoke-laden fog of the

  capital came to be known as a 'London particular', i.e. a London characteristic.

  Charles Dickens used the term in Bleak House (published in 1853) and provided

  graphic descriptions of London's fogs in this and other novels.  The smoke-laden fog that shrouded the capital from Friday 5 December to

  Tuesday 9 December 1952 brought premature death to thousands and inconvenience

  to millions. An estimated 4,000 people died because of it, and cattle at

  Smithfield, were, the press reported, asphyxiated. Road, rail and air transport

  were almost brought to a standstill and a performance at the Sadler's Wells

  Theatre had to be suspended when fog in the auditorium made conditions

  intolerable for the audience and performers.  The death toll of about 4,000 was not disputed by the medical and other

  authorities, but exactly how many people perished as a direct result of the fog

  will never be known. Many who died already suffered from chronic respiratory or

  cardiovascular complaints. Without the fog, they might not have died when they

  did.  The total number of deaths in Greater London in the week ending 6 December

  1952 was 2,062, which was close to normal for the time of year. The following

  week, the number was 4,703. The death rate peaked at 900 per day on the 8th and

  9th and remained above average until just before Christmas. Mortality from

  bronchitis and pneumonia increased more than sevenfold as a result of the fog.

  The fog of December 1952 was by no means the first to bring death and

  inconvenience to the capital. On 27 December 1813 fog was so dense that the

  Prince Regent, having set out for Hatfield House, was forced to turn back at

  Kentish Town. The fog persisted for almost a week and on one day was so thick

  that the mail coach from London to Birmingham took seven hours to reach

  Uxbridge. Contemporary accounts tell of the fog being so thick that the other

  side of the street could not be seen. They also tell of the fog bearing a

  distinct smell of coal tar. After a similar fog during the week of 7-13 December

  1873, the death rate in the Administrative County of London increased to 40 per

  cent above normal. Marked increases in death rate occurred, too, after the

  notable fogs of January 1880, February 1882, December 1891, December 1892 and

  November 1948. The worst affected area of London was usually the East End, where

  the density of factories and domestic dwellings was greater than almost anywhere

  else in the capital. The area was also low-lying, which inhibited fog

  dispersal.  In early December 1952, the weather was cold, as it had been for some

  weeks. The weather of November 1952 had been considerably colder than average,

  with heavy falls of snow in southern England towards the end of the month. To

  keep warm, the people of London were burning large quantities of coal in their

  grates. Smoke was pouring from the chimneys of their houses and becoming trapped

  beneath the inversion of an anticyclone that had developed over southern parts

  of the British Isles during the first week of December. Trapped, too, beneath

  this inversion were particles and gases emitted from factory chimneys in the

  London area, along with pollution which the winds from the east had brought from

  industrial areas on the continent.  Early on 5 December in the London area, the sky was clear, winds were light

  and the air near the ground was moist. Accordingly, conditions were ideal for

  the formation of radiation fog. The sky was clear, so a net loss of long-wave

  radiation occurred and the ground cooled. The moist air in contact with the

  ground cooled to its dew-point temperature and condensation occurred. Cool air

  drained katabolically into the Thames Valley. Beneath the inversion of the

  anticyclone, the very light wind stirred the saturated air upwards to form a

  layer of fog 100-200meters deep. Along with the water droplets of the fog, the

  atmosphere beneath the inversion contained the smoke from innumerable chimneys

  in the London area and farther afield. Elevated spots such as Hampstead Heath

  were above the fog and grime. From there, the hills of Surrey and Kent could be

  seen. During the day on 5 December, the fog was not especially dense and

  generally possessed a dry, smoky character. When nightfall came, however, the

  fog thickened. Visibility dropped to a fewmeters. The following day, the sun was

  too low in the sky to make much of an impression on the fog. That night and on

  the Sunday and Monday nights, the fog again thickened. In many parts of London,

  it was impossible at night for pedestrians to find their way, even in familiar

  districts. In the Isle of Dogs, the visibility was at times nil. The fog there

  was so thick that people could not see their own feet! Even in the drier

  thoroughfares of central London, the fog was exceptionally thick. Not until 9

  December did it clear. In central London, the visibility remained below

  500meters continuously for 114 hours and below 50meters continuously for 48

  hours. At Heathrow Airport, visibility remained below ten meters for almost 48

  hours from the morning of 6 December.  Huge quantities of impurities were released into the atmosphere during the

  period in question. On each day during the foggy period, the following amounts

  of pollutants were emitted: 1,000 tonnes of smoke particles, 2,000 tonnes of

  carbon dioxide, 140 tonnes of hydrochloric acid and 14 tonnes of fluorine

  compounds. In addition, and perhaps most dangerously, 370 tonnes of sulphur

  dioxide were converted into 800 tonnes of sulphuric acid. At London's County

  Hall, the concentration of smoke in the air increased from 0.49 milligrams per

  cubic meter on 4 December to 4.46 on the 7th and 8th.  Legislation followed the Great Smog of 1952 in the form of the City of

  London (Various Powers) Act of 1954 and the Clean Air Acts of 1956 and 1968.

  These Acts banned emissions of black smoke and decreed that residents of urban

  areas and operators of factories must convert to smokeless fuels. As these

  residents and operators were necessarily given time to convert, however, fogs

  continued to be smoky for some time after the Act of 1956 was passed. In 1962,

  for example, 750 Londoners died as a result of a fog, but nothing on the scale

  of the 1952 Great Smog has ever occurred again.

  关于机经训练,浅尝辄止,非正道也,考生的发音、文笔以及流畅度,都不会因为仅知道这个话题而改变。写作必须分析范文思路和学习词汇句法句型之后反复复盘纠错。也希望此份详尽的预测机经能够让考生早日与雅思君分手
