Early life and education[edit] Snow was born 15 March 1813 in York, England. He was the first of nine children born to William and Frances Snow in their North Street home. His neighbourhood was one of the poorest in the city and was always in danger of flooding because of its proximity to the River Ouse. His father worked in the local coal yards, which were constantly replenished from the Yorkshire coalfields through the barges on the Ouse. Snow was baptised at the Anglican church of All Saints, North Street.All Saints, North Street Snow studied in York until the age of 14, when he was apprenticed to William Hardcastle, a surgeon in Newcastle upon Tyne. It was there, in 1831, that he first encountered cholera, which entered Newcastle via the seaport of Sunderland and decimated the town.[1] Between 1833 and 1836 Snow worked as an assistant to a colliery surgeon, first in Burnopfield, County Durham, and then in Pateley Bridge, North Yorkshire. In October 1836 he enrolled at the Hunterian school of medicine on Great Windmill Street, London.[2] Career[edit] In 1837 Snow began working at the Westminster Hospital. Admitted as a member of the Royal College of Surgeons of England on 2 May 1838, he graduated from the University of London in December 1844 and was admitted to the Royal College of Physicians in 1850. In 1850 he was also one of the founding members of the Epidemiological Society of London, formed in response to the cholera outbreak of 1849.[3] In 1857 Snow made an early and often overlooked[4] contribution to epidemiology in a pamphlet, On the adulteration of bread as a cause of rickets.[5] Anaesthesia[edit] Snow was one of the first physicians to study and calculate dosages for the use of ether and chloroform as surgical anaesthetics, allowing patients to undergo surgical and obstetric procedures without the distress and pain they would otherwise experience. He designed the apparatus to safely administer ether to the patients and also designed a mask to administer chloroform.[6] He personally administered chloroform to Queen Victoria when she gave birth to the last two of her nine children, Leopold in 1853 and Beatrice in 1857,[7] leading to wider public acceptance of obstetric anaesthesia. Snow published an article on ether in 1847 entitled On the Inhalation of the Vapor of Ether. A longer version entitled On Chloroform and Other Anaesthetics and Their Action and Administration was published posthumously in 1858.Cholera[edit] Main article: 1854 Broad Street cholera outbreak Original map by John Snow showing the clusters of cholera cases in the London epidemic of 1854, drawn and lithographed by Charles Cheffins.Snow was a sceptic of the then-dominant miasma theory that stated that diseases such as cholera and bubonic plague were caused by pollution or a noxious form of "bad air". The germ theory of disease had not yet been developed, so Snow did not understand the mechanism by which the disease was transmitted. His observation of the evidence led him to discount the theory of foul air. He first publicised his theory in an 1849 essay, On the Mode of Communication of Cholera, followed by a more detailed treatise in 1855 incorporating the results of his investigation of the role of the water supply in the Soho epidemic of 1854.[8] By talking to local residents (with the help of Reverend Henry Whitehead), he identified the source of the outbreak as the public water pump on Broad Street (now Broadwick Street). Although Snow's chemical and microscope examination of a water sample from the Broad Street pump did not conclusively prove its danger, his studies of the pattern of the disease were convincing enough to persuade the local council to disable the well pump by removing its handle. This action has been commonly credited as ending the outbreak, but Snow observed that the epidemic may have already been in rapid decline:There is no doubt that the mortality was much diminished, as I said before, by the flight of the population, which commenced soon after the outbreak; but the attacks had so far diminished before the use of the water was stopped, that it is impossible to decide whether the well still contained the cholera poison in an active state, or whether, from some cause, the water had become free from it.。

3.以“snow”写一篇短文来描述北国冬天美丽的景色
Have you ever seen where the first snow flake folly Is it on the country road, on the branch of an old oak tree, on the wheat fields in the plain, or between the peaks of the mountain range?
See the snowflakes leaping, dancing like flowers in the whirling wind. The flowers have six angles. Sometimes they are like stars. Sometimes they are only white dots, and they keep on falling gently in silence.
Without your knowing it, the fields, houses, trees and the whole earth are enwloped in a thin coat of snow. I love snow, because it is saintly pure.
Winter differs from the other seasons in that it is not as warmag spring, neither as hot as summer, nor as sad as autumn. The snowflake has her own grace and inspiration. It seems tender, yet it is amazingly attractive.
The snowflakes are flying here and there and everywhere. It seems as if they are little stars in the universe moving along their own orbit. Look! What a spotless silvery world, how great, how magnificent!
Away from the crowds of people,I stroll alone in the snow. Standing in the snow, flakes of snow float over my head, kissing me on the cheecks and falling on my eyebrow. Some make their way into my collar and some tall into my mouth. It tastes sweet.
Looking at this silver white world, thoughts well up in my mind. I feel as if I had become a part of them
Some people say snow may bring you joy and happiness. Others think snow can get rid of the dirt in the world. Still others believe snow will purify one's soul, and there are those who hold the view that snow can melt all the evils in its purity and sincerely 。
Oh, snow, you are as pure and white aa the angel in heaven. You come silently and generously protect everything in the world. You melt quietly and nourish a green spring.
Oh, snow, I love you.
