     About three hundred words in the English language come from the names of people. Many of these words

are technical words. When there is a new invention of discovery, a new word may be coined (杜撰) after the

inventor or scientist.

      It is interesting to observe how many common words have found their way into the language from the

names of people. Lord Sandwich, who lived from 1718-1792, used to sit at the gambling (赌博) table eating

bread with meat in between. As the Lord was the only one among his friends who ate bread in that way, his

friends began to call the bread "sandwich" for fun. Later on,the word became part of the English language.

      The word "boycott" means to refuse to have anything to do with somebody or something. It comes from

a man called Captain Boycott. He was a land agent in 1880 and he collected rents and taxes for an English

landowner in Ireland. But the Captain was a very harsh (苛刻的) man. He treated his poor tenants (佃户) very

badly. His tenants decided not to speak to him at all. Eventually word got back to the landowner and the

Captain was removed (免除). The word "boycott" became popular and was used by everyone to mean the kind

of treatment that was received by Captain Boycott.
