英语六级阅读理解
The English policeman has several nicknames ( 绰号 ) but the most frequently used are "copper" and "bobby". The first name comes from the verb "to cop " (which is also slang ) , meaning " to take " or " to capture ", and the second comes from the first name of Sir Robert Peel, the nineteenth-century politician, who was the founder of the police force as we know it today. An early nickname for the policeman was "peeler", but this one has died out.
