нужно прочитать текст. мне нужно прочитать на русском....John Edgar Hoover was born in 1885. He was a native of Washington, D.C. He went to school there and then to George Washington University where he studied law. As a student he was a brilliant one and had a great choice after graduating from the University.
2. John Hoover got a Job in the Department of Justice. Very soon he was sent to the Federal Bureau of Investigations. That was in 1924 when J.E. Hoover was forty.
3. The FBI was created primarily to handle criminal investigations. Now it handles over 180 different kinds of investigations and its responsibilities are growing. Squads of highly trained FBI Agents are devoting their efforts to fighting against organized crime.
4. For many years John Hoover was the head of the FBI and made it world's greatest law enforcement organization. He opened a technician and scientific laboratory, an identification division; set up a lot of training schools. He was also the initiator of National Police Academy where he taught as the chief instructor.
5. John Hoover had a photographic mind: he called agents by their first names. He remembered all investigations and their results. He said "The main task of the FBI is the protection of people against crime".
6. As to his personal life he had no time to get married. When he was not busy with his service in FBI, he usually went fishing or hunting. Hoover played tennis very well. He also liked music.
