Dear all,

     Please read Professor Hume's email about his next lecture on Rosa Parks.

     Susan Miller

     Secretary.

Dear Susan,

     Please forward this message to students of my history class.

     Besides the life story of Rosa Parks in the textbook, the students are also required to read the passage

below and some related stories that can be borrowed from the school library.

     Ted Hume.

     The early experiences of Rosa Parks (1913-2005), long known as the "mother of the civil rights movement"

were not different from those of many African-Americans at that time. The black woman, however, turned

the course of American history in December 1955 when she refused to give up her seat on a bus to a white

man. "By sitting down," remarked John Lewis, "she was standing up for all Americans."

     Among the numerous awards Parks received in her life were the Presidential Medal of Freedom (1996) and

the Congressional Gold Medal (1999).

     Parks died on Oct. 24, 2005. At St. Paul A. M. E. Church in Montgomery, a large crowd including Secretary

of State Condoleezza Rice celebrated her life. Rice said she and others, who grew up when the political activities

of Parks held public attention, might not have realized her impact (影响) on their lives, "but I can honestly say

that without Mrs. Parks, I probably would not be standing here as Secretary of State."

     After her casket (灵柩) was placed at the Capitol, U.S. President Bush, members of Congress and ordinary

Americans paid their respects. In American history Parks is the first woman to lie in state at the Capitol, a very

high regard usually reserved for Presidents of the United States.
