根据以下资料,回答13~16题。 Amnesty (大赦) Interational is a world-wide volunteer organization funded entirely by subscriptions and donations.It is totally independent of any government, political faction, ideology, economic interest or religious creed. The organization works for the release of "Prisoners of Conscience" -men, women and children imprisoned anywhere for their beliefs, color, sex, ethnic origin, language or religion.It also seeks fair and immediate trial for all political prisoners detained (拘留) without charge, and opposes torture and the degrading treatment of prisoners.It is also against the death penalty for all types of crime. Amnesty works by collecting information.When it has proof that a person is a " Prisoner of Conscience" , that person's case is handed over to a local group.The local groups are ordinary individuals who believe in Amnesty's work.They send letters to governments, embassies, leading newspapers and the prisoner's family and friends.They also collect signatures and raise money to send medicine, food and clothing to the prisoners and their families.These volunteers use their freedom of speech to win the same freedom for their adopted prisoner.
