[填空题]No one knows who the father of the World Wide Web is, except Berners-lee himself.

[单项选择]

Originally, the World-Wide Web was designed as information medium for (71) research teams. A deliberately simple implementation model was chosen to make it as simple as possible for authors to (72) documents to the web, and to (73) these in the sense of updating content. This implementation model is centered around the notion of resources, usually file-base D. For the (74) intended use of the web, resources presented a useful abstraction, as they related to relatively self-contained chunks of information such as research publications and (75) pages. Such chunks of information typically could be set up and maintained independently of other resources, so that resources were the appropriate abstraction for composition and modification.

（71）（）
A. all
B. world
C. distributed
D. internet

Amnesty (大赦) International 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 f
A. representatives from governments, embassies, leading newspapers, etc
B. special people who know the prisoners and their families
C. normal people who have the same views as Amnesty International
D. members of prisoners’ friends or families
