Originally, the World-Wide Web was designed as information medium for（71) research teams.

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-based. 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.
