Use of digital libraries is increasingly common.
It is important that the cost of disk accesses be reduced in query processing.
Such openings succeed in establishing context but fail in motivation, often because
they are an assertion that a reasonable person might disagree with. A simpler or more
specific statement may well be preferable.
Digital libraries provide fast access to large numbers of documents.
Query processing can involve many disk accesses.
A typical organization for the introduction of a paper is to use the first paragraphs
to describe the context. It is these paragraphs that convince the reader that the paper
is likely to be interesting. The opening sentences should clearly indicate the topic.
Underutilization of main memory impairs the performance of operating
systems.
Operating systems are traditionally designed to use the least possible amount
of main memory, but such design impairs their performance.
The second version is better for several reasons. It is clear; it states the context, which
can be paraphrased as operating systems don't use much memory ; and, in contrast to
the first version, it is positive.
Take care to distinguish description of existing knowledge from the description
of the paper's contribution.
Many user interfaces are confusing and poorly arranged. Interfaces are
superior if developed according to rigorous principles.
Many user interfaces are confusing and poorly arranged. We demonstrate that
interfaces are superior if developed according to rigorous principles.
In most papers, the introduction should not flow on from the abstract, which is a
summary of a paper rather than its opening. The paper should be complete even with
the abstract removed.

Diversity—in organization, structure, length of sentences and paragraphs, and word
choice—helps to keep the reader's attention.
The system of rational numbers is incomplete. This was discovered
2000 years ago by the Greeks. The problem arises in squares with sides
of unit length. The length of the diagonals of these squares is irrational.
This discovery was a serious blow to the Greek mathematicians.
