单项选择题

An essay which appeals chiefly to the intellect is
Francis Bacon’s "Of Studies." His careful tripartite
division of studies expressed succinctly in apho-
Line ristic prose demands the complete attention of the
(5) mind of the reader. He considers studies as they
should be: for pleasure, for self-improvement, for
business. He considers the evils of excess study:
laziness, affectation, and preciosity. Bacon divides
books into three categories: those to be read in
(10) part, those to be read cursorily, and those to be
read with care. Studies should include reading,
which gives depth; speaking, which adds readiness
of thought; and writing, which trains in precise-
ness. Somewhat mistakenly, the author ascribes
(15) certain virtues to individual fields of study: wis-
dom to history, wit to poetry, subtlety to mathe-
matics, and depth to natural philosophy. Bacon’s
four-hundred-word essay, studded with Latin
phrases and highly compressed in thought, has
(20) intellectual appeal indeed.
