书本知识和经验考研英语作文
generally,
knowledge
gained
from
books
is
theoretical,
that
gained
from experience is practical. it is difficult to
answer which is
more important to we
people. it depends on the phases and events
of our learning.
knowledge learned from books is (instructive
教育性的
,) which
perhaps
cannot
learn
directly
from
experience.
we
often
hear
thunders and see lightning in the sky,
and we can easily find that
lightning
will be seen sooner than sound will be heard.
according to
our
experience
alone,
we
cannot
tell
why
it
had
happened.
but
when we learn some physics
in textbooks, we will find the answer
clearly
that
because
light
travels
faster
than
sound
does,
it
takes
less
time
for
light
to
travel
the
same
distance
than
for
sound.
therefore,
book knowledge can inform us some useful theories
that
can
give
us
general
ideas
and
help
us
understand
the
real
phenomenon better.
in turn, practice knowledge check out the theories gained from
books.
there
is
an
old
chinese
saying
that
practice
is
the
only
criterion of inspecting the truth. so
not all knowledge from books is
credible, even false. when aristotle
wrote in his transcripts that the
earth
is the center of our planets, no one doubts this
for centuries.
