factors may weaken one's memory
It
is
often
reported
that
long-term
poor
nutrition
may
affect
the
functioning
of
the
brain,
thus
damaging
both
the
long-term
and
short-term
memory.
Also
harmful
to
one's
memory
is
lack
of
water
.
Elderly
people
need
plenty of water to guarantee their memory works. A third factor is
lack
of sleep
. Without enough sleep, one may feel tired and have difficulty
concentrating, not to mention learning things by heart.
2. Can you describe some possible advantages of having a poor memory
A
poor
memory
may
have
some
advantages.
With
the
passage
of
time,
the
sad
memories
will
fade.
Those
with
a
short
memory
tend
to
recover
faster
than
those
with
a
tenacious
memory.
For
the
same
reason,
forgetful
people
may
be
more
ready
to
forget
their
daily
worries and forgive
others
for
their
offenses
. With a less retentive mind, they may
enjoy life more
.

2. Do you think it is necessary
Some
parents
believe
that
by
doing
a
lot
of
difficult
math
problems,
their
children
will
have
a
solid
foundation
in
math.
Some
parents
even
believe
that
trying
to
solve
hard
math
problems
will
promote
the
growth
of
children's brains and help develop their logical reasoning ability and
concentration, which will facilitate learning in other areas.
On
the
other
hand,
many
people
believe
that
it
is
unnecessary
and
unnatural
for children to study difficult math problems. Some people even believe
that
s
trict
math
training
harms
children's
moral
and
physical
development.
Fierce
competition
may
dampen
the
spirit
of
teamwork,
which
is
so
important in the contemporary world.
4. How to prevent students' cheating in examinations
First, the administrators must adopt
severe measures to punish that
disgraceful
practice.
In
the
case
of
serious
offenders,
it
is
not
enough
just
to
give
them
an
F.
They
must
repeat
the
whole
year,
or
even
be
expelled
from school. Second, it is more important for
teachers to enforce the
university rules strictly
. When they see
students cheating, they should
not turn a blind eye to it.
