Task 3 Spot Dictation
Listen to a passage three times and
while listening, you are
to put the
missing word in each numbered blank according
to what you hear.
Experts
say
water
is
important
for
many
reasons.
Between fifty-five and seventy-five
percent of the body is
6
water. Water in blood carries (1)
hormones
and antibodies
through
the
body.
Water
in
urine
carries
away
waste
materials. Water is
needed for (2)
cooling
the
body on hot
days,
and
when
we
are
working
or
exercising.
Water
carries body heat to the surface of the
skin. There, the heat
is lost through
(3)
perspiration
.
Health
experts
say
adults
should
drink
about
two
liters of water a day to (4)
replace
all the water lost
in liquid
wastes
and
perspiration.
They
say
people
should
drink
more than that in hot
weather.
Experts say it is important to
drink before, during and
after
(5)
exercise
.
They
say
we
should
drink
water
even
before
we
start
to
feel
like
we
need
something
to
drink.
During
hot
weather,
cool
liquids
are
best.
Also,
(6)
avoid
sweet
drinks and alcohol.
We need to add that
doctors also say it is possible to
drink too much water. Some people, for
example, do this if
they exercise hard
during a (7)
heat
wave.
Experts with the
Mayo
Clinic
say
drinking
too
much
water
can
cause
hyponatremia. In this
condition, the level of (8)
sodium
in
the
blood falls too low.
The
result
is
that
the
amount
of
water

the
body
