(2022·山东泰安第一中学高考模拟)
At
the
age
of
14,
James
Harrison
had
a
major
chest
operation
and
he
required
13
units
(3. 4
gal-
lons)
of
blood
afterwards.
The
blood
donations
saved
his
life,
and
he
decided
that
once
he
turned
18,
he
would
begin
donating
blood
as
regularly
as
he
could.
More
than
60
years
and
almost
1,200
dona-
tions
later,
Harrison,
whose
blood
contains
an
an-
tibody
(抗体)
that
has
saved
the
lives
of
2. 4
mil-
lion
babies
from
miscarriages
(流产),
retired
as
a
blood
donor
on
May
11.
Harrisons
blood
is
valuable
because
he
naturally
produces
Rh-nega-
tive
blood,
which
contains
Rh-positive
antibodies.
His
blood
has
been
used
to
create
anti-D
in
Aus-
tralia
since
1967.
“Every
bottle
of
Anti-D
ever
made
in
Aus-
tralia
has
James
in
it,”
Robyn
Barlow,
the
Rh
program
director
told
the
Sydney
Morning
Herald.
“ Its
an
amazing
thing.
He
has
saved
millions
of
babies.
I
cry
just
thinking
about
it. ”
Since
then,
Harrison
has
donated
between
500
and
800
millili-
ters
of
blood
almost
every
week.
Hes
made
1,162
donations
from
his
right
arm
and
10
from
his
left.
“ Id
keep
going
if
they
let
me,”
Harrison
told
the
Herald.
His
doctors
said
it
was
time
to
stop
the
donations
—
and
they
certainly
dont
take
them
lightly.
They
had
already
extended
the
age
limit
for
blood
donations
for
him,
and
theyre
cut-
ting
him
off
now
to
protect
his
health.
He
made
his
final
donation
surrounded
by
some
of
the
mothers
and
babies
who
his
blood
helped
save.
Harrisons
retirement
