Suggested
answers:
Hello
everyone!
Today
I’m
glad
to
share
you
a
great
pioneer
in
agriculture---Yuan
Longping.
It
is
known
to
us
all
that
Yuan
Longing
always
considers
himself
a
farmer.
Actually,
he
is
famous
as
the
“father
of
hybrid
rice”
both
in
China
and
abroad.
What
qualities
make
him
so
successful
is
what
I
will
share
next.
What
impresses
me
most
is
that
he
refused
his
parents’
suggestion
to
study
science
or
medicine
and
received
an
education
at
Southwest
Agricultural
College
in
Chongqing.
What
makes
him
one
of
great
scientists
in
China
is
his
determination
to
tackle
the
crisis
of
the
poor
harvest
and
starvation
of
farmers.
It
is
important
that
he
had
a
dream
to
develop
a
high
output
rice---the
hybrid
rice.
Whether
his
dream
would
be
accomplished
depended
on
his
intense
effort
to
overcome
all
the
difficulties
during
the
research.
It
excited
the
whole
world
that
he
succeeded
in
finding
the
solution
to
boosting
yield
in
the
field.
His
love
and
care
for
his
people
makes
him
beloved.
He
is
devoted
to
circulating
his
knowledge
in
Asia
and
many
less
developed
countries
to
increase
their
harvest
has
been
helping
rid
the
world
of
the
hunger.
That
he
never
gives
up
and
cares
little
about
the
money
and
being
famous
are
his
most
important
qualities.

passage
