四、语法选择。
Have
you
heard
of
Mona
Lisa?
Mona
Lisa
was
one
of
__11__
paintings
in
the
world.
It
was
created
by
Leonardo
da
Vinci.
He
was
a
great
artist
and
__12__
a
great
scientist.
He
thought
that
science
depends
__13__
people's
understanding
of
nature.
He
always
kept
it
in
mind,
__14__
he
studied
everything
about
nature
and
human.
Leonardo
always
believed
in
__15__
the
knowledge
of
science
into
practical
use.
And
he
did
__16__
experiments
to
explore(探索)
nature
and
human.
Leonardo
had
lots
of
inventions,
but
__17__
of
them
were
put
to
use.
That
was
because
once
he
came
up
with
__18__
idea,
he
rushed
to
the
next
one.
But
luckily,
he
would
write
his
ideas
down
on
notebooks.
So
we
__19__
know
about
his
inventions
from
his
detailed(详细的)
notebooks.
Leonardo
called
science
“the
knowledge
of
the
future,
the
present
and
the
past”，
and
he
wanted
__20__
all
the
three.
In
the
fifteenth
century,
understanding
the
science
of
the
past
became
__21__
than
before
with
the
invention
of
the
printing.
He
__22__
his
best
to
study
the
science
of
the
past
and
made
some
achievements.
Through
__23__
efforts,
Leonardo
improved
the
science
at
that
time.
His
thoughts
and
inventions
played
an
important
role
to
the
future.
Before
the
invention
of
the
telephone
and
radio,
he
wrote
__24__
men
from
the
far
countries
may
talk
to
one
another,
and
share
their
ideas
with
each
other
easily.
So
people
thought
that
__25__
all
of
Leonardo's
scientific
achievements
could
be
published(出版)
at
that
time,
the
world's
science
would
go
forward
30
to
50
years.
