years

said②
a
Chinese
ruler
called

was
the
first
to
discover
tea
as
a
drink.
One
day
Shen
Nong
was
boiling
drinking
water
over
an
open
fire.
Some
leaves
from
a
tea
plant
fell
into
the
water
and
remained
there
for
some
time.
It
produced
a
nice
smell
so
he
tasted
the
brown
water.
It
was
quite
delicious,
and
so,
one
of
the
world’s
favorite

A
few
thousand
years
later,
Lu
Yu,
“the
saint
of
tea”,
mentioned
Shen
Nong
in
his
book
Cha
Jing.
The
book
describes
how
tea
plants
were
grown
and
used
to
make
tea.
It
also
discussed
where
the
finest
tea
leaves
were
produced
and
what
kinds
of
water
were
used.

It
is

was

and

In
England,
tea
didn’t
appear
until④
around
1660,
but
in
less
than
100
years,
it
had
become
the
national
drink.
The
tea
trade
from
China
to
Western
countries
took
place⑤
in
the
19th
century.

Even
though
many
people
now
know
about

culture,
the
Chinese
are
without
doubt
the
ones
who
best
understand
the
nature
of
tea.

用法
示例
3.含双宾语和复合宾语的主动句变为被动语
态的方法
①
含有双宾语的主动句变为被动语态时，通常把
指
“人”的间接宾语变为主语，而指“物”的
直接宾语则不变
He
gave
me
a
book
yesterday.
I
was
given
a
book
(by
him)
yesterday
②
如果要把指“物”的直接宾语变为主语，则在
间接宾语前加to或for。
I
brought
him
some
food.
Some
food
was
brought
to
him
(by
me).
③
含有复合宾语的主动句变为被动语态时，要将
其中的宾语变成主语，宾语补足语不变。
Jim
asked
Tom
to
go
for
a
walk.
Tom
was
asked
(by
Jim)
to
go
for
a
walk.
④
如果宾语补足语是不带to的动词不定式，主动
语态变成被动语态时要加上不定式符号
to。
