Grammar
The
General
Idea
of
This
Period
This
is
the
fifth
period,
which
will
center
on
the
grammar:
using
the
past
participle
as
the
attribute
and
the
predicative.
At
the
beginning
of
this
period,
the
teacher
should
give
the
students
some
time
to
go
over
what
they
learned
in
the
last
period.
Later
the
teacher
had
better
present
some
sentences
containing
the
past
participle
used
as
the
attribute
and
the
predicative
on
purpose
by
asking
the
students
to
do
some
exercises.
Get
the
students
to
find
all
the
sentences
containing
the
past
participle
in
the
two
passages.
After
finding
them,
the
teacher
can
ask
the
students
to
analyze
them
and
understand
the
function
of
the
past
participle
in
those
sentences.
After
that
the
teacher
should
give
the
students
clear
explanations
about
the
usage
of
the
grammar.
After
mastering
the
rules
of
the
past
participle,
the
students
should
be
given
more
exercises
to
consolidate
what
they
learn.
The
teacher
should
arrange
some
activities
carefully
and
creatively.
First
let
them
do
some
simple
exercises.
For
example,
combine
the
two
sentences
using
the
past
participle
as
the
attribute
and
the
predicative.
Then
ask
them
to
make
some
sentences
using
the
past
participle.
Besides
that,
the
teacher
should
help
the
students
to
review
the
other
usages
of
the
past
participle.
In
the
end,
let
them
write
a
passage
using
the
past
participle
properly.
Apart
from
the
usage
of
the
past
participle,
the
teacher
had
better
make
the
students
understand
the
differences
between
the
past
participle
and
the
present
participle.
In
order
to
have
the
students
master
it,
the
teacher
should
choose
some
exercises
to
supply
the
students
with
some
problems
to
deal
with.
By
doing
and
practicing
more,
the
students
may
master
the
grammar.

Procedure

Greeting
T:
Hello,
my
friends.
Ss:
Hello,
Miss...
Step

Revision
T:
Do
you
still
remember
what
you
learned
in
this
unit?
Would
you
please
say
something
about
the
great
scientists
we
learned
in
this
unit.
First
please
something
about
John
Snow.
S:
John
snow,
a
well-known
doctor
in
London,
defeated
cholera.
S:
He
got
interested
in
two
theories
explaining
how
cholera
killed
people.
S:
John
Snow
gathered
the
information
and
marked
it
on
a
map
where
all
the
dead
people
had
lived.
S:
He
discovered
that
many
of
the
deaths
were
near
the
water.
It
seemed
the
water
was
to
blame.
Ss:
...
T:
You
really
did
a
very
good
job.
Now,
let’s
say
something
about
Nicolaus
Copernicus.
S1:
Nicolaus
Copernicus
believed
that
the
earth
is
not
the
centre
of
the
solar
system.
But
at
that
time
people
all
believed
God
had
made
the
world
and
for
that
reason
the
earth
was
special
and
must
be
the
centre
of
the
solar
system.
S2:
In
1514
he
showed
his
theory
privately
to
his
friends
and
explained
his
theory.
S3:
He
was
very
cautious
because
he
did
not
want
to
be
attacked
by
the
Christian
church.
S4:
He
published
his
theory
as
he
lay
dying
in
1543.
S5:
His
theory
was
rejected
by
the
Christian
Church.
Step

Presentation
T:
Today
we
will
learn
the
grammar—past
participle
used
as
the
attribute
and
the
predicative.
First
look
at
your
text
on
Page
4,
part
I.
Look
at
the
following
sentences
where
the
past
participles
are
used.
T:
In
this
sentence
the
past
participle
is
used
as
an
attribute
phrase.
Terrified
people
means
people
who
were
terrified.
Now
please
find
two
more
examples
from
the
reading
passages
with
past
participles
used
as
the
attribute.
You
are
allowed
to
find
as
many
sentences
as
possible
in
two
minutes.
(Two
minutes
later,
ask
the
students
to
report
what
they
have
found.)
S1:
From
the
stomach
the
disease
attacked
the
body
quickly
and
soon
the
affected
person
was
dead.
S2:
Immediately
John
Snow
told
the
astonished
people
in
Broad
Street
to
remove
the
handle
from
the
water
pump
so
it
could
not
be
used.
S3:
John
Snow
suggested
that
the
source
of
all
water
supplies
be
examined
and
new
methods
of
dealing
with
polluted
water
be
found.
S4:
He
placed
a
fixed
sun
at
the
centre
of
the
solar
system.
T:
Good.
You
just
found
all
the
sentences
containing
the
past
participles
used
as
the
attributes.
Besides
using
as
the
attribute,
the
past
participles
can
also
be
used
as
the
predicative.
Can
you
find
the
sentences
with
past
participles
used
as
the
predicative?
Finish
it
in
two
minutes.
(Two
minutes
later,
let
the
students
read
these
sentences
with
past
participles
as
the
predicative.)
S1:
Neither
its
cause,
nor
its
cure
was
understood.
S2:
He
knew
it
would
never
be
controlled
until
its
cause
was
found.
S3:
He
got
interested
in
two
theories
explaining
how
cholera
killed
people.
S4:
They
were
given
free
beer
and
so
had
not
drunk
the
water
from
the
Broad
Street
pump.
S5:
He
found
that
it
came
from
the
river,
which
had
been
polluted
by
the
dirty
water
from
London.
S6:
Immediately
John
Snow
told
the

pump
so
it

not

S:
We
use
past

when
we
want
to

Now
let’s
look

过去分词作定语,
在语态上,
表被动;
在时间上,
表示动作已经发生或完成,
与它所修饰的名词有逻辑上的动宾关系。过去分词作定语时,
所修饰的名词在逻辑上相当于被动句中的主语,
过去分词相当于谓语。如:
The
destroyed
house
will
be
rebuilt
next
year.
这种情况下的过去分词为及物动词的过去分词。
不及物动词的过去分词很少能单独作前置定语,
少数表示状态改变或位置转移的动词的过去分词可前置,
仅表示时间的完成,
无被动意义。而现在分词表示动作正在进行。如:
falling
leaves正在下落的树叶　a
developing
country发展中国家　the
boiling
water沸水
fallen
leaves落叶　a
developed
country发达国家　the
boiled
water(凉）开水
T:
Besides
this,
the
past
participle
can
be
put
after
the
noun
to
modify
the
noun
form,
for
example,
The
famous
writer’s
play,
mentioned
in
one
of
my
books,
was
published
in
1963.
Do
you
understand
the
sentence?
S:
The
famous
writer’s
play,
which
was
mentioned
in
one
of
my
books,
was
published
in
1963.
T:
Yes,
very
good.
In
this
sentence
we
can
get
two
pieces
of
information.
A:
The
famous
writer’s
play
was
published
in
1963.　B:
The
play
was
mentioned
in
one
of
my
books.
Now,
let’s
do
some
exercises
to
combine
two
sentences
together
using
past
participle
as
the
attribute.
1.This
is
one
of
the
questions.　It
was
discussed
at
the
meeting
yesterday.
S:

is
one

reached
me
late.
S:

addressed
to
the

know
how

They
were
surprised
at
the
way
the

was
put.

didn’t

S:
The
audience,

by
his
speech,
all

注意下面过去分词作定语的几种情况:
1.单个的过去分词作定语一般放在被修饰的名词之前。如:
the
terrified
people,
the
polluted
water,
the
astonished
people。
单个分词也可以作后置定语,
用以强调动作。如:
They
decided
to
change
the
material
used.他们决定更换使用的材料。
2.过去分词短语作定语要放在被修饰的名词后面,
作后置定语,
其作用相当于一个定语从句。如:

man
chosen
mayor
of
the
city
received
a
Doctor’s
Degree
of
Engineering.
3.如被修饰的词是
something,
anything,
everything,
nothing
等,
分词放在被修饰词的后面。如:
Do
you
have
anything
unfinished?
4.单个过去分词前加一名词或副词,
常用连字符将它们连接起来构成一个复合形容词,
放
在其修饰的名词前,
作前置定语。分词前加的名词表示分词的动作或行为主体,
所加的副词表示方式、时间、程度、性质等意义。如:
a
newly-born
baby,
a
well-known
doctor。
T:
Now
let’s
come
to
the
past
participle
used
as
the
predicative.
Generally
speaking
the
past
participle
used
as
the
predicative
shows
the
state
the
subject
remains.(过去分词作表语表示主语所处的状态。)
eg:

现在分词和过去分词的区别
现在分词和过去分词主要差别在于:
现在分词表示“主动和进行”,
过去分词表示“被动和完成”(不及物动词的过去分词不表示被动,
只表示完成)。分词可以有自己的状语、宾语或逻辑主语等。
1.单个分词作定语一般放在被修饰之前（有些单个过去分词作宾语时,
也可放在被修饰词之后）,
如:
分词短语作定语一般放在被修饰词之后,
有时可用定语从句代替。单个分词作前置定语表示被修饰词所发出的动作,
即分词动作的逻辑主语是它修饰的词。如:
The
exciting
news
that
Chinese
athletes
won
over
20
gold
medals
in
Sydney
2000
Olympic
Games
inspired
all
of
us.（单个现在分词作前置定语,
表示被修饰词所发出的动作,
即The
news
was
exciting.）
The
building
lying
on
the
west
of
the
sea
cost
some
20
000
000
dollars.（现在分词短语作后置定语,
相当于一个定语从句that
lies）
现在分词表示主动的动作或正在进行的主动动作,
如:
boiling
water,
the
rising
sun,
developing
country;
过去分词表示被动动作或已完成的动作,
如:
boiled
water,
the
risen
sun,
developed
country。
2.分词作后置定语应注意:
(1)
现在分词表示的动作:
①一个正在进行的动作,
如:
Can
you
see
the
ship
disappearing
(that
is
disappearing)
in
the
distance?
②表示将来的动作,
如:
Can
you
tell
me
the
number
of
people
coming
to
the
party
(who
will
come
to
the
party)?
③表示某个经常性的动作或状态,
如;
The
girl
looking
after
(who
looks
after)
Harry’s
children
gets
200
dollars
a
week.
(2)
过去分词表示的动作:
①发生在谓语动词的动作之前,
如:
Is
this
the
book
written
(that
was
written)
by
Henry
James?
②与句中谓语动词是相应的经常性的动作,
如:
He
was
then
a
professor
respected
(that
was
respected)
by
all
the
teachers
and
students
of
the
college.
③being+过去分词结构表示动作正在进行,
如:
The
65-storeyed
building
being
built
(that
is
being
built)
will
be
run
by
a
US
company.
正在建设的那座65层大楼将由一家美国公司经营。
④to
be+过去分词结构表示一个将来动作,
如:
He
was
invited
to
the
conference
to
be
held
(that
will
be
held)
in
Shanghai
in
May
2001.
分词前置
We
can
see
the
rising
sun.我们可以看到东升的旭日。
He
is
a
retired
worker.他是位退休的工人。
分词后置
(i.分词词组;
ii.个别分词如given,
left;
iii.修饰不定代词
something等)
There
was
a
girl
sitting
there.有个女孩坐在那里。
This
is
the
question
given.这是所给的问题。
There
is
nothing
interesting.没有有趣的东西。
过去分词作定语
与其修饰的词是被动关系,
相当于一个被动语态的定语从句。
Most

the
people

主语多为人。如:

interesting.故事有趣。

(2)The
