参考范文：
Help
the
Planet
As
we
all
know,
the
environment
pollution
is
more
and
more
serious
during
these
years.
What
we
can
do
is
to
make
great
efforts
in
protecting
the
environment
.
In
fact,
we
can
do
many
things
to
improve
the
environment,
such
as
planting
trees,
reusing
the
things
that
can
be
recycled.
We
had
better
not
use
plastic
bags
any
more.
No
one
can
stand
the
“white
pollution”.
Write
to
the
local
newspapers
to
remind
everybody
to
take
care
of
it.
The
most
important
thing
is
to
let
everybody

2.
作宾语:
作宾语时如果还带有宾语补足语,
往往把不
定式放在宾语补足语之后,而用it
作形式宾语。

【知识拓展】
不定式作宾语补足语省略to

就必须带上to。
I
often
hear
him
sing
the
song.
He
is
often
heard
to
sing
the
song.
4.
作定语：当作定语的不定式是不及物动词，或者不定式所修饰的名词或代词是不定式动作发生的地点、工具等时,
不定式后面必须有相应的介词。

the
river
dangerous
to
swim
in.
He
is
looking
for
a
room
to
live
in.
当作定语的不定式所修饰的名词或代词是不定式动作的承受者时,
不定式既可以用主动语态,
也可以用被动语态。但含义有所不同。
试比较：
I’m
going
to
the
market.
I
have
something
to

【名师点津】
不定式作表语侧重于目的，强调动作将要发生。不定
式作表语时，系动词翻译为“是”，不然就成了固定短语“be

do…”。
【知识拓展】

动词不定式的否定式只须在to前加
not。

二、不定式的时态和语态
1.
不定式的一般形式所表示的动作通常与谓语的动作(状态)同时(或几乎同时)发生,
或是在它之后发生。
I
saw
him
go
out.(同时）
I
plan
to
attend
the
meeting.(之后）
2.
如果谓语表示的动作发生时,
不定式表示的动作正在进行,
这时要用进行时。
I
am
very
glad
to
be
working
with
you.
They
seem
to
be
talking
about
something
important.
(不定式的动作与谓语动词的动作同时发生）
3.
如果不定式的动作发生在谓语动作之前,
就要用完成时。
I’m
sorry
to
have
kept
you
waiting
so
long.
He
seems
to
have
seen
the
film.
(不定式的动作发生在谓语动作之前）
4.
当不定式的逻辑主语是这个不定式所表示的动作的承受者时,
不定式一般要用被动形式。
He
asked
to
be
sent
to
work
in
the
countryside.
This
book

airport,
only
________(tell)
the
film
star
had
left.
【即学即练】
to
be
cleaned
to
be
told
三、but+不定式的用法
1.
不定式在介词
but,
except后面时,
如果这些介词之前有行为动词do
(非助动词)的各种形式时,
那么这些介词后面的不定式不带to,否则带to。
She
could
do
nothing
but
cry.
I
have
no
choice
but
to
wait.
2.
当句子的谓语动词是can’t,
can’t
help,
can’t
choose
等结构时,
but,
except后的不定式符号to也省略。
can’t
help
doing
=
can’t
help
but
do
sth.
情不自禁做某事，不得不做某事
We
can’t
help
but
admire
his
bravery.
我们情不自禁地赞扬他的勇敢。
