我们可以发现动词不定式的另外两种语法功能：
①在“动词+宾语+动词不定式”的结构中充当宾语的补足语
②
在句中表示行为动作的目的，作目的状语
1.
什么是动词不定式？
主要行为动词后面的动词采用了“to+动词原形”的结构，我们把这种结构称为动词不定式（有时可以不带to）。动词不定式没有人称和数的变化，在句子中不能作谓语。下面我们一起来看一下动词不定式有哪些语法功能。
语法探究
2.
动词不定式的语法功能：
(1)
不定式作主语
不定式作主语时，常用it作形式主语，而将作主语的不定式放在句子后部。
eg.
It
is
good
to
help
others.帮助他人是好的。
It
is
exciting
to
surf
the
Internet.
上网是令人兴奋的。
(2)
不定式作宾语
学习不定式作宾语时,要注意掌握后接不定式作宾语的动词。常见动词有:
want,
hope,
wish,
like,
begin,
try,
need,
forget,
agree,
help
等。
Many
people
decide
not
to
think
about
it.
许多人决定不去考虑这件事。
I
want
to
go
to
the
library.
我想去图书馆。
(3)
不定式作定语
不定式修饰名词或代词，起形容词的作用，在句中作定语，放在被修饰对象的后面。请看下列句子：
I
have
a
lot
of
homework
to
do.
我有很多作业要做。
I’m
hungry.
Give
me
something
to
eat,
please.
我饿了。请给我点吃的吧。
(4)
不定式作状语
不定式常作目的状语、原因状语、结果状语等。不定式作状语时，要注意不定式的逻辑主语应与句子的主语保持一致。
I
came
to
Beijing
to
see
my
grandpa.
我来北京看望我的爷爷。
I’m
glad
to
meet
you！很高兴见到你！
I’m
too
tired
to
walk.
我太累了，走不动了。
(5)
不定式作补足语
不定式可以作补足语。例如：
She
told
me
to
buy
a
ticket.
她让我去买张票。
(6)
不定式作表语
不定式还可以作表语。例如：
Our
duty
today
is
to
clean
the
floor.
今天我们的任务是扫地。
