★动词不定式是一种非谓语动词形式，
1：结构为“to＋动词原形”，即to
do
结构
其中to不是介词，而是动词不定式的符号，动词不定式没有人称和数的变化。本单元主要学习其作宾语，状语，宾补的用法。
2：否定形式：
（1）动词不定式的否定式是直接在to之前加not.
例：Tell
them
not
to
play
football
in
the
street.
?（2）省to的动词不定式，它的否定形式直接在动词前面加not.
例：
Let
the
boy
not
go.
???
??一.不定式作宾语
主语+谓语动词+to
do
动词不定式（短语）可以放在一些动词后面用作宾语，这类动词有：begin,
want,
remember,
agree,
learn,
like,
decide,
fail等。例：
Mario
wants
to
be
an
animal
doctor.
I
hope
to
work
outside.
???
二.
不定式作宾语补足语:
主语+谓语动词+
sb
+
to
do
动词不定式作宾语补足语，表示宾语所做的动作
这类动词有：tell,
ask,
want,
like,
invite,
help等。例：
My
parents
always
ask
me
to
study
hard.
It
can
help
him
to
get
his
future
dream
job.
?
在一感feel,二听hear,
listen
to,
三让have,
let,
make,
四看见see,
watch
,notice,
look
at,半帮助help等动词后面,
一般要省略动词不定式符号“to”，例：

now.
I
often
hear
the
girl
sing
in
the
next
room.
???
I
often
help
my
mother
（to）do
housework.
口诀：
一感二听三让四看半帮助
三.
不定式作状语：
主语+谓语+（宾语）+（状语）+to
do
例：
The
bus
stopped
to
pick
up
