动词不定式
不受句子主语（人称，单复数）和句子时态限定的动词形式；是一种非限定性动词，但仍保留动词的性质，可以有自己的宾语,状语和逻辑主语
定义
构成
形式
I want Tom to help me tomorrow.
He wants Tom to help me tomorrow.
They wanted Tom to help me tomorrow.
思考：为什么这种动词形式叫做动词不定式呢？
宾语
状语
逻辑主语
由to＋动词原形构成，to是不定式符号
（在感官动词、使役动词和help后做宾补时，通常to省略）
感官动词:see,watch,notice，
look at; hear,listen to; feel
使役动词: let，make，have
help
及物动词（短语）
sb./sth.
宾语
sb./sth.
sb/sth.
do
宾补
do
(to) do
现在式
被动式
not to sleep
to be heard
laugh
这类带有逻辑主语的不定式，称为不定式的复合结构。
Exercise：
动词不定式的作用
It is dangerous to swim in the river.
To see is to believe.
Sb.+动词+it+形容词+to do sth.
To swim in the river is dangerous.
It is+形容词+for sb./sth. to do sth.
It is+形容词+of sb./sth. to do sth.
It's a/one's+n.（task/duty/job）...+to do sth.
My work is to clean the room every day.
I want you to help me.
感官动词see，watch，notice，look at;hear，listen to;feel 使役动词 let，make，have
help sb/sth. (to) do
做后置定语
如果不定式动词与被修饰词之间有逻辑上的动宾关系，并且该动词是不及物动词，则需要加上适当的介词或副词使动宾关系成立；如果不定式动词与被修饰词place，time，way，reason之间有动状关系时， 不定式中的介词常省略 。

to laugh
(3).I have a lot of homework to be done .
to do
need ,require“需要”后常用doing 代替被动to be done
Exercise
I
To exercise
感官动词、使役动词和help:主动to不带，被动to回来
感官动词后宾语时动作承受者时，要用动词过去分词作宾补
当句子中出现了不定式的执行者时，常用主动表示被动
与所修饰的词构成动宾关系时，要保证及物动词的完整性
已经有了逻辑宾语，后面就不能再出现宾语
