Pay

上面例子中主要行为动词后面的动词
都采用了“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，在句子中不能单独作谓
语，其否定形式是“not
to
+
动词原形”。
什么是动词不定式(‘to-infinitives’)？

1)动词不定式作宾语
后面能接不定式作宾语的动词有很多，如agree,
ask,
choose,
decide,
forget,
remember,
hope,
learn,
want,
wish,
would
like,
prepare,
fail,
start,
begin,
plan,
try,
seem,
promise，refuse等。

before
dark.

The

do
it
herself.
那个姑娘决定自己做那件事。
______
____
2)
有些动词跟不定式与
跟动名词作宾语含义不同：
记住要做某事
remember
to
do
sth
；
记得曾经做过某事remember
doing
sth
忘记要做某事
forget
to
do
sth
忘记曾经做过某事forget
doing

停下来去做某事
stop
to
do
sth
停止做某事
stop
doing

继续做另一件事

3.动词不定式的否定形式
动词不定式的否定式是在to前加not；不带to的不定式则在动词前加not。如：
张明要我不要整天呆在家里。Zhang
Ming
asked
me
not
to
stay
at
home
all
day.
妈妈让我不要独自做这件事。
My
mother
let

1.
当我们猜测某件事发生的可能性时，常
用may来表示“也许”、“可能”。
2.
当句子中已经有谓语动词，而我们又要
表达不止一个动作概念时，其余的动词
可以使用非谓语形式表达。动词不定式
就是动词的一种非谓语形式，其肯定形
式是“to
+
动词原形”，其否定形式是
“not
to
+
动词原形”。无人称、数和时态
的变化。
