非谓语动词是英语中一个重要的组成部分，掌握了她我们就能了解很多词组和词的用法，这几年高考中选择题出题频率较高，因此掌握它确实属于一个重难点，由于非谓语动词包括较多，给我们记忆带来麻烦，怎么才能有效的记忆呢，下面是保定一对一辅导专家给我们带来的锦囊妙计。
非谓语动词主要包括不定式&动名词&分词(现在分词和过去分词)，.即动词的非谓语形式除了不能独立作谓语外,可以承担句子的任何成分
它有三种形式：不定式，分词(现在分词、过去分词)，动名词
1.非谓语动词与谓语动词的相同点有：
(1)如果是及物动词都可与宾语连用，例如：
They built a garden.
They suggested building a garden.
(2)都可以被状语修饰：
The suit fits him very well.
The suit used to fit him very well.
(3)都有主动与被动, “体”式(一般式;进行式;完成式)的变化。例如：
He was punished by his parents.(谓语动词被动语态)
He avoided being punished by his parents.(动名词的被动式)
We have written the composition.(谓语动词的完成时)
Having written the composition, we handed it in.(现在分词的完成式)
(4)都可以有逻辑主语
They started the work at once.(谓语动词的逻辑主语)
The boss ordered them to start the work.(动词不定式的逻辑主语)
We are League members.(谓语动词的主语)
We being League member, the work was well done.
(现在分词的逻辑主语)
2、非谓语动词与谓语动词的不同点有：
(1)非谓语动词可以有名词作用(如动词不定式和动名词)，在句中做主语、宾语、表语。
(2)非谓语动词可以有形容词作用(如动词不定式和分词)，在句中做定语、表语或宾语补足语。
(3)非谓语动词可以有副词作用(如动词不定式和分词)，在句中作状语。
(4)谓语动词在句中作谓语，受主语的人称和数的限制;非谓语动词在句中不能单独作谓语，它不受主语的人称和数的限制。
(5)英语中不能单独做句子的谓语。
[编辑本段]功能及用法
(一)动词不定式：(to)+do，具有名词、形容词、副词的特征.
否定式：not + (to) do
(1)一般式：不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后.
例如：
I'm glad to meet you.
He seems to know a lot.
We plan to pay a visit.
He wants to be an artist.
The patient asked to be operated on at once.
The teacher ordered the work to be done.
(2)进行式：不定式的进行式所表示的动作与谓语动词动作同时发生，例如：
The boy pretended to be working hard.
He seems to be reading in his room.
(3)完成式：不定式的完成式表示的动作发生在谓语动词动作之前，例如：
I regretted to have told a lie.
I happened to have seen the film.
He is pleased to have met his friend.
2.不定式的句法功能：
(1)作主语：
To finish the work in ten minutes is very hard.
To lose your heart means failure.
动词不定式短语作主语时，常用it作形式主语，真正的主语不定式置于句后，例如上面两句可用如下形式：
It is very hard to finish the work in ten minutes.
通过老师的详细解答，相信大家对非谓语动词有了一个简单的看法，上面所讲的只是抛砖引玉而已，其实还有好多值得我们去学习去记忆，大家在以后的学习中要勤奋点，争取掌握它的用法，考试时就迎刃而解了。
