非限定动词(non-finite verb)是动词的非谓语形式。非限定动词和限定动词不同。限定动词(finite verb)在句中用作谓语，受主语的人称和数的限制。如：
I put my book down and look out of the window. 我放下书，望着窗外。
Hunger and disease are would problems. 饥饿和疾病是世界性问题。
非限定动词在句中不可单独用作谓语，不受主语的人称和数的限制;它在句中可以用作其它句子成分。非限定动词有三种，即不定式、动名词和分词。如：
Scientists hope to find a cure for cancer. 科学家们希望找到一种治疗癌症的方法。(不定式to find用作宾语)
Backpacking is popular among college students. 背行李包旅行在大学生中很流行。(动名词backpacking用作主语)
People walking in poorly lighted areas at night should be extremely careful. 夜间在光线差的地方走路的人应当特别小心。(现在分词walking用作定语)
Badly torn garments should be mended by an experienced seamstress. 破得厉害的衣服应当找有经验的女缝工缝补。(过去分词torn和experienced用作定语)
非限定动词由于不能用作谓语，因而没有语法上的主语，但它往往有逻辑上的主语。如：
How can I get to know her? 我怎么能认识他呢?(不定式to know的逻辑主语是I)
I can’t bear him staying up so late. 我不能忍受他这么晚睡。(动名词staying的逻辑主语是him)
Who is that speaking? 您是哪一位?(现在分词speaking的逻辑主语是that)
They plan further talks with interested parties in this question. 他们就此问题打算与有关各方进一步谈判。(过去分词interested的逻辑主语是parties)
非限定动词短语往往可以转化成各种从句。如：
The foreign guests hope to join the National Day celebration of Beijing. → The foreign guests hope that they can join the National Day celebration of Beijing. 外宾希望参加北京的国庆庆祝会。(不定式短语转化成宾语从句)
The man standing there is our English teacher. → The man who is standing there is our English teacher. 站在那儿的那个人是我们的英语教师。(现在分词短语转化成定语从句）
I regret being unable to help. → I regret that I cannot help. 我感到抱歉，不能帮助你。(动名词短语转化成宾语从句)
希望我能帮助你解疑释惑。

简单来说
一句句子只能有一个谓语动词
那其他的动词怎么办呢？
要么你使用连词 另外一个动词有自己的主语 那么就是两句完整的句子用连词连接
要么不使用连词 这个时候除了谓语动词之外的动词 就叫做非谓语
它是动词 但不是谓语 所以是 非谓语
非谓语的形式主要有几种 doing 用于主动语态 发出动作的主语是主动的
V+ed 用于被动语态 发出动作的主语是被动的
两个动词之间用to隔开的形式
