动词ing作状语时间、原因、结果、条件、让步、方式和伴随状语.1、不定式表示目的：eg:I came here only to tell you something about the meeting .（目的是为了告诉“你”.) ing 做状语：eg:Being a League member,he is always helping others.我认为没有什么太大区别与联系,但是要注意：不定式放句首时,逻辑主语与句子主语要一致.eg:To learn English well,he needs a dictionary.(主语是he ,to learn 也是 he 去学） 2、不定式表结果：eg:He ran to the station only to find the train had left.( 结果发现,火车已经开走了.表示一种出乎意料的结果） ing 做结果状语：eg:He was so angry that he threw theglass ,breaking it into pieces.( 结果杯子摔成碎片,表示一种必然结果.） 3、不定式表示原因：eg:I'm happy to play with you.(仅仅是一种目的.) ing表示原因：相当于一个原因状语从句.eg:Not knowing his address,I can't send this book to him.(这也是一种非谓语动词的形式） 4、其他情况的ing eg:While reading the book,he nodded from time to time.(时间） He stand there for an hour ,wathing the stars in the sky.(伴随） (If) Playing all day,you will waste your valuable time.(条件） Though raining heavily,it cleared up very soon.（让步） 满意答案zer07级2012-07-10首先澄清一个问题,动名词和现在分词是两个不同的概念,你说v-ing我不知道指哪个；其次动名词是不做状语的,那么我只能将你说的ing理解为现在分词,现在分词做结果状语通常将其置于句末,因为不放在句末容易引起误解,但这并不是说放在句末的都是结果状语,举例：I went home,finding the door locked.再如His wife died three years ago,leaving him with five children.而动词不定式做结果状语通常只局限于某些特定结构补充：
因不定式主要做目的状语,常见的结构是only to do如We hurried to the railway station,only to find that the train had just left.其它经常见到的还有点so…as to do,…enough to do,too…to do.其中最复杂的是最后一个结构.不定式和现在分词做结果状语区别不大,主要是搞清楚做结果状语的那几个非常常见的结构就好了.
