動(dòng)詞不定式作狀語一般表示目的、結(jié)果作狀語時(shí)候多,此外還可以表示原因.動(dòng)詞ing作狀語時(shí)間、原因、結(jié)果、條件、讓步、方式和伴隨狀語.1、不定式表示目的：eg:I came here only to tell you something about the meeting .（目的是為了告訴“你”.) ing 做狀語：eg:Being a League member,he is always helping others.我認(rèn)為沒有什么太大區(qū)別與聯(lián)系,但是要注意：不定式放句首時(shí),邏輯主語與句子主語要一致.eg:To learn English well,he needs a dictionary.(主語是he ,to learn 也是 he 去學(xué)） 2、不定式表結(jié)果：eg:He ran to the station only to find the train had left.( 結(jié)果發(fā)現(xiàn),火車已經(jīng)開走了.表示一種出乎意料的結(jié)果） ing 做結(jié)果狀語：eg:He was so angry that he threw theglass ,breaking it into pieces.( 結(jié)果杯子摔成碎片,表示一種必然結(jié)果.） 3、不定式表示原因：eg:I'm happy to play with you.(僅僅是一種目的.) ing表示原因：相當(dāng)于一個(gè)原因狀語從句.eg:Not knowing his address,I can't send this book to him.(這也是一種非謂語動(dòng)詞的形式） 4、其他情況的ing eg:While reading the book,he nodded from time to time.(時(shí)間） He stand there for an hour ,wathing the stars in the sky.(伴隨） (If) Playing all day,you will waste your valuable time.(條件） Though raining heavily,it cleared up very soon.（讓步） 滿意答案zer07級(jí)2012-07-10首先澄清一個(gè)問題,動(dòng)名詞和現(xiàn)在分詞是兩個(gè)不同的概念,你說v-ing我不知道指哪個(gè)；其次動(dòng)名詞是不做狀語的,那么我只能將你說的ing理解為現(xiàn)在分詞,現(xiàn)在分詞做結(jié)果狀語通常將其置于句末,因?yàn)椴环旁诰淠┤菀滓鹫`解,但這并不是說放在句末的都是結(jié)果狀語,舉例：I went home,finding the door locked.再如His wife died three years ago,leaving him with five children.而動(dòng)詞不定式做結(jié)果狀語通常只局限于某些特定結(jié)構(gòu)補(bǔ)充：
因不定式主要做目的狀語,常見的結(jié)構(gòu)是only to do如We hurried to the railway station,only to find that the train had just left.其它經(jīng)常見到的還有點(diǎn)so…as to do,…enough to do,too…to do.其中最復(fù)雜的是最后一個(gè)結(jié)構(gòu).不定式和現(xiàn)在分詞做結(jié)果狀語區(qū)別不大,主要是搞清楚做結(jié)果狀語的那幾個(gè)非常常見的結(jié)構(gòu)就好了.
