谁能帮我简单梳理一下非谓语动词的用法··
非谓语动词形式包括动名词、分词与不定式三类.不定式、分词与动名词都保留了动词的特征.分词如形容词,只没有名词的特征.动名词则只有名词的特征.不定式除不能独立做谓语外,可作句中每个成份.分词不能作主语,宾语和同位语.动名词不能作状语和谓语.
1.不定式和动名词都可以作主语,区别在于：不定式一般用于表示比较具体的某次行为或动作,而动名词则表示比较抽象的行为或动作.多数情况下,二者还可以互换,意义上没太大的差别.
eg:To smoke so much is not good for you.(具体）No smoking is permitted here.(抽象）
2.作谓语：现在分词用于构成各种进行时态；过去分词用于构成各种完成时态及被动语态.
eg:I am writing some words. He was reading at that time.
He has finished the work. English is spoken widely.
3.作宾语：不定式与动名词的比较.它们的搭配范围不同.
