动名词与现在分词用法的区别动词的-ing形式按功能可分为动名词和现在分词。动词的-ing形式何时为动名词，何时为现在分词。首先，我们要从概念上区分。动词的-ing形式在起名词作用时，称为动名词；用作形容词或副词时，称为现在分词。其次，我们要从用法方面区分动词的-ing形式是动名词还是现在分词。一、动词的-ing形式用作主语时为动名词，现在分词不可以用作主语。1动名词用作主语.Reading French is easier than speaking it. 阅读法文比讲法语容易。Talking to him is talking to a wall. 和他说话等于对牛弹琴。Smoking can cause cancer. 吸烟会致癌。Growing roses is her hobby. 种玫瑰是她的爱好。2有时it作形式主语，把动名词主语放在句子后面Its nice seeing you again. 再次见到你太好了。It was tiring driving from morning till night. 从早到晚开车很累人。
