实际很简单,只要看该非谓语动词的是否及物就能解决问题:如果该动词及物,而后面又有宾语,那就用ing形式或者to do形式;如果没有宾语,则用ed形式;如果是不及物,则用ing形式或者to do形式;例如:
------(smile, 不及物)at me, she gave me a book. 此处应填Smiling.
-------(scold,责骂,及物)by his father, he was sad. 此处应填Scolded,
------(do,及物)homework quickly, you should be familiar with what you have learned. 此处表目的,用To do
