同学你好~
He 主语
made 谓语
a will 是宾语
leaving all his money to his daughter是动名词短语作同位语，说明will的具体内容，也就是把所有的钱都给他的女儿。
其中all his money是leaving的宾语
to his daughter是宾语补足语

动名词短语作同位语，一般是对前面名词的内容进行解释说明，这种用法很少，但确实存在，比如
His habit listening to music has been made since 2000. 这里listening to music说明具体是什么习惯。
He is looking for a job, repairing cars.
repairing cars 应看作同位语，进一步解释说明job的内容，意思是：The job is repairing cars.

也可以在这里看看同位语的用法
