爱华网伴随状语出现的条件是：
1) 由一个主语发出两个动作
2) 或同一个主语处于两种状态，

伴随状语首先是一种状语，用来修饰动词的，同时是表示与谓语动词同时进行，即伴随着谓语动词的动作同时进行。如：
He said it angrily pointing at the notice on the wall.
他生气地说着，手指着墙上的布告。
这里，point与said同时进行，因此，pointing在这里是现在分词作伴随状语，表示主动和正在进行。
例子:
1He died doingwhat made him happiest.
2He laughedlooking at the funny boy.
