非谓语=to do ,doing主动（持续进行），done被动（完成）

1.站在树下的Tom看着天空。
主干：Tom looks at the sky.

可以变为非限定性定语从句(状语)：

状语=随便放（只要说得通）
Standing under the tree, Tom looks at the sky.
这句话还可以变为：Tom站在树下,看着天空。(用and连词)
Tom stands under the tree and looks at the sky.
And连接两个句子可以有两个谓语（stands, looks）
And=> , 变成一句话只能有一个谓语
Tom standing under the tree, looks at the sky.

2.Tom站在树下，Marry看着天空。

不加and的就是独立主格。
一个用谓语充当主要，非谓语充当次要。
