We decided to advertise our new product.这句中的主语是“we"谓语是”decided"那to advertise是什么成分
可为什么有一种说法说to do 是非谓语动词在句中不能单独充当谓语（但可以和情态动词或助动词一起充当谓语）上面这句中的to do可以理解为宾语也可以理解为与decide共同构成的谓语到底哪种说法才是正确的啊?

to advertise是动词不定式作宾语.
上面这句中的to do可以理解为宾语,但不可以理解为与decide共同构成的谓语.
“非谓语动词在句中不能单独充当谓语,但可以和情态动词或助动词一起充当谓语”,这只是非谓语动词用法中的一小部分.如：
I'm going.现在分词（非谓语动词中的一种）going与助动词am一起构成谓语.
She has done it already.过去分词（非谓语动词中的一种）done与助动词has一起构成谓语.
The job is done.done与助动词is一起构成谓语.
在更多情况下,非谓语动词与谓语毫不相干,而是充当主语、宾语、状语等其他成分.如：
Seeing is believing.(seeing主语,believing表语）
I suggest/advise going to the farm.(going宾语）
I advise you to go to the farm.（to go宾语补足语）
I've come to help you.（to help 目的状语）
（不过,这句话中的come也是非谓语动词,它与助动词have一起构成谓语）
