问题描述:

1.being very brave,he went into the ...
2.being quite ill ,he could not 以上两句使用非谓语动词,being是充当上面成分啊?
3.hearing the music ,be began to miss...
4.seeing the flame on the top of moutain,they knew that ...这里的是现在分词还是动名词?怎么区别?充当什么成分?

1和2的being...是现在分词短语做原因状语.
3和4的ing是现在分词做伴随状语.
只有做主语和作宾语的ing才是动名词.介词后面跟的也是动名词.
区分的标准就是它有没有起名词作用.
