请给我讲一讲这句话的语法结构Do this by dividing the children into 3 groups and having them discuss this question有DO THIS+BY+现在分词短语这种结构吗?如果DO引导的祈使句省略了主语,BY引导的现在分词短语是宾语,那THIS是做什么的?

请给我讲一讲这句话的语法结构
Do this by dividing the children into 3 groups and having them discuss this question
有DO THIS+BY+现在分词短语这种结构吗?
如果DO引导的祈使句省略了主语,BY引导的现在分词短语是宾语,那THIS是做什么的?

this是宾语,by引导的短语作方式状语
