I don't know how to do it.do后缺宾语,how 问方式
再问： what不也缺宾语吗
再答： do 的宾语就是what
再问： how 和 do 有什么区别
再答： what should i do ?我该做什么问的是做什么对do 后的宾语进行提问, 用what how should i do it?我该如何做这件事问的是怎么去做,一种方式, do 后面是需要宾语的,所以这个it不能省略

为什么I don't know what to do成立而I don't know how to do不成立正常译法是i don't know what to do ,为什么不能用i don't know how to do I don't know what to do i don't know ()to do.填what还是how I don’t know what to do.I don’t know how to do.（ × ）第二句 how i don"t know what to do (next) 和i don"t know how to do (next I don't know "What to do 和 I don't know "How to do it"?哪个句子是 I don't know what to do.为什么不是I don't know what to be done.请高 I understand,but,I don't know what to do? i don't know how to do next还是what to do next I really don't know -----with it.A .what to do B.how to do 选 i don't know how to do it.为何要加It?而what to do 后则不加it?
