你是否想跟我说你怎麼扔掉某些东西?do you want to tell me that how do you throw something away?这文法有错误么?.可以这样吧?还可以简化么?

Do you want to tell me (that) how you throw something away?

maybe this version is better:
do you want to tell me how to throw away sth?

that可以去掉,但是用不用实际上都没问题

do you want to tell me how do you throw something away
