1.翻译：你是用我指点给你的那种方式/方法工作吗?
2.
1）主句为：Do you work in the way?
而that I have shown you中,that所引导的是定语从句.
2）其中,that称为定语从句的关系代词（也是该从句的引导词）,且that代替先行词（即被定语从句所修饰的名词/代词等）the way,在定语从句中充当shown的直接宾语,此时that可以省略.
即：(that) I have shown you
= I have shown you (that)
= I have shown you (the way)
shown you the way即短语“show sb sth”.
