下面有一句順口溜"一隨主。二隨賓，第三人稱不更新"。"一隨主"是指在直接引語變間接引語時，如果從句中的主語是第一人稱或被第一人稱所修飾。從句中的人稱要按照主句中主語的人稱變化如：
She said. "My brother wants to go with me. "→She said her brother wanted to go with her.
"二隨賓"是指直接引語變間接引語時，若從句中的主語及賓語是第二人稱?；虮坏诙四闼揎棥木渲械娜朔Q要跟引號外的主句的賓語一致。如果引號外的主句沒有賓語。也可以用第一人稱，如：
He said to Kate. "How is your sister now?"→He asked Kate how her sister was then。

"You have finished the homework, haven't you?" my mother asked. →My mother asked me whether I had finished the homework.

He said, "Let's go to the film." →He suggested going to the film.或He suggested that they should go to see the film.
引述別人的話有兩種方式：一是使用引號引出人家的原話，這叫做直接引語;一是用自己的話把人家的話轉述出來，這叫做間接引語。例如：
John said, "I'm going to London with my father."
約翰說："我要和父親到倫敦去。"(引號內是直接引語)
John said that he was going to London with his father.
約翰說，他要和他父親去倫敦。(賓語從句是間接引語)
