请求与命令的直接引语与间接引语的表示方法具体解析：

一、祈使句表示要求或命令（command）

比如领导对下属的要求等时，间接引语常采用tell/ order/ command sb. (not）to do sth.的形式

直接引语：Steve said, “Close the window, John!”  

间接引语：Steve told/ ordered/ commanded John to close the window.

否定示例：

直接引语：Steve said, “Don't close the window, John!”  

间接引语：Steve told/ ordered/ commanded John not to open the door.

二、祈使句或疑问句表示请求（request）

间接引语常采用ask/ request/ beg sb. (not) to do sth.的形式。祈使句中的please在间接引语中必须省去。

直接引语：Steve said, “Please close the window, John!”  

间接引语：Steve asked/ requested/begged John to close the window.

否定示例：

直接引语：Steve said, “Please don’t close the window, John!”  

间接引语：Steve asked/ requested/begged John not to close the window.

直接引语：Steve said, “Could/ Would/ Will/ Can you (please) close the window, John?”  

间接引语：Steve asked/ requested/begged John to close the window.

三、当直接引语以Let's开头的祈使句，变为直接引语时，通常用“suggest + V-ing”或“suggest that...(should) do”的形式。

直接引语：Steve said, “ Let's close the window.”  

间接引语：Steve suggested closing the window. 

或 Steve suggested that they should close the window.
