直接引语变间接引语时一定要用ask?

不一定用什么都可以？答：直接引语变间接引语就是写成宾语从句或动词不定式短语，要注意以下几点：人称变化、时态变化、宾语从句要用陈述句的语序。1、直接引语是陈述句，变成间接引语，由连词that 引导。例如：She said: “ I am very happy to help you.”She said that she was very happy to help you. 2、直接引语是一般、选择或反问疑问句，变成间接引语，由连词whether或if 引导。例如：He asked me: “Do you come from China?”He asked me if/whether I came from China.注意：大多数情况下，if ,whether 可以互换，但句中出现or not,或放在介词后作连接词，只用whether。例如：She asked whether he could do it or not.They cried out whether he was all right.3、直接引语是特殊疑问句，变成间接引语，由相应的疑问词who ,whom, whose, how, when, why, where等引导。例如：My sister asked me : “ What is your friend?”My sister asked me what your friend was.4、直接引语是祈使句，变成间接引语，把动词原形变成动词不定式，并在动词不定前加tell, ask, order 的宾语。例如：The solider ordered:” Be quiet.”The solider ordered us to be quiet.注意：否定句，在动词不定式前加notMy teacher asked me :” Don”t laugh .”My teacher asked me not to laugh.5. 一些注意事项（！）直接引语是客观事实、永恒真理，变成间接引语时，时态不变。例如：They told their son :”The earth goes round the sun.”They told their son that the earth goes round the sun.（2）直接引语变间接引语时， 指示代词、时间、地点状语作相应的变化。例如：thisthat , thesethose, nowthen, todaythat day, yesterday—the day before, last year---the year before,ago—before, here---there （3）直接引语是复合句，以since, when, while 引导的状语从句，变成间接引语时， 只改变主句的时态，不改变从句的时态。例如：He said : “Jim is doing his homework when his father came in.”He said that Jim was doing his homework when his father came in.（4）间接引语一定要用陈述句的语序，即主、谓、宾的顺序。例如： They asked: “ where are you from?”They asked where you were from.
