间接引语
直接引语
语法精讲
引用或转述别人说的话时有两种方法:直接引述别人的原话,叫作直接引语(direct speech)。用自己的话转述别人的话,叫作间接引语(indirect speech)。一般来讲,直接引语前后要加引号,间接引语不用引号,而用宾语从句来表达。
John said,“I’m going to London with my father.”
→John said that he was going to London with his father.
1.直接引语如果是陈述句,间接引语应改为由that引导的宾语从句。
He said,“You told me this story.”
→He said that I had told him that story.
2.直接引语如果是附加疑问句、选择疑问句或一般疑问句,间接引语应改为由whether或if引导的宾语从句。
She said,“Is your father an engineer ”
→She asked me whether my father was an engineer.
“You have finished the homework,haven’t you ” my mother asked.
→My mother asked me whether I had finished the homework.
“Do you go to school by bus or by bike ” he asked.
→He asked me if I went to school by bus or by bike.
3.直接引语如果是特殊疑问句,间接引语应改为由疑问代词或疑问副词引导的宾语从句(宾语从句必须用陈述句语序)。
“Where have you been,Li Ming ” the teacher asked.
→The teacher asked Li Ming where he had been.
4.直接引语如果是祈使句,间接引语应改为“tell/ask/order/beg/...sb (not) to do sth”句型。
He said,“Sit down,please.”
→He asked me to sit down.
The teacher said,“Don’t talk in class!”
→The teacher told us not to talk in class!
5.直接引语如果是以“Let’s”开头的祈使句,变为间接引语时,通常用“suggest doing sth(或从句)”。
He said,“Let’s go to the film.”
→He suggested going to the film./He suggested that they should go to the film.
【即学即练】单句写作
①My brother asked me 　　　　　　　　　　(我到什么地方去过).
②My friend wanted to know _______________________________________
(我是否愿意和她一起去度假).
③My parents asked me 　　　　　　　　　　　　　(我要做什么) after graduation.
④Can you give me some advice on 　　　　　　　　　　　　　　　(我如何才能学好英语口语)
where I had been
whether I would like to go on a holiday with her　
what I would do　
how I can learn spoken English well
注意:
在以下几种情况下,在直接引语变为间接引语时,时态一般不变化。
(1)直接引语是客观真理。
“The moon moves around the earth,” the teacher told me.
→The teacher told me that the moon moves around the earth.
(2)直接引语是过去进行时。
Jack said,“John,where were you going when I met you in the street ”
→Jack asked John where he was going when he met him in the street.
(3)直接引语中有具体的过去某年、某月、某日作状语。
Xiao Wang said,“I was born on April 20,1980.”
→Xiao Wang said he was born on April 20,1980.
(4)直接引语如果是一般现在时且表示一种反复出现或习惯性的动作。
He said,“I get up at six every morning.”
→He said he gets up at six every morning.
(5)直接引语中的情态动词没有过去时的形式(例如:ought to,had better,used to)或者已经是过去时的形式(例如:could,should,would,might)。
Peter said,“You had better come today.”
→Peter said I had better go that day.
