直接引语和间接引语
引述某人的话可采用两种形式：一种是直接引语，即原封不动地引用原话，将其放在引号内；另一种是间接引语，即用自己的话加以转述，被转述的内容不放在引号内。
陈述句→由that引导的宾语从句，引述动词通常用ask, tell等；
如果直接引语讲的是客观事实或真理，变为间接引语时，时态不变。
eg The teacher said to us, “Light travels
faster than sound.”
→The teacher told us that light travels
faster than sound.
一般疑问句→由连词whether或if引导的宾语从句，其主句谓语动词常用ask, wonder, want to know等。
eg Mother asked me, “Have you finished
your homework ”
→Mother asked me whether/if I had
finished my homework.
选择疑问句→由whether ... or引导的宾语从句。
eg “Are you going to Beijing or Shanghai
for the holidays ” she asked.
→She asked me whether I was going
to Beijing or Shanghai for the holidays.
反意疑问句→由连词whether或if引导的宾语从句。
eg “You don’t like rock music, do you ” he
said.
→He asked me whether/if I liked rock
music.
特殊疑问句→由连接代词或连接副词引导的宾语从句。
eg “How many sleeping pills have you
taken ” asked the nurse.
→The nurse asked me how many
sleeping pills I had taken.
表示请求、劝告、建议等意义的疑问句变为间接引语：suggest + doing或ask/advise +宾语+动词不定式。
eg “What about starting early tomorrow
morning ” Jack said.
→Jack suggested starting early
tomorrow morning.
“Why don’t you take the rest of the day off ” asked my assistant.
→My assistant advised me to take the rest of the day off.
祈使句→动词+宾语+不定式。常见引述动词有tell, order, ask, warn。如果祈使句为否定式，则在不定式前加not。
eg He said to Ann, “Tell me your problem.”
→He told Ann to tell him her problem.
“Be careful with the dog, boys,” she said.
→She warned the boys to be careful with the dog.
“Don’t work in bed, Tom,” she said.
→She told Tom not to work in bed.
【注意】
1. 时态变化

直接引语 间接引语
一般现在时 一般过去时
一般将来时 过去将来时
现在进行时 过去进行时
现在完成时 过去完成时
一般过去时 过去完成时
2. 人称变化

二随宾：直接引语中第二人称变为和间接宾语（即听话人）相一致的人称。
第三人称不更新：直接引语中第三人称变为间接宾语时，人称不变。
3. 指示代词、时间状语、地点状语和动词的变化。
直接引语变为间接引语时，指示代词、时间状语、地点状语和某些动词通常要相应变化。
this -- that ；these -- those；now -- then ；tonight -- that night ；tomorrow -- the next / following day；yesterday -- the day before；here -- there；come -- go。

4. 语序变化
