例句:She said, "I will join the environmental protection activity."
间接引语:用自己的话转述他人的意思,无需引号
例句:She said that she would join the environmental protection activity.
二、核心变化规则
1. 人称变化(一随主、二随宾、三不变)
一随主:直接引语中的第一人称,随主句主语变化。
例:He said, "I will finish my homework."
→ He said that he would finish his homework.
Grammar
直接引语 & 间接引语

He said, “I am very happy to help you.”
→ He said (that) he was very happy to help me.
2. 直接引语是一般疑问句、选择疑问句或反意疑问句时,间接引语中用whether (...or...或...or not) 或if引导。
He said, “Are you interested in English ”
→ He asked (me) if/whether I was interested in English.
【注意】如果主句中谓语动词是said,则将其改为asked。
直接引语 & 间接引语
Grammar
3. 直接引语为特殊疑问句时,间接引语仍用原句中的特殊疑问词来引导,其余的变化遵照直接引语和间接引语之间的转换规则来进行。
“What's your name ” he asked me.
→ He asked me what my name was.
“Where is your textbook ” the teacher asked me.
→ The teacher asked me where my textbook was.
【注意】疑问句的直接引语变为间接引语时,要把疑问语序变成陈述语序。
直接引语 & 间接引语
Grammar
四、特殊情况
直接引语为客观真理、谚语时,时态不变。
例:
直接:The teacher said, "Water is essential for all living things."
间接:The teacher said that water is essential for all living things.
直接引语为祈使句时,间接引语用 “ask/tell/order sb. to do sth.” 结构。
例:
直接:The leader said to us, "Don't litter in the park."
间接:The leader told us not to litter in the park.
