英語必修一語法知識點：直接引語和間接引語
概念：直接引語：直接引述別人的原話。一般前后要加引號。
間接引語：用自己的話轉述別人的話。間接引語在多數(shù)情況下可構成賓語從句且不要加引號。
例： Mr. Black said, “ I’m busy.”
Mr.Black said that he was busy.
陳述句的變化規(guī)則
直接引語如果是陳述句，變?yōu)殚g接引語時，用連詞that(可省略)引導，從句中的人稱、時態(tài)、指示代詞、時間狀語、地點狀語都要發(fā)生相應的變化。
人稱的變化——人稱的變化主要是要理解句子的意思
例：1. He said, “ I like it very much.” → He said that he liked it very much.
2. He said to me, “I’v left my book in yourroom.”
→ He told me that he had left his book in my room.
時態(tài)的變化
直接引語 | 間接引語 |
一般現(xiàn)在時 | 一般過去時 |
現(xiàn)在進行時 | 過去進行時 |
現(xiàn)在完成時 | 過去完成時 |
一般過去時 | 過去完成時 |
一般將來時 | 過去將來時 |
過去完成時 | 過去完成時 |
例：
