直接引语如果是陈述句，变为间接引语时，用连词that（可省略）引导，从句中的人称、时态、指示代词、时间状语、地点状语都要发生相应的变化。

人称的变化——人称的变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.

1. He said to me, “I’v left my book in your room.”

→ He told me that he had left his book in my room.

时态的变化

例：

“I don’t want to set down a series of facts in a diary,” said Anne.

→Anne said that she didn’t want to set down a series of facts in a diary.

The boy said, “I’m using a knife.”

→ The boy said that he was using a knife.

▲注意：如果直接引语是客观真理，变为间接引语时，时态不变，如：

He said, “Light travels much faster than sound.”

He said that light travels much faster than sound.

指示代词、时间状语、地点状语和动词的变化
