1．人称的变化
[语法点津]
直接引语变为间接引语时，人称代词要根据转述人立场的变化作相应的改变。
[巧记] 直接引语变间接引语人称变化口诀：“一随主，二随宾，第三人称不变更。”
(1)“一随主”。指在直接引语变间接引语时，如果从句中的主语是第一人称或被第一人称所修饰，从句中的人称要按照主句中主语的人称而变化。
(2)“二随宾”。指直接引语变间接引语时，若从句中的主语及宾语是第二人称或被第二人称所修饰，从句中的人称要跟引号外的主句的宾语一致。如果引号外的主句没有宾语，也可以用第一人称。
(3)“第三人称不变更”。指直接引语变间接引语时，如果从句中的主语及宾语是第三人称或被第三人称所修饰，从句中的人称一般不需要变化。
