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过去进行时过去进行时（不变）一般过去时过去完成时“Idon’tknowthat,”hesaid.Hesaidthathedidn’tknowthat.注意：直接引语变成间接引语时，以下情况，时态不变：1.主句的谓语动词是现在时，从句时态不变;2.直接引语描述:客观事实、真理名言、习惯性动作,从句时态不变;3.如果直接引语中由具体的过去某年/月/日作状语，从句时态不变。

4.直接引语如果是一般现在时。表示一种反复出现或习惯性的动作，变间接引语，时态不变。5.如果直接引语中的情态动词没有过去时的形式,时态不再变（例：could,

should,

would,

might） 或已经是过去时的形式时，时态不再变。（例：oughtto;hadbetterusedto）ObserveandDiscover：
