Remember that in reported speech we usually change the tense of the direct statement. The present simple tense changes to the past simple, the past simple changes to the past perfect and so on.
还记得使用间接引语的时候,我们经常要靠改变直接语气的时态来完成。例如一般现在时态变成一般过去时,一般过去时变成过去完成时等等。
Here are some other points to consider.

Can and will
Can与Will

Direct speech: “I can’t remember his name.” Reported speech: She said she couldn’t remember his name.

‘Can’ and ‘can’t’ in direct speech change to ‘could’ and ‘couldn’t’ in reported speech.
直接语气的Can和can’t在换为间接引语的时候,要变成could和couldn’t。
Direct speech: “I’ll be there for 3 weeks.” Reported speech: He told me he’d be there for 3 weeks.
‘Will’ and ‘won’t’ in direct speech change to ‘would’ and ‘wouldn’t’ in reported speech.

Other modal verbs
其他情态动词

Direct speech: “You could be right.” Reported speech: I said that he could be right.
