Following rules are applied to change tenses in direct and indirect.
In above mentioned examples reporting speeches are in present indefinite and future indefinite respectively so we cannot change tense of reported speeches in both sentences. Tense of reported speeches in both sentences remains present indefinite.
In above stated examples we change present indefinite of reported speech into past indefinite and present continuous into past continuous because there is past tense in reported speech. How actually this change takes place, in sentence no.1 present tense changes into past i.e indefinite will remain indefinite only present changes into past so it becomes past indefinite. In second sentence continuous will remain continuous only present changes into past and it becomes past continuous. Table given below will further clarify your concept.
Present Indefinite | changes into | Past Indefinite |
Present Continuous | changes into | Past Continuous |
Present Perfect | changes into | Past Perfect |
Present Perfect Continuous | changes into | Past Perfect Continuous |
Is,am,are | changes into | Was,were |
Can | changes into | Could |
May | changes into | Might |
Shall | changes into | Should |
Will | changes into | Would |
Can have | changes into | Could have |
May have | changes into | Might have |
Shall have | changes into | Should have |
Will have | changes into | Would have |

In above stated examples we change past indefinite of reported speech into past perfect and past continuous into past perfect continuous because there is past tense in reporting speech. So present tense canges into past and past changes into past perfect in every reported speech if there is past tense in reporting speech. Table given below will further clarify your concept.
Past Indefinite | changes into | Past Perfect |
Past Continuous | changes into | Past Perfect Continuous |
Was,were | changes into | Had been |
Did not eat | changes into | Had not eaten |
Should | changes into | Should |
Would | changes into | Would |
Could | changes into | Could |
Might | changes into | Might |
Must | changes into | Must |
Ought | changes into | Ought |
In above stated examples we do not change past Perfect of reported speech. So we can conclude, present tense canges into past, past changes into past perfect and past perfect does not change in any reported speech if there is past tense in reporting speech. Table given below will further clarify your concept.
Had eaten | changes into | Had eaten |
Had been | changes into | Had been |
Should have | changes into | Should have |
Would have | changes into | Would have |
Might have | changes into | Might have |
Could have | changes into | Could have |
In above stated examples we can not change tense of reported speech because reported speech is universal truth and universal truth always remains in present tense.
