Before entering the subject on which we are willing to discuss, let us analyze the statements in question:
Me I have worked a lot in the last few days.
Is it over there she had spoken all the truth at the time.
In this way, talking about compound times means, above all, sticking to the highlighted forms, having as subsidy the examples mentioned above. They, in turn, consist of an auxiliary verb (have) and a main verb expressed in the participle (worked) (this referring to the first statement). As for the second, the same occurrence prevails, since we are faced with the auxiliary verb (there was) + the main verb (spoken), also expressed in the participle. Thus, upon such assumptions, it is worth noting that only the auxiliaries (have and have) are inflected.
In this sense, let us make sure about how the linguistic fact in question takes place in practice. Therefore, we support the verb to sing (acting as the main one) and having as an auxiliary the verb to have, which is expressed in the tenses referring to the indicative mode:
Do not stop now... There's more after the advertising ;)
Indicative mode
past tense perfect
I have been singing
you have been singing
has sung
we have sung
you have sung
have sung
We infer that at such time the auxiliary verb is in the present tense.
Past perfect past tense
had sung
you had sung
had sung
we had sung
you had sung
had sung
We found that the auxiliary verb is in the past tense imperfect
future of the present
I will have sung
you will have sung
will have sung
we will have sung
you will have sung
will have sung
We note that the auxiliary verb is in the present tense.
Future of past tense
would have sung
you would have sung
would have sung
we would have sung
you would have sung
would have sung
We realized that the auxiliary verb is in the past tense future
