AS French - ImparfaitWatch
So - I was reading ( Imparfait/Imperfect) je lisais
I was going to read j'allais lire ( imparfait/ imperfect) of aller to go, followed by infinitive of manger to eat.
It's not the tense that makes it followed by the infinitive but the meaning - to read.
You can have an infinitive after any tense.
J'avais lu = I had read
J'étais allé = I had gone
If you make a more specific post, we can help you more. However, I will say that if a verb is followed by another verb, the second one will only ever be a past participle or an infinitive.
any verb used after one has been previously is an infinitive
e.g j'aime etudier- i love studying etudier is in the infinitive form because it is preceded by aime, any verb used after this is as normal then after that is an infinitive
but a helper verb cant be classed as a first verb so is not followed by an infinitive e.g j'ai decide
the decide (e -accent) is not an infinitive because the avoir (ai) is a helper verb but any verb after this IS
j'ai decide d'avoir - i decided to have
