English help

Here are some examples so you use tenses correctly. Notice the previous post has a verb list and therefore, you can look at the verb and tense you want to use.
what I normally do:
Nosotros vamos a conciertos 1 vez al año/ Nunca leo sobre arte/ My mama trabaja en su casa.
We go to concerts one time a year / I never read about arts / My mom works at home

When I want to talk about a particular occasion.
En esa oportunidad yo fui al campo/ Nosotros estábamos cansados ese día/ Comió el pastel y se fue.
I went to the country on that occasion /We were tired that day/ She ate the cake and left.
About things that started in the past and continue to the present...
He estado bien cansada ultimamente/ No he comprado tantos dulces / He querido ir pero no he podido
I have been tired lately/ I have not (haven't) bought many sweets/ I have wanted to go but haven't been able to.

When I am talking about the past and I want to refer to something further in the past.

Ese día me di cuenta que lo había visto más temprano. / Hasta entonces no había tenido tiempo.
That day I realized I had seen him earlier./ I hadn't had time until then.

Conditionals
Si tengo tiempo, te llamare.
If I have time, I will call you.

Si tuvierda tiempo, te llamaría.
If I had time, I would call you.

Si hubiera tenido tiempo, te hubiera llamado
If I had had time, I would have called you.


I hope this helps :)
