PAST SIMPLE FORM

In English there are regular and irregular verbs. We have to know if a verb is regular or irregular to know how to form the past.

To make the past simple of REGULAR verbs you only have to add -ed to the verb.
       
               live ----- lived
               walk ----- walked

To make the past simple of IRREGULAR verbs you have to know the form of that verb in the past. Remember it's the second column of the verb. Unfortunately there is no way to know if a verb is regular or irregular, so study them!!!!

               go ----- went
               speak ----- spoke

But we are lucky because in the past the verb has the same form for all the persons, there is no change in the third person singular.

                                   I           worked          went  
                                   you       worked         went
                                   he         worked          went
                                   she       worked           went
                                   it          worked          went
                                   we        worked          went
                                   you       worked          went
                                   they      worked          went

POSITIVE

The structure of a sentence is the same as in the present, we only have to use the verb in the past.

               Present: I work as a musician
               Past: I worked as a musician
               
               Present: They go to the cinema every weekend
               Past: They went to the cinema every weekend
               
               Present: She lives in Galway
               Past: She lived in Galway
        
               Present: He speaks very fast
               Past: He spoke very fast

To form the -ed of the regular verbs in the past there are some rules:

1. If the verb ends in -e we only have to add -d
               live ----- lived
               hate ----- hated
               love ----- loved

2. If the final syllable of the verb is stressed and it is a consonant, then we have to double the consonant
               stop ----- stopped
               admit ----- admitted
               prefer ----- preferred

3. If the verb ends in -l then we also duouble the -l
               travel ----- travelled

4. If the verb ends in -y and the -y is preceded by a consonant, the -y turns into -i and we add -ed
               try ----- tried
               study ----- studied

    But if before the -y there is a vowel we just add -ed
               play ----- played
               enjoy ----- enjoyed


NEGATIVE AND INTERROGATIVE

The structure of the negative and interogative sentences is the same as in the present, we know it is past because instead of the auxiliaries do and does, we use auxiliary DID. And, again, it is the same which person it is, 1st, 2nd, or 3rd, singular or plural, the auxiliary is always did.
In positive sentences we have to know if the verb is regular or irregular to know its past form. In negative and interrogative sentences it is not necessary because we use the infinitive of the verb, in the same way we use it in the present simple.

Examples of negative sentences:

               Present: They don't like going to the cinema
               Past: They didn't like going to the cinema

               Present: She doesn't drink a lot of water
               Past: She didn't drink a lot of water yesterday.

Example of interrogative sentences

               Present: Do they like going to the cinema?               
               Past: Did they like going to the cinema?

               Present: Does she drink a lot of water?
               Past: Did she drink a lot of water yesterday?
