Simple Past

We use the past simple to describe finished events in the past.

Example: * Yesterday I watched a great movie on TV.

There are regular and irregular verbs, for the way they form their past.

The regular verbs ended in “-ed”, for the past and past participle but changed in their pronunciation /Id/, /t/, and /d/. The two syllable regular verbs with the stress on the last syllable double the final consonant.

Example: clap – clapped stop – stopped

The irregular verbs have their own form for past and past participle, and follow different rules for that.

Present Perfect

The present perfect simple expresses an action that is still going on or that stopped recently, but has an influence on the present. It puts emphasis on the result.

We use the present perfect when we talk about our experiences in the past and do not mention an exact time.

Example: I’ve been to Ecuador.

We may explain a present situation by saying what has happened. We do not mention an exact time.

have/has(Aux.) + past participle

Example: Why are you late? I’ve lost my watch.
