GRAMMAR

This section contains all the theory related to inventions.

There are three main concepts that we will have to learn here:

Past Simple

We use the Simple Past to to talk about actions done in the past. With the past Simple, we express that an action started and finished at a specific time in the past. Sometimes the time of the action is not specified.

* There are two ways to change the Past Simple verbs:

Regular verbs: 

The verbs are ended in -ed.

Examples 

play-played

stay-stayed

invent-invented 

Irregular verbs: 

The form in the past of these verbs is a bit different than the form in the present.

Examples

see-saw

have-had

be-was/were

 

Here's a list of irregular verbs that you should learn by heart.

Past Simple activities

- an is used before a noun that starts with a vowel
