Modal verbs in songs

Listen to these songs and relate them to the modal verbs we have been working today:

Lyrics: Blue - 'I can'

Now we are going to watch this 'My classroom rules' video.


 Can you express the previous ideas with must / mustn't / have to / dont' have to?

After having listened to these samples, here you have some general rules on modal verbs.

• Los modal verbs van seguidos de infinitivo sin to.

I must be a good boy.

I think you should drive more carefully.

• Las 3ªs personas del singular no llevan -S

She can run really fast.

• Las negativas e interrogativas no se forman con auxiliares (don´t, didn´t…)

She can´t play the violin.

Hay un verbo modal que rompe todas estas reglas: HAVE TO

• Va seguido de un verbo en infinitivo con to: I have to be quiet at my English lessons.
• La 3ª persona cambia:: She has to wear a uniform at work
• Porque las negativas y preguntas se hacen con auxiliar: Do you have to study hard? Yes, I do.
