Modals are words like 'should'  'can' 'could' and 'might'.

Phrasal modals are similar but use two or  more words like 'have to' and 'had better'.

You can use modals and phrasal modals to  talk about obligations, things we need to do,  

and to give advice.

Obligation is something  necessary: don't walk on the grass

Advice is a suggestion:  you should take an umbrella

In this lesson we discuss two ways  of talking about an obligation  

and two ways of giving a suggestion.

In Episode 4 of Fortune Blue we have a  couple of examples to look at together.

Can you hear the modal or phrasal modal used?

I wanted to say thank you. To say thanks,  

you should buy flowers. Or chocolates.

In this example, Susie uses the  modal 'should' for a suggestion.

Another way to give suggestions  is to say 'had better'.

For example, Susie could say  'you'd better buy chocolates'.

To me, this sounds stronger  than you should buy chocolates.

Now, for the next example listen  for the phrasal modal in the scene.

I'm serious, you have to take care of  yourself. And now this drunk guy...

In this example, Susie uses the phrasal  modal 'have to' for an obligation.

Another way to say this is 'you  should take care of yourself'.

Remember, you can use 'should' to talk  about obligations and to make suggestions'

For obligations, you can also use 'have to'.

For suggestions don't use  'have to', use 'had better'.

I hope you enjoyed this grammar lesson. See you next time.
