    MODAL VERBS 
The modal verbs are:
can
could
may
might
will
shall
should
ought to
must/have to


We use modal verbs to show if we believe something is certain, probable or possible (or not). We also use modals to do things like talking about ability, asking permission making requests and offers, and so on.

Should (Modals)

Should is used to give advice and to make recommendations. It is also used to express obligation and expectation.

Recommendation: When you go to London, you should go to the theatre. 

Advice: You should try to focus more on your writing skills. Advice

Obligation: I should be going now. It's getting late.

Expectation: You should have understood the text by now.

Most modal verbs have different forms depending on their function when used in the present, past or future times.

To Offer of Assistance or Polite Suggestion (When you are quite sure of a positive answer)

Shall + subject + base form of the verb
  1. Shall we go for a walk?

To Offer of Assistance or Polite Suggestion (When you are not sure of a positive answer)

Should + subject + base form of the verb
  1. Should I call a doctor?

A Prediction or Expectation that Something Will Happen

should/shouldn’t + base form of the verb
  1. The proposal should be finished on time.
  2. I shouldn’t be late. The train usually arrives on time.

To Give Advice

should / ought to + base form of the verb
  1. You should check that document before you send it out.
  2. You ought to have your car serviced before the winter.

To Give Advice (about something you think wrong or unacceptable)

shouldn’t + base form of the verb

Examples:

Must vs. have to

Both Must and have to express obligation or necessity, but there are some small differences: 


•  Must expresses the speaker's feelings, whereas have to expresses, above all, an impersonal idea:

You must come. You are obliged to come (I require that you come)

You have to come. You are obliged to come. (There's a rule requiring you to come)
Must I wear this tie? Am I obliged to wear this tie? (What do you think?)

Do I have to wear this tie? Am I obliged to wear this tie? (Is there a rule about ties?)


•  Have to mainly expresses general obligations, while must is used for specific obligations:

I have to brush my teeth twice a day.
I must tell you something.


Important: To express obligation, duty or necessity in the future or the past, must and need are not used. They are replaced by have to:

We must (need to) buy another ticket. 

We had to buy another ticket yesterday. 

We'll have to buy another ticket later.


However, in their negative forms, mustn't and don't have to have completely different meanings: 



•  Mustn't expresses prohibition

You mustn't drive. You are prohibited to drive. You are not allowed to drive.


•  Don't have to expresses the absence of obligation or necessity:

You don't have to drive. You are not obliged to drive (but you can if you want to).

  1. You must have a passport to cross the border.

So, during the time I was eating (let's say from 6:30-7:00 p.m.) somebody called my house (let's say they called at 6:49p.m.) One thing happened ( simple past ) during the period of time another thing was happening ( past progressive .)
