UNIT 5: Modals to express Degrees of necessity

first of , i´m very glad and satisfied because i learned and understood how to use correctly the topic about modals to express degrees of necessity ,so , this grammar is very important and it was interesting for me , for instance one of them is ´´must´´ where i can make assumptions taht it´s based on information we have , also when i affirmative conclusions that i´m pretty sure that something is true , and it´s used to express obligation that it usually is in a position of power ,adding something more it expresses an urgent necessity.

example: "must"

• you must go to bed right now, karla! (it usually is in a position of power).
• he must live her . his name´s on the door. (it used to affirmative conclusions).
• you really must talk to your boss about a raise (it used to express an urgent necessity).

* we use have to , have got to ( to express necessity and affirmative conclusions )

example:

• you have to press star to begin recording .
• he has to be home .he just answered the phone .

* we use should and ought to (to give advice and ask for advice )

example:

• you should watch ¨ titanic¨ tonight .
• should i buy a new radio ?

* we use had better ( for urgent advice )

example:

• you ´d better stop watching so much tv or your grades will suffer.

* we use could / might( we use for the present and future ,suggestions and could for negative and questions).

example :

• you could win an award .
• it couldn´t start at 10:00. the news is on then

well, that´s all.
