MODALS PART 2 (2º ESO)

Hello students of 2º ESO!!

Today we're going to see two verbs that are considered semi-modals: NNED TO AND HAVE TO. They are called semi-modals because theyy are used as modals but thet have the particle TO.

NEED TO 

It expresses that something is necessary. It can be used in affirmative, negative and interrogative sentences:

Do you have a minute? I need to talk to you about something.
I don't need to be told that I should lose weight.
Do you need to use the hairdryer?
If you want good results, you will need to work harder.

HAVE TO

Have to expresses external obligations, which come from outside of the speaker. These may be rules and regulations imposed by an external authority:

I have to get to work by 9 every day.
Do you have to wear a uniform at your school?

Absence of obligation is expressed with the negative form of have to, not with mustn't. Mustn't is used to express that it is necessary not to do something:

I don't have to get up early tomorrow. It's a holiday. (I can get up late.)
You mustn't tell anyone. It's a secret. (Don't tell anyone.)

 

*As you can see, to form the negative and interrogative we use don't, doesn't and do. 

If you still have doubts about this, you have an explanation in Spanish on Pages 105 and 106 of your Workbook. Also, you can leave a comment on this post.

Take care!!!!!
