Hello students! Today we will be discussing how to properly use modal verbs in English. Modal verbs are used to express various degrees of obligation, permission, and possibility. In this exercise, we will be focusing on the modal verbs "may, must, had to, mustn't, should, and don't have to."

Let's take a look at the sentences and see which modal verb fits in each gap.

1. We pay our phone bill today.
Here, the correct modal verb to use is "must". We use "must" to express obligation. So the sentence should be: "We must pay our phone bill today."

2. You bring your car. We'll take mine.
In this sentence, there is no need for a modal verb. So the correct answer is no modal verb.

3. John be more polite to others.
Here, the correct modal verb to use is "should". We use "should" to give advice or guidance. So the sentence should be: "John should be more polite to others."

4. I ask you for a favour?
Here, the correct modal verb to use is "may". We use "may" to seek permission or ask for a favor. So the sentence should be: "May I ask you for a favour?"

5. You ... be late for your interview.
Here, the correct modal verb to use is "mustn't". We use "mustn't" to express prohibition or to say that something is not allowed. So the sentence should be: "You mustn't be late for your interview."

6. She ... work late yesterday.
Here, the correct modal verb to use is "had to". We use "had to" to talk about past obligations or things that were necessary to do. So the sentence should be: "She had to work late yesterday."

Now, let's match the sentences with their appropriate responses.

1. We must pay our phone bill today. - e) That's too bad!
2. You bring your car. We'll take mine. - f) It's better this way.
3. John should be more polite to others. - c) I keep telling him so.
4. May I ask you for a favour? - b) Sure, what is it?
5. You mustn't be late for your interview. - a) Don't worry, I won't.
6. She had to work late yesterday. - d) Ok, I'll do it later.
