## Dialogue

| Sally | Hello, my name's Sally, and I have a room reserved for tonight. |
| Receptionist | Hello, Sally. Welcome to the Victoria Hotel. Can I have your passport please? |
| Sally | Here you are. |
| Receptionist | OK. It'll be €55.00 for the night. Your room number is 405 and it's on the fourth floor near the lift. |
| Sally | Great, thanks. Can someone help me with my bags, please? |

| Roger | Here's your room. Is this OK for you? |
| Sally | Yes, it looks fine. |
| Roger | There are some hotel rules which I must tell you about. Firstly, you mustn't smoke in the room and you mustn't make a lot of noise after 10pm. Also you have to vacate the room before 10am. |
| Herr Schwarz | OK, that's not a problem. Are non-guests allowed in the hotel rooms? |
| Franz | Yes, but they have to leave before 10pm. Enjoy your stay at the Victoria Hotel. Good evening. |

## Grammar Focus - Modals of Obligation

Modals of obligation are used to talk about permission and prohibition.
English for B2 students Grammar • Unit 10
Modal Verbs :
| Modal verb | Explanation |
| must | obligations (often personal obligations) |
| mustn't | prohibited, forbidden |
| have to | obligations (often external obligations) |
| don't have to | not required, optional |
| should | recommended, advised |
| shouldn't | not recommended, not advised |
| In most situations must and have to are interchangeable. We often use must when we refer to personal obligations (I must go now because it's late). We often use have to to talk about external obligations which are not our choice (You have to pay taxes). However you are more likely to see must used on signs and in formal situations. ||
| All of the modal verbs remain the same in the 3rd person (i.e. I must, You must, He/She must) except for have to (3rd person is has to). ||
| All of the modal verbs are followed by a verb in the infinitive (I shouldn't smoke) ||
| The past tense of must is had to. The past tense of have to is also had to. ||
| Have to is never contracted. "I have to go to work" NOT "I've to go to work" ||

## Speaking about Rules

Work with a partner if possible to answer these questions.
* Does your workplace or school have many rules? What mustn't you do?
* Can you think of any rules in your local café or shop? What things must or mustn't you do?
* In some countries like Australia you have to vote in elections. Do you think this is a good idea?

## Exercises
