Unit 8 - Modal Verbs

Katie: I have to prepare to teach my classes tomorrow.
Pat: What must you do?
Katie: I have to create some activities for my students and make copies.
Pat: Must you do that tonight? Can you wait until morning?
Katie: No, I have to do it tonight. I must finish before 9:00 pm because my favorite show will be on TV.
Pat: I hope you don't have to do too much!

Modals (Must/Have To)

Must and have to are modal verbs often used to convey necessity.
- I have to go home now.
- I must arrive by 12.00.

Have to is used for general necessity. For example:
- I have to finish this before 12.00. (I have a general obligation to finish this by 12.00)
Must is used for necessity which we feel personally.
- I must finish this before 12.00. (I have a sense of strong personal responsibility to finish this.)

Must does not have a past form, we have to use have to for the past.
- I had to get up early this morning.
- I must got up early this morning. This is incorrect.

Note that have to inflects like a normal verb, it can have different tenses and uses auxiliary verbs for questions and negatives. For example:
- Do we have to go out tonight?
- You don't have to come with us.

Must doesn't use auxiliary verbs or different tenses.
- Must we go out tonight? (This sounds rather British, I really don't want to go out tonight.)
- We mustn't forget the tickets. (No auxiliary verb "to do", just add not.)

Negative Forms

Don't have to means that something is not necessary, but possible.
- You don't have to come, but you can if you want to.
- We don't have to leave today.

Must not is strong and means that something is prohibited.
- You must not push the red button.
- We mustn't be late.

Must and have to - Certainty

Must and have to can also express certainty.
- This must be the right way.
- This has to be the right way.

Must doesn't use auxiliary verbs or different tenses.

Negatives and questions are less common and even more British.

Would 2

Would is a modal verb expressing some kind of imaginary or hypothetical situation. Here are some more uses of would continuing from the previous unit.

Wish ... Would

Wish...would is used when the speaker wants a present situation to be different. The speaker is dissatisfied with the situation and believes that the thing wished for is unlikely to actually happen. For example:
- I wish Jane would call me.
- I wish they would stop fighting.
- I wish the dog would stop barking.
- I wish the dog wouldn't keep barking.

Because wish...would is often used to complain, it's unusual to use this structure to talk about yourself. For example:
- "I wish I'd study more." This is unusual though not incorrect.

Wish...would is used for actions, but not normally for states.
- I wish I had more time. To "have" something is a state not an action, so we use the past tense "had".
- I wish I would have more time. Incorrect
- I wish I knew the answer.
- I wish I would know the answer. Incorrect

Would rather

Would rather + verb (base form) is used to express a preference. It often implies that we don't like other available choices. For example:
- "Let's go shopping this evening". "Oh, I'd rather go tomorrow." (And I don't want to go this evening)
- "Which book would you rather buy?" "I'd rather buy this one. That one isn't so good."

Would rather is also used with the past simple when giving a strong request, usually with some authority.
- Can I meet John after lunch, Mom?" "Yes, but I'd rather you did your homework first".
- "I'd rather you didn't tell anyone about the party. It's going to be a surprise."

All structures with would rather are more often found in British English.

Would mind

Would mind is used to make a polite request. For example:
- "Would you mind closing the window?"
- "Would you mind waiting a few minutes? I need to buy some stamps."
- "Would you mind if we didn't come tonight? We're just really tired, that's all."
