May and Might

May and might are modal verbs that we use to talk about possible actions now or in the future. When using them this way, they mean the same thing.

We don’t use may or might in Yes / No questions. We use will or be going to instead. May and might can appear in the answers to these questions.

We use might in Wh- questions.

For example: What might happen? Who might win the race?

We don’t use the short form (contractions) for the negative of may or might.

For example: I might not go to school tomorrow.

Like all modals (L2U2L3), may and might:

1. are followed by the base form of the verb without to.
   For example:I may clean my room tomorrow.
2. have the same form with all subjects (no –s or –ing).
   For example: She might not like this cake. They might not like it, either.

I	may / might may not / might not	stay	I may stay after school.
You		be	You might be right.
He She It		arrive	He may not arrive today.

They

The expression may as well / might as well means that there is no reason not to do something.

(Be) Supposed to

We use (be) supposed to when we want to show that:

1. we expect something to happen (we think something will happen).
   For example: The movie is supposed to start at 7:00.
2. we expect certain behavior (we think that something must happen in a certain way).
   For example: I am supposed to clean my room today.
3. most or many people think a certain thing.
   For example: It’s supposed to be a good movie.

In the past tense, (be) supposed to (was / were supposed to) means that we expected something to happen, but it didn’t.

For example: They were supposed to meet us at 2:00.

When speaking about the future, we use the present tense of (be) supposed to.

For example: He is supposed to travel to England next week.

In the negative, it can sometimes mean that something isn’t allowed.

For example: You’re not supposed to eat here.
