Unit 26

Something **is going to happen** = we can see now that it is sure to happen. 
	For example: Look at the sky! It’s going to rain.

Unit 28

We often say **I think I’ll …/ I don’t think I’ll…** when we decide to do something.

Don’t use **I’ll…** for something you decided before(use **I’m doing/going** instead)

**Shall I / Shall We …?**  = Do you think this is a good thing to do?

Unit 31

For the past, we use **had to…** (not must):
	For example: I was very hungry. I **had to eat** something.

Unit 33

You can use **must** or **have to** when you say what you think is necessary, when you give your opinion.
When you are not giving your personal opinion, use **have to** (not **must**).
	For example: Jane won’t be at work this afternoon. She **has to** go to the doctor.

Unit 41

You can say **have you? / is it?/ can’t he?** etc. to show that you are interested or surprised:
	For example: Sue isn’t at work today? Isn’t she? Is she ill?
Use **do/does** for the present simple, and **did** for the past simple

You can use **have you? / is it? / can’t she?** etc. at the end of a sentence.
	For example: It’s a beautiful day, isn’t it?

Unit 46

**what’s it like?** = tell me something about it - it it good or bad, big or small, old or new(etc.)

	For example: Is your English getting better?
	For example: At first I didn't like my job, but I'm starting to enjoy it now.

I'm **always doing** something. = I do it too often or more often than normal.
	For example: I'm always leaving my phone at home.

Unit 9

We use the present perfect continuous in this way, especially with **how long,** **for** and **since…** the activity is still happening or just stopped
	For example: How long have you been learning English?

You can use the present perfect continuous for repeated actions.
	For example: Every morning they meet in the same cafe. They have been going there for years.
