Present perfect with since and forUnit 1 · Lesson 3
| Question | How long have you had that costume? | How long has he been a comedian? |
| since + a point in time | I’ve had that costume since April. | He’s lived here since he was eight. |
| for + a length of time | I’ve been a comedian for a long time. | They’ve lived here for ten years. |
Watch out: Use since with the time when something started (since 1993, since Monday, since I was eight). Use for with how long it has continued (for two days, for a week, for a long time).
What it means
We use the present perfect to build a bridge between the past and now. With since and for, it tells us that something started in the past and is still true today.
Think of a timeline: the action begins at a point in the past (← 2015) and the line continues all the way to now (→ today). It has not finished. /
The formula
Positive: subject + have
has + past participle + since
for + time
Negative: subject + haven’t
hasn’t + past participle + since
for + time
Question: How long + have
has + subject + past participle … ?
I, you, we, they → have (’ve) · he, she, it → has (’s) /
Examples
I have lived in Muscat since 2015.
My brother has played football for six years.
We haven’t seen our cousins since the summer holiday.
My father has worked at the hospital for a long time.
How long have you known your best friend?, I’ve known her for three years. /
Since or for?: step by step
Ask yourself: Can I point to the moment it started on a calendar or clock? → use since. Am I measuring how long? → use for.
since + a point in time: since 8 o’clock, since Monday, since March, since 2020, since last year, since I was a child
for + a length of time: for ten minutes, for two days, for a week, for six months, for ages, for a long time
Change the sentence: I started learning English in 2020. → I have learnt English since 2020. → I have learnt English for six years. /

Present continuous for future arrangementsUnit 1 · Lesson 5

| Negative | They aren’t flying to Cairo this evening. | He isn’t seeing friends on Saturday. |
| Question | Are you seeing friends tonight? | What are you doing next week? |
Watch out: Use the present continuous for arrangements that are already fixed, a time and a place have been decided. A future time expression is usually added: tonight, tomorrow, next week, on Saturday.
What it means
We use the present continuous to talk about future plans that are already arranged. Something has been organised: we have agreed with another person, bought a ticket, booked a table or fixed a time and place.
Test: Could you write it in your diary or calendar? If yes, the present continuous is usually the best choice. /
The formula
Positive: subject + am
is
are + verb-ing + future time

isn’t
aren’t + verb-ing + future time

Modals of deduction: may, might, could, can’t, mustUnit 2 · Lesson 3
| Almost certain, yes | It must be scared. | It must have scales. |
| Possible | It may be a bird. It might be a bird. | It could have fur. |
| Almost certain, no | It can’t be a hedgehog. | You can’t be right. |
Watch out: After may, might, could, can’t and must, use the base form of the verb with no to: It must be a fish. (NOT It must to be / It musts be.)
What it means
We use modals of deduction to make a guess when we are not completely sure. Like a detective, we look at the evidence, what we can see, hear or know, and decide how certain we are. /
How sure are you?
must → about 95% sure it IS true
may
might
could → about 50%, it is possible
can’t → about 95% sure it is NOT true
Formula: subject + modal + base verb (no to, no -s) /
Examples
Look at those big footprints in the sand! It must be a camel.
Ali isn’t answering his phone. He might be asleep.
That bag could be Salim’s, it’s the same colour as his.
She can’t be at home. I saw her at the beach a minute ago.
Everyone passed the test. Our teacher must be very happy. /
Think like a detective: step by step
1. Find the clue: The animal has feathers and a beak.
2. Decide how sure you are: very sure → must · not sure → might · sure it’s not → can’t
3. Make the sentence: It must be a bird. It can’t be a fish.
Remember: the opposite of must is can’t, not mustn’t. /
Common mistakes
✗ It might to be a bird. ✓ It might be a bird.
✗ He coulds be tired. ✓ He could be tired.
✗ It must is a fish. ✓ It must be a fish.
✗ It mustn’t be a cat. ✓ It can’t be a cat. /

First conditional: If ..., ... will ...Unit 2 · Lesson 5
| if + present simple | If you come with us, | you’ll be with the best animals. |
| Negative in the if-clause | If I don’t join the fish, | they’ll be angry. |
| Negative in the result | If I join the lions, | the birds won’t be happy. |
Watch out: Use the present simple after if, never will. The result uses will / won’t. If the if-clause comes first, put a comma after it.
What it means
We use the first conditional to talk about a real or possible situation in the future and its result. If the first thing happens, the second thing will happen.
Every sentence has two halves: the condition (the if-clause) and the result (the main clause). /
The formula
If + present simple, will
won’t + base verb
will
won’t + base verb if + present simple (no comma)
Question: What will you do if …?
Only the result uses will. The if-clause never uses will. /
Examples
If it rains tomorrow, we’ll stay at home.
If you study hard, you’ll pass the exam.
If we don’t hurry, we’ll miss the bus.
You won’t feel tired if you go to bed early.
What will you do if your team wins the match? /
Build it: step by step
1. Write the condition in the present simple: If I see Maryam
2. Add a comma.
3. Write the result with will
won’t: I’ll give her your book.
4. Check: present simple after if? will in the result? comma after the if-clause? /
Common mistakes
✗ If it will rain, we’ll stay at home. ✓ If it rains, we’ll stay at home.
✗ If I see him, I tell him. ✓ If I see him, I’ll tell him.
✗ If you don’t hurry you’ll be late. ✓ If you don’t hurry, you’ll be late.

going to and willUnit 3 · Lesson 3

| will, a decision made now, or a prediction | I’ll take a small bag, too. | She won’t look for it now. |
| Question | What are you going to do in Salalah? | Will you send me a photo? |
Watch out: Use going to when the plan already existed. Use will for something you decide while you are speaking, for an offer, or for a prediction.
What it means
Both going to and will talk about the future, but in different situations. The key question is: When did you decide?
Decided before you speak → going to. Deciding now, offering, promising or predicting → will. /
The formula
going to: subject + am
is
are + going to + base verb
will: subject + will (’ll)
won’t + base verb
Questions: Are you going to …? · Will you …? /
Examples

Choose: step by step
1. Was the plan made before this moment? Yes → going to
