Hello my.
Lovely students.
Do you ever get confused between:
Can, could, should, will, shall, might, must.
Well, today you're going to learn how to use modal verbs and at the end I'm going to QUIZ you.
Welcome back to JForrest English, of course.
I'm Jennifer.
Now let's get started.
First, let's talk.
About modal.
Verbs of ability.
Can you know this one already?
She can speak four languages fluently.
Or I.
Can see the.
Stars tonight Notice for the.
Structure we.
Have our subject, then we have the modal verb and what comes next.
The base verb.
I can.
See the base verb.
I can see the.
Stars tonight you can't say ah can't you can't say I can to.
See.
The stars tonight.
Using the infinitive is grammatically incorrect.
So remember.
That structure.
Subject, modal, base, verb.
Don't worry about taking notes because I.
Summarize everything in a.
Free lesson PDF.
You can find the link in the description you can.
Use could.
For.
Past ability.
When I was younger, I could run fast.
Now because you use could which is past ability, this means that today.
I can't run fast or I can't run.
As fast as I could.
In the past, notice I used the negative and contraction.
Today I can't run as fast.
So the structure here is subject modal not.
Often formed as a contraction, so pay.
Attention to.
Those contractions and then the.
Base verb.
I can't run.
As fast today.
Also, remember that models are not conjugated.
They're not conjugated.
With the subject.
Or the time reference so grammatically?
They're very easy.
So don't say she can runs you don't conjugate run with the.
Subject she.
You don't conjugate it at all.
Of course.
Without the modal in the present simple.
She.
Runs very fast.
You would conjugate it, but with the modal.
She.
Can run very.
Fast.
Let's combine these two together.
When I.
Was younger.
I couldn't speak English, but now.
I.
Can, I'm sure.
That describes you.
So put.
Yes I can.
Yes, I can.
Put that.
In the comments.
Keep in mind that.
Could is also the polite.
Form of can could you open the window, Please notice.
The sentence structure for.
Questions we have.
The modal could.
Then the.
Subject, could you?
And then the base.
Verb Could you open?
The window.
Please.
You can of course use can can you.
Please.
Open the window could sounds more formal, more polite.
Notice the.
Placement of please.
It can come at the end of the sentence or after.
The subject.
Now let's talk about.
Permission both.
Asking for permission and giving permission you can use can can I
leave early today and then to answer.
You can say yes, you.
Can or no you can't.
I can give you permission and say you can borrow my book.
In this case, May.
Is the polite?
Form of can may I use your phone?
Sounds more formal and polite than Can I use your phone or to give permission.
You may enter.
Now what about this question?
May you open the.
Window please.
What do you think about this question?
This?
Isn't natural.
A native speaker would use could could.
You open the window please.
This is because.
May is not used.
With the subject you to ask.
For permission.
With the subject you.
To ask for permission.
Use could.
Instead.
The other subjects you.
Can use.
May.
May I open the window?
May she open the window?
May we?
May they?
Open the window, but only for you.
Could you?
Open the window.
Don't forget that.
Let's talk about possibility.
But not certainty might it might rain.
Today could.
It could.
Rain today.
Keep in mind there is no agreement to.
What?
Percentage of.
Certainty.
That might and could represent, so it might rain.
What is that?
Is that 40% chance of rain?
60 percent?
80%.
There is no general agreement.
It depends on how the speaker interprets.
It so you would just have to ask.
The person?
Well, how?
Likely is it?
Should I?
Bring an umbrella and the.
Same goes for could.
I'm sure.
You've noticed.
By now that one modal can have different meanings, so don't get confused.
By this I could.
Run.
I could run fast when I was young.
This is used for ability.
Could you?
Open the window.
Please, this is the polite.
Form of can.
It could.
Rain later.
This is for possibility.
So you have to look to the context to understand how the modal.
Is being used let's.
Talk about obligation must.
This.
Sounds forceful.
Or legally.
Required you must.
Wear a seat belt.
This is either a very forceful.
Strong recommendation from someone like your mother.
Or it is legally?
Required.
You must renew.
Your passport.
This is something a flight attendant might tell you,
and they do not allow you to fly because your passport.
Is expired.
And this is an obligation native speakers commonly.
Use have to.
When we want to sound.
Less forceful.
I have to finish this by tomorrow.
We have to start eating healthy.
Notice the.
Structure here.
We have half two.
Plus base verb if you prefer.
You can think of it as.
Have plus.
Infinitive.
Which is 2 plus base verb.
Either way, don't forget the two for lack of obligation.
Take half two and turn it into the negative.
Don't have to.
You don't have to complete this form.
You do not have to.
And then as a contraction, you don't have to complete this form or your.
Boss could say to you.
You don't have to finish the report.
There's a lack of.
Obligation for the structure.
Here notice.
Do not.
Don't.
Have to.
And then base verb, let's talk about prohibition things that are.
Prohibited.
Not allowed often.
Legally, you can.
Use cannot, and as the contraction most commonly used can't.
You can't smoke inside.
That's prohibited.
You must go outside.
That's the obligation.
You can't smoke inside.
You must.
Go outside.
You can't use your phone during the exam.
That's the prohibition.
You must turn off your phone during the exam.
That's the obligation.
Cannot as one word.
Is the correct?
Spelling The incorrect spelling is can not as two.
Words.
So cannot one word or the contraction can't.
Let's talk about must not.
Because this is a.
Strong recommendation, but it is not a.
Legal.
Requirement.
You mustn't sign the contract.
This sounds more like.
My.
Recommendation because.
I think it's a bad idea you.
Mustn't sign the contract.
You must not sign the contract.
But that.
Isn't.
An.
Obligation if it.
Were I would say you.
Can't sign the contract?
You're.
Prohibited.
From signing the contract, let's talk about advice.
You can use should to give and.
Ask.
For advice.
Or suggestions?
You should study five days per week.
You should eat more vegetables.
You.
Shouldn't quit your English.
Class.
You should not.
You shouldn't.
Ought to is used to give advice.
Or suggestions you ought.
To eat more vegetables.
But ought to is not used in modern English.
I remember my grandma using ought to.
But I never do.
If you do use it, just remember it's ought to plus base verb you.
Need that too.
To ask for advice or.
Suggestions.
Use.
Should.
Should we partner with this company?
Should I stop following J Force English?
What do you think?
Well, to reply, you can say yes you should or no you definitely shouldn't.
Hopefully you choose.
That option?
Let's talk.
About shall.
So you're at a restaurant you just finished.
Your meal.
You paid for the check.
And you?
Can say to the table, Shall we go?
Shall we go?
And that someone at the.
Table could reply back and say we shall that is the.
Only modern usage of shall.
But it.
Is very commonly used.
To suggest leaving a place.
Shall we go?
So if you want to use.
Shall I?
Only recommend you use it in that specific context.
Let's talk about will and.
Would because they are modal auxiliary verbs, so they.
Have many different meanings and uses.
Will can be used.
For spontaneous future decisions, I will help you move.
And I just decided in the moment it wasn't something I planned.
I'll help you move.
It can be used for.
Predictions often with I think, I think it will rain tomorrow it might rain it.
Could.
Rain tomorrow.
We also use.
Will for promises and commitments.
All.
Subscribe and all.
Like this video if you say that and you use will, you just made a commitment so make sure you.
Subscribe and.
Like this video SO?
You don't break your promise.
Let's talk about.
Would it's used in.
Hypothetical situations.
I would.
Go on vacation if I had more time, so just by saying I.
Would.
Go on vacation.
I know it's a.
Hypothetical, we use would for polite requests or offers.
Would you like me to make more lessons just like this?
You can say yes I would or.
No, I wouldn't we.
Also use would for past habitual.
Actions, remember.
Could was for past ability, but would is for a habitual.
Action Something you.
Repeatedly did.
In the past, when I was young, I would spend hours playing in the.
Park.
I loved it because I.
Could run really fast.
So could is the past ability, but would is the habitual past.
Action.
Here's how native speakers.
Have fun with the.
Meaning of modal verbs, Let's say you.
Ask me for something.
And you?
Say Jennifer could.
You help me?
A native could reply back.
And say.
I could and maybe I should, but.
I won't.
So the.
Questioner.
Is using could as the polite?
Form of can.
Could you help?
Me but I.
Reply and native speaker replies as a joke I could because we're using it for possibility.
I could help you.
And maybe I should?
Help you because it's an advice or.
Recommendation.
But.
I won't.
Which is a refusal.
So now you know everything.
