Modal verb have to

Hello, boys and girls! My name is Bobby.

And my name is Tobby. This is our friend Mobby.

Welcome to our lesson.

Today we would like to tell you one scary story.

It’s about three little boys and one evil dragon.

It was Halloween night! On that day the boys put their costumes on and left the house. Pixie chose the costume of a Viking, Rico decided to be a clown and Scotty chose the costume of a vampire. The boys wanted to visit all the houses in their neighborhood. They usually knocked at the doors and asked for sweets. On that day they decided to start with the house which was farther than the others. The boys went straight to that house. They came closer to the door and suddenly a scary dragon appeared in front of them.

Who are you? What are you doing here?

Oh, wow! Guys, look at him! He looks like a real dragon!

I’m a real dragon!

Yeah, right!

Where did you get your costume?

It’s not a costume! I’m a dragon!

No, you’re not!

Wait, guys! Real dragons can shoot out flames.

Yeah! Prove that you are a real dragon!

Oh my God! It’s true! You are a dragon!

Guys, run!

No! If you make a move, I will burn you to the ground!

Okay, we won’t go anywhere! But what do you want from us?

I need your help!

We have no reason to help you! You will burn us anyway!

No! I will burn you if you don’t help me!

Okay! We have nothing else to do but help you!

What kind of help do you need?

Well… My son studies at the dragon’s school. And yesterday he asked me to help him with his homework. It’s connected to some modal verb “have to”.

Oh, it’s easy!

Easy? I don’t even know what a modal verb is!

Don’t worry! We will explain this rule to you.

So today in the lesson we will:

revise the definition of the term “modal verb”;

talk about the modal verb “have to”;

And

put the knowledge into practice.

Let’s start with the definition of the term “modal verb”.

Modal verb is a verb which we use to express:

Necessity (необходимость)

Obligation (обязательство)

Duty (долг)

Permission (разрешение)

Advice (совет)

Possibility (возможность), etc.

Modal verbs need to be accompanied by another main verbs.

For example:

Joan, you should eat more vegetables.

Or

Zoe, you can take a piece of cake.

(In these two sentences we used the modal verbs “should” and “can”, which are accompanied by the main verbs “eat” and “take”).

Now let’s talk about the modal verb “have to”.

The modal verb “have to” is translated as “надо, должен, вынужден, обязан”.

“Have to” is used to show that we must do something.

For example:

Children have to go to school.

Or

I have to get up at 5 o’clock every day.

Now we will tell you how to form sentences with the modal verb “have to”.

To form positive sentences we need to put the subject in the first place.

The subject is translated as “подлежащее”.

For example:

The girls

Or

Mike

Then we need to use “have to” (if we have such pronouns as: I, we, you, they) or “has to” (if we have such pronouns as: he, she, it).

For example:

The girls have to

(In this sentence we can replace the word “the girls” with the pronoun “they”).

Or

Mike has to

(Here we can replace the word “Mike” with the pronoun “he”).

After that we need to use the base form of the main verb.

For example:

The girls have to wash the dishes.

Or

Mike has to go to hospital.

To form negative sentences we need to put the subject in the first place.

For example:

The girls

Or

Mike

Then we need to use the auxiliary verb “do” or “does” with the particle “not”.

We use “do” with the pronouns I, you, we, they.

And

We use “does” with the pronouns he, she, it.

The short form of “do not” is “don’t”.

And the short form of “does not” is “doesn’t”.

Now look at the examples:

The girls don’t

Or

Mike doesn’t

After that we need to use “have to” with the base form of the verb.

For example:

The girls don’t have to wash the dishes.

Or

Mike doesn’t have to go to hospital.

And to form questions we need to put do or does – in the first place. After that we need to use the subject.

For example:

Do the girls

Or

Does Mike

Then we need to use “have to” with the base form of the verb.

For example:

Do the girls have to wash the dishes?

Or

Does Mike have to go to hospital?

We’ve told you everything about the modal verb “have to”.

Now we will help you to do the homework.

Let’s read the task.

Fill in the gaps with have to, has to, don’t have to, doesn’t have to.

And the sentences are:

Sick people … stay in bed.

Let’s check.

You … go to school if you are sick.

The girls … go to the library now.

Felix … get up early, because it’s Saturday.

You … buy me a sandwich, because I’m not hungry.

Let’s check.

Great! Your homework is done!

Thank you for your help, boys!

You’re welcome.

Now you can go! I won’t burn you!

Oh, thank you! What about sweets? It’s Halloween!

What? Sweets? I don’t have any sweets! Go away or I will change my mind!

Oh, we are so sorry! It was a silly question!

Thank you for your kindness! Bye.

The boys ran away as fast as they could!

That’s all for today, boys and girls!
