Hi, you can play a game in this page about Obligations and needs:)

Obligations and needs: have to / must

.
Must and have to both express obligation (a need). However, it makes a difference whether that need is external or internal.
.
Let me explain with some examples.
.
If the obligation is external (meaning someone else gave the command) you should use have to.

For example:

• I have to finish my homework because my teacher told me to.

In this case, the speaker didn’t decide to do their homework because they wanted to, but because the teacher instructed it. This is an external obligation.

Here’s another example:

• Dad said you have to eat all your vegetables.

In this example, the decision to eat vegetables is motivated by the external obligation given by dad. In both these examples, the need is motivated by outside pressure and consequences.
.
On the other hand, if the obligation is internal (meaning the speaker made the decision) you can use must. For example:
.

• I must study so I pass the test.

• I must eat this because I want to be healthier.

.
As you can see, the speaker is self-motivated in these examples.

22. Obligations and needs: have to / must

This video helped me A LOT to understand the difference between “have to” and “must”:

There are negative versions:

mustn’t: You are not allowed, you’re prohibited.

don’t have to: You are not obligated, it is your choice.

A good video that helped me with the correct pronunciation of those words is this:

Practice:

1. The teacher says: You must complete the task by tomorrow.
2. I have to wear a tie everyday. My boss told me to.
3. My mom said it’s my choice, so I don’t have to go if I don’t want.
4. I mustn’t drive. I’m only 14.

Homework:

1. I must sleep more than four hours because I’m feeling too tired every day.
2. I have to go shopping tomorrow, there isn’t enough milk for the cake.
3. You must wear your face mask every time you go out.

I must clean up my room I have to eat more healthy because my doctor told me to.

• If I want to improve my English, I must study every day.
• I need to get up early, so I mustn’t go to bed late.
• According to my doctor, I have to leave the sweets.
• I don’t have to go to the bank, I can pay my bill on the website.
