4. I’m in a hurry. I
   

In English, when you’re in a hurry and need to express urgency or necessity, the modal verb “must” is often the go-to choice. For example, if you’re racing against the clock to get to school, you might say, “I must hurry to avoid being late!” It’s all about showing that the action is essential!

On the other hand, “has to” is used to express obligation, but it leans more towards someone else requiring you to do something. If your teacher says, “You have to be on time,” it implies there’s an external pressure. So remember, if you’re feeling the urgency yourself, “must” is your friend in that context!
