🎯 Lesson Goal
In this lesson, you will learn how to use expressions of obligation and necessity to talk about rules, advice, and requirements in everyday situations such as work, study, and travel.
🧠 Grammar Focus
We use modal verbs and expressions like must, have to, need to, and should to show obligation or necessity. Use must for strong rules or requirements by yourself or others. Have to shows external rules or needs. Need to shows a necessity or requirement. Should gives advice or recommendations. Use must not or don’t have to for prohibition or no obligation. Examples: You must wear a uniform at work. I have to finish my homework today. She needs to see a doctor. You should take a rest. We must not be late to the meeting. He doesn’t have to come if he is busy.
📖 Short Reading
Anna works as a teacher. At her school, she must arrive before 8:00 a.m. every day. She also has to prepare lessons and grade papers after classes. Sometimes, she feels tired but knows she needs to finish her work. Her students should listen carefully and complete their homework on time. Anna says, "You must not talk during the lessons because it distracts others." On weekends, Anna does not have to work. She should relax and spend time with her family. This balance helps her stay healthy and happy.
