In our daily life, we often use 情态动词 to express different meanings. For example, when we say "You must wear a seatbelt in the car", it means it is necessary to do so. And when we say "You may choose any book you like", it gives someone permission.
Can and could are also commonly used. We use can to talk about ability in the present. For instance, "I can speak English well". Could is the past form of can and is often used in polite requests or to talk about past ability. "Could you pass me the salt?" is a polite way of asking.
Mustn't means it is not allowed to do something. For example, "You mustn't smoke in public places". Needn't means there is no need to do something. "You needn't bring an umbrella. It won't rain today".

Rules in My School
There are many rules in my school. First of all, we must wear school uniforms every day. This makes us look tidy and shows our school spirit. We can't be late for class. Being punctual is very important. In the classroom, we must listen carefully to the teacher and can't talk loudly. We should also keep the classroom clean. We must put the rubbish in the bin. During the break, we can play games on the playground, but we mustn't run around in the teaching building. These rules help us to study and live better in school.
