Read the following text and mark the statements as T (true), F (false) or DS (doesn't say).
Since school is the place where you spend a good part of your day, it's a good idea to have a few rules regarding classroom etiquette in mind.
To begin with, it's always nice to greet your teacher and the other students when you walk into the classroom. If you go to class after the lesson has already started, it's polite to apologise to your teacher. During the lesson, you need to respect your classmates, as well as your teacher. That means you should pay attention to others when they're speaking to the whole class, and you shouldn't talk to those next to you while the teacher is trying to explain something.
Of course, all this doesn't mean that the classroom environment needs to be strict and boring. Your teacher will certainly appreciate it if you have something funny to share with the rest of the class. Also, if you have any fresh and creative ideas about a class project or trip, your teacher will be more than willing to hear about them. After all, teachers run out of ideas too! Remember, teachers were once students themselves, and they know very well that every now and then, the class needs to do something different from their usual routine and, above all, they know that learning should be fun!
41 You should never talk when entering the class. .......
42 If you are late, you need to bring a note from your parents. .......
43 You should never talk in the classroom. .......
44 It's OK to tell a joke in the classroom. .......
45 You should feel free to make any suggestions related to school matters to your teacher. .......
