应急救援演习分室内演习和（）演习。

Our world is full of rules. Everyone needs to obey them. But      your idea about your school rules? Now many students like to talk about the rules that they have      . At their school, they      wear uniforms every day. The problem is that all the students think the uniforms are        . They think young people should look smart and so they would like to wear their own clothes.      , their teachers believe that if they did that, they would think       of their clothes than their study.       the students disagree. They would feel more comfortable and that is good for      . If they can’t do that, they        design their own uniforms. That would be a good way to      both teachers and students happy.

It’s also probably a good idea for parents to allow teenagers to study in groups during the evening.  Although they get        sometimes, they can learn a lot from each other. They also think that vacations should be longer. At present they’re too      . Longer vacations would give them time to do things like volunteering. On Friday afternoons, many students are sleepy after a long week of classes. They think it’s better to have Friday afternoons        to volunteer and help others.        , it is helpful for students to go to an old people’s home to sing and perform a play for them. It will help them understand the meaning of love. It’s also better to volunteer at the local hospital. It would be a good         for them because some of them want to be doctors when they grow up.
