I want to b a modl studnt. What shall I do? 　 　

I should b polit. I should study hard. I should capful and hlpful. I should walk in th corridors. I should throw rubbish in th bin. I should b quit in th library. I shouldn’t walk and run on th grass. I shouldn’t throw rubbish on th floor. I shouldn’t run in th corridors. I shouldn’t fight. I shouldn’t b noisy in th library. 　

How about you?
