We are living in the same world.We like it very much.All of us hope it can be better.Here are some tips for a better world.
    Don't post pictures.
    Many parents post pictures of their children on social media.I sometimes think this is a bit embarrassing（尷尬的）or even dangerous.If the wrong people see the information on the pictures，it could cause trouble.Luckily，I'm glad social media wasn't around when I was young!
    Less roadside vendors!
    On my way home after school，I often see roadside vendors（路邊攤販）selling food.Many students and adults buy their food because it is cheap and delicious.But I think these vendors and their food do harm to both our environment and health.They leave rubbish everywhere and it is smelly.
    No fire，please!
    The other day，I saw some students playing with matches（火柴）and making a fire.This is very dangerous!You might think matches are small and can't cause trouble. But even a little spark（火星）can cause a big fire-burning down buildings and forests. Tragedies（悲劇）like this happen every year.We should use fire carefully and stay away from it when we can.
    （5）________
    In our school，students do class chores（值周）from Monday to Friday.We clean the floors and blackboards.So we're often left with a big bag of rubbish in the hallway.Some people throw it into the rubbish bin.But they sometimes aren't careful about it and rubbish may be left on the ground.So we should go closer to the rubbish bin to make sure that all the rubbish is thrown away in a correct way.It may seem like a small step，but it's important.
