Every school has rules for students.The rules are different(不同 的)from one school to another.Here are some funny school rules.
In Japan,most schools ask their students to wear uniforms.They also ask girls to wear white socks and boys to cut their hair short.And some Japanese schools also tell students not to go to the movies or leave home at night.They also don't let the students play video games without permission(允许)from the school.
In America,at some schools,students must have a pair of indoor shoes to change(改变) into at school every day.This makes sure students won't fall over on the wet floors and keeps the schools clean.
Students can't chew gum(嚼口香糖)in many American school buildings, because it is difficult to clean up.And if students chew gum in class, they may not study well.
In Britain,strange hairstyles are not allowed(被允许) in some schools.But they might allow students to wear certain hairstyles during the World Cup years.Two students had a special hairstyle during 2016 World Cup.But their school asked them to change the hairstyle after that because the school said the rules had changed since then.
You need some bread and milk. But half an hour later, you leave the supermarket with a trolley of food. What games do supermarkets play to make us spend so much money?
The games usually start before you walk in. When we walk past the supermarket entrance. We can smell warm, fresh bread. That makes us want to eat and then buy lots of food, not just bread.
▲And, of course, a small basket would be fine, but most are trolleys. And of course a trolley is big and it looks poor and strange with just one or two products in it. So we may put lots of products into it. You see, supermarket trolleys are getting bigger.
What's more, what about the music? Most supermarkets don't play fast songs. Because they want you to spend more time and money there. And you won't be in a hurry when the supermarket is busy. And be careful with queues at the checkouts. Sometimes, these are just to make you buy something from the checkout shelves next to you while you are waiting.
So, next time you go into a supermarket, can you come out just with the things you want? Think about the games!

It may also help those with depression and dementia (抑郁症和痴呆症). ___②___ The lead scientist, Marie Banich, said, "It may sound surprising that people can decide what and how they forget. "

She said, "We have control (控制) over the ability to take information away from…our thoughts. "___③___ However, although we can control what and how we forget, the act of forgetting is difficult and needs a lot of energy (能量). Another scientist, Sara Festini, agreed. She said, "We've found that the act of forgetting no-longer-relevant (不相关) information from the mind is good for people, but it doesn't happen by the brain itself. " ___④___ Researchers will now look at why we forget recent things, like where we left our keys.
