It's a common belief that fish can't remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don't be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.
In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after such a long break the fish sill went to the same place where they first got food.
In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence until the latest findings.
Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. "If fish are able to remember that a certain area contains(容纳) safe food, they will be able to go back to that area without putting their lives in danger," lead researcher Trevor Hamilton told Live Science.
So next time you are watching your pet fish from outside the tank, perhaps you should feel close to them-they may remember who you are.

In Shanghai City, when people throw away wet waste, they must take the wet waste (mainly food waste) out of the rubbish bag first. Then, they throw the rubbish bag into another trashcan(垃圾桶). This is not easy to do.
Shi Yuan is a 14-year-old student from Shanghai Wenlai Middle School. One rainy day in May, 2019, when he was throwing away wet waste, he got food waste all over his trousers. Then, he decided to do something about this. He made a special rubbish bag for wet waste. The bag has a band of adhesive tape(粘贴带). When one end of the tape is open, the bag turns upside down by itself. Then, people can easily throw wet waste into the trashcan. Shi’s idea won him a prize in the Shanghai Adolescents Science & Technology Innovation Contest. So far, he has sold over 2 million bags online. And on May 4, 2020, he began to sell his bags in 11 supermarkets in Shanghai.
“Like many other kids, I’m also busy with homework and I like to play. The only difference is that I like to find ways to make life easier,” Shi said.
