Smarter than We Thought
It's a popular belief that fish can't remember anything for longer than seven seconds.
It may seem sad to think that they don't remember what they've eaten or where they've been, and they don't recognize you or any of their friends—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 recent study has found that fish have much better memories than we used to think. In fact, certain kinds of fish can even remember events from as long as 12 days ago, BBC reported.
In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again.
Researchers used computer software (软件)to monitor the fish's movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.
In fact, scientists had been thinking for a long time that African cichlids might have a good memory.
An earlier study showed that they behaved aggressively (攻击性地) in front of certain fish, perhaps because they remembered their past fights. But until the latest findings, there was no clear evidence (证据).
Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to live in the wild.
"If fish are able to remember that a certain area has 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.
For a long time, fish were placed far below chimpanzees (黑猩猩), dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence (智力).
So next time you are watching your pet fish from outside the tank, perhaps you should feel closer to them——they may remember who you are.

Everyone wears shoes. We wear them every day to avoid{#blank#}1{#/blank#}our feet. We can buy shoes in many places. But maybe most of us don't know about the process of shoemaking because now most shoes are produced by{#blank#}2{#/blank#}. Here I will tell you how to make a pair of shoes.
The first step is drawing a design. Next, the shoemaker will use paper to make a pattern. Then the shoemaker draws the pattern on some{#blank#}3{#/blank#}like leather(皮革)and cloth. After that, he cuts the leather with scissors and then he will sew(缝) and glue the leather pieces together.
Then the shoemaker connects the pieces to the insole(鞋内底).The insole is the part of the shoe that{#blank#}4{#/blank#}your feet. Next, the shoe is heated to make the leather soft so it can be shaped. Then the shoe goes in an oven. This helps it keep{#blank#}5{#/blank#}form. At the same time the shoemaker works on the lower(较低的) parts of the shoe. When all the parts are ready, the shoemaker glues and sews them together. After these steps, a pair of shoes is completed.
