There is a popular belief that goldfish only have a three-second memory. But a 15-year-old schoolboy from Adelaide has just finished an experiment(实验)to tell us that it is not true. He shows everybody that the goldfish is smarter than we think.

“I don’t believe that they had a three-second memory because animals need their memory, so they build up over time a knowledge of where the food is,” said Roy Stokes, a student at the Australian Science and Mathematics School.

He did the experiment in small tank(鱼缸)of goldfish. “I decided to get a bit of red Logo and just feed them next to that. Every day I’d put it in and spread food around it.” He said.

“At first they were a bit scared of it, but by the end of the three weeks, they were actually almost coming before I put the food in.”

After leaving the fish alone for a week, Rory placed the red Logo block in the tank again.

“They remembered perfectly well,” he said.

“They actually had a time faster than the average of the three feeds before I left.”

The goldfish showed that not only could they store information, they also had the ability to get it back as a later date.

Culum Brown, a research fellow at Sydney’s Macquarie University, has studied fish behavior for more than ten years.

He says his studies of Australian native fish show fish were intelligent creatures that know how to avoid enemies and catch food like any other animal.

“The thing that I really liked about Rory’s experiment is he not only got that classical conditioning going but the fact that he could get them next just to that specific coloured market. I thought it was really good.” He said.

A. Rory’s research was highly praised by experienced experts.

B. Rory’s experiment failed to meet the scientific standard.

It was Saturday again. Grace and Karen disliked Saturdays. That was another thing the twins had in common. They shared the same clothes and tied their hair in the same manner. In fact, it was hard for their classmates and teachers to tell them apart sometimes.

Unlike their classmates, they had to get up early at seven every Saturday to prepare for their lessons. Grace had to attend the art lesson and Karen had to attend her ballet lesson. “How I wish I could do something different today,” said the twins with one voice. All at once, an idea came to Grace and Karen at the same time. “How would you like to be me for a day?” they asked each other. It seemed like a wonderful plan to them. After giving each other a description of their own friends, Grace put on Karen’s ballet dress while Karen put Grace’s brushes and paints into her bag. Then they left for their classes.

When the art lesson started, Karen was lost. Unlike Grace, Karen was poor at drawing. When the art lesson finally ended, Karen didn’t dare to hand in her work.

Meanwhile, Grace was struggling in the ballet class as well. As she had no idea about the dance steps, she had to follow her classmates blindly. As a result, she kept knocking into them. Their ballet teacher became impatient with her, “Karen, you should remember the basic steps. You can’t rely on copying what others are doing.”

When Karen and Grace got home, they were tired out. They decided that they would never try to be someone else they were not. It seemed that the grass was not always greener on the other side.

1.Did Grace and Karen like Saturdays?

2.When did the twins get up on Saturdays?

3.What was the twins’ plan when they decided to do something different?

4.How did Karen feel at the beginning of the art lesson?

5.Why did the ballet teacher become impatient?

6.What does the underlined part “the grass was not always greener on the other side” at the end of the story try to tell us?
