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.

Years ago, if a person had some problem in his life, he might go home and write in his diary. Now he might go onto the Internet and write about them in a blog.

Differences between a blog and a diary

Usually, a person thinks of his diary as a book full of secrets. He does not want to share. But in the blog, anyone can read what he writes.

I have a little sister, and sometimes I go onto the Internet to read her blog. She writes about swimming practice and not studying enough for her chemistry exam. When I was her age, I wrote about the same things, but only in my diary. Then, after I finished writing, I would put my diary in a secret place because I was worried that my sister might read it!

Problems with blogging

The biggest problem with blogging is that anyone can read what you write. If I was angry with a friend and wrote something bad about her in my diary, she would never know. However, if my sister wrote something bad about a friend, that friend might read her blog and get angry. Because we do not always think about things carefully before we write about our days. It is easy to hurt others’ feeling in a blog. So we have to be very careful about what we write.

Keeping in touch with (保持联系)friends

Blogging has both good and bad points, of course. People choose to blog because they know that their friends will read what they write.

If I was feeling sad one day and wrote in my diary “Nobody cares about me,” no one would know about it. However, if my sister wrote the same sentence in her blog, her best friends would quickly reply and tell her how much they like her. Blogs help people keep in touch with their friends and know what the people around them and doing.

Blogs are a very good way to write about daily life, if people are careful aout what they write. However, I still like writing better in my diary!
