B
Many people believe that goldfish only have a seven-second memory. But Roy Stokes, a 15-year-old schoolboy from Australia Science and Mathematics School has just finished an experiment to tell us that it is not true. He shows everybody that goldfish are smarter than we think.
“I don’t believe that they have a seven-second memory because animals need their memories, so they can know where the food is,” he said.
He did the experiment on a small tank of goldfish. “I decided to get a red sign and just feed them next to the sign. Every day I put it in and dropped food around it,” he said.
“At first they were a bit afraid of it, but by the end of the three weeks, they were actually almost coming before I put the food in.”
After leaving the goldfish alone for a week, Roy put the red sign in the tank again.
“They remembered perfectly well,” he said. “Sometimes they actually came faster than before.”
The goldfish showed that they not only could retain(保留) information, but also had the ability to get it back at a later date.
Colum Brown, a researcher at Macquarie University in Sydney, has studied fish behavior for more than ten years. He says his studies show that fish are intelligent and they know how to avoid enemies and catch food like any other animals. As an experienced expert, Colum thinks that Roy's experiment is really good.
( )4. Roy began his research by ______.
A. discussing with his classmates
B. making friends with goldfish
C. asking his teacher for advice
D. questioning a popular belief
( )5. The right order of Roy's experiment should be ______.
①put the sign back into the tank
②feed the goldfish next to the sign
③leave the goldfish alone for a week
④take out the sign
⑤put a red sign into the tank
⑥find a tank of goldfish
A. ⑥⑤②④③①
B. ⑥④⑤③①②
C. ⑥①⑤③②④
D. ⑥⑤③②④①
( )6. Roy's experiment shows that ______.
A. goldfish have a seven-second memory
B. goldfish are smarter than we think
C. goldfish can avoid enemies like any other animals
D. goldfish cannot catch food like any other animals
( )7. The passage is probably taken from ______.
A. a mathematics book
B. a historic story
C. a science magazine
D. a travelling diary
