一周七天英语趣味记忆（学生英语时光Goldfish）

Goldfish have a short memory. Deserts are alwayshot. Do you think so? This is not correct! Popular Science magazine picks (挑选) some answers that sound correct, but are actually wrong. Let’s take a look.

Goldfish are the world’s most popular pet fish. Many people think goldfish haveonly a three-second memory. Is this true?

Scientists say goldfish are smarter than people think. In a simple experiment (实验),they keep a small tank of goldfish. They put a red Lego brick in the fish’stank every time they feed the fish. At first, the goldfish are a bit scared ofit. But after three weeks, they swim to the red Lego to wait for their food.

Then, the scientists leave the fish alone (不理)for a week. When they put the red Lego in the tank again, the fish remember it.Goldfish have a good memory. They can remember things for up to five months.

Think about this

If goldfish are smart, is it cruel to keep them in tiny fish tanks?

Scientists suggest (建议)that goldfish keepers should make their fishtanks interesting so that their fish will be happy.
