(A)
Have you seen sharks in the West Lake? Two “sharks” swim fast there. Their bodies are dark and shiny. Their fins(鱼鳍)
cut through the water like knives. But they aren’t real sharks. They’re robots!
These robot sharks help visitors find lost things in the water. Why do they choose sharks? Sharks are great swimmers. Two-thirds of their bodies are very flexible(灵活的). This helps them swim fast and turn quickly in water. That’s just what robot fish need! Underwater, the robot sharks move easily through rocks and plants.
They can’t swim like real fish yet. But scientists are improving(改进) them. When a robot fish swims in a pond, goldfish often follow it. Maybe they think it’s their new friend!
