Vette first used voice commands and treats to teach the dogs how to turn a steering wheel and how to change gear (换挡). The dogs’ ride only accelerated up to 7.5 miles an hour, and trainers could stop the auto using a remote control. GOLDEN ZEBRA Kailua-Kona, Hawaii Zoe the zebra’s markings are special. The animal has white and golden stripes. Zoe’s appearance resulted from a rare condition called amelanosis (黑素缺失症). Her body doesn’t make enough melanin, the substance in an animal’s skin and hair cells that produces color. “Only 25 other golden zebras are known to exist in the world,” says Ann Goody, who runs the wildlife refuge where Zoe lives. In the wild, life may be difficult for animals with amelanosis because predators (捕猎者) can easily spot them. But Zoe is protected at her refuge. COCKATOO MAKES TOOLS Vienna, Austria When Figaro the cockatoo spots food lying just out of reach from his cage, he builds a tiny wooden tool to sweep the tasty prize in his way.

So he flew away and returned with a small branch, slipping it through the fence to slide the stone toward him. Wondering if he would do it again, scientists placed a nut exactly where the stone had been. This time, Figaro pulled out a small piece of wood in his cage and dragged the nut toward him. 21. If Zoe the zebra is set free in the wild, she will _____. A. meet no natural predators B. not get along with other zebras C. manage to make enough melanin D. be easily found for her appearance 22. What’s special about
