高中英语人教版必修五Unit 4 Making the news同步练习 (2)
People can often see a talking parrot on a TV show, in a movie, or even in someone's home. The parrot has learned (copy) sounds that people make. Dolphins, bats, and some other animals also copy sounds. Now we can add elephants this list of copycats (盲目模仿者).
Dr. Joyce Poole is an expert,studies the sounds of elephants. While she was in Kenya, she would hear strange noises (make) by Mlaika after sunset. Mlaika was 8-year-old African elephant and it lived near a highway.
Dr. Poole says that she couldn't tell the (different) between Mlaika's call and the (distance) truck noise. Why did it copy the sounds of the trucks driving by? Animals that are able to copy sounds may enjoy (practice) new sounds. When they (keep) outside of their natural environment, they may copy unusual sounds.
So far Dr. Poole (spend) 18 years with two female Asian elephants. Asian elephants make sounds like birds to talk with one another.
Parrots, dolphins, humans, and elephants show that being a copycat is one way that animals and people make new friends and keep old ones.
