阅读下面短文,根据其内容写一篇60词左右的内容概要。
For those who study the development of intelligence in the animal world,selfawareness is an important measurement.An animal that is aware of itself has a high level of intelligence.
Awareness can be tested by studying whether the animal recognizes itself in the mirror,that is,its own reflected image.Many animals fail this exercise bitterly,paying little attention to the reflected image.Only humans,and some intelligent animals like apes and dolphins,have been shown to recognize that the image in the mirror is of themselves.
Now another animal has joined the club.In the Proceedings of the National Academy of Sciences,researchers report that an Asian elephant has passed the mirror selfreflection test.
“We thought that elephants were the next important animal,”said Diana Reiss of the Wildlife Conservation Society,an author of the study with Joshua M.Plotnik and Fans B.M.de Waal of Emory University.“With their large brains,” Reiss said,“elephants seemed like cousins to apes and dolphins.”
The researchers tested Happy,Maxine and Patty,three elephants at the Bronx Zoo.They put an 8footsquare mirror on a wall of the animals’ play area (out of the sight of zoo visitors) and recorded what happened with cameras,including one built in the mirror.
The elephants used their long noses to find what was behind it,and to examine parts of their bodies.
Of the three,Happy then passed the test,in which a clear mark was painted on one side of her face.She could tell the mark was there by looking in the mirror,and she used the mirror to touch the mark with her long nose.
Diana Reiss said,“We knew

【答案】
The researchers who study the development of intelligence in the animal world found that an animal with a high level of intelligence is aware of itself.They tested awareness by studying whether the animal recognizes itself in the mirror.Only humans,and some intelligent animals like apes and dolphins can pass the test.But now an Asian elephant also has passed the mirror selfreflection test.The researchers can talk about the intelligence of elephants in a better way.
