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 self-reflection 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 8-foot-square 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 elephants were intelligent, but now we can talk about their intelligence in a better way.”

　　全國卷高考閱讀理解真題答案解析：

　　1.B　細節理解題。根據第二段第一句可知，通過研究動物是否在鏡子中識別自己可以測試它們的自我意識。

　　2.D　推理判斷題。根據第二段最后一句可知，作者提到猿和海豚是因為它們和人一樣可以識別鏡中自己的形象，是人們已知的有智力的動物;再根據第三段，一個亞洲象也通過了該測試，也加入到有智力的行列里，故選D項。

　　3.B　細節理解題。根據倒數第二段，三個大象中只有Happy通過了鏡子測試，也就是說只有她能識別鏡中自己的形象，因此這是她有別于其他大象的地方，故選B項。
