将下列单词或词组填入空格。每词只能填一次，用A,B,C等表示

Anyone who has ever come across a parrot in a pet store can prove the fact that they    1   imitate（模仿） what humans say, but that they can actually produce human speech. Many people think this is an uncertain point since they believe that birds can’t    2   talk, much less hold conversations. For others, including some experts, parrots and a few   3  birds are capable of verbal communication（语言交流）. Parrots are language learning animals and are physically able to recreate   4    in the human language. 

     Except that parrots can speak, some else have also shown signs of     5   intelligence. An African Gray Parrot named Alex had a vocabulary of some 150 words and could do simple math.    6   , it could distinguish（辨别） seven colors and five shapes, and   7    the meaning of zero. Overall, he had the intelligence of a five-year-old human. This means that parrots having conversations with humans is no longer a   8   that is strictly（严肃地） for the birds.
