An outstanding example of hardwired capabilities with great flexibility for programming by us is language. Specialists agree that 'the human brain genetically programmed for language 【1】______ development,' and that 'speech can be explained only on the basis of an innate language-processed capacity within our brain. Unlike 【2】______ the rigidity that is displayed in the instinct behavior. of animals, 【3】______ therefore, there is tremendous flexibility in a human's use of this 【4】______ hardwired capacity for language. A specific language is not hardwired into our brains, and we are 【5】______ preprogrammed with the capacity for learning languages. If two language are spoken in the home, a child can learn both. If exposed 【6】______ to the third language, the child can learn it also. One girl was 【7】______ exposed to a number of languages from babyhood. By the time she was five she spoke eight fluently. In the view of such innate abilities【8】______ it is not surprise that a linguist said that chimpanzee experiments 【9】______ with sign language 'actually prove that chimps are capable of even 【10】______ the most rudimentary forms of human language.' 【M1】
