Задание 2. Сделать задание к тексту.
Only humans have a spoken, symbolic language; scientists have long thought that nonhuman primates had much less sophisticated communication systems. True, but chimpanzees use gestures and many voice sounds in the wild, while other apes use sounds to communicate territorial information. Chimpanzees seem to have a natural talent for learning symbolic language under controlled conditions. A famous
chimpanzee named Washoe was trained to communicate with humans, using no less than 175 sign language gestures similar to those of the American Sign Language. After more than a year Washoe could associate particular signs with activities, such as eating and drinking. Another chimpanzee named Sarah was taught to read and write with plastic symbols and acquired a vocabulary of 130 different words, to the extent that she obeyed sequences of written instructions given with the symbols. But such experiments in communication with primates are a far cry from the versatility and grace of human speech.
