问题 A language is a signaling system which operates with symbolic vocal sounds, and which is used by a group of people for the purpose of communication.
Let’s look at this【C1】______in more detail because it is language, more than anything else, that distinguishes man from the rest of the【C2】______world.
Other animals, it is true, communicate with one another by means of cries: for example, many birds utter【C3】______calls at the approach of danger; monkeys utter different cries, such as expressions of anger, fear and pleasure.【C4】______these various means of communication differ in important ways from human language. For instance, animals’ cries do not【C5】______thoughts and feelings clearly. This means, basically, that they lack structure. They lack the kind of structure that【C6】______us to divide a human utterance into words.
We can change an utterance by【C7】______one word in it with another: a good illustration of this is a soldier who can say, e. g. , "tanks approaching from the north",【C8】______who can change one word and say "aircraft approaching from the north" or "tanks approaching from the west"; but a bird has a single alarm cry, which means "danger!"
This is why the number of【C9】______that an animal can make is very limited: the great tit(山雀)is a case in point; it has about twenty different calls. In human language the number of possible utterances is【C10】______. It also explains why animal cries are very general in meaning. [br] 【C8】
