    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【C2】______ man from the rest of the animal 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【C4】______ cries, such as expressions of anger, fear and pleasure. But 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 enables us to divide a human utterance into【C6】______.
    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", and who can change one word and say "aircraft approaching from the north" or "tanks approaching from the west"; but a bird has a【C8】______alarm cry, which means "danger! "
    This is why the number of signals that an animal can make is very limited: the great tit is a case in point; it has about twenty different calls, whereas in human language the number of possible utterances is【C9】______. It also explains why animal cries are very【C10】______ in meaning.
【C4】
选项
答案O
解析 空格前为动词utter，而空格后为名词cries，因此空格处需填入形容词或能起到形容词作用的分词，修饰cries。空格后用such as列举了“愤怒”“恐惧”“快乐”这三种不同的情感表达，对cries进行举例说明。既然能表达出不同的情感，那这些叫声自然是互不相同的，故应选O项different。
