Directions:There are 20 blanks in the following passage.For each blank there are four choices marked A),B),C) and D) on the right side of the paper.You should choose the ONE that best fits into the passage.Then mark the corresponding letter on the Answer Sheet with a single line through the centre ; A language is a signaling system which operates with symbolic vocal sounds (语 声), and which is used by a group of people for the purpose of communication.
Let’s look at this_61_in more detail because it is language, more than anything else,_62_distinguishes man
from the rest of the _63_ world.
Other animals, it is true, communicate with one another by_64_of cries: for example, many birds utter_65_ calls at the approach of danger; monkeys utter_66_cries, such as expressions of anger, fear and pleasure._67_ these various means of communication differ in important ways_68_human language. For instance, animals’ cries do not _69_thought s and feelings clearly. This means basically, that they lack structure. They lack the kind of structure that _70_ us to divide a human utterance into _71_. We can change an utterance by _72_one word in it with ? _73_: a good illustration of this is a soldier who can say, e.g ., "tanks approaching from the north", _74_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,_75_means "danger!"
This is why the number of _76_that an animal can make is very limited: the great tit (山雀) is a case _77_point;it has about twenty different calls, _78_in human language the number of possible utterances is _79_. It also explai ns why animal cries are very _80_ in meaning.
