阅读理解Under normal conditions the act of munication requires the presence of at least two persons: one who sends and one who receives the munication. In order to municate thoughts and feelings, there must be a conventional system of signs of symbols which mean the same to the sender and the receiver.The means of sending munications are too numberous and varied for systematic classification, therefore, the analysis must begin with the means of receiving munication. Reception of municatio isachievedbyourenses.Sight,hearing,andtouch play the most important roles. Smell and taste paly very limited roles, for they cannot receive intellectual expression from fully developed systems of signs and symbols         Examples of visual munication are gesture and mimicry (模仿). Although both frequently ac- pany speech, there are systems that rely solely on sight, such as those used by deaf and dumb per- sons. Another means of munication visually is by signals of fire, smoke, flags and flashing lights. Feelings may be simply municated by touch, such as by handshaking or backslapping, although a highly developed system of handstriking has enabled blind, deaf, and dumb persons to municate intelligently. Whistling to someone, applauding in a theater, and other forms of munication by sound rely upon the ear as a receiver. The most fully developed form of auditory munication is, of course, the spoken language.The means of munication mentioned so far have two features in mon: they last only a short time and the persons involved must be relatively close to each other. Therefore, all are restricted in time and space.1.The author explains he will deal with reception of munication first because   A.munication actually takes place when the message is receivedB.there are more means of receiving than of sending cmmunicationC.reception of munications involves use of the sensesD.it is difficult to organize by type the means of sending munication2.Persons who cannot see, hear, or speak are able to municate through a system of A.gesturing      B.handshaking      C.backslapping      D.handstriking3.A form of visual munication often used with a type of auditory municati      A.gesturing    B.handshaking       C.backslapping      D.handstriking4.The author specifically mentions that speech is A.often used when munication by touchB.necessary for satisfactory munication by gestureC.the only highly developed system of municationD.the most developed form of munication based on hearing5.Which of the following statements about munication by touch is true?
