Whether the eyes are "the windows of the soul" is debatable;that they are intensely important in interpersonal communication is a fact.During the first two months of a baby's life,the stimulus that produces a smile is a pair of eyes.The eyes need not be real:a mask with two dots will produce a smile.Significantly,a real human face with eyes covered will not motivate a smile,nor will the sight of only one eye when the face is presented in profile .This attraction to eyes as opposed to the nose or mouth continues as the baby matures.In one study,when American four--year--olds were asked to draw people,75 percent of them drew people with mouths,but 99 percent of them drew people with eyes. In Japan.however,where babies are carried on their mother's back,they do not acquire as much attachment to eyes as they do in other cultures.As a result,Japanese adults make little use of the face either to encode (...) or decode meaning.In fact,Argyle reveals that the "proper place to focus one's gaze during a conversation in Japan is on the neck of one's conversation partner." The role of eye contact in a conversational exchange between two Americans is well defined:speakers make contact with the eyes of their listener for about one second,then dance away as they talk;in a few moments they re-establish eye contact with the listener or reassure themselves that their audience is still attentive,then shift their gaze away once more.Listeners,meanwhile,keep their eyes on the face of the speaker,allowing themselves to glance away only briefly.It is important that they be looking at the speaker at the precise moment when the speaker reestablishes eye contact:if they are not looking,the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will stop the conversation.Just how critical this eye contacting is to the maintenance of conversational flow becomes clear when two speakers are wearing dark glasses:there may be a sort of traffic jam of words caused by interruption,false... The author is convinced that the eyes are _ . A) of extreme importance in expressing feelings and exchanging ideas B) something through which one can see a person's inner world C) of considerable significance in making conversations interesting D) something the value of which is largely a matter of long debate

And in reading books of this kind the important thing is _ ; to try to grasp what the writer is going to tell you in the book as a whole. This is impossible if you stop and think over the meaning of every single word which happens to be unfamiliar.

You may even prevent yourself from understanding the story as a whole by doing this. When you are reading books of this kind, therefore, you will usually have to depend mainly on the context to help you. If you meet an unfamiliar word, do not let it take too much of your attention from the main idea of the story.

A) You can learn a lot from the study of a language. B) Guess words' meanings according to context. C) Reading for pleasure is important. D) Reading skills for books like novels, plays and so on
