[阅读题,10分] All of us can change our behaviour to fit different situations.We are often noisy at weddings and sympathetic at funerals.Our table manners are not the same at a picnic as in a restaurant.When speaking with people,we feel free to interrupt close friends but tend to listen to our employers until they finish.If we don’t make such adjustments(调整),we are likely to get into trouble. From one point of view,language is behaviour;it is part of the way we act.And like every other kind of behaviour,it must be adjusted to fit different contexts or situations where it is use
For instance,among people who are used to a writing system,there is one adjustment everyone makes:they speak one way and write another way.Speakers can stop in the middle of a conversation and repeat themselves if they sense that they are being misunderstood;writers often go back over their writing to see that it is clear,which is,however,before the communication occur.Once writers have passed their writing to someone else,they cannot change it. Speakers can use intonation(语调)，stress(重音)，and pauses to help make their meaning clear.A simple sentence like “John kept my pencil” may mean,by a shift in the stress and intonation patterns,either John rather than someone else kept the pencil,or John kept rather than just borrowed the pencil,or it was a pencil rather than anything else that he kept.Writers,on the other hand,have their special tools of various punctuation(标点) marks,capitals,italic(斜体) letters,and so on.Skillful writers could also change the word order of a sentence.So“Cindy only had five dollars” could be turned into “Cindy had only five dollars” to mean Cindy had no more than five dollars,or into “Only Cindy had five dollars” to mean nobody but Cindy had five dollars. 1.The main purpose of the first paragraph in this passage is to _______.
