Speech certainly came before the discovery of fire. We still tend to use speech not for conveying messages or expressing feelings but merely for establishing and sustaining human contact.
The act of speaking serves primarily the end of sociability. It does not have to mean anything, but it has to be continuous. At dinner parties a prolonged silence is the most embarrassing thing in the world: it seems to indicate that sociability has failed. It is often broken by more than one person’s speaking at the same time -- excuse me -- sorry -- after you -- no, after you -- and what is said is far less important than the fact of somebody having said something, anything. Every body breathes a sigh of relief, especially the hostess.
We have no means of knowing what the language of, say Stone Age man, was like, but we know something of that ancient language known as Indo-European because its structure and some of its vocabulary, much changed, survive in the daughter languages, which means most of the languages of Europe. It seems to have been a complex language, with a rich grammar, not at all like Malay or Chinese, and it is fairly certain that the further back we go in our study of language the greater complexities we find.
The simplification of language is essentially a part of the modernization of language: modern English is grammatically much simpler than its ancestor Anglo-Saxon, and Italian and Spanish are much simpler than their mother Latin. It is wrong to think of the first talkers taking a few linguistic bricks, joining them together, then baking more bricks and adding them to make a more and more imposing structure. An original babble was associated with a particular feeling or thought, but it was only in the period after, say, the break-up of the Roman Empire that grammarians began to analyze the parts of this babble and come up with terms like noun, verb, adjective, and adverb.
All of us say things we never said before, and without much conscious effort; we' re always inventing new things to say. That is the great human talent. This talent is based, however, on a very simple peculiarity of the human brain -- its capacity to think in opposed structures.
Look at it this way: the spectrum has many colors in it, and man learned to pick out colors as separable items. He did more; he learned how to make them into signs of opposed meaning. You have only to think of a traffic signal to see that this is so. Now out of the babble of noise which the human vocal system is capable of producing it is possible to separate specific sounds and oppose one to the other. Pick does not mean the same as pig, because/k/is opposed to/ g/, though those two sounds only differ (in English, anyway) in that one is breathed and the other sung. This structuralist gift of the human brain enables us to talk of tiny structures that oppose each other in doing separate jobs and, taken together, add up to a language.
What makes human beings different from the rest of the animal world is their ability to ______.

If an American lady says "Don't call me Mrs. Smith, just call me Sally", that shows ______.
Rodney Mace, 35, is married with two young children, and is a part-time teacher of architectural history. "I am constantly surprised by other people’s surprise, when they come to the house and see me cleaning a floor or hanging out the washing. Their eyes open wide at the sight of it ! Much of the comment comes from men, but I am even more surprised at the number of women who comment too."
His wife Jane, an Oxford graduate in modem languages, has a demanding full-time job. She is director of the Cam bridge House literacy scheme for adults in South London. Her working week involves several evenings and Saturdays, and at these times her husband is in sole charge of home and family. Apart from this, they share household jobs and employ a child-minder for the afternoons. This enables him to teach two days a week and to do what he considers is his principal work: writing. He has written several books and spends much of his time in the British Museum Reading Room, cycling there from his home in Brixton.
People ask the Maces if they think that their children miss them. One can argue that satisfied parents generally have satisfied children, but in any case the Maces are careful to reserve time and energy to play with their children. "And they have now developed relationships with other adults and children."
Previously, Rodney Mace worked fun-time and Jane only part-time. Then 18 months ago, the director of the literacy scheme left. "It seemed to me that Jane was very well suited to do this job. She was very doubtful about it. But I urged her to apply. She did, and she got it. "Jane Mace confirms that she needed this encouragement, as so many women initially do.
Did his male ego suffer from the changeover？ Nothing like that occurred. But he still seems amazed at the way it changed his thinking. "I felt that we were finally going to be partners. I felt enormous relief. I wash’t avoiding responsibility, but changing it. Our relationship is so much better now. It has bee3a a change for the good for both of us -- I think for all of us, in every aspect of our lives. I cannot overemphasize that in every aspect. I think it is fundamental that the woman works. The idea of equal partnership is an illusion if one partner doesn’t work."
The article is about a couple whose married life is happier because ______.
