Language learning begins with listening. Children are greatly different in the amount of listening they do
before they start speaking, and later starters are often long listeners. Most children will "obey" spoken
instructions some time before they can speak, though the word "obey" is hardly accurate as a description
of the eager and delighted cooperation usually shown by the child. Before they can speak, many children
will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from the noises babies make to their first spoken words leads
to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months
one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But
since these can't be said to show the baby's intention to communicate, they can hardly be regarded as
early forms of language. It is agreed, too, that from about three months they play with sounds for
enjoyment, and that by six months they are able to add new words to their store. This self-imitation
(模仿) leads on to deliberate (有意的) imitation of sounds made or words spoken to them by other
people. The problem then arises as to the point at which one can say that these imitations can be
considered as speech.
It is a problem we need to get out teeth into. The meaning of a word depends on what a particular
person means by it in a parti cular situation and it is clear that what a child means by a word will change
as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for
his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for
his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say
continues after the child has begun to speak for himself, I doubt, however whether anything is gained
when parents take advantage of this ability in an attempt to teach new sounds.
