完形填空。
Is language, like food, a basic human need without which a child at a critical period of life can
be
1 and damaged? Judging from an experiment in the thirteenth century, it may be. Hoping to
discover what language a child would speak if a baby heard no mother
2 , the experimenter
told the nurses to keep silent.
All the
3 died before the first year. But clearly there was more than lack of language here.
What was missing was good mothering. Without good mothering, in the first year of life
4 , the
capacity to survive is seriously affected.
Today no such severe lack exists as that ordered by the experimenter.
5 , some children are
still backward in speaking. Most often the reason for this is that the mother is
6 to the signals of
the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected,
the ideal time for
7 skills passes and they might never be learned so easily again. A bird learns to
sing and to fly rapidly at right time, but the process is slow and hard once the
8 stage has passed.
Experts suggest that speech stages are reached in a fixed sequence and at a
9 age, but there are
cases where speech has started
10 in a child who eventually turns out to be of high IQ. At twelve
weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words
and understand simple
11 ; at eighteen months he has a vocabulary of three to fifty words. At three
he knows about 1,000 words which he can put into sentences, and at four his language differs from
that of his parents in style
12 grammar.
Recent evidence suggests that an infant is born with the
13 to speak. What is special about
man's brain, compared with that of the monkey, is the complex system which enables a child to
14
the sight and feel of, say, a toy-bear with the sound pattern "toy - bear". And even more
15 is the
young brain's ability to pick out an order in language from the mixture of sound around him, to analyse,
to combine and recombine the parts of a language in new ways.
