问题     When a human infant is born into any community in any part of the
world it has two things in common with any infant, provided neither of them (1)_____
have been damaged in any way either before or during birth. Firstly, and most (2)_____
obviously, new born children are completely helpless. Apart from a powerful
capacity to pay attention to their helplessness by using sound, there is nothing (3)_____
the new born child can do to ensure his own survival. Without care from some
other human being or beings, be it mother, grandmother, or human group, a
child is very unlikely to survive. This helplessness of human infants is in marked
contrast with the capacity of many new born animals to get on their feet within (4)_____
minutes of birth and run with the herd within a few hours. Although young
animals are certainly in risk, sometimes for weeks or even months after birth, (5)_____
compared with the human infant, they very quickly develop the capacity to
fend for them. (6)_____
    It is during this very long period in which the human infant is totally
dependent on the others that it reveals the second feature which it shares with all (7)_____
other undamaged human infants, a capacity to learn language. For this reason,
biologists now suggest that language be " species specific" to the human race, (8)_____
that is to say, they consider the human infant to be genetic programmed in (9)_____
such way that it can acquire language. This suggestion implies that just (10)_____
as human beings are designed to see three-dimensionally and in color and just
as they are designed to stand upright rather than to move on all fours, so they
are designed to learn and use language as part of their normal development as
well-formed human beings.
