When a human infant is born into any community in any part of the world it has two things in common with any infant（1）, provided neither of them have been （2）damaged in any way either before or during birth. Firstly, and most obviously, new born children are completely helpless. Apart from a powerful capacity to pay attention to（3） their helplessness by using sound, there is nothing 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 （4）within minutes of birth and run with herd within a few hours. Although young animals are certainly in risk （5）,sometimes for weeks or even months after birth, compared with the human infant they very quickly grow 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 （7）that it reveals the second feature which it shares with all other undamaged human infants, a capacity to learn language. For this reason, biologists now suggest that language be（8） "species specific" to the human race, that is to say, they consider the human infant to be genetic programmed（9） in such way that it can acquire language.（10） This suggestion implies that just as human beings are designed to see three-dimentionally and in colour, 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 developments as well-formed human beings.
