From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us.When humans first 1 , they were like newborn children, unable to use this 2 tool.Yet once language developed, the possibilities for human kind?s future 3 and cultural growth increased.

　　Many linguists believe that evolution is 4 for our ability to produce and use language.They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood.Therefore there are critical 10 times for language development.

Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades.Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed.

16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum.Children who have been 17 from other human beings do not possess language.This demonstrates that 18 with other human beings isnecessary for proper language development.Some linguists believe that this is even more basic to human language 19 than any innate capacities.These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them.Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

   In bringing up children, every parent watches eagerly the child’s acquisition(学会)of each new skill ― the first spoken words, the first independent steps, or the beginning of reading and writing. It is common that parents hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, and a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm(热情) for life and his desire to find out new things for himself.

　　Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters; others are severe over time of coming home at night or punctuality(准时) for meals. In general, the controls imposed(强加的) represent the needs of the parents and the values of the community(社区) as much as the child’s own happiness.

　　As regards the development of moral standards （道德标准））in the growing child, consistency（连贯性） is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that “example is better than precept”. If they are not sincere and do not practise what they preach(说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled.

　　A sudden awareness of a marked difference between their parents’ principles and their morals can be a dangerous disappointment.
