[简答题]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 valuable tool. Yet once language developed, the possibilities for human kinds future 2 and cultural growth increased.
Many linguists believe that evolution is 3 for our ability to produce and use language. They claim that our highly evolved brain provides us 4 an innate language ability not found in lower organisms. Proponents of this innateness theory say that our 5 for language is inborn, but that language itself develops gradually, 6 a function of the growth of the brain during childhood. Therefore there are critical 7 times for language development.

These theorists view language as imitative, learned behavior. 15 , 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.
