问题    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【C1】______, they were like newborn children, unable to use this【C2】______tool. Yet once language developed, the possibilities for mankind’s future【C3】______and cultural growth increased.
   Many linguists believe that evolution is【C4】______for our ability to produce and use language. They【C5】______that our highly evolved brain provides us【C6】______an innate language ability not found in lower【C7】______. Proponents of this innateness theory say that our【C8】______for language is inborn, but that language itself develops gradually,【C9】______a function of the growth of the brain during childhood. Therefore there are critical【C10】______times for language development.
   Current【C11】______of innateness theory are mixed; however, evidence supporting the existence of some innate abilities is undeniable.【C12】______, more and more schools are discovering that foreign languages are best taught in【C13】______grades. Young children often can learn several languages by being【C14】______to them, while adults have a much harder time learning another language once the【C15】______of their first language have become firmly fixed.
【C16】______some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been【C17】______from other human beings do not possess language. This demonstrates that【C18】______with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language【C19】______than any innate capacities. These theorists view language as imitative, learned behavior.【C20】______, 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.
【C20】
选项 A、As a result
B、After all
C、In other words
D、Above all
答案C
解析 本题考查副词。本句功能是以另一种方式解释前文中的imitative，learned behavior (模仿性的后天行为)。In other words“换言之，换句话说”；As a result“结果是”；After all“毕竟”；Above all“首先”。所以答案为C。
