问题      From childhood to old age, we all use language as a means of broadening our knowledge 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 human kinds’ future 【C3】______ and culture 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】______ innate language ability not found in lower 【C7】______ . Proponents of this innate- ness 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 been 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 developments. Some linguists believe that this is even more basic to human language 【C19】______ than any innate capacities. These theories 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.
【C18】
选项 A、interaction
B、contrast
C、comparison
D、exposition
答案A
解析 名词词义题。句意为：这显示出与其他人的互动交往对语言的正确发展是必要的。interaction“交互作用”；contrast和comparison都表示“对比”，前者更强调差异，而后者强调相似；exposition“暴露，说明”，常与介词to搭配。因此A ，符合文意。
