{{B}}
Text{{/B}} 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 {{U}}(26) {{/U}}, they were like newborn children, unable
to use this {{U}}(27) {{/U}} tool. Yet once language developed,
the possibilities for human kinds future {{U}}(28) {{/U}} and cultural
growth increased. Many linguists believe that evolution is
{{U}}(29) {{/U}} for our ability to produce and use language. They
{{U}}(30) {{/U}} that our highly evolved brain provides us {{U}}(31)
{{/U}} an innate language ability not found in lower {{U}}(32)
{{/U}}. Proponents of this innateness theory say that our {{U}}(33)
{{/U}} for language is inborn, but that language itself develops gradually,
{{U}}(34) {{/U}} a function of the growth of the brain during childhood.
Therefore there are critical {{U}}(35) {{/U}}times for language
development. Current {{U}}(36) {{/U}}of innateness
theory are mixed, however, evidence supporting the existence of some innate
abilities is undeniable. {{U}}(37) {{/U}}, more and more schools are
discovering that foreign languages are best taught in {{U}}(38) {{/U}}
grades. Young children often can learn several languages by being {{U}}(39)
{{/U}} to them, while adults have a much harder time learning another
language once the {{U}}(40) {{/U}} of their first language have become
firmly fixed. {{U}} (41) {{/U}} some aspects of language
are undeniably innate, language does not develop automatically in a vacuum.
Children who have been {{U}}(42) {{/U}} from other human beings do not
possess language. This demonstrates that {{U}}(43) {{/U}} with other
human beings is necessary for proper language development. Some linguists
believe that this is even more basic to human language {{U}}(44) {{/U}}
than any innate capacities. These theorists view language as imitative, learned
behavior. {{U}}(45) {{/U}}, 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.
【答案解析】[精解] 根据分析,本句中的“this”和“even more basic”分别指代上句的“interaction with other human beings”和“necessary”,此处所填词对应上文中的language development。也就是说, language acquisition语言习得。appreciation欣赏,感激; requirement要求;alternative转移,转变,转换。
【正确答案】
C
【答案解析】[精解] 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。
