19．Many people believe that you lose the ability to learn new languages as you get older．Language experts，however，will tell you that you're never too old to learn a new language．As you get older，it can be more difficult to learn a new language，though．
Children and adults learn new languages in different ways．For children，language is their life．They study for thousands of hours every year，because they need to learn languages to become part of their communities．Adults，on the other hand，are already part of a language community．Learning a new language means becoming part of another language community，and adults rarely get the chance to practice as much as young children do．
Moreover，children learning a new language are expected to make mistakes．This gives them freedom when learning to be daring and confident．Adults，however，often feel pressured to be perfect when learning a new language．This can discourage many people and make it even harder to learn a new language．
When young children learn a new language，they come to see various languages as a"normal"part of society．This mindset （思维模式） helps them embrace learning a new language without feeling like they're doing something unusual or"too hard"．
So if you want to learn a new language，go for it!It's never too late to learn a new language．If you're older，it may take more work，but it can be done．If you're a young child，though，now is the time to step out and learn a new language!

分析 本文是一篇议论文．本文通过对比老人和孩子学语言的不同告诉大家既然什么时候学习一门新的语言都不晚，那么老人和孩子都可以学习新的语言．
解答 28．C．推理判断题．由题干中language is their life 定位到文中的"They study for thousands of hours every year…"．他们每年要花费成千上万个小时学习语言，故可以推知其意思是指孩子们进行大量的语言练习．故选C．
29．A．细节理解题．由题干中的make it hard for the old people to learn a new language定位到第三段最后一句"This can intimidate many people and make it even harder…"，this指代上句"Adults，however，often feel pressured to be perfect when learning a new language"．成人学习语言的时候，往往因为追求完美而感到有压力，也就是成人在学习语言时担心受到嘲笑．该段的首句是段落主题句，解题时要考虑到这个主题思想，就容易选出正确答案；故选A．
30．B．推理判断题．根据第二段Adults，on the other hand，are already part of a language community．Learning a new language means becoming part of another language community，and adults rarely get the chance to practice as much as young children do可知孩子和成年人之间学习态度不同，目的不同会导致学习结果的不同；故选B．
31．D．推理判断题．题干询问作者的观点，定位到文章的主旨段最后一段，由其中的"It's never too late to learn a new language"可知答案．既然什么时候学习一门新的语言都不晚，那么老人和孩子都可以学习新的语言．故选D．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
