Question

20．Language is always changing and developing．This isn't a bad thing．If English hadn't changed for a long time，we won't have words to describe telephones，washing machines，computers or some other new things．
  Language changes for several reasons．First，it changes because the needs of its speaker change．New technologies，new products，and new experiences need new words to express them clearly．Another reason for change is that different people have different language experiences．People use different sets of words and expressions，because they have different ages，jobs，education levels（水平） and so on．
  How does language develop then？On the one hand，many of the languages changes begin with young people．When young people communicate with others of their own age，their language grows in grammar，words and expressions that are different from the older people's．Some have a short lifetime but others can influence the language for long．On the other hand，we get new words in many different ways．We borrow them from other languages，we create them by making words shorter or combining words and we make them out of proper names．
  Languages that don't change over time are considered dead languages．The fact that English changes so much shows that it is alive and well．

Answer 1

分析 语言是不断变化和发展的，这不是一件坏事，如果英语没有长时间进行改变，我们将没有语言来描述电话、洗衣机、电脑或者其他一些新东西．
语言变化有几个原因．首先，他改变是因为说话人改变的需要．新技术、新产品、新体验需要新的词汇来表达，变化的另一个原因是，不同的人有不同的语言经验．人们使用不同的词汇和表达方式，因为他们有不同的年龄、工作、教育程度等．语言是如何发展的呢？一方面，许多语言的变化开始于年轻人．当年轻人与其他人交流时，他们的语言在语法、词汇和表达方式上都与老年人不同．有些人有短暂的一生但其他人会长久影响语言．另一方面，我们在许多不同的方式中得到新的词汇．我们借用其他语言，我们通过把单词缩短或组合单词，然后把它们从适当的名字中创造出来．
不随时间而变化的语言被认为是死亡的语言，英语变化如此之多，这一事实表明他很活跃，而且很好．
