Question

4．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．
51．What does the writer think of the change and development of language？
He thinks it is not a bad thing/not bad/a good thing/good
52．Why do people use different sets of words and expressions according to the passage？

53．How many reasons for language change are mentioned in this passage？
The writer mentionstwo/2 reasons
54．How do young people help develop language？
They do it when theycommunicate/talk with others of their own age
55．What is considered a dead language according to the passage？
The language thatdoesn't change/never changes/keeps the same over time is considered a dead language．．

Answer 1

分析 本文叙述了语言总是在发展变化的，这不是一件坏事．语言变化的原因是说话者本身变化的需要，以及不同的人有不同的语言经历．语言变化的方式是：一方面是许多语言变化是从年轻人开始的；另一方面是我们用许多不同的方法获得新词．语言不随着时间而变化，会被认为是死语言．

解答 51．He thinks it is not a bad thing/not bad/a good thing/good．细节理解题．根据Language is always changing and developing．This isn't a bad thing可知语言是不断变化和发展的，这不是一件坏事，故答案为：He thinks it is not a bad thing/not bad/a good thing/good．
52．Because their ages，jobs，education levels and so on are different．细节理解题．根据People use different sets of words and expressions，because they have different ages，jobs，education levels（水平） and so on．可知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，故答案为：Because their ages，jobs，education levels and so on are different．
53．The writer mentions two/2 reasons．细节理解题．根据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可知本文提到了语言变化的两个原因，故答案为：The writer mentions two/2 reasons．
54．They do it when they communicate/talk with others of their own age．细节理解题．根据"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．"可知年轻人和同龄人交流时，他们的语言在语法、词汇和短语不同于年长的人，故答案为：They do it when they communicate/talk with others of their own age．
