5．Stop watching TV，             mother will be angry with you when she comes home．（　　）
A．ifB．butC．orD．and

分析 别看电视了，不然当你妈妈回家时她会生你的气．

解答 答案：C【解析】考查连词．观察句子并联系语境可知本句型为祈使句+or+陈述句"，表示在以祈使句（Stop watching TV）为条件下的相反假设，意为"否则，要不然"，（不然妈妈会对你生气）这样前后语义才能连贯．可以把这类句型中的祈使句换为一个条件句更好理解．如本句可以转化成If you don't stop watching TV，mother will be angry with you when she comes home．所以根据上下句的关系并联系用法可知这里用or表示"否则"．故选C．

点评 此题重点考查并列连词or的特殊用法．注意or一词多义的情况．联系前后语境并结合固定用法判断出应使用的正确的连词，注意前后语义的连贯并符合逻辑关系．or为常考的连词，记住它的特殊用法做题就会很轻松了．

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．
