答案是E 我的问题是：答案解释说D中的非限定性定语从句改变了原句含义。不大明白啊。。。印象中还有几个题也说非限定性定语从句改变文意。记得prep笔记上说非限定和限定的区别就是是否有延伸性。可我总觉得从含有上讲，二者区别不大。。。 这个问题怎么解决？怎么才能更有效地区分和决定何时用限定性定语从句或非限定性定语从句作者: 草木染湘 时间: 2011-9-8 16:21
twenty-one是来修饰ceramic dog figurines 的嘛，原意是说，ceramic dog figurines 总共有21个， 如果用了非限制性定语人句就改变了原意了，就是说，其中有21个ceramic dog figurines 怎么怎么样，总共的ceramic dog figurines可能还有很多个。外延就改变了。作者: ssxxtt27 时间: 2011-9-10 20:58
