在英语中,定语从句是一种常见的从句结构,用于修饰名词或代词,使句子信息更为详尽。在这些从句中,关系代词(如"who"、"which"、"whom"等)起着连接主句和从句的作用,并且它们的选择和用法受先行词的影响。关系代词的正确使用不仅能够提高语句的清晰度,还能帮助表达更加准确的语义。
<例句>
I still remembei the day when she was killed.
我仍记得她被害的那一天。
<语法分析>
在由when,where,why和how等词引导的定语从句时,它们分别指前面先行词所表示的时间、地点、原因和
方式,否则引导的就不是定语从句。定语从句主语和谓语的一致性决定于先行词的数,关系代词如指前面
的整个句子时,谓语动词用单数。定语从句可转化为分词短语,如果因为时态的限制或含有情态动词的时
候,则不可以转换。
