请帮忙分析2个定语从句的句子
1.Life is like a long race where compete with others to go beyond ourselves.
这道题的答案分析里分析的是： race是先行词,在定语从句中做状语
2.Today,we’ll discuss a number of cases where beginners of English fail to use the language properly.
答案解析：cases是先行词,它在定语从句中做状语,所以应该选择关系副词where,表示“在……情况下”
答案解析太简单了,我看不懂,请帮我分析一下谢谢
这两道题所填的关系词都是where
