10、系代词who,whom,whose,which,that等来引导定语从句；如果从句缺少状语时，就得选用关系副词when,where,why等来引导包含定语从句的主从复合句。切记：务必根据先行词在定语从句中所从当的成分及从句的句子结构或功能来选择相应的关系代词或关系副词。试比较：推荐精选1）I still remember the days which we spent in london.（注：先行词days在从句中充当spent的宾语。）2）I still remember the days when we studied in london.(注：先行词days 在从句中充当时间状语。)3
