was so upset.他没有告诉我他为什么那样心烦意乱。
注意： 关系代词与关系副词之间并非毫无关联， 两者之间存在密切的联系。在备考中尤其要注意以下几点：
1. 很多情况下关系副词用“介词＋which/whom”来代替， 其中的介词由先行词或定语从句中谓语动词的形式来决定， 例如：
The day when I met the famous pop star was the greatest day of my life.
= The day on which I met the famous pop star was the greatest day of my life.见到这位著名歌星的那天是我一生中最重要的日子。
I shall never forget those years when I lived with her.
= I shall never forget those years during which I lived with her.
我将永远不会忘记我跟她生活的那些岁月。
This is a hall where the medical conference will be held.
= This is a hall in which the medical conference will be held.
这是礼堂， 医学会议将在此召开。
2. 并非先行词表示时间或地点时都分别用when或where来引导相应的定语 |
