12.(2013•湖南，21)Happiness and success often come to those________are good at recognizing their own strengths.

答案　who　[句意：幸福和成功经常青睐那些善于意识到自己长处的人。先行词为those，将先行词代入定语从句后为：Those are good at recognizing their own strengths.由此可见，先行词在定语从句中作主语，且表示“人”，故用who。]

13.(2013•四川，9)Nowadays people are more concerned about the environment________they live.

答案　where　[句意：现在人们更加关心他们居住的环境。先行词是environment，将先行词代入定语从句后为：They live in the environment.由此可见关系词在定语从句中作地点状语，故用where引导。]

14.(2013•江西，33)He wrote a letter ________ he explained what had happened in the accident.

答案　where　[句意：他写了一封信，信中他解释了事故中发生了什么。将先行词letter代入从句为：He explained what had happened in the accident in the letter.由此可知从句中缺少状语，应该用关系副词where，相当于in which。]

15.(2012•全国Ⅱ，8)That evening，________I will tell you more about later，I ended up working very late.

答案　which　[句意：稍后我会告诉你更多关于那晚的事，那晚我工作到很晚。先行词为That evening，将先行词代入定语从句后为：I will tell you more about that evening later.由此可见先行词在定语从句中作about的宾语，且表示“物”，故用which引导。本题易误填when，考生只看到先行词为表示时间的名词，但没有注意先行词在定语从句中的功能。]

Ⅱ.语篇填空

在设空处填入一个适当的关系代词或关系副词，使文章结构完整，语意通顺。
