Ⅱ.能力培养和提升

一、用适当的关系词填空

【练习1】(2012·广东名校联考优化卷十四)Nearly everything they study at school has some practical use in their life，but is that the only reason 19.____________they go to school?

解析：在reason后引导定语从句，用why表示原因。

答案：why

【练习2】(2012·广东命题专家原创卷一)When facing hardships，only those 25. ____________ are confident will achieve success.

解析：关系代词引导定语从句，修饰前面的those。

答案：who

【练习3】(2012·高考大纲全国卷Ⅱ)That evening，____________I will tell you more about later，I ended up working very late.

解析：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。考查定语从句。

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。

答案：which

【练习4】(2012·高考天津卷)I wish to thank Professor Smith，without ____________help I would never have got this far.

解析：句意：我想要感谢史密斯教授，没有他的帮助，我绝不会有这样的成就。考查定语从句关系代词的选用。根据句意及句子结构可知，空格处为定语从句的引导词，先行词为Professor Smith，将先行词代入定语从句后为：Without Professor Smith’s help I would never have got this far，由此可见先行词在定语从句中作help的定语，故答案为whose。

答案：whose

【练习5】(2012·高考江苏卷)After the flooding，people were suffering in that area，____________urgently needed clean water，medicine and shelter to survive.

解析：句意：洪灾过后，那个地区的人们正在受苦，为了生存，他们急需干净的水、药品和住所。考查非限制性定语从句。将先行词people代入定语从句后为：people urgently needed clean water，medicine and shelter to survive，可知先行词在从句中作主语，所以用who。

答案：who

【练习6】(2012·高考浙江卷)We live in an age ____________more information is available with greater ease than ever before.

解析：句意：我们生活在一个更多的信息比以前任何时候都更容易获得的时代。考查定语从句。先行词是age。因为关系词在定语从句中作时间状语，故用when引导。

答案：when

【练习7】(2012·高考四川卷)In our class there are 46 students，of____________half wear glasses.

解析：句意：我们班有46名学生，其中有一半戴眼镜。考查定语从句。前后两部分之间没有连词，故空格处引导定语从句。先行词为46 students，将先行词代入定语从句后为：Half of the 46 students wear glasses.由此可见先行词在定语从句中作of的宾语，且表示“人”，故用whom引导。

答案：whom

【练习8】(2012·高考重庆卷)Sales director is a position ____________communication ability is just as important as sales skills.

解析：句意：销售总监是一个职位，在这个职位中，交际能力和销售技巧同等重要。考查定语从句。先行词为position，代入定语从句后为：Communication ability is just as important as sales skills in the position.由此可见先行词与介词in一起作状语，position在本句中表示“模糊化的地点”，故用where。

答案：where
