Ⅰ.单句语法填空
1．In our factory there are 2,000 workers, two thirds of ________ are women.
whom [two thirds of whom即two thirds of the 2,000 workers。关系词在从句中作介词of的宾语，因此用宾格whom。]
2．A football fan is a person ________ has a strong interest in football.
who/that [句意：足球迷是对足球有强烈兴趣的人。分析句子成分可知，此处引导定语从句，从句中缺少主语，应用关系代词，指人可用who/that。]
3．Is there anyone in your class _____ family is in the country?
whose [此处引导定语从句，先行词为anyone。whose引导定语从句，在从句中作主语family的定语。]
4．I shall never forget those years ________ I lived on the farm with the farmers.
when [句意：我永远也不会忘记和农民们一起住在农场的那些年。years是表示时间的名词，且从句中不缺少主语和宾语，故用when引导定语从句，when在从句中作时间状语。]
5．We all know that this is the second book ________ he has ever written.
that [句意：我们都知道这是他写过的第二本书。当先行词前有序数词修饰时，要用that引导定语从句。]
6．________ is often the case in India, foreign firms will face big barriers.
As [此处为as引导的非限制性定语从句，as在从句中作主语，指代逗号后面整个主句的内容。]
7．It is such a good book ________ I want to buy immediately.
as [根据句子结构可知，本句含有一个限制性定语从句。先行词为a good book，并且从句中缺少宾语，又由于先行词被such修饰，故关系代词只能用as。]
8．Our life has reached the stage ________ we should decide what to do and how to do it by ourselves.
where [句意：我们的人生已经走到了应该独立决定该做什么和如何去做的阶段了。分析句子结构可知，本句中含有一个定语从句。先行词the stage作为抽象地点，并且从句中缺少地点状语，因此应用关系副词where。]
