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。]
