Firms that use computers have found that the number of staff _____ is needed for quality control can be greatly reduced.
A．whoseB．a(chǎn)sC．whatD．that
D

試題分析：通過分析句子結(jié)構(gòu)，可知這個句子中包含一個定語從句。that在定語從句中作主語，故用that。
點評： 限定性定語從句，that即可代表事物也可代表人，which代表事物；它們在從句中作主語或賓語，that在從句中作賓語時�？墒÷躁P系詞，which在從句中作賓語則不能省略。而且，如果which在從句中作“不及物動詞＋介詞”的介詞的賓語，注意介詞不要丟掉，而且介詞總是放在關系代詞which的前邊，但有的則放在它原來的位置
