A．for which

B．which

C．where

D．of which

Answer 1

C

試題分析：考查從句，從句people suddenly have trouble recognizing family members, friends or even themselves句子不缺少成份，所以選where，句子意思“有些人不善于回憶名字和臉，這有可能是連忙正，那里的人們突然在認識家人、朋友和自己有困難”，所以選C
點評：做從句題時，首先看從句是否缺少成份，如果缺少成份就選擇關系代詞，關系代詞不僅起引導作用而且做成份；如果不缺少成份，就選擇關系副詞，關系副詞不做成份，只起引導作用。
