题目内容
3．They are________（ ）| A． | man doctor | B． | man doctors | C． | men doctors |
分析 他们是男医生．
解答 答案：C
根据主语是they可知他们是医生，故doctor应用名词复数形式即doctors，结合选项可知man在句中作定语修饰doctors，根据man作定语修饰名词时，要随其后的名词的单复数变化而变化，故填men doctors，故选C
点评 本题考查可数名词的复数形式．在英语中可以用一个名词来修饰另一个名词，说明它的性质，用作形容词性的定语．这时，作定语的名词应为单数形式．但如果用man或woman修饰后面的复数名词，表示其性别，则前后两个名词都必须用复数形式
