题目内容
12．He is father．（ ）| A． | Jim's and Lucy's | B． | Jim and Lucy's | ||
| C． | Jim's and Lucy |
分析 他是Jim和Lucy的爸爸．
解答 答案B．
本题考查名词所有格．在英语中，特别是表示有生命的名词，可以加's表示所属关系，名词的这种形式我们称之为名词的所有格． 如果一个东西为两个人或者两个以上的人共同拥有，只在最后一个名词后面加's．本题中，主语为He，由此可见，他既是Jim的爸爸，也是Lucy的爸爸，即两人的爸爸是一个人，是共有的，所以必须在后一个名词后加's，A表示两者各自所有，不符合题意，C形式错误．只有B表示共有．故选B．
点评 本题中，主语的单复数对于所有格来说很重要，要看清主语，决定所有格的形式．
