题目内容
4．Those are my twin sisters．_______ of them are interested in soap operas．（ ）| A． | Each | B． | All | C． | Both | D． | One |
分析 句意：那些是我的双胞胎姐妹们．她们两个都对肥皂剧感兴趣．
解答 答案：C．Both 由"那些是我的双胞胎姐妹们"看出后面句子中的them指的是两个人，both of（…中的两个都）用于两者间，其后谓语动词用复数，其他选项的意思和用法分别为：each of（…中的每一个），其后谓语动词用单数，all of（…中的全都）用于三者或三者以上，其后谓语动词用复数，one（一个），其后谓语动词用单数，故答案选C．Both
点评 判断清楚句中人称代词所指对象，区分清楚不定代词的意义，注意与其搭配的谓语动词的单复数形式．
