高考英语典型易错陷阱题详解：一道极易出错的陷阱题

　　He had a lot of friends, only a few of ______ invited to his wedding.
　　A. whom　　　　　　　　　　　　B. them
　　C. which　　　　　　　　　　　　D. who
　　【分析】容易误选 A，认为这是非限制性定语从句。最佳答案是B，这不是非限制性定语从句，而是一个独立主格结构，因为空格后的动词 invited 并不是一个完整的谓语，而是一个过去分词。当然，假若在 invited 前加上助动词 were，则是一个非限制性定语从句，答案便应选A。比较：
　　(1) They put forward a lot of plans at the meeting, none of _______ carried out in their work.
　　A. which　　　　　　　　　　　　B. them
　　C. what　　　　　　　　　　　　　D. that
　　答案选B，none of them carried out in their work 是独立主格结构，其中的 carried out 为过去分词。
　　(2) They put forward a lot of plans at the meeting, none of _______ were carried out in their work.
　　A. which　　　　　　　　　　　　B. them
　　C. what　　　　　　　　　　　　　D. that
　　答案选A，none of which were carried out in their work 是非限制性定语从句，注意与上例比较句中多了一个助动词were。
　　(3) They put forward a lot of plans at the meeting, but none of _______ were carried out in their work.
　　A. which　　　　　　　　　　　　B. them
　　C. what　　　　　　　　　　　　　D. that
　　答案选B，由于两句之间增加了一个并列连词but，使得该句成了一个并列句。
