一道極易出錯的陷阱題

請看下面一題，是考查非限制性定語從句，還是考查……？

He had a lot of friends, only a few of ______ invited to his wedding.

A. whom                        B. them

C. which                        D. who

【分析】容易誤選 A，認為這是非限制性定語從句。最佳答案是B，這不是非限制性定語從句，而是一個獨立主格結構，因為空格后的動詞 invited 并不是一個完整的謂語，而是一個過去分詞。當然，假若在 invited 前加上助動詞 were，則是一個非限制性定語從句，答案便應選A。比較：

(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

答案選B，none of them carried out in their work 是獨立主格結構，其中的 carried out 為過去分詞。

(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

答案選A，none of which were carried out in their work 是非限制性定語從句，注意與上例比較句中多了一個助動詞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

答案選B，由于兩句之間增加了一個并列連詞but，使得該句成了一個并列句。
