高考臨近，以下是有關(guān)單項填空妙題精析(定語從句)，希望對大家有所幫助！

On Sundays there were a lot of children playing in the park, _______ parents seated together joking.

A. their B. whose

C. which D. that

【陷阱】容易誤選B，認(rèn)為這是非限制性定語從句(from www.nmet168.com)。

【分析】最佳答案是A。與上面一題相似，their parents seated together joking 不是非限制性定語從句，而是一個獨立主格結(jié)構(gòu)，因為空格后的動詞 seated 不是謂語，而是一個過去分詞，因為 seat 作動詞用時，是及物動詞。比較以下相似題：

(1) On Sundays there were a lot of children playing in the park, _______ parents were seated together joking.

A. their B. whose

C. which D. that

選B。whose parents were seated together joking 為非限制性定語從句，因為其后有完整的謂語 were seated。

(2) On Sundays there were a lot of children playing in the park, and _______ parents were seated together joking.

A. their B. whose

C. which D. that

選A。因為句中有并列連詞and，整個句子為并列句(from www.nmet168.com)。

(3) On Sundays there were a lot of children playing in the park, _______ parents sitting together joking.

A. their B. whose

C. which D. that

選A。their parents sitting together joking 為獨立主格結(jié)構(gòu)。

(4) On Sundays there were a lot of children playing in the park, _______ parents sat together joking.

A. their B. whose

(5) On Sundays there were a lot of children playing in the park, _______ parents were sitting together joking.

A. their B. whose
