2021屆高考英語第二輪定語從句備考復習教案
a. their b. whose c. which d. that
【陷阱】容易誤選b，認為這是非限制性定語從句。
【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構，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。
（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 為獨立主格結構。
（4） on sundays there were a lot of children playing in the park, _______ parents sat together joking.
a. their b. whose c. which d. that
選b. whose parents sat together joking 為非限制性定語從句，因為句中有完整的謂語 sat.
（5） on sundays there were a lot of children playing in the park, _______ parents were sitting together joking.
a. their b. whose c. which d. that
選b. whose parents were sitting together joking 為非限制性定語從句，因為句中有完整的謂語 were sitting.
9. if the man is only interested in your looks, _____ just shows how shallow he is.
a. as b. which c. what d. that
【陷阱】容易誤選a或b，誤這是非限制性定語從句。
【分析】正確答案為d，注意逗號前是一個條件狀語從句，逗號后是該狀語從句的主句，that 在此代表前文所述的情況，用作主句的主語。類似地，下面幾道題也選 that，而不選 which：
（1） if you promise to go with us, _____ will be ok.
a. as b. which c. and it d. that
（2） if you want a double room, _____ will cost another ￡15.
a. as b. which c. what d. that
（3） whether you go or not, _______ is quite all right with me.
a. that b. which c. and it d. so
（4） when i say two hours, _____ includes time for eating.
a. as b. which c. what d. that
10. she says that she'll never forget the time ________ she's spent working as a secretary in our company.
a. which b. when c. how d. where
【陷阱】容易誤選b，機械地認為時間名詞后必須用關系副詞when，地點名詞后用關系副詞 where.
【分析】正確答案為a.在時間名詞和地點名詞后是否用關系副詞要看它在定語從句中充當什么句子成分。一般說來，若用作主語或賓語，用關系代詞；若用作狀語，則用關系副詞。上面一題中的動詞 spent 缺賓語，故應用關系代詞 which或that.比較下面一題，由于空格后的句子不缺少主語或賓語，所以選關系副詞when：
