that 還是 when

在通常情況下，表示時間的名詞后應用關系副詞 when 來引導定語從句。但下面一句是例外，你能看出它的特殊性嗎？

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：

She says that she’ll never forget the time ________ she works as a secretary in our company.

A. which                        B. when                            C. how                        D. where

請再做一組試題(答案均選A)：

(1) Our company will move to a tall building _______ we bought last month.

A. which                        B. when                            C. how                        D. where

選A，which 在定語從句中用作動詞 bought 的賓語。

(2) Our company will move to a tall building _______ has just been complete.

A. which                        B. when                            C. how                        D. where

選A，which 在定語從句中用作主語。

(3) Our company will move to a tall building _______ we worked two years ago.

A. where                        B. when                            C. that                        D. which

選A，where 在定語從句中用作狀語。
