方法一: 用關系代詞,還是關系副詞完全取決于從句中的謂語動詞。及物動詞后面無賓語,就必須要求用關系代詞。例如:
 ?。ㄥe) This is the mountain village where I visited last year.
  (錯) I will never forget the days when I spent in the countryside.
 ?。▽Γ?This is the mountain village (which) I visited last year.
  (對) I'll never forget the days (which) I spent in the countryside.
  習慣上總把表地點或時間的名詞與關系副詞 where, when聯(lián)系在一起。此兩題錯在關系詞的誤用上。
方法二: 準確判斷先行詞在定語從句中的成分(主、謂、賓、定、狀),也能正確選擇出關系代詞/關系 副詞.先行詞在從句中作主、定、賓語時,應選擇關系代詞;先行詞在從句中作狀語時,應選 擇關系副詞。例如:
? ? ? (對)Is this the museum which you visited a few days ago?
? ? ? (對)Is this the museum where the exhibition was held?
