whyhedidn’tturntohisfriendsforhelpyesterday.關(guān)系副詞的用法并非先行詞是表示時間、地點、原因的詞時，都選用關(guān)系副詞when,where,why,而是要先判斷先行詞在從句中是做狀語還是主語賓語。定語從句的關(guān)系副詞Thisisthefactory

Ivisitedlastyear.visit是及物動詞，需要接賓語，thefactory放在從句中做visit的賓語，故選擇指代物的關(guān)系代詞which/that，且可以省略。Thisisthefactory

Iusedtowork.work是不及物動詞，不需要接賓語，thefactory放在從句中做地點狀語，故選擇指代地點狀語的關(guān)系副詞where或inwhich。(which/that)where/inwhich“介詞+關(guān)系代詞”引導(dǎo)的定語從句1.when相當于“at/in/on/during等+which”Iremembertheday________________
