Which 在從句中承擔(dān)主語,謂語,當(dāng)句子成分缺少時(shí)用which
where在從句中做地點(diǎn)狀語,既句子成分完整,主謂都不缺
in which=where或when 可以替換 是將介詞提前的一種用法能說的再詳細(xì)一點(diǎn)嗎定于從句的三要素就是：先行詞，關(guān)系詞以及關(guān)系詞在從句中做的成分。which和where之間的區(qū)別就在于他們?cè)趶木渲兴嫉某煞莶煌Ｖ骶?先行詞+where +從句主語+從句謂語+從句賓語作地點(diǎn)狀語主句+先行詞+which+從句謂語+從句賓語 或者 主句+先行詞+which+從句主語+從句謂語作從句的主語或謂語所以在分析如何使用時(shí)，首先看從句是否缺少成分就可以了，不要從字面意思看There is a park which was on fire last night.There is a park where I alwaysplay with my friend 或者There is a park in which I always play with my friend.
