一、關(guān)于時間定語從句和時間狀語從句的區(qū)別
關(guān)鍵是看前面有沒有先行詞,有就是定語從句,沒有就是時間狀語從句.舉例如下：
1.By the time when you arrived in Beijing,we had stayed there for two weeks.
有先行詞 the time 那么when you arrived in London就是定語從句　
2.when you arrived inBeijing,we had stayed there for two weeks.
沒有先行詞 when you arrived in London就是時間狀語從句
二、關(guān)于地點(diǎn)定語從句和地點(diǎn)狀語從句的區(qū)別
where引導(dǎo)的狀語從句是充當(dāng)主句的地點(diǎn)狀語而已,where前面沒有先行詞.where引導(dǎo)的定語從句它是修飾先行詞(表地點(diǎn)的名詞/名詞短語)的.舉例如下：
1.You'd better make a mark where you have any questions.
2.You`d better make a mark at the place where you have any questions.
以上兩句字意思相同,但第一個是狀語從句,后一個是定語從句.定語從句有先行詞THE PLACE,而狀語從句沒有.狀語從句中where引導(dǎo)的句子做地點(diǎn)狀語,不出現(xiàn)place.定語從句出現(xiàn)先行詞place,再用where引導(dǎo)的定語來修飾place.
如果還有什么疑問,可以繼續(xù)提問我,我很樂意為您解惑.
