Question

A good friend of mine from ___ I was born showed up at my home right before I left for Beijing.

A good friend of mine from ___ I was born showed up at my home right before I left for Beijing.
A how B whom C when D which

分析句子结构
这地方用where 也可以吧？各位？

Answer 1

用WHERE可以。但是句意就变成了，从我家乡来的朋友了（来自我出生的地方的朋友）
选C。一个从我出生起就和我结识的朋友，在我出发去北京前出现在我家里。
A good friend of mine 我的一个朋友。是主语
from _when__ I was born 定语从句，修饰a friend。所以翻译成，从我出生起就结交的朋友。
showed up出现。这句话的谓语。

at my home。这句话的地点状语
right before I left for Beijing就在我出发去北京之前。这句话的时间状语

Answer 2

应该是填where.但是不叫定语从句，而是宾语从句吧。a
good
friend
of
mine
from
=
a
good
friend
of
mine（who
comes）from,介词后面加宾语，who是主语
comes
from是谓语动词。谓语动词后面一般紧跟着宾语。故此处应该是宾语从句才对吧。
the
place
where
i
was
born=the
place
on
which
i
was
born
才是定语从句，而且此处的on不是想要就要不要就不要的，一定要记得加上啊。而where
i
was
born是表示地点的。例如：put
the
book
where
it
was.把书放在它原来的地方。where
it
was这里的where
it
was
是地点状语。

Answer 3

选C；
A good friend （of mine from when I was born） showed up（ at my home ）（right before I left for Beijing）.
主干A good friend showed up；
括号一修饰friend；
括号二方位状语；
括号三时间状语

Answer 4

C
A good friend of mine 是主语 showed up 是谓语
from when I was born 是一时间状语 从我出生的时候

Answer 5

CA good friend of mine
from when I was born是借词短语修饰friend，整个句子的骨干是A friend showed up
