Question

He come last night when I was out.是定语从句吗？

Answer 1

是定语从句，先行词是last
night
He
came
when
I
was
out这个才是时间状语从句，找不到先行词
【【判断定语从句和时间状语从句从句的方法
定语从句与时间语状语从句的区别
当定语从句的引导词与时间状语的连接词都是when时，定语从句修饰、限制、说明时间名词，只能放在先行词的后面；而时间状语从句说明动作发生的情况，并且可以放在主句的前面。如：
Do
you
know
the
time
when
the
class
is
over?
你知道下课的时间吗？(定语从句)
It
was
already
five
o’clock
when
the
class
was
over.
—When
the
class
was
over,
it
was
already
five
o'clock.
当课结束时，已经是五点钟了。(时间状语从句)
】】】
就像这句
不能说成when
I
was
out，
he
came
last
night
.所以你说时间状语从句。
