when
和
what
time
的区别是它们的词性和句子功能。
when
和
what
time
在词义上并无太大差别,都表达“什么时间”,也都可以用来作疑问词引导疑问句,对时间提问。但是,在用作疑问词提问和从句引导词时,它们不仅在词性上有区别,而且句子功能也不一样。when
可作副词、连词、代词和名词,用于疑问句或从句中通常做副词,称作“关系副词”。what
time
则是名词性词组(形容词+名词),用作疑问词时,所问对象通常是含具体的时间的名词性句子成分,如表语和介词宾语。在引导从句方面,when
可引导状语从句(副词性)、定语从句(形容词性)和宾语从句(名词性);what
time
则仅用于引导宾语从句。比较例句:
疑问句
when/what
time
will
the
meeting
begin?
when/what
time
was
the
meeting?
when/what
time
did
the
meeting
begin?
从句
i
don't
know
when/what
time
the
meeting
is
going
to
start.
(宾语从句。可换用)
i
saw
him
in
the
house
when
i
came
home.
(状语从句。不能用
what
time)
we
remember
the
days
when
he
visited
our
hometown
10
years
ago.
(定语从句。不能用
what
time)
he
is
not
sure
about
what
time
the
train
will
arrive.
(介词宾语从句。不能用
when)
