回答1:

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)
When面比较大,问上午,下午,明天,昨天,上周甚至明年,去年。
What time 具体,问几点钟?
如:
When will you graduate? 你什么时侯毕业?
I will graduate next year. 我明年毕业。
What time will you do morning exercises?
你们几点钟做早操?
---We will do morning exercises at nine o'clock?

what time和when的区别

回答3:

what time与 when 都可以表示“什么时候”.
前者所表示的时间比较精确,指“几点钟”,“几时几分”;
后者所表示的时间范围广,有时也可指“几点钟”,“几点几分”,用来代替what time.
例如:
"What time(When) does your mother go to work?" “你母亲什么时候去上班?”
"She goes to work atseven" “她七点去上班.”
"When will he come back?".“他什么时候回来?”“
"He'll come back tomorrow ”他明天回来.”
此外,what time还可以用作名词,作主语或介词宾语.
简单的说:
when和what time的区别在于what time问具体的时间,如某一天的几点钟,甚至几分钟,而when问的时间比较笼统.因此在问生日日期时,不要用“what time”这个特殊疑问词而应该用when.
