where is the date from?
where did the date from?
问:“这个数据从哪来?”正译,请说明下为什么好吗?
为什么用is或do。

你可以说where is the date from
或者说where did the date come from
但是不可以说where did the date from

因为如果是be动词作谓语的话,后面可以直接接介宾短语
但是如果不是be动词而是一般动词作谓语的话,在问句里不可以只出现do而不出现中心动词
具体来说where did the date from等于没有谓语动词,属于病句

where is the date from是对的。
只用from要接be动词,如 am, is, are.

第二个句子若改成:where did the date come from就正确了。

举两个简单的例子:
(她来自中国)
1,She is from China.(提问:where is she from?)
2,She comes from China.(提问:where does she come from?)

Where is the data from? this one is right.
