V + 一X是 一X in Chinese
动词＋一X是一X
This spoken frame repeats a verb with 一X on both sides of 是 to accept an immediate, limited course of action. It can mean taking one day or one task at a time. The repeated slots preserve the same verb and measure phrase rather than introducing a new predicate.

Read the structure
This spoken frame repeats a verb with 一X on both sides of 是 to accept an immediate, limited course of action. It can mean taking one day or one task at a time. The repeated slots preserve the same verb and measure phrase rather than introducing a new predicate. Keep the model Verb + 一 + Measure/Object + 是 + 一 + Measure/Object visible while you compare each sentence.
日子过得很难，但也不能过一天是一天。
Life is difficult, but we cannot simply take one day as one day.
Choose the right context
Accept handling one unit at a time when the larger task is difficult. Use a repeated verb and matching 一X phrases in colloquial advice. Let the second clause summarize the same limited unit.
事情太多了，能做一件是一件吧。
There is too much to do, so let one completed task count as one task.
Respect the boundary
Do not change the repeated verb in the second slot. Do not omit 是 between the two matching phrases. Do not treat the frame as a universal claim that every task is easy.
能做一件是看一件吧。
(Do one item and see one item.)
Repair the pattern
The second verb changes: The two slots repeat the same action frame; changing 做 to 看 breaks the construction. 是 is omitted: 是 links the first limited unit with the echoed second unit in the official frame.
能做一件是一件吧。
Use the repaired structure without changing the intended meaning.

08 / QUESTIONS
V + 一X是 一X Questions
Is this a formal written pattern?
It is a conversational fixed frame. Use it in advice or coping talk, not as a neutral mathematical identity.
Does it promise the task will be finished?
No. The frame accepts a manageable unit at a time; the surrounding clause supplies any promise or encouragement.
